GATA Binding Protein 3 (GATA-3) expression evaluation as prognostic factor in breast cancer and its relationship with other immunemarkers

Introduction: Breast cancer is the most frequent cancer in which the mortality rate could be decreased by proper management. The GATA3 transcription factor is one of the most frequently mutated genes in breast cancer. Materials and Methods: We studied the immunohistochemical (IHC) expression of estrogen and progesterone receptor, human epidermal growth factor receptor 2, and GATA-3 in 166 radical/partial mastectomy specimens having different histologic grades and stages of breast carcinoma. All samples were obtained from the pathology department of Sina hospital in Tehran-Iran from 2010 to 2016. Results: There was a direct relationship between the luminal subtype carcinoma and higher GATA-3 expression (P-value: 0.001) and between triple-negative carcinoma and lower GATA-3 expression (P-value: 0.001). Moreover, there was a direct relationship between the metastasis rate and the tumor's grade with GATA-3 staining (P-value: 0.000 and 0.001, respectively). Conclusion: GATA-3 expression is related to the histopathologic and prognostic factors. GATA3 can be introduced as an important predictor in breast cancer patients.

Changes in percentage of GATA3+ regulatory T cells and their pathogenic roles in allergic rhinitis / 南方医科大学学报

OBJECTIVE@#To investigate the changes in percentage of GATA3+ regulatory T (Treg) cells in patients with allergic rhinitis (AR) and mouse models.@*METHODS@#The nasal mucosa specimens were obtained from 6 AR patients and 6 control patients for detection of nasal mucosal inflammation. Peripheral blood mononuclear cells (PBMC) were collected from 12 AP patients and 12 control patients to determine the percentages of Treg cells and GATA3+ Treg cells. In a C57BL/6 mouse model of AR, the AR symptom score, peripheral blood OVA-sIgE level, and nasal mucosal inflammation were assessed, and the spleen of mice was collected for detecting the percentages of Treg cells and GATA3+ Treg cells and the expressions of Th2 cytokines.@*RESULTS@#Compared with the control patients, AR patients showed significantly increased eosinophil infiltration and goblet cell proliferation in the nasal mucosa (P < 0.01) and decreased percentages of Treg cells and GATA3+ Treg cells (P < 0.05). The mouse models of AR also had more obvious allergic symptoms, significantly increased OVA-sIgE level in peripheral blood, eosinophil infiltration and goblet cell hyperplasia (P < 0.01), markedly lowered percentages of Treg cells and GATA3+ Treg cells in the spleen (P < 0.01), and increased expressions of IL-4, IL-6 and IL-10 (P < 0.05).@*CONCLUSION@#The percentage of GATA3+ Treg cells is decreased in AR patients and mouse models. GATA3+ Treg cells possibly participate in Th2 cell immune response, both of which are involved in the occurrence and progression of AR, suggesting the potential of GATA3+ Treg cells as a new therapeutic target for AR.

Intraventricular metastasis from carcinoma breast masquerading as choroid plexus neoplasm: A case report

Metastatic tumors in the brain represent the most common type of intracranial neoplasm, comprising 8–10% of all brain tumors. 30% of such tumors are primarily of breast origin in females. Brain parenchymal metastasis is the more common presentation. Intraventricular spread is rare, seen in less than 5% of cases in a metastatic scenario. Here, we report a case of 41-year-old female presenting with intraventricular brain metastasis in a follow-up case of carcinoma breast. Five years post-surgery, the patient presented with complaints of headache. On evaluation, magnetic resonance imaging (MRI) brain showed an intraventricular lesion in the fourth ventricle. She was operated on for the same and the biopsy revealed a tumor with a complex papillary pattern resembling choroid plexus papilloma. On immunohistochemistry (IHC), the tumor cells were positive for cytokeratin 7 (CK7), Epithelial membrane antigen (EMA), GATA3, and mammaglobin favoring a metastasis from breast origin. Hence, a possibility of brain metastasis should be kept in mind in patients presenting with solitary ventricular masses due to the lack of definite radiological characteristics in such locations and histological overlap. Also, organ-specific IHC is a must in today's evidence-based era as is reflected in our case.

