malfunction | in normal human fibroblasts with a tight hTERT repression, a pharmacological inhibition of LSD1 leads to a weak hTERT expression, and a robust induction of hTERT mRNA occurs when LSD1 and histone deacetylases are both inhibited. Small interference RNA-mediated depletion of both LSD1 and CoREST, a co-repressor in HDAC-containing complexes, synergistically activate hTERT transcription. In cancer cells, inhibition of LSD1 activity or knocking-down of its expression lead to significant increases in levels of hTERT mRNA and telomerase activity, phenotype, overview | Homo sapiens |
physiological function | LSD1 catalyzes the demethylation of mono- and dimethylated histone H3-K4 and also H3-K9, it exhibits diverse transcriptional activities by mediating chromatin reconfiguration. LSD1 represses hTERT transcription via demethylating H3-K4 in normal and cancerous cells, and together with HDACs, participates in the establishment of a stable repression state of the hTERT gene in normal or differentiated malignant cells. Role for LSD1 in controlling hTERT transcription | Homo sapiens |
