The binding of miR-892a to a specific site in CYP1A1 leads to a reduction in CYP1A1 protein levels, which in turn can modulate the cellular response to carcinogens such as benzo(a)pyrene. Notably, the exposure to benzo(a)pyrene itself results in decreased miR-892a levels, suggesting a feedback loop that may influence both detoxification processes and the maintenance of cell viability under toxic stress conditions."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nIn parallel, emerging insights into gastric cancer have highlighted that aberrant expression of miR-892a might contribute to tumor progression.
