DNM1L and lip and oral cavity carcinoma: To understand the connection between MTFP1-induced mitochondrial fission and mitophagy in oral cancer cells, we studied mitophagy in DNM1L deficient cells expressing MTFP1 and found that MTFP1 controls mitochondrial fission during CCCP (carbonyl cyanide m-chlorophenylhydrazone)-induced mitophagy.