Metastasis of mucinous breast carcinoma to the lower alveolus as initial presentation: a diagnostic dilemma

ABSTRACT Metastases in the oral cavity are rare and comprise approximately 1% of all oral malignancies. They usually involve the jaws but may also be found in the soft tissues and salivary glands. Women's most common metastatic malignancies are from primary breast cancers. However, metastasis of mucinous breast carcinoma to the lower alveolus mimicking an aggressive primary malignancy as the initial presentation is exceptionally uncommon. We describe the case of a 66-year-old lady with an ulceroproliferative growth in the right lower alveolus. The lesion eroded the mandible and involved the adjacent soft tissues with no prior history of lesion anywhere else. The lesion clinically mimicked a squamous cell carcinoma and masqueraded as a salivary gland mucinous adenocarcinoma on histopathology. The possibility of a metastatic lesion from the breast rather than a primary of the alveolus was also entertained, aided by the immunohistochemical findings of positivity of the tumor cells for GATA3. A positron emission tomography (PET) scan was undertaken to ascertain the primary site. It detected a hypermetabolic lesion in the left breast, which biopsy revealed mucinous breast carcinoma on histopathological evaluation. Metastasis of breast mucinous carcinoma by the hematogenous route is extremely rare; very few cases have been reported. This case illustrates the diagnostic challenges such a lesion can pose to the surgeon and the pathologist. In the advent of such lesions being the initial clinical presentation, a vigilant clinicopathological and radiological assessment is essential to detect the primary.

Clinical Effect of Bushen Shengxue Prescription on Chronic Aplastic Anemia and Its Effect on T Cell Subsets and Expression of T-bet and GATA3 / 中国实验方剂学杂志

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells （T-bet） and GATA binding protein 3 （GATA3）. MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective， double-blind and randomized control methods， the patients were randomized into three groups： kidney deficiency group， Qi and blood deficiency group， and control group. The three groups were respectively treated with Bushen Shengxue prescription granule， Yiqi Yangxue prescription granule， and Placebo （half the dose of Bushen Shengxue formula granules）. In addition， all of them were given oral cyclosporin and androgen. The treatment lasted 6 months， with 3 months as a course. The blood routine indexes， T cell subsets， and fusion genes T-bet and GATA3 before and after treatment were analyzed， and the safety indexes were monitored. ResultDuring the observation， a total of 75 cases dropped out and 18 were rejected. Finally， 161 cases in the kidney deficiency group， 164 in the Qi and blood deficiency group， and 167 in the control group were included. After 6 months of treatment， the total effective rate was 98.8% （159/161） in the kidney deficiency group， which was higher than the 79.9% （131/164） in the Qi and blood deficiency group （χ2=30.135， P<0.01） and the 61.7% （103/167） in the control group （χ2=70.126， P<0.01）. The total effective rate was higher in the Qi and blood deficiency group than in the control group （χ2=13.232， P<0.01）. After treatment， the hemoglobin （HGB） content increased significantly in three groups （P<0.05） as compared with that before treatment， particularly the kidney deficiency group （P<0.01）. After treatment， the white blood cell （WBC） count and platelet （PLT） count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group （P<0.01）. There was no specific difference in neutrophils （ANC） after treatment among the three groups. At the same time point， the level of T helper type 1 （Th1） cells， Th1/Th2 ratio （P<0.05）， level of CD4+， and CD4+/CD8+ ratio （P<0.05） were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19-， HLA/DR+， and CD25+ between the kidney deficiency group and the other two groups， but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group （P<0.05）. ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism， inhibiting the activity of immune system， modulating T cell subsets， suppressing Th1 and CD4+， and promoting bone marrow hematopoiesis. Moreover， it is safe with little side effects， which is worthy of further promotion.

