Tumor-associated macrophages (TAMs), which play a crucial role in the tumor microenvironment, can be divided into M1 and M2 phenotypes, these phenotypes may exert opposite effects on the prognoses of patients with gastric cancer (GC). The association between TAMs and GC is contentious. Thus, a meta-analysis of 12 studies (incorporating 1388 patients) retrieved from the Cochrane Library, PubMed ... more

We conducted a case-control study to investigate the association between the interleukin-10 (IL-10) C819T polymorphism and susceptibility to gastric cancer in a Chinese population. A total of 157 patients with gastric cancer and 249 controls were consecutively enrolled from the Guizhou Provincial People's Hospital between October 2012 and February 2015. The polymerase chain reaction- ... more

Gastric cancer is the fourth commonly diagnosed cancer and the second most frequent cause of cancer death worldwide. Genetic variations in ADH1B and ALDH2 may alter the function and activity of the corresponding enzymes, leading to differences in acetaldehyde exposure between drinkers. Cytochrome P4502E1 (CYP4502E1) is a phase I enzyme that plays an important role in metabolizing nitrosamine ... more

Glutathione S-transferase (GST) is an important member of phase II metabolic enzymes; GSTM1, GSTT1, and GSTP1 belong to three subfamilies of the GST enzyme. Polymorphisms in GSTM1, GSTT1, and GSTP1 could affect detoxification processes, and increase individuals' susceptibility to cancers. We aimed to investigate the association between GSTM1, GSTT1, and GSTP1 polymorphisms and the risk of ... more

Association of signal-induced proliferation-associated 1 (SIPA) gene and protein expression with gastric cancer development was examined. SIPA1 mRNA and protein levels were determined by real-time quantitative polymerase chain reaction and western blot, respectively, in 40 gastric tumor and tumor-adjacent normal tissues. SIPA1, VEGF-A, and FVIII levels in 60 gastric tumor and 40 tumor-adjacent ... more

We aimed to analyze gastric signet ring cell (SRC) carcinoma subtypes by investigating gastric and intestinal phenotypic marker expression, and explore the relationship between phenotype and K-ras mutation. Immunohistochemistry was performed on 163 SRC carcinoma patient specimens to detect gastric (MUC1, MUC5AC, and MUC6) and intestinal (MUC2 and CDX2) phenotypic markers, and tumors were ... more

Human colon cancer cells; Multi-Drug Resistance; Oxaliplatin

Oxaliplatin (L-OHP) is one of the most commonly used anticancer drugs in adjuvant treatment of colon cancer after complete resection of the primary tumor and treatment of metastatic colorectal cancer. Cancer cells eventually become resistant to L-OHP, which diminishes its curative effect. However, the mechanism of action of L-OHP remains unknown. In this study, an L-OHP-resistant human ... more
