The administration of insulin to IOSE80, SVOG, COV434, and KGN cells to induce PCOS model in vitro. a qRT-PCR was used for testing lncRNA SNHG12 level in each group of cells; ^♦P < 0.05, ^♦♦P < 0.01 vs. IOSE80 cell group, n = 3 in each group; b qRT-PCR was used for testing lncRNA SNHG12, miR-129, and miR-125b expressions under the different dosages of insulin in SVOG, COV434 and KGN cells; n = 3 in each group; ^▲P < 0.05, ^▲▲P < 0.01 vs. control group
