Ovarian carcinoma is the most lethal gynecologic tumor worldwide. Despite having
developed molecular diagnostic tools and targeted therapies over the past few
decades, patient survival is still quite poor. Numerous studies suggest that
microRNAs are key regulators of many fundamental biological processes, including
neoplasia and tumor progression. miR-222 is one of those miRNAs that has
attracted much attention for its multiple roles in human diseases, especially
cancer. The potential role of microRNAs in ovarian cancer has attracted much
attention in recent years. Some of these microRNAs have been suggested as
potential therapeutic targets for EOC patients. In this study, we sought to
investigate the biologic functions of miR-222-3p in EOC carcinogenesis. Herein,
we examined the expression of miR-222-3p in EOC patients, mouse models and cell
lines, and found that higher expression of miR-222-3p was associated with better
overall survival in EOC patients, and its level was negatively correlated with
tumor growth in vivo. Furthermore, in-vitro experiments indicated that miR-222-3p
inhibited EOC cell proliferation and migration, and decreased the phosphorylation
of AKT. We identified GNAI2 as a target of miR-222-3p. We also found that GNAI2
promoted EOC cell proliferation, and is an activator of the PI3K/AKT pathway. We
describe the characterization of a novel regulatory axis in ovarian cancer cells,
miR-222-3p/GNAI2/AKT and its potential application as a therapeutic target for
EOC patients.
