Actions biochimiques/physiologiques

A-395 is a potent and selective chemical probe for the polycomb protein EED (embryonic ectoderm development), an essential component of Polycomb repressive complex 2 (PRC2), involved in transcriptional repression through methylation of histone H3K27. A-395 has been found to bind to EED in vitro with a Ki value of 0.4 nM, inhibit the PRC2 complex with an IC50 value 34 nM for methylation of H3K27, and have >100-fold selectivity over other histone methyltransferases and non-epigenetic targets. In RD rhabdoid tumor cell line A-395 inhibited the PRC2 complex with an IC50 value of 90 nM, inhibiting the formation of H3K27me3. For characterization details of A-395, please visit the A-395 probe summary on the Structural Genomics Consortium (SGC) website.

A-395N is the negative control for the active enantiomer, A-395. A-395N is available from Sigma. To learn more about and purchase A-395N, click here.

Human health is facing a host of new threats linked to unbalanced diets, including high-sugar diet (HSD), which contributes to the development of both metabolic and behavioral disorders. Studies have shown that diet-induced metabolic dysfunctions can be transmitted to multiple

Epigenetic processes involving long non-coding RNAs regulate endothelial gene expression. However, the underlying regulatory mechanisms causing endothelial dysfunction remain to be elucidated. Enhancer of zeste homolog 2 (EZH2) is an important rheostat of histone H3K27 trimethylation (H3K27me3) that represses endothelial

Embryonic stem cells (ESCs) have transcriptionally permissive chromatin enriched for gene activation-associated histone modifications. A striking exception is DOT1L-mediated H3K79 dimethylation (H3K79me2) that is considered a positive regulator of transcription. We find that ESCs are depleted for H3K79me2 at shared

A hallmark of human immunodeficiency type-1 (HIV) infection is the integration of the viral genome into host chromatin, resulting in a latent reservoir that persists despite antiviral therapy or immune response. Thus, key priorities toward eradication of HIV infection are

Cancers adapt to increasingly potent targeted therapies by reprogramming their phenotype. Here we investigated such a phenomenon in prostate cancer, in which tumours can escape epithelial lineage confinement and transition to a high-plasticity state as an adaptive response to potent
