Objective To investigate the expression of Bcl-2 associated athanogene 3 (BAG3) in cervical cancer tissues and cells and its role in epithelial mesenchymal transition (EMT) of cervical cancer.Methods (1) Cervical cancer samples were collected from September 2015 to March 2017 in the Qilu Hospital of Shandong University and Shangdong Provincial Hospital.While,50 normal tissues were collected from August 2015 to March 2017 in the Dezhou Municiple Hospital,which were obtained from patients with uterine mnyoma underwent hysterectomy and patients with cervical biopsy.Reverse transcription (RT)-PCR and western blot were used to detect the expression of BAG3 mRNA and protein,and their clinical significances were analyzed.(2) The expression of BAG3 mRNA and protein was detected using RT-PCR and western blot method in HeLa and SiHa cell lines and normal cervical epithelial cells.The experiment was divided into two groups,BAG3 small interfering RNA transfected group (st-BAG3) and the control group transfected with small interfering RNA (siRNA).Cell counting kit 8 (CCK-8) analysis was used to detect cell proliferation of two groups.Wound-healing and transwell assay were used to detect the migration and invasion ability of HeLa and SiHa cells.The xenograft model of cervical cancer in nude mice was used to observe the effect of BAG3 on tumor xenografts and the tumor-related biomarkers were tested by western blot.Results (1) The expression levels of BAG3 mRNA and protein in cervical carcinoma tissues were 1.20±0.15 and 1.10±0.16,which were significantly higher than that in normal cervical tissue,0.23± 0.04 and 0.29 ± 0.03 (both P＜0.01).The results showed that the expression levels of BAG3 mRNA and protein were significantly correlated with cervical carcinoma staging and lymph node metastasis (P＜0.05).However,its expression was not conrelated with the patient's age,pathological grade,and diameter of tumor (all P＞0.05).(2) Compared with normal cervical epithelial cells,the expression of BAG3 mRNA and protein levels in HeLa and SiHa cells were significantly increased (P＜0.01),the expression levels of BAG3 mRNA and protein in HeLa and SiHa cells transfected with si-BAG3 were significantly lower than that in control group (all P＜0.01).After post-transfected 72 hours,A value of HeLa and SiHa with transfection were significantly lower than those in control group [(0.88±0.08) vs (1.22±0.13),(0.92±0.09) vs (1.35±0.12);both P＜0.01].After post-transfected 24 hours,the migration level of HeLa and SiHa cells with transfection were significantly lower than those in the control group [(20.1±2.1)％ vs (58.6±5.6)％,and (21.1±2.1)％ vs (61.7± 5.4)％;both P＜0.01].The transmembrane cell number in HeLa and SiHa cells with transfection were 76± 11 and 71±8,which were significantly less than those in control group (131± 12 and 129± 14;both P＜0.01).After the inoculation into nude mice,tumor formation time of HeLa and SiHa cells with transfection were (9.5±0.5) and (10.5 ± 1.3) days,respectively,which were significantly longer than those in control group [(4.5±0.5) and (5.2± 1.1) days;both P＜0.05].Compared with those in the control group,the expression level of Slug,N-cadherin and matrix metalloproteinase-2 (MMP-2) protein in HeLa and SiHa cells with transfected in tumor tissues were significantly decreased (all P＜0.01),while the expression level of E-cadberin protein was significantly increased (P＜0.01).Conclusion BAG3 could be involved in the proliferation,migration and invasion of cervical cancer cells by affecting cervical cancer EMT,and BAG3 may be an effective target for the treatment of cervical cancer.

