Gastric cancer represents a significant disease burden worldwide. The factors that initiate cancer are not well understood. Chronic inflammation such as that triggered by infection is the most significant cause of gastric cancer. In recent years, organoid cultures developed from human and animal adult stem cells have facilitated great advances in our understanding of gastric homeostasis. Organoid models are now being exploited to investigate the role of host genetics and bacterial factors on proliferation and DNA damage in gastric stem cells. The impact of a chronic inflammatory state on gastric stem cells and the stroma has been less well addressed. This review discusses what we have learned from the use of organoid models to investigate cancer initiation, and highlights questions on the contribution of the microbiota, chronic inflammatory milieu, and stromal cells that can now be addressed by more complex coculture models.

Introduction: Several reviews have highlighted that the Patient-Generated Subjective Global Assessment (PG-SGA) is the best diagnostic tool for assessing nutritional status in cancer patients. However, previous meta-analyses summarizing the prevalence of malnutrition and overall survival in patients with gastrointestinal (GI) cancer are quite limited. This study aims to determine the overall prevalence and association between malnutrition, as defined by the PG-SGA, and mortality in adults with GI cancer.

Background: Gamma-glutamyl transferase (GGT) has been shown to have associations with several diseases including cancers. Previous studies have investigated the effect of GGT levels on the gastrointestinal (GI) cancer incidence. We aim to systematically investigate these studies to provide better insights into the interrelationship between GGT and GI cancers.

Objective: The objective of this study is to examine the impact of KW-2478 combined with DDP on colorectal cancer cells both in vitro and in vivo and to elucidate the molecular mechanism of KW-2478 in colorectal cancer.
Methods: qRT-PCR and Western blot were employed to assess HSP90 mRNA and protein expression in normal intestinal epithelial and colorectal cancer cells. DLD-1 and HCT116 were selected for the experiment.

The study by Yang presents a comprehensive investigation into the therapeutic potential of curcumin for gastric cancer (GC). Using network pharmacology, the researchers identified 48 curcumin-related genes, 31 of which overlap with GC targets. Key genes, including , , , , , and , are linked to poor survival in GC patients.
