Objective: This study examined whether the two polymorphisms of GPX1 (198Pro--> Leu) and TXNRD2 (370Lys-->Arg) contributed alone or in combination, to the risk of gastric cancer development.

Methods: A total of 361 patients with gastric cancer and 363 cancer-free controls were recruited and their genotypes of the two polymorphisms were determined by polymerase chain reaction-based restrictive fragment length polymorphism (PCR-RFLP) method. Odds ratio (OR) and 95% confidence interval (CI) were computed using unconditional logistic regression model.

Results: GPX1 and TXNRD2 polymorphisms individually were not associated with the risk of gastric cancer. Gene-gene interaction of GPX1 and TXNRD2 polymorphisms decreased the risk of gastric cancer. Carrying the protective genotype might decrease the risk at 62% (OR = 0.38, 95% CI = 0.26-0.55, P < 0.001) as compared with the risk genotype.

Conclusion: The GPX1 198 Pro/Pro and TXNRD2 370Arg/Arg genotypes might be associated with the genetic susceptibility of gastric cancer.

Hazard rates of recurrence for gastric cancer after curative resection: implications for postoperative surveillance.

Gastric Cancer

December 2024

Department of Gastrointestinal Surgery, Kanagawa Cancer Center, 2-3-2 Nakao, Asahi Ward, Yokohama, Kanagawa, 241-8515, Japan.

Background: Identifying the most effective postoperative surveillance interval in patients with gastric cancer (GC) remains challenging. To elucidate a logical and effective surveillance schedule, we analyzed GC recurrence risk trends after gastrectomy using the hazard function.

Methods: We retrospectively reviewed the medical records of 2503 patients who underwent curative GC resection between 2000 and 2018.

Purpose: This study aimed to investigate that AKT1-Mediated NOTCH1 phosphorylation promotes gastric cancer (GC) progression via targeted regulation of IRS-1 transcription.

Methods: The study utilized databases such as PhosphositePlus, TRANSFAC, CHEA, GPS 5.0, and TCGA, along with experimental techniques including Western Blot, co-IP, in vitro kinase assay, construction of lentiviral overexpression and silencing vectors, immunoprecipitation, modified proteomics, immunofluorescence, ChIP-PCR, EdU assay, Transwell assay, and scratch assay to investigate the effects of AKT1-induced Notch1 phosphorylation on cell proliferation, invasion and migration in vitro, as well as growth and epithelial-mesenchymal transition (EMT) in vivo.

Gastric cancer (GC) is one of the most common cancers worldwide, with increasing incidence and mortality rates. It is typically diagnosed at advanced stages, leading to a poor prognosis. GC is a highly heterogeneous disease and its progression is associated with complex interplay between genetic and environmental factors.
