evolution | the enzyme belongs to the superfamily of flavin adenine dinucleotide (FAD)-dependent amine oxidases | Homo sapiens |
malfunction | both pharmacological inhibition of LSD1 and small interfering RNA (siRNA) knockdown prevents interleukin 1beta-induced H3K9 demethylation at the mPGES-1 promoter as well as concomitant mPGES-1 protein expression. The level of LSD1 expression is elevated in osteoarthritis cartilage | Homo sapiens |
physiological function | LSD1 modulates gene expression through demethylation of either H3K4 or H3K9. H3K9 methylation usually suppresses transcription, whereas H3K4 methylation generally activates transcription. H3K4 methylation is a critical epigenetic marker of transcriptional activation. Lysine-specific demethylase 1-mediated demethylation of histone H3 lysine 9, but not lysine 4, contributes to interleukin 1beta-induced microsomal prostaglandin E synthase 1 (mPGES-1) expression in human osteoarthritic chondrocytes. Levels of di- and trimethylated H3K4 are significantly enhanced after 4 h of interleukin-1beta stimulation, reach a maximum at 12 h, persist through 24 h and decrease at 48 h. In contrast, the level of monomethylated H3K4 remain almost unchanged following interleukin-1beta stimulation. The increase in H3K4 di- and trimethylation by interleukin-1beta at the mPGES-1 promoter paralleles the increased transcription of mPGES-1, suggesting that, in addition to H3K9 demethylation, H3K4 methylation also contributes to interleukin-1beta-induced mPGES-1 expression, the induction of mPGES-1 by interleukin-1beta is associated with H3K4 methylation | Homo sapiens |
