In our recent study, we initially analyzed mitochondrial fission in oral cancer cells and found that MTFP1 knockdown diminishes the levels of the mitochondrial fission protein FIS1 (fission, mitochondrial 1) as well as phosphorylation of DNM1L (dynamin 1 like) at Ser616, which indicates a mitochondrial hyperfusion. This evidence concerns the gene FIS1 and lip and oral cavity carcinoma.
