OBJECTIVE
The ubiquinol cytochrome c reductase UQCRFS1 is a key subunit of the cytochrome bc1 complex (complex III) of the mitochondrial respiratory chain. The purpose of this study is to evaluate the significance of the ubiquinol cytochrome c reductase UQCRFS1 gene amplification in primary breast
Mitochondriopathy is emerging as a new cancer theory; however, the relevance of mitochondrial pathobiology in breast cancer has not yet been completely explored. Herein we report on altered expression levels of the oxidative phosphorylation system (OXPHOS) subunits, mitochondrial structural injury
Withaferin A (WA), a steroidal lactone derived from a medicinal plant (Withania somnifera), inhibits cancer development in transgenic and chemically-induced rodent models of breast cancer but the underlying mechanism is not fully grasped. We have shown previously that WA treatment causes apoptotic
Mitochondria are dynamic intracellular organelles playing a central role in cell metabolism by generating ATP, through the oxidative phosphorylation system (OXPHOS). Altered mitochondrial functions have been identified as causative or contributing factors in some degenerative diseases and are
Tamoxifen (and 4-hydroxytamoxifen), a nonsteroidal triphenylethylene antiestrogenic drug widely used in the treatment of breast cancer, interacts strongly with the respiratory chain of isolated rat liver mitochondria. The drug acts as both an uncoupling agent and a powerful inhibitor of electron
We previously reported the identification of a novel zinc-finger gene, designated ZSG, fused to Ewing sarcoma gene (EWS) by a submicroscopic paracentric inversion of 22q12 in a small round cell sarcoma presenting a translocation t(1;22)(p34;q12). We report here the molecular cloning and
