PPARGC1A and hepatocellular carcinoma: Wang et al59 found that, in patients with hepatocellular carcinoma, miR‐93‐5p can directly target 3'‐UTR in the mRNA of PPARGC1A (also known as PGC‐1a), inhibiting the expression of PPARGC1A, which functions as a coactivator of transcription and a metabolic modulator.
