PKM and polycystic ovary syndrome: To further assess the relationship between SNHG12 and glycolysis-related genes, correlation analysis was utilized and the results showed that SNHG12 expression was positively correlated with the levels of HK2 (r = 0.368, P < 0.001; Figure 1F), LDHA (r = 0.442, P = 0.004; Figure 1G), and PKM2 (r = 0.346, P < 0.001; Figure 1H), suggesting that SNHG12 may be closely linked to glycolytic activity in the GCs of PCOS.
