摘要
Myeloid cell leukemia-1 (Mcl-1) is involved in the regulation of mitochondrial fission and fusion. This report aims to explore whether Mcl-1 can interact with mitochondrial fission factor (Mff) and regulate Mff-mediated mitochondrial fragmentation and apoptosis. Fluorescence images of living cells coexpressing YFP-Mff and CFP-Mcl-1 showed that Mcl-1 markedly inhibited Mff-mediated mitochondrial fragmentation and apoptosis, suggesting that Mcl-1 played a key role in inhibiting mitochondrial fission. The cells coexpressing YFP-Mff and CFP-Mcl-1 exhibited consistent fluorescence resonance energy transfer (FRET) efficiency with that of the cells coexpressing CFP-Mcl-1 and YFP, demonstrating that Mcl-1 did not directly bind to Mff on mitochondria. Collectively, Mcl-1 inhibits Mff-mediated mitochondrial fission and apoptosis not via directly binding to Mff on mitochondria.
