Can you imagine uttering that phrase in the future? Yep.
“… transgenic mice with increased Setdb1 expression in adult forebrain neurons show antidepressant-like phenotypes in behavioral paradigms for anhedonia, despair and learned helplessness.”
SETDB1 is a protein that helps methylate lysine #9 on the histone H3 DNA binding protein … which leads to DNA CpG methylation … which leads to repression of the NMDA receptor subunit, NR2B/Grin2b … which leads to the anti-depressant-like phenotype.
Recall that 60% of CpGs are methylated and that, in the brain (unlike other terminally differentiated tissues), these methyl groups are popping on and off a lot … perhaps reflecting an ongoing, constant tuning of the inhibition/excitation balance.
thanks for the pic whaddap.
