Nobiletin Inhibits Helicobacterium pylori Infection-Induced Gastric Carcinogenic Signaling by Blocking Inflammation, Apoptosis, and Mitogen-Activated Protein Kinase Events in Gastric Epithelial-1 Cells.

Nobiletin Inhibits Helicobacterium pylori Infection-Induced Gastric Carcinogenic Signaling by Blocking Inflammation, Apoptosis, and Mitogen-Activated Protein Kinase Events in Gastric Epithelial-1 Cells. J Environ Pathol Toxicol Oncol. 2020;39(1):77-88 Authors: Ouyang Y, Li L, Ling P Abstract Helicobacter pylori causes a Gram-negative bacterial infection that can increase the risk of gastric cancer. Consequently, meticulous prevention of an H. pylori infection is significant for averting gastric cancer in humans. Nobiletin, an important dietary polymethoxylated flavonoid in citrus fruits, possesses multidimensional pharmaceutical properties, including its ability to act as an anticancer, anti-inflammatory, antioxidative, cardiovascularly defensive, neuroprotective, and antimetabolic agent. Our study evaluates the role of nobiletin in inflammation-mediated gastric carcinogenic signaling of H. pylori-arbitrated coculture in the human gastric epithelial (GES)-1 cell line. Our results show that the culture system of H. pylori-tainted GES-1 cells demonstrates maximum fabrication of reactive oxygen species (ROS), mediating DNA injury and augmenting nuclear fragmentations. Treatment with nobiletin reduces ROS levels and apoptotic morphological changes by dual staining and decreases levels of lipid peroxides and glutathione content in H. pylori-infected GES-1 cells.
