Whereas p21WAF-1/Cip1 and p27Kip were differently affected in HUVECs, all agents reduced (p <0.05) expression of cyclins (D3, A, E, B), cyclin-dependent kinase-2 and hyperphosphorylated retinoblastoma protein.
Proliferation inhibition and lactate release were mimicked by rotenone (mitochondrial complex I inhibitor).

Here, we dissect the relationships among mitochondrial function, growth arrest, and apoptosis, reporting that initiation and maintenance of butyrate-mediated p53-independent p21WAF1/Cip1 induction and subsequent G0/G1 arrest require an intact mitochondrial membrane potential (delta psi (mt)) and that the process of dissipation of the delta psi (mt) is then essential for initiation of a butyrate-induced apoptotic cascade.

At the concentrations that in hibited HIF-1 activation, compound 2 inhibited hypoxic induction of HIF-1 target genes (CDKN1A, GLUT-1, and VEGF), tumor angiogenesis in vitro, cell migration, and chemotaxis.
Mechanistic studies indicate that, unlike rotenone and other mitochondrial inhibitors, compound 2 represents the first small molecule that inhibits HIF-1 activation by simultaneously suppressing mitochondrial respiration and disrupting protein translation in vitro.

The p53-dependent gene p21WAF1/CIP1 was also induced by hypoxia in both MCF-7 and IMR-90 cells without affecting the growth rate of either cell line.
Rotenone, an inhibitor of mitochondrial complex I, and 4,4'-diisothiocyanato-stilbene-2,2'-disulfonate, a mitochondrial anion channel inhibitor, also abolished the increase in ROS signal and p53 levels during hypoxia.
