additional information | PDH2 knockout in NP cells lentiviral expression of shPHD2, phenotype, overview. TNF-alpha-dependent induction in expression of PHD3, SDC4, MMP13, and ADAMTS5, catabolic marker genes that are hallmark of disc degeneration, is significantly reduced in PHD2 silenced cells. Silencing of PHD2 significantly restores the TNF-alpha-mediated reduction in aggrecan sand collagen II | Rattus norvegicus |

physiological function | PHD2 controls the expression of many of the pro-catabolic and inflammatory genes that are known to be involved with the degenerative cascade and matrix breakdown. Prolyl-4-hydroxylase domain protein 2 controls NF-kappaB/p65 transactivation and enhances the catabolic effects of inflammatory cytokines on cells of the nucleus pulposus, regulatory mechanism of PHD2 function and expression under inflammatory conditions in the nucleus pulposus, overview. PHD2 controls TNF-alpha effects by positively regulating NF-kappaB signaling, whereas NF-kappaB mediates cytokine-dependent PHD2 expression. PHD2 and NF-kappaB form a functional circuit that promotes the catabolic effects of TNF-alpha in the intervertebral disc. PHD2 is a potent regulator of the catabolic activities of TNF-alpha, silencing of PHD2 significantly decreases TNF-alpha-induced expression of catabolic markers including SDC4, MMP-3, MMP-13, and ADAMTS5, as well as several inflammatory cytokines and chemokines, while partially restoring aggrecan and collagen II expression | Homo sapiens |
