MRPL21 promotes HCC proliferation through TP53 mutation-induced apoptotic resistance

The specific mechanisms underlying the inhibition of hepatocellular carcinoma (HCC) proliferation and metastasis by mitochondrial apoptosis are not yet fully understood. However, it plays a vital role in suppressing HCC's ability to proliferate and spread. The involvement of MRPL21, a member within the family of mitochondrial ribosomal proteins (MRPs), is well-documented in both cellular apoptosis and energy metabolism. This study aims to explore and unravel the underlying mechanisms through which MRPL21 contributes to mitochondrial apoptosis and resistance against apoptosis in HCC.