  Objective  To discuss the significance of genetic diagnosis of children with syndromic hearing loss by using whole-exome sequencing.  Methods  The clinical data of 34 children with sensorineural hearing loss were collected and the whole exons of genome of the children and their parents were sequenced and analyzed.  Results  Genetic causative gene and mutations have been identified in 19 children, including 4 genes (HARS2, USH2A, GATA3, MITF) related to rare syndromic hearing loss. Fifteen children were diagnosed with non-syndromic hearing loss related gene, including 8 cases with GJB2 mutation, 5 cases with SLC26A4 mutation and 2 cases with MYO15A mutation. Mutations of c.435_437del(p.K147del) and c.1403G > C (p.G468A) in gene HARS2, c.11389+1del in gene USH2A, c.1327delA(p.M443Wfs*33) in gene GATA3, c.627C > A(p.C209X) in gene MITF and c.8033_8057delinsG(p.N2678_D2686delinsS) in gene MYO15A were first reported.  Conclusions  Whole-exome sequencing helps the accurate diagnosis of causes of hearing loss, especially for the rare syndromic hearing loss with atypical clinical manifestations. Information from genetic testing may highlight further recommended exams of structure and functions of related organs.

Clinical characteristics and molecular mechanisms of hypoparathyroidism related to GATA3 gene mutation / 中华内科杂志

Objective:To analyze the clinical characteristics and molecular mechanisms of 5 cases of hypoparathyroidism caused by GATA3 gene mutation.Methods:A total of 5 childhood-onset hypoparathyroidism patients with GATA3 mutation were identified from 198 hypoparathyroidism (aged ≤18 years) from 1975 to 2021 in Peking Union Medical College Hospital. Clinical data and biochemical indices of the 5 patients were collected and analyzed retrospectively. Genetic screening was conducted by targeted next-generation sequencing (T-NGS), and bioinformatics analysis was performed to analyze the underline mechanisms.Results:The medium onset age of hypoparathyroidism of the 5 patients was 0.5 (0.1, 1.3) years old, and the time duration from onset to confirmed diagnosis of hypoparathyroidism and hypoparathyroidism- deafness-renal dysplasia syndrome was (7.0±5.2) years and (15.0±5.4) years, respectively. The clinical manifestations included carpopedal spasm accompanied by seizures (5 cases), basal ganglia calcification (5 cases), cataract (1 case), deafness (4 cases), and renal malformations or absence (2 cases). The blood calcium and blood parathormone(PTH) before treatment was (1.65±0.31) mmol/L and (4.64±2.63) ng/L, respectively. The 5 patients carried different heterozygous mutations in GATA3 gene, which caused nonsense mutations, frameshift mutations and splice site mutations, respectively. All the GATA3 gene mutations of the 5 patients are classified as pathogenic or likely pathogenic by the Clin Var database and American College of Medical Genetics and Genomics(ACMG).Conclusions:Attention should be paid to genetic diseases in patients with childhood-onset hypoparathyroidism. The possibility of hypoparathyroidism-deafness-renal dysplasia syndrome should be considered in hypoparathyroidism patients with hearing loss or renal dysplasia. GATA3 gene screening is highly recommended for the confirmation of the diagnosis.

Diagnostic utility of GATA3 immunohistochemical expression in urothelial carcinoma

Aims: This study aims to explore the utility of GATA binding protein 3, a zinc finger transcription factor, expression in genitourinary carcinoma, especially urothelial carcinoma. Settings and Design: It is a prospective study where 74 consecutive cases of urothelial carcinoma along with 10 cases each of prostatic adenocarcinoma (PC) and conventional clear cell renal cell carcinoma were included between August 2016 and January 2017. Methods and Materials: All the cases were histopathologically evaluated and immunohistochemically stained for GATA binding protein 3. Only nuclear positivity was considered as positive. Immunoreactivity score for GATA expression was calculated based on the staining intensity as well as percentage. Statistical Analysis Used: The statistical analysis was done using Statistical Package for Social Sciences Version 15.0 statistical analysis software. P value of <0.05 was considered statistically significance. Results: GATA3 expressions were seen in 77% of the cases of urothelial carcinoma, whereas none of the clear cell renal cell carcinoma and prostatic adenocarcinoma cases was GATA3 positive. GATA3 expression significantly correlated with histological grade and muscle invasion with a weaker or negative expression in high-grade muscle invasive tumor as compared to low-grade and noninvasive neoplasm. Significantly weaker expression of GATA3 was found in cases with severe nuclear pleomorphism, mitosis >10/10 hpf, presence of necrosis, and tumor-infiltrating lymphocytes. No significant change in the status of GATA3 expression was seen in follow-up cases between initial Transurethral resection of bladder tumor (TURBT) and post-recurrence TURBT or radical cystectomy specimens. Conclusions: GATA3 as a sensitive and specific marker for urothelial carcinoma can be effectively used to exclude other genitourinary malignancies, PC, and renal cell carcinoma, at metastatic site. This marker can also be effectively used in predicting the probable grade and invasion in biopsy material with poor morphological characteristics, thereby helping in appropriate management in such cases.

