Treatment of human embryonal carcinoma cells with NMM (100 μM for 48 h) led to accumulation of mature miRNA, decreased levels of pluripotency proteins corresponding to Lin28 mRNA targets (OCT4, HMGA1, CCNB1, CDK4, and Lin28A), and decreased levels of two Lin28 mRNA targets (MYC and Lin28). Here, LIN28A is linked to embryonal carcinoma.
