Since mitochondrial fusion and fission work with concert to regulate mitochondrial morphology and functions, it was challenging to quantitatively gauge the direct roles of mitochondrial fusion in apoptosis and cancer development. Right here, we report the introduction of a high-throughput in vitro way to quantify mitochondrial fusion through single mitochondria analysis by a laboratory-built nano-flow cytometer (nFCM). Isolated mitochondria expressing green fluorescent protein (GFP-mito) or discosoma purple fluorescent protein (DsRed-mito) had been mixed together, induced to fuse, and examined by nFCM. A particle exhibiting both green and purple fluorescence had been identified as an event of heterotypic fusion, additionally the efficiency of heterotypic fusion had been used as a surrogate of total fusion effectiveness. The as-developed strategy was used to show the interplay between mitochondrial fusion and apoptosis without the disturbance of fission. We show that cytosolic components presented mitochondrial fusion, and this upregulation was reduced during apoptosis. Combined with translocation of Bid and Bax from cytosol to mitochondria, these conclusions suggest that cytosolic pro-apoptotic Bcl-2 family proteins could possibly be the positive mediators of mitochondrial fusion. On the other hand, fusion also renders mitochondria much more resistant to membrane potential collapse upon apoptosis induction. Our data declare that interruption of mitochondrial fusion could be a potent technique for cancer treatment. Additionally, the as-developed method provides a fruitful strategy to determine fusion inhibitors, including betulinic acid and antimycin A, offering good reasons for their powerful energy in disea