A Review: DNA Methylation of the GATA-3 Gene to Balance T Cells Population During Helminth Infection

Abstract@#Helminth infection has been a severe health issue mostly in the developing countries, where sanitation is not well maintained. The immune mechanism during helminth infection is well understood. The Th2 response is the primary weapon from the immune system to fight against helminth infection. The level of Th2 cells and cytokines are elevated during helminth infection. However, a prolonged Th2 response can cause liver fibrosis and reduce host survival. In the process of T cells differentiation, GATA-3 has a crucial role. It defines the population of Th1 and Th2. The expression of GATA-3 can be regulated through DNA methylation in the CGI sites of the gene. Hence, GATA-3 is able to co-express Th1 and Th2 in one cell, which would give less inflammation effect. This review aims to summarize research about the impact of DNA methylation of the GATA-3 genes to balance T cells population during helminth infection.

Effect of Modified Erchentang on GATA3 and T-bet mRNA Expressions in Lung Tissue of Chronic Obstructive Pulmonary Disease Rats / 中国实验方剂学杂志

Objective: To observe the effect of modified Erchentang on GATA-binding protein-3(GATA3) and T-box expressed in T cells(T-bet) in lung tissue of rats with chronic obstructive pulmonary disease (COPD). Method: Seventy SD rats were randomly divided into seven groups, namely normal group, model group, low, medium and high-dose modified Erchentang group(5,10,20 g ·kg-1), Xiaokechuan group(5 g ·kg-1) and Erchentang group(5 g ·kg-1), with 10 in each group. The rat model of COPD was established by smoking combined with intratracheal dripping of lipopolysaccharide (LPS). After successful modeling, the treatment group was given intragastric administration, and the normal group and the model group were given intragastric administration of equal volume of saline. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentrations of interleukin-10 (IL-10) and interleukin-12 (IL-12) in rat serum. The expressions of GATA3 and T-bet were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The expressions of GATA3 and T-bet in lung tissue were detected by immunohistochemistry (IHC). Result: Compared with the control group, the serum levels of IL-10 in the model group was significantly decreased, while the IL-12 level was significantly increased (PPPPConclusion: Modified Erchentang may reduce the inflammation of lung tissue and improve lung function in COPD rats by reducing IL-12, increasing the content of IL-10, inhibiting the protein and gene expressions of T-bet, and stimulating the protein and gene expressions of GATA3.

HDR syndrome in a Colombian woman with a genital tract malformation: first case report in Latin America / Síndrome HDR en una mujer colombiana con una malformación genitourinaria: primer reporte de caso en Latinoamérica

