Effects of D-methionine on the hematopoietic system injury in irradiated mice / 中国实验血液学杂志

The aim of this study was to investigate the effects of D-methionine (D-met) on the hematopoietic system injury in irradiated mice. C57BL/6 mice were divided into control group, irradiated group, 300 mg/kg D-met plus irradiation group and 1000 mg/kg D-met plus irradiation group. The control mice received sham irradiation, and the mice in remainder groups were exposed to 7.5 Gy; 1,4,8 Gy and 1 Gy of (137)Cs γ-ray respectively, were used to detect the survival rate, survival rate of bone marrow cells, WBC and its differential counts as well the colony formation ability in irradiated mice, respectively. The D-met was intraperitoneally injected to mice at 30 min before irradiation. The results showed that 300 and 1000 mg/kd D-met did not obviously enhance the survival rate of mice exposed to 7.5 Gy; the 10(-2),10(-3),10(-4) mol/L D-met significantly increased the survival rate of bone marrow cells in mice exposed to 1,4,8 Gy; 300 and 1000 mg/kg D-met even so increased the WBC count of peripheral blood in mice exposed to 1 Gy, but there was no statistical difference as compared with irradiated alone mice, moreover 300 and 1000 mg/kg D-met could obviously promote the colony formation ability of bone marrow cells in irradiated mice, the CFU-GM count was higher than that in 1 Gy irradiated mice (P < 0.05). It is concluded that the D-met can effectively mitigate the marrow cell injury resulted from irradiation, enhance the survival rate of bone marrow cells in irradiated mice, promote the recovery of hematopoietic function from radiation injury in mice.

Integrase interactor 1 regulates proliferation, apoptosis and invasion in gastric cancer cells / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Integrase interactor 1 (INI1), which encodes a component of the ATP-dependent chromatin remodeling hSWI-SNF complex, has been identified as a tumor suppressor in many tumors. Nonetheless, the role of INI1 in gastric tumor progression is not known exactly. The aim of this research was to investigate the effect of INI1 in the carcinogenesis and progression of gastric cancer.</p><p><b>METHODS</b>Gastric tumor tissues with different differentiation levels from clinical gastric carcinoma samples and adjacent control normal tissues were taken. Expression levels of INI1 were detected by quantitative reverse transcriptation-polymerase chain reaction (RT-PCR) and Western blotting. Gastric cancer cell line SGC7901 was transfected with INI1 eukaryotic expressing vector INI1-GFP. Cell proliferation activities were assessed by MTT; cell count and cell cycle were detected by flow cytometry (FCM); cell apoptosis were measured by TUNEL and FCM; cell migration and invasiveness were evaluated by wound healing and transwell assays. Expression levels of INI1 and proliferation-related genes including p16, p21, cyclin D1 and cyclin A, apoptosis genes p53, B-cell non-Hodgkin lymphoma-2 (Bcl-2), Bcl-2-associated x protein (Bax) and caspase-3, and invasion-related genes including intercellular adhesion molecule 1 (ICAM1), matrix metalloproteinase 2 (MMP2), MMP9 and tissue inhibitor of matrix metalloproteinase 1 (TIMP1), were detected by quantitative RT-PCR and Western blotting.</p><p><b>RESULTS</b>INI1 expression levels were lower in gastric carcinoma compared with adjacent control normal tissues.

Objective To investigate the prevalence and spectrum of β-thalassemia mutations in C, uangdong province, and provide a reference for prenatal diagnosis and genetic counseling in this population. Methods Three thousand two hundred and forty-seven blood samples were randomly selected from Guangzhou and 2984 blood samples from Shenzhen from January in 2005 to January in 2009. PCR and reverse dot blot hybridization (RDB) were adopted for detection of β-thalassemia mutations in Guangzhou and Shenzhen city. Results Seven hundred and fifty-one individuals in Guangzhou were found to have β-hemoglobin gene mutations, the detection rate was 23.13%(751/3247); 10 different mutations were identified, namely CD41-42(-TCTT), IVS-Ⅱ-654(C→T), -28(A→G), CDI7(A→T), CD71-72(+A), 13E, IVS-I-1(G→T), CD43(G→T), -29(A→G), CDI4-15(+G), which accounted for 42.53% (336/790) ,25.19% (199/790), 12.66% (100/790), 10.89% (86/790) ,3.29% (26/790), 2.15%(17/790), 1.27%( 10/790), 1.14%(9/790) ,0.51%(4/790) ,0.38%(3/790), respectively; the most common mutation was CD41-42(-TCTT), which accounted for 42.53%(336/790). In Shenzhen, 179 individuals were found to have β-thalassemia mutations, the detection rate was 6.00% (179/2984); 8 different mutations were identified excluding CD43 (G→T) and CD14-15 (+G); the most common mutation, however, was IVS-lI--654(C→T), which accounted for 40.44% (74/183). Conclusions The β-thalassemia mutations in Guangdong province are not only frequent, but also obviously heterogeneous, and the mutations differ from region to region. CD41-42 (-TCTT),ⅣS-Ⅱ-654(C→T), -28(A→G), CD17(A→T) were the 4 predominant mutations.

