BAX and benign prostatic hyperplasia: We also investigated whether EA regulates the expressions of apoptosis-related factors (Bcl-2-associated X protein: Bax, B-cell lymphoma-extra large (Bcl-xL), cytochrome c, caspase 9, and caspase 3), and OXPHOS complexes (ATP5A, UQCRC2, MTCO1, and SDHB), as well as mitochondrial dynamics-related factors (DRP1 and MFN1) in the TP-treated BPH rats.
