PINK1 and colorectal carcinoma: A prior study reported that silencing of AFG3L2 leads to the accumulation of PINK1 on the mitochondrial surface and Parkin recruitment, resulting in mitophagy induction.[19] We, therefore, performed transmission electron microscopy (TEM) to analyze the mitochondria in colonocytes from the AOM‐DSS‐induced CRC mouse model (Figure 1A) and in CRC cell lines overexpressing or knocked down for CRABP2.
