Background: A large number of studies have been published to investigate the association between the null genotype of glutathione S-transferase T1 (GSTT1) with gastric cancer. However, the results were inconsistent and conflicting. The aim of this study was to estimate the relationship between this polymorphism in the GSTT1 gene and gastric cancer risk in Asian populations by meta-analysis.
Materials And Methods: A literature search was performed in PubMed, Embase, Chinese Biomedical database (CBM), Weipu database, Wanfang database, and China National Knowledge Infrastructure database (CNKI). Statistical analysis was conducted by using Review Manager 5.3.
Results: Thirty-nine studies with a total of 7,737 gastric cancer cases and 10,823 controls were included in this meta-analysis. The meta-analysis of total studies showed that the null genotype in GSTT1 was associated with increased risk of gastric cancer in Asians (OR=1.19, 95% CI=1.08-1.31, p=0.0002). Subgroup analysis showed a significant relationship between GSTT1 null genotype and gastric cancer in East-Asians, as well as in subgroup analysis of hospital-based design. On subgroup analysis by smoking status, alcohol status, Helicobacter pylori infection status, and histology type, no significant association of this polymorphism with susceptibility to gastric cancer was found.
Conclusions: In conclusion, the results showed that the null genotype of GSTT1 is significantly associated with an increased risk in gastric cancer in Asian populations.

Microscopic polyangiitis (MPA) affects small and medium vessel, which sometimes leads to arterial aneurysms. In English database, only 15 reports refer to ruptured aneurysms in MPA. We experienced a fatal case with MPA who developed multiple visceral aneurysms, resulting in rupture of the hepatic aneurysm.

tRNA-derived fragments (tRFs) are a newly recognized class of small noncoding RNAs (sncRNAs) that play significant roles in various diseases. The Wnt pathway plays a key role in various physiological processes such as embryonic development, tissue renewal and regeneration. In the regulation of Wnt/β-catenin, Forkhead box k1(FOXK1), Frizzled class receptor 3 (FZD3), and Wnt5b can be targeted and inhibited by three tRFs: tRF3008A targets FOXK1 to inhibit colorectal cancer (CRC), 5'-tiRNAVal targets FZD3 to inhibit breast cancer (BrC), and tRF-22-8BWS7K092 targets Wnt5b to induce ferroptosis in lung cells.

Gastric cancer (GC) is the third leading cause of cancer-related deaths worldwide, with gastrectomy being the primary treatment option. Sepsis, a systemic inflammatory response to infection, may influence tumor growth by creating an immunosuppressive environment conducive to cancer cell proliferation and metastasis. Here, the effect of abdominal infection on tumor growth and metastasis was investigated through the implementation of a peritoneal metastasis model and a subcutaneous tumor model.

Gastric cancer is a common digestive system tumor with a high resistance rate that reduces the sensitivity to chemotherapy. Nutrition therapy is an important adjuvant approach to favor the prognosis of gastric cancer. Dietary amino acids contribute greatly to gastric cancer progression by mediating tumor gene expressions, epigenetics, signal transduction, and metabolic remodeling.

Introduction: Gastric cancer (GC) is the fifth most common cancer globally, and the relationship between type 2 diabetes mellitus (T2DM) and cancer risk remains controversial.
Methods: We performed Mendelian randomization (MR) analysis using publicly available GWAS data to assess the causal relationship between T2DM and GC, validated by heterogeneity and pleiotropy analyses. Transcriptomic data from TCGA and GEO were analyzed to identify common differentially expressed genes (DEGs).
