[Knockdown mitochondrial transcription factor A (TFAM) inhibits autophagy, proliferation, invasion and migration in human cervical cancer and osteosarcoma cells].

Objective To investigate the effects of mitochondrial transcription factor A (TFAM) on mitochondrial function, autophagy, proliferation, invasion, and migration in cervical cancer HeLa cells and osteosarcoma U2OS cells. Methods TFAM small-interfering RNA (si-TFAM) was transfected to HeLa and U2OS cells for downregulating TFAM expression. Mito-Tracker Red CMXRos staining combined with laser confocal microscopy was used to detect mitochondrial membrane potential (MMP). MitoSOX
