Non-targeting control or HDAC3 siRNA (Dharmacon, Lafayette, CO) was combined with Lipofectamine 2000 reagent in OptiMEM at a 100 nM final concentration. Seventy-two hours post-transfection RNA was isolated and subjected to reverse-transcription and quantitative real-time PCR. Core subunits are histone deacetylase 3 (HDAC3), nuclear receptor co-repressor (NCOR, also known as NCOR1), and silencing mediator of retinoic acid and thyroid hormone receptor (SMRT, also known as NCOR2). Thus, the complex is usually referred to as the HDAC3 complex, the NCOR/SMRT complex, or simply as NR-co-repressor complex.

Druid, by tej nietuzinkowości było mało, to i owo wiedział o mitochondriach i powiedział coś ciekawego: poprzez nie [mitochondria], tak jak przez dziurkę od klucza, można zobaczyć o co w tym wszystkim tak naprawdę chodzi. The nuclear receptor coactivator 1 (NCOA1) is a transcriptional coregulatory protein that contains several nuclear receptor interacting domains and an intrinsic histone acetyltransferase activity. NCOA1 is recruited to DNA promotion sites by ligand-activated nuclear receptors.