ABSTRACT Objectives Hypoparathyroidism, sensorineural deafness and renal disease (HDR) syndrome, also known as Barakat syndrome, is an autosomal dominant transmission hereditary disease with a wide range of penetrance and expressivity. Haploinsufficiency of the GATA3 two finger zinc transcription factor is believed to be its cause. This is the first time this orphan disease is reported in Latin America, so the publishing of this report is expected to raise awareness on these types of syndrome, that are usually underdiagnosed in our region, which in turn causes an increase in the years lost to disability (YLDs) rates, as well as higher costs to be assumed by public health systems. Methods A 36-year-old Colombian woman diagnosed with parathyroid gland agenesis was referred from the Endocrinology Service to the Outpatient Service. According to her medical record, in the past she had developed hypocalcaemia, left renal agenesis, hypoparathyroidism, bicornate uterus and sensorineural hearing loss. Through a genetic analysis a pathological mutation on the short arm of the GATA 3 gen (c.404dupC, p Ala136 GlyfsTER 167) was confirmed, which led to a HDR syndrome diagnosis. Discussion This case proves that there is a possibility that mutations described in other continents may be developed by individuals from our region. Regardless of ethnicity, Barakat syndrome should be considered as a possible diagnosis in patients presenting the typical triad that has been described for this condition, since there could be underdiagnosis of this disease in Latin-America due to the lack of knowledge on this condition in said region, and that genetic counseling in these patients is of great importance for the implications of the syndrome in future generations.(AU)

RESUMEN Objetivos El síndrome de hipoparatiroidismo, sordera neurosensorial y displasia renal (HDR) también llamado síndrome de Barakat, es una enfermedad hereditaria de transmisión autosómica dominante con amplia penetrancia y expresividad genética. El síndrome es causado por la haploinsuficiencia del factor de transcripción de dedos de Zinc GATA3. Esta es la primera vez que esta enfermedad huérfana es reportada en latinoamerica, y buscamos generar consciencia de la presencia de estas enfermedades, las cuales usualmente son infradiagnósticadas en nuestro medio y llevan a un aumento de años perdidos por discapacidad y costos para el sistema de salud pública. Métodos Una mujer colombiana de 36 años ingresó a consulta externa de genética referida por el servicio de endocrinología por una agenesia de paratiroides. La paciente tenía antecedentes de hipocalcemia, agenesia renal izquierda, hipoparatiroidismo, sordera neurosensorial y útero bicorneo. Se realizó un análisis genético que confirmo una mutación patológica en el brazo corto del gen GATA3 (c.404dupC, p Ala136 GlyfsTER 167) diagnóstica del síndrome de Barakat. Discusión Este caso demuestra la posibilidad de existencia de mutaciones descritas en otros continentes en nuestra población. Sin importar la etnia, el síndrome de Barakat debe ser estudiado en pacientes que presenten la triada típica, ya que podría existir un infra diagnóstico de la enfermedad secundario al desconocimiento de la misma en Latinoamérica y teniendo en cuenta la importancia que tiene la consejería genética en estos pacientes por las implicaciones de la enfermedad en futuras generaciones.(AU)

Study on the expression and significance of Th1/Th2 cells in the blood of patients with primary gouty arthritis / 中华风湿病学杂志

Objective This study is aimed to investigate the possible role of Th1/Th2 cell in the pathogenesis of primary gout arthritis. Methods The peripheral blood of 21 acute gout patients (AG), 20 intermittent gout patients (IG) and 20 healthy controls (HC) were collected. The clinical data and laboratory indicators of them were enrolled. The percentages of Th1 and Th2 cells were detected by flow cytometry (FCM). The expression of GATA-3, T-bet, IL-4 and interferon (IFN)-γ mRNA in Peripheral blood mononuclear cells (PBMCs) were measured using Real time quantitative polymerase chain reaction (PCR). The protein expression levels of IL-4 and IFN-γ in serum were detected by enzyme-linked immuno sorbent assay (ELISA). The measurement data were compared by one factor analysis of variance test. The correlation between variables was used by Spearman correlation analysis. Results The percentage of Th1 cells in peripheral blood of the AG group was [(23.2 ±8.3)％], and the IG group was [(20.5 ±9.3)％], which were significantly higher (F=6.520, P<0.05) than the percentage of HC group [(14.8±3.8)％]. There was no significant difference between AG group and IG group. The percentage of Th2 cells in peripheral blood of AG group were [(1.9 ±0.7)％], which was significantly lower (F=8.267, P<0.05) than and the percentage of HC group [(3.4±1.8)％] and IG group [(3.3± 1.2)％]. There was no significant difference between the IG group and the HC group. And the proportion of TH1/Th2 cells in the AG group was higher than that of the IG group and the HC group (F=10.406, P<0.01). The expression of T-bet mRNA and IFN-γ mRNA in the AG group and IG group were higher than that in the HC group (F=4.942, P=0.010)、(F=4.458, P=0.016). However, there was no significant difference between IG group and AG group. The expression of GATA-3 mRNA and IL-4 mRNA was significantly lower (F=3.564, P=0.035) (F=5.385, P=0.007) in the AG group and IG group when compared to the HC group. And there was no significant difference between the AG and the IG group. The IFN-γ level increased in the AG and IG group compared to the HC group (F=7.659, P=0.001). The IL-4 levels in the AG group was lower (F=7.099, P=0.002) than those of the IG and HC group. Conclusion Th1 cells in the peripheral blood of patients with GA are increased and accompanied with the decrease of Th2 cells. The results of this study suggest that the imbalance of Th1/Th2 cells in the inflammatory and immune response plays a critical role in the pathogenesis of GA.

