ABSTRACT

The annexins(ANX)family is widely present in the cell membrane,cytoplasm or extracellular matrix.As key tumor regulatory molecules,annexins A(ANX A)family can promote or inhibit invasion and metastasis of breast cancer cells by influencing cell membrane and cytoskeleton formation and participating in signaling pathways.ANX A family also plays a role in the apoptosis of breast cancer cells by regulation of pro-apoptotic proteins and cell cycle independent kinases(CDKs)and related pathways.In addition,ANX A family can also promote therapeutic resistance to a large number of drugs.For instance,ANX A1 enhances triple-negative breast cancer resistance by in-ducing epithelial-mesenchymal transformation.ANX A4 induces resistance by forming ANX A4-Fhit complexes and secretion of exosomes containing ANX A6 promotes paclitaxel resistance in breast cancer cells in a YAP1-dependent manner.So ANX A family may be a new target for breast cancer treatment.

ABSTRACT

Objective:To observe the characteristics of the phagocytosis and bactericidal function of multidrug-resistant Mycobacterium tuberculosis(MDR- Mtb)-infected macrophage model, and the changes of the immune response and metabolic function in the process of phagocytosis and bactericidal function, aiming to provide reference for studying the role and mechanism of macrophages in the occurrence and development of multidrug-resistant tuberculosis(MDR-TB). Methods:We established MDR- Mtb and H37Rv-infected macrophage models, and used the colony-forming unit (CFU), Magnetic Luminex ? Assay and Cholesterol Assay kit to observe the effects on phagocytosis and bactericidal function, the secretion of Th1(IL-12/23 p40, IL-27 and TNF-α) and Th2 cytokines (IL-6 and IL-10) and cholesterol metabolism. The data were analyzed by SPSS25.0 software. The data were expressed as Mean± SD and analyzed by t test or F test. P<0.05 was considered statistically significant. Results:(1) After MDR- Mtb-infected macrophages, the intracellular CFU gradually increased and reached the highest at 24 h, while the extracellular CFU gradually decreased and reached the lowest at 24 h. The intracellular CFU at 48 h was lower than that at 24 h, while the extracellular CFU was higher than that at 24 h ( P<0.05). Both intracellular and extracellular CFU at 48 h were close to those at 4 h ( P>0.05). The intracellular CFU was lower than the H37Rv group at 8-48 h, while the extracellular CFU was higher than the H37Rv group ( P<0.05). (2) The level of IL-12/23 p40, IL-27, TNF-α, IL-6 and IL-10 of MDR-TB group were higher than those of blank group ( P<0.05), but the level of TNF-α and IL-6 at 24 h and 48 h were higher than that at 4 h ( P<0.05). IL-12/23 p40 and TNF-α at 48 h and IL-6 at 24 h were lower than those of the H37Rv group, while IL-27 at 48 h was higher than that of the H37Rv group ( P<0.05). (3) The levels of cholesterol of MDR-TB group at 24 h and 48 h were lower than those of 4 h and blank group ( P<0.05), but the level of cholesterol was similar to the H37Rv group at any time ( P>0.05). (4) TNF-α reached the highest when the intracellular CFU reached the highest at 24 h, and IL-6 reached the highest when the intracellular CFU decreased at 48 h. With the decreasing of cholesterol expression, the intracellular CFU increased and then decreased. Conclusions:MDR- Mtb could induce the phagocytosis and bactericidal function of macrophages, increase the expression of Th1 and Th2 cytokines and promote the utilization and consumption of cholesterol, but this function was weaker than that of H37Rv strain.

