Vicenin-2 Inhibits The Helicobacterium Pylori Infection Associated Gastric Carcinogenic Events Through Modulation Of Pi3k/Akt And Nrf2 Signaling In Ges-1 Cells

Helicobacter pylori (H. pylori), a microbial carcinogen of Gram-negative bacteria, has been recognized to be the highest risk factor for the growth of human gastric cancer (GC). Therefore, the inhibition of the growth rate of H. pylori has been considered an effective vital strategy to prevent GC development. This study highlights the inhibitory effect of vicenin-2 against H. pylori-induced gastric carcinogen signaling in human gastric epithelial cells (GES-1). In vitro cytotoxicity studies reported that 40 mu M of vicenin-2 remarkably protects the gastric cells and this concentration shows 85% cell viability also does not produce toxicity. In addition, vicenin-2 prevents H. pylori-infected increased depletion of antioxidants mediated by reactive oxygen species generation, DNA damage, malondialdehyde, and nuclear fragmentation. Here, we noticed that vicenin-2 remarkably suppressed the expression range of the phosphorylated form of phosphatidylinositol 3-kinase/protein kinase B, phosphorylated p38 kinases, phosphorylated extracellular signal-regulated kinase-1, phosphorylated c-Jun N-terminal kinase, tumor necrosis factor-alpha, interleukin-6, cyclooxygenase-2 in GES-1 infected with H. pylori. Moreover, we observed that vicenin-2 enhanced the antioxidants protein nuclear factor erythroid factor-2 and phosphatase and tensin homolog expression in H. pylori-infected cells. Thus, vicenin-2 prevents the H. pylori-associated infection, and its resistance might be a potential strategy in preventing GC induced by H. pylori.
