ABSTRACT
Objective:To evaluate the effect of long non-coding RNA (lncRNA) nuclear enriched abundant transcript 1 (NEAT1) on the radiosensitivity in breast cancer cells by regulating the miR-149-5p/ glutamic pyruvic transaminase 2 (GPT2) axis.Methods:Real-time reverse transcription PCR (RT-qPCR) was used to detect NEAT1, miR-149-5p and glutamic pyruvic transaminase 2 (GPT2) mRNA levels in human breast cells MCF-10A, and human breast cancer cells MCF-7, MDA-MB-231 and MDA-MB-468, respectively. MCF-7 cells were divided into 0, 2, 4, 6 and 8 Gy irradiation groups. MCF-7 cells were divided into NEAT1 knockdown (si-NEAT1) group and control (si-NC) group, NEAT1 knockdown +miR-149-5p knockdown (si-NEAT1+anti-miR-149-5p) group and control (si-NEAT1+anti-miR-NC) group, NEAT1 knockdown + GPT2 overexpression (si-NEAT1+GPT2) group and control (si-NEAT1+NC) group. On the basis of the above grouping, irradiate each group of cells with 4 Gy radiation for 2 h, denoted as IR+si-NEAT1, IR+si-NC, IR+si-NEAT1+anti-miR-149-5p, IR+si-NEAT1+anti-miR-NC, IR+si-NEAT1+GPT2, IR+si-NEAT1+NC groups. Subsequently, MCF-7 cells were irradiated at a dose of 4 Gy and divided into the IR+si-NEAT1, IR+si-NC, IR+si-NEAT1+anti-miR-149-5p, IR+si-NEAT1+anti-miR-NC, IR+si-NEAT1+GPT2 and IR+si-NEAT1+NC groups. RT-qPCR was used to detect NEAT1, miR-149-5p, GPT2 mRNA levels in cells. Colony formation assay was used to detect cell radiosensitivity. CCK-8 assay was adopted to detect cell proliferation ability. The binding sites of NEAT1 and miR-149-5p were predicted by StarBase database. The binding sites of miR-149-5p and GPT2 were predicted by Targetscan database, and validated by dual luciferase assay. Single factor ANOVA was used for inter-group comparisons. LSD- t test was used for pairwise comparison. Results:Compared with MCF-10A cells, NEAT1 and GPT2 mRNA levels in cell lines were up-regulated, whereas miR-149-5p level was down-regulated (all P<0.05). Compared with the 0 Gy dose group, NEAT1 and GPT2 mRNA levels were down-regulated, while miR-149-5p levels were up-regulated in the 2, 4, 6, and 8 Gy dose groups (all P<0.05). Knockdown of NEAT1 expression or radiation alone could enhance cell radiosensitivity, and reduce cell proliferation ability (all P<0.05). Simultaneous radiation treatment with knockdown of NEAT1 expression could strengthen the above effects upon cells (all P<0.05). Knockdown of miR-149-5p expression or overexpression of GPT2 could partially reverse the aforementioned effects of knockdown of NEAT1 expression (all P<0.05). Conclusion:Knockdown of NEAT1 expression enhances breast cancer cell radiosensitivity, and reduces cell proliferation ability by regulating the miR-149-5p/GPT2 signal axis.

ABSTRACT
Objective: To investigate the role and mechanism of glutamic-pyruvic transaminase 2 (GPT2) on cisplatin resistance in gastric cancer. Methods:The Kaplan Meier-Plotter database was used to analyze the relationship between GPT2 expression and poor prognosis of gastric cancer. The expressions of GPT2 in gastric cancer cells and tissues were detected by quantitative real-time PCR (qPCR), Western blotting and immunohistochemistry (IHC). The cytotoxicity of cisplatin at different concentrations to human gastric cancer cells and normal gastric epithelial cells was detected by CCK-8 assay. GPT2 overexpression and knockdown cell lines were constructed in cisplatin sensitive MKN28 cells and insensitive MKN45 cells, respectively. CCK-8 assay, colony formation assay and Western blotting were performed to evaluate the cellular cytotoxicity, stemness of cancer cells and the changes of key proteins in stemness-related signaling pathways in GPT2 overexpression and knockdown cell lines, respectively. Results:The high expression of GPT2 was negatively correlated with the survival of gastric cancer patients. Gastric cancer cells with high expression of GPT2 were resistant to cisplatin, while cells with low expression of GPT2 were sensitive to cisplatin. Overexpression of GPT2 could decrease the cell sensitivity to cisplatin, nevertheless knockdown of GPT2 could increase the cell sensitivity to cisplatin. Meanwhile, the further study revealed that overexpression of GPT2 could activate the extracellular regulated protein kinases (ERK) signaling pathway, up-regulate the expression of SRY-box 2 (SOX2) and Nanog homeobox (NANOG), and enhance the ability of colony formation, while knockdown of GPT2 could inhibit ERK signaling pathway, reduce the expression of SOX2 and NANOG, and suppress the ability of colony formation. Conclusion:GPT2 expression are related to the sensitivity of cisplatin treatment. Overexpression of GPT2 can increase the resistance of gastric cancer to cisplatin treatment by activating ERK signaling pathway and up-regulating the expression of SOX2 and NANOG.