Application of immunohistochemistry for p16 and GATA3 and molecular HPV typing in diagnosis of secondary bladder involvement by cervical carcinoma / 中华病理学杂志

Objective@#To investigate the expression of p16 and GATA3 and the detection of human papillomavirus (HPV) in secondary bladder involvement by cervical carcinomas.@*Methods@#Sixteen cases of cervical carcinoma with bladder involvement diagnosed from December 2008 to March 2016 were collected and evaluated by light microscopy, immunohistochemistry for p16 and GATA3 detection and PCR-reverse dot blot for molecular typing of HPV.@*Results@#The age of the patients ranged from 25 to 76 years with median of 52 years. Morphologically, 14 cases(14/16) showed tumor nests infiltrating lamina propria or muscle bundles of the bladder. By immunohistochemistry, 15 cases (15/16) were found to be diffusely and strongly positive for p16, and 1 showed patchy staining pattern. Seven cases (7/7) of corresponding original cervical cancers were also diffusely and strongly positive for p16. GATA3 staining was negative in 13 cases (13/16), and focal weak to moderate positivity was detected in 3 cases.Three cases (3/7) of corresponding original cervical cancers showed focal weak to moderate positivity of GATA3. Fifteen cases (15/16) showed concordant high risk HPV-positivity, including HPV16 in 8 cases and HPV31 in one case. Five cases showed co-infection of HPV16 and HPV18. One case showed co-infection with HPV18 and HPV45.@*Conclusion@#Differential diagnosis by p16 or GATA3 alone is of limited value. Combination of immunohistochemistry for p16 and GATA3 and molecular typing for HPV detection are useful to distinguish primary bladder carcinoma from the secondary involvement by cervical carcinoma.

Transcriptional regulators dictate innate lymphoid cell fates

Research on innate lymphoid cells (ILC) has recently been a fast paced topic of immunological research. As ILCs are able to produce signature Th cytokine, ILCs have garnered considerable attention and have been described to represent the innate counterpart of the CD4 T helper (Th) cells. The development and function of ILCs are precisely regulated by a network of crucial transcription factors, which are also involved in the development or differentiation of conventional natural killer (cNK) cells and T cells. In this review, we will summarize the key transcriptional regulators and their functions through each phases of ILC development. With the phase of ILC lineage commitment, we will focus in particular on the roles of the transcription regulators Id2 and GATA-3, which in collaboration with other transcriptional factors, are critically involved in the generation of ILC fate determined progenitors. Once an ILC lineage has been established, several other transcription factors are required for the specification and functional regulation of distinct mature ILC subsets. Thus, a comprehensive understanding of the interactions and regulatory mechanisms mediated by these transcription factors will help us to further understand how ILCs exert their helper-like functions and bridge the innate and adaptive immunity.