ABSTRACT

Objective:To explore the feasibility of U6 and Cel-miR-39 as reference genes for quantitative detection of microRNA (miRNA) in cerebrospinal fluid (CSF) of tuberculous meningitis (TBM), and validate the difference of miRNAs between tuberculous and viral meningitis (VM).Methods:The remaining CSF specimens after routine examination were collected in Beijing Chest Hospital of Capital Medical University. A total of 36 TBM and 34 VM patients were enrolled based on the information in the medical records. Total RNA were extracted from the CSF samples, and Taqman based real-time quantitative PCR (RT-CR) analysis were performed to determine the concentration of the miRNAs in CSF. GeNorm, NormFinder and Bestkeeper software were used for stability analysis of the two reference genes. 2 -ΔCt method was used to determine the relative gene expression. Accordance of repeated tests was analyzed by Pearson correlation test. Continuous variables were compared by the t-test. Results:Among the 70 samples, the average cycle threshold (Ct) value of U6 was 30.40±3.30, while the average Ct value of Cel-miR-39 was 21.49±0.70. The expression level of Cel-miR-39 was higher than that of U6. Correlation analysis showed good accordance of the repeated tests among the reference genes and target genes analysis in the randomly selected 10 samples ( r>0.931, P<0.001). Based on the analyses results of the three software, including GeNorm, NormFinder and Bestkeeper, Cel-miR-39 presented better stability in RT-PCR analysis and was more suitable as a reference gene for miRNA quantitative determination in CSF sample of TBM patients. The relative expression levels of the three target miRNAs were calculated using Cel-miR-39 as the reference gene, and miR-126-3p (1.13±0.41 vs 3.34±0.82, t=2.452, P=0.016), miR-130a-3p (0.56±0.10 vs 2.59±0.70, t=2.960, P=0.004) and miR-151a-3p (0.64±0.25 vs 2.11±0.33, t=3.536, P<0.001) were showed significant lower expression levels in CSF in TBM group than that in VM group. Conclusions:Cel-miR-39 can be used as a reference gene for quantitative detection of miRNAs in CSF of TBM patients. Significant differences were detected in expression level of miR-126-3p, miR-130a-3p and miR-151a-3p between TBM and VM group.

ABSTRACT

Objective To discuss the clinicopathological features and prognostic factors of patients with triple negative breast cancer (TNBC) in Shanxi province. Methods The medical records of 958 female TNBC patients who were admitted to Shanxi Provincial Cancer Hospital and the First Hospital of Shanxi Medical University from January 2005 to December 2015 were retrospectively analyzed. The clinicopathological features and prognostic factors were summarized. Results The median age of TNBC patients in Shanxi province was 46 years old (21-87 years old), the median body mass index (BMI) was 24.42 kg/m2 (15.0-37.5 kg/m2), and the rural population was slightly more. The left breast cancer was more than the right breast cancer, and 492 patients (51.4%) were in stage T2. The main histological type was invasive ductal carcinoma. The main surgical method was modified radical mastectomy. Univariate Cox regression analysis showed that the patient's place of residence, fertility status, age at first birth, breastfeeding history, tumor size, American Joint Committee on Cancer Staging, lymph node metastasis, and surgical approach were associated with the risk of death in TNBC patients (all P<0.05);but the BMI, menstrual status, menarche age, and family history were not associated with the risk of death (all P>0.05). Multivariate Cox regression analysis showed that rural residents (HR= 1.46, P= 0.044), positive lymph node metastasis (HR= 2.51, P< 0.01), non-fertility (HR=1.08, P= 0.009) and no surgery (HR= 2.53, P= 0.004) were independent risk factors affecting the risk of death, a history of breastfeeding was a protective factor affecting the risk of death in TNBC patients (HR=0.44, P=0.013). Conclusions In Shanxi province, TNBC is more common in premenopausal women and the main pathological type is invasive ductal carcinoma. Rural population, lymph node positive, non-fertility, and no surgical treatment are independent risk factors for the prognosis of TNBC patients.

ABSTRACT

<p><b>BACKGROUND AND OBJECTIVE</b>Promoter hypermethylation of the RASSF1A gene is among the most abundant epigenetic deregulations in human cancer. The aim of this study is to investigate the relationship between the methylation status of RASSF1A promoter and the prognoses of non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>The methylation status of RASSF1A promoter in 150 NSCLC and 25 non-malignant tissues was determined using a methylation-specific polymerase chain reaction (MSP).</p><p><b>RESULTS</b>RASSF1A promoter hypermethylation was detected in 38.7% (58/150) of NSCLC tissues, but in none of the non-malignant tissues. The patients with hypermethylation of RASSF1A had a poor survival rate, and the relationship between the survival rate and hypermethylation of RASSF1A was statistically significant (P = 0.004). Then by using stepwise Cox proportional hazard regression testing, methylation status of RASSF1A was an independent factor affecting the NSCLC patients' survival (RR = 1.584, 95% CI: 1.040-2.411, P = 0.032).</p><p><b>CONCLUSION</b>The hypermethylation of the RASSF1A promoter may be an independent prognostic factor of NSCLC after operation.</p>