ABSTRACT
It is critical to regulate the senescence-associated secretory phenotype (SASP) due to its effect on promoting malignant phenotypes and limiting the efficiency of cancer therapy. In this study, we demonstrated that marchantin M (Mar-M, a naturally occurring bisbibenzyl) suppressed pro-inflammatory SASP components which were elevated in chemotherapy-resistant cells. Mar-M treatment attenuated the pro-tumorigenic effects of SASP and enhanced survival in drug-resistant mouse models. No toxicity was detected on normal fibroblast cells or in animals following this treatment. Inactivation of transcription factor EB (TFEB) and nuclear factor-B (NF-B) by Mar-M significantly accounted for its suppression on the components of SASP. Furthermore, inhibition of SASP by Mar-M contributed to a synergistic effect during co-treatment with doxorubicin to lower toxicity and enhance antitumor efficacy. Thus, chemotherapy-driven pro-inflammatory activity, seen to contribute to drug-resistance, is an important target for Mar-M. By decreasing SASP, Mar-M may be a potential approach to overcome tumor malignancy.
ABSTRACT
Objective To clarify the effects of HBV co-infection on liver function of patients with different types of hepatic echinococcosis.Methods We recruited 409 patients diagnosed with hepatic echinococcosis at three hospitals in western regions in China from 2014 to 2015.Venous blood was withdrawn to detect to liver function indications.ELISA was performed to detect HBsAg.We analyzed liver function in patients stratified by different types of hepatic echinococcosis with or without HBV infection.Results The hepatic echinococcosis patients infected with HBV had more severe impairment in liver functions such as reduced albumin and increased transaminase.The patients with hepatic alveolar echinococcosis were more vulnerable to HBV infection compared with those with hepatic cystic echinococcosis (38.4％ vs.86.4％, P<0.05).In addition, liver injury was more severe in patients diagnosed with alveolar hepatic echinococcosis and HBV infection compared with those diagnosed with cystic hepatic echinococcosis and HBV infection (all P<0.05).Conclusion Hepatic alveolar echinococcosis patients co-infected with HBV have worse liver injury compared with those hepatic cystic with HBV. Therefore, they deserve special attention in clinical treatment.

ABSTRACT
Serum from a total of 119 workers from Thailand Tobacco Monopoly Company were studied. The subjects were divided into three groups: control, alcoholic who smoke. The enzymatic activities of serum gamma-glutamyl transferase, alkaline phosphatase, glutamic oxaloacetic transaminase and glutamic pyruvic transaminase were determined. The average enzymatic activity in all three groups was found within normal limits. Individual with alcohol consumption showed higher enzymatic activities of serum gamma-glutamyl transferase (p<0.0005), alkaline phosphatase (p<0.05), glutamic oxaloacetic transaminase (p<0.0005) and glutamic pyruvic transaminase (p<0.0005) when compared with controls. There was no significant difference in the ratio of glutamic oxaloacetic transaminase to glutamic pyruvic transaminase in alcoholics compared with controls. While the ratio of gamma-glutamyl transferase to glutamic oxaloacetic transaminase in alcoholics was significantly higher (p<0.0005) when compared with controls.
ABSTRACT
The level of serum lipid peroxide in rat is increased as the age of rat increased gradually. When the animals were injected with sodium selenite (0.1mg/kg) and vitamin E (4mg/kg) for five weeks the serum lipid peroxide level was decreased, the combined use of sodium selenite and vitamin E could decrease the level of SGPT apparently.