Expressions of TXNIP,STAMP2 and GATA3 and the changes of serum oxidative stress indexes in diabetic patients with breast cancer / 中国糖尿病杂志

Objective To measure the expressions of TXNIP,STAMP2 and GATA3 in diabetes patients with breast cancer and to determine the changes of oxidative stress indexes before and after surgery.Methods The expression levels of TXNIP,STAMP2 and GATA3 mRNA in cancer tissues and adjacent normal tissues were measured in 45 diabetes patients with breast cancer.The levels of serum oxidative stress indexes including MDA,MPO,SOD and TAC were detected and compared before and after surgery.Results The expressions of TXNIP,STAMP2 and GATA3 mRNA and their protein levels in cancer tissues were lower than those in adjacent normal tissues (P<0.05).The positive expression rate of the three indexes were 60%,66.7% and 73.3%,higher than that of TXNIP protein with 2.2% in the adjacent normal tissues(P<0.05).The TXNIP,STAMP2 and GATA3 protein positive rate of breast cancer tissue were related to differentiation,lymph node metastasis and clinical grades (P<0.05).Serum MDA and MPO levels increased first and then decreased.SOD and TAC showed a trend of decrease first and then increase.The turning point is 6 d after surgery.Conclusion TXNIP,STAMP2,GATA3 and serum oxidative stress indicators may be the indicators for diagnosis and treatment of breast cancer in diabetes patients.

Influence of T-bet/GATA-3 to Th1/Th2 of athma rats / 中国免疫学杂志

Objective:To discuss the influence of dexamethasone(DXM) to T-bet/GATA-3 of athma rats.Methods: 30 SD rats were randomly divided into normal group,model group and DXM group,10 rats in each group.Ovalbumin was intraperitoneal injected on the 1th and 8th day and aerosol inhaled from the 15th day,once a day,14 days altogether.Dexamethasone was intraperitoneal injected in 0.5 mg/kg from the 15th day,once per day,a total of 14 times.Flow cytometry tested the content of Th1 and Th2 in spleen and peripheral blood,immunohistochemistry and Western blot measured T-bet and GATA-3 protein expression and RT-PCR tested T-bet and GATA-3 mRNA expression.Results: Compared model group with normal group,the contents of Th1,Th2 in spleen and peripheral blood had a very significant increase(P<0.01);expression of T-bet,GATA-3 protein and mRNA in the lung tissue also had very significant risen(P<0.01).While compared DXM group with model group,T-bet/GATA-3 rose significantly(P<0.05)or very significantly(P<0.01).Conclusion: T-bet/GATA-3 is the key transcription factors that influence the balance of Th1/Th2,while DXM can raise the ratio of T-bet/GATA-3,which reduce the severity of asthma.

GATA3-IL-13 pathway gene polymorphisms are associated with serum IL-13 and asthma / 中国免疫学杂志

Objective:Asthma is a chronic inflammatory respiratory disease .The data show that involvement of the GATA 3-IL-13 gene in asthma is biologically plausible .The objective of this study is investigated the association of GATA 3-IL13 gene polymorphisms and IL-13 levels with asthma;assess the correlations between GATA 3-IL-13 gene SNPs polymorphisms and serum levels of IL-13 in population of Xinjiang (China).Methods:A case group of 279 patients and 277 healthy controls were genotyped to perform using the MassARRAY SNP genotyping system.In 279 asthma patients and 277 controls,IL-13 levels were measured by ELISA.Data were analyzed using the statistical package for social science (SPSS) 22.0 (IBM,NY,USA) and Graph Pad Prism 6.0.Results:Patients were found that IL-13 levels were associated with asthma in asthmatic and the IL-13 ( rs2066960 AA ) , GATA3 ( rs3781093 CC) genotype was associated with a notably increased risk of asthma compared with the CC (rs2066960),TT (rs3781093) genotype (P<0.05).Similarly,IL-13(rs2066960) C-A alleles were significantly associated with risk of asthma (P<0.05).However,the rs3781093 C-T alleles had no obvious differences (P>0.05).In addition,the patients carrying the rs2066960 AA genotype presented with higher IL-13 levels compared to the CC group .Conclusion:This result suggests that the rs 2066960 C-A variant is associated with IL-33 levels in patients with asthma .