Objective To investigate the effects of 5-fluorouracil (5-FU) on the distribution, pro-portion and immunosuppressive activities of myeloid-derived suppressor cells (MDSCs) in a mouse model of liver cancer.Methods Orthotopic transplantation of H22 cell line was performed to establish the mouse model of orthotopic liver cancer.Forty mice were randomly divided into four groups (n=10) on the 7th day after transplantation.Three different doses of 5-FU (10 mg/kg, 30 mg/kg and 50mg /kg) and 0.4 ml of PBS were respectively given to the mice in each group for 10 consecutive days .A control group without canc-er cell transplantation was set up correspondingly .The distribution of MDSCs in mice liver tissues was detec-ted by immunohistochemistry .The proportions of MDSCs in spleen tissues were tested by flow cytometry . The levels of IFN-γand Arginase-I ( Arg-I) in serum samples were analyzed by enzyme-linked immunosor-bent assay.The activities of nitric oxide synthetase (NOS) in serum samples were tested by chemical colori-metry.The proliferation of T lymphocytes was assessed by 3-(4,5-Dimethylthiazol-2-yl)-2, 5-diphenyltet-razolium bromide (MTT) test.Results 5-FU reduced the tumor size and alleviated the adhesion between liver tissues and abdominal cavity in mice with liver cancer in a dose-dependent manner .The proportions of MDSCs in liver and spleen tissues from mice in four model groups were significantly higher than those in con - trol group (P<0.05).The highest proportions of MDSCs were observed in PBS treated group , followed by 10 mg/kg of 5-FU treated group , 30 mg/kg of 5-FU treated group and 50 mg/kg of 5-FU treated group .Ex-cept for comparing between PBS treated group and 10 mg/kg of 5-FU treated group, there were significant differences with the proportions of MDSCs in liver tissues among other groups (P<0.05).The levels of Arg-I and the activities of NOS in mice with liver cancer were higher than those in control group (P<0.05).The mice in PBS treated group showed the highest level of Arg-I and the strongest activities of NOS that were de-creased as concentrations of 5-FU increased( P<0.05).The levels of IFN-γin serum samples from mice with liver cancer were lower than those in control group , and the lowest level was detected in PBS treated group.IFN-γlevels were increased as concentrations of 5-FU elevated.Except for comparing between PBS treated group and 10 mg/kg of 5-FU treated group , significant differences with the levels of IFN-γin serum samples (P<0.05) were observed among other groups .No significant differences with the proliferation of T cells were observed among all groups after 24 hours of culture (P>0.05),but that were decreased in model groups than those in control group after 48 hours of culture (P<0.05).T cells from mice in PBS treated group showed the lowest level of proliferation .T cell proliferation was enhanced upon the treatment of 5-FU in a dose-dependent manner .Except for comparing between PBS treated group and 10 mg/kg of 5-FU treated group, significant differences with T cell proliferation were observed among other groups (P<0.05).The proportions of MDSCs in liver and spleen tissues were positively correlated with the levels of Arg -I and the activities of NOS, but negatively correlated with IFN-γlevel and T cell proliferation at the time point of 48 h.Conclusion To a certain extent , 5-FU could reduce the numbers of MDSCs in liver and spleen tis-sues from mice with liver cancer , inhibit immunosuppressive activities of MDSCs and restrain the growth of the tumor in a dose-dependent manner .

BACKGROUND: The death of aging cells is virtually apoptosis. To a certain extent, it can be interpreted as a series of results of gere activities.Therefore, the inhibition of oncogene's expression can lengthen the life span of cells and delay aging of brain tissues.OBJECTIVE: To study the effect of abstragulus mongholicus bung (AMB) on apoptosis of nerve cells and the expression of relevant gene in aging mice brain.DESIGN: Completely randomized design and controlled experiment.SETTING: Department of Biochemistry, School of Basic Medical Sciences of Jiamusi University.MATERIALS: The experiment was conducted at the Experimental Animal Center and Biochemical Laboratory of Jiamusi University from December 2003 to May 2004. Totally 24 healthy Kunming mice were recruited in this study. There were 8 two-month-old mice (young group) and 16 twelve-month-old mice. All the 16 mice were randomized into abstragulus mongholicus bung group and old control group with 8 in each group.METHODS:① AMB group:Mice in AMB group received gastric gavage was provided by the Department of Traditional Chinese Medicine of the First Hospital Affiliated to Jiamusi University, and evaluated by Jiamusi Drug Inspection Bureau. Water decoction was prepared with 2 kg/L raw materials. Mice in old control group and young group were filled with lukewarm boiled water.② All the animals were treated as above for 30 consecutive days before put to death. Their brains were taken out immediately and the middle parts of the brains were removed to fix with neutral formaldehyde. The remaining brain tissues were made into mitochondria suspension. Content of manganese superoxide dismutase (Mn-SOD) and malondialdehyde (MDA) was determined with xanthosine oxidase method and TBA chemical colorimetry. Apoptotic cells (cells with yellow nuclei were positive ones) were assayed with in situ end-labeling (ISEL) and expression of bcl-2 gene was assayed with immunohistochemical method. The cells stained brown were positive ones. A total of 400 cells were counted under the 400× microscope. We graded the samples according to the percentage of the positive cells: the number of positive cells ＜ 5% -; 5%-10％ +; 11％-50％ ++; ＞ 51％ ().③ Grade and quantitative data were compared with rank sum test and t-test.MAIN OUTCOME MEASURES: Effects of AMB on the rate of neu-ronal apoptosis, the activity of Mn-SOD, the concentration of MDA in mitochondria, and the intensity of the expression of bcl-2 gene.RESULTS: Totally 24 mice entered the final analysis.① Content of MnSOD was higher in young group and AMB group than in old control group (P＜0.05).② Concentration of MDA and apoptotic rate in young group and AMB group were lower than those in old control group (P ＜ 0.01).③Expression of bcl-2 gene was significantly different in young group and AMB group from that in old control group (P ＜ 0.01).CONCLUSION: AMB is found to be able to obviously inhibit neuronal apoptosis in aging mice brain by affecting the activity of Mn-SOD, the concentration of MDA and the expression of bcl-2.