Polymorphism of DXS15, CA13, CA22 loci in Guangdong normal population / 中国实验血液学杂志

The aim of this study was to investigate the polymorphism of microsatellite repeats DXS15, CA13, CA22 tightly linked to FVIII gene in Guangdong population and its practical value in genetic diagnosis for hemophilia A. The polymerase chain reaction (PCR) and capillary electrophoresis (CE) methods were adopted to test the variability of the 3 microsatellite repeat in Guangdong females, including 111 females, 222 X chromosomes for detecting DXS15 polymorphism; 87 females, 174X chromosomes for detecting CA13 polymorphism; 94 females, 188 X chromosomes for detecting CA22 polymorphism. The results indicated that 11 alleles corresponding to DXS15 were found at this locus with size ranging from 140 to 160 bp. The polymorphism information content (PIC) of this microsatellite repeat was 0.82, heterozygosity was 82%. Six alleles corresponding to CA13 were found, with a size from 145 to 155 bp, and PIC was 0.56, heterozygosity was 56.2%. Four alleles corresponding to CA22 were found with size ranging from 79 to 85 bp, and PIC was 0.41, heterozygosity was 50%. It is concluded that in contrast to the information about Caucasian, the polymorphism of these 3 microsatellites differs from race to race, and region to region. DXS15, CA13 and CA22 are highly polymorphic genetic markers useful for linkage analysis of haemophilia A, which may play a vital role in detection and prenatal diagnosis for hemophilia A.

Interleukin-6 protects cerebellar granule neurons from NMDA-induced neurotoxicity / 生理学报

Interleukin-6 (IL-6) is an important cytokine that participates in inflammation reaction and cell growth and differentiation in the immune and nervous systems. However, the neuroprotection of IL-6 against N-methyl-D-aspartate (NMDA)-induced neurotoxicity and the related underlying mechanisms are still not identified. In the present study, the cultured cerebellar granule neurons (CGNs) from postnatal (8-day) infant rats were chronically exposed to IL-6 for 8 d, and then NMDA (100 micromol/L) was applied to the cultured CGNs for 30 min. Methyl-thiazole-tetrazolium (MTT) assay, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) method and confocal laser scanning microscope (CLSM) were used to detect neuronal vitality, apoptosis and dynamic changes of intracellular Ca(2+) levels in the neurons, respectively. Anti-gp130 monoclonal antibody (75 ng/mL) was employed to the cultured CGNs with IL-6 to inhibit IL-6 activity so as to evaluate the role of gp130 (a 130 kDa glucoprotein transducing IL-6 signal) in mediating IL-6 neuroprotection. Western blot was used to measure the expressions of phospho-signal transducer and activator of transcription 3 (STAT3) and phospho-extracellular signal regulated kinase 1/2 (ERK1/2) in the cultured CGNs. The NMDA stimulation of the cultured CGNs without IL-6 pretreatment resulted in a significant reduction of the neuronal vitality, notable enhancement of the neuronal apoptosis and intracellular Ca(2+) overload in the neurons. The NMDA stimulation of the CGNs chronically pretreated with IL-6 caused a remarkable increase in the neuronal vitality, marked suppression of neuronal apoptosis and intracellular Ca(2+) overload in the neurons, compared with that in the control neurons without IL-6 pretreatment. Furthermore, anti-gp130 antibody blocked the inhibitory effect of IL-6 on NMDA-induced intracellular Ca(2+) overload in the neurons. The levels of phospho-STAT3 and phospho-ERK1/2 were significantly higher in IL-6-pretreated CGNs than those in IL-6-untreated neurons. The results suggest that chronic IL-6 pretreatment of CGNs protects the neurons against NMDA-induced neurotoxicity. The neuroprotective effect of IL-6 is closely related to its suppression of NMDA-induced intracellular Ca(2+) overload and is possibly mediated by gp130/JAK-STAT3 and gp130/RAS-ERK1/2 transduction pathways.
