Targeting Epigenetics and Metabolism to Prevent Cancer Growth
…By modifying certain histones, gene activity can be altered without affecting the underlying genotype, or DNA sequence. The activation of a significant amount of genes can be triggered by epigenetic…
Epigenetic-Based Skin Aging Self-Testing: A Data-Driven Approach to Knowing Your Skin’s “True Age”
…Apple defines SEHI as a progressive decline in the skin’s ability to carry out hydroxylation-dependent epigenetic modifications (often discussed in the context of DNA and histone regulation) that influence repair,…
Low Levels of Alcohol Can Epigenetically Prime the Brain for Addiction
…DNA-protein interactions and altering the transcriptome.” While the study did not indicate what amount of alcohol is safe for rodents, it did point out that low doses of alcohol can…
Histone mimicry: How a SARS-CoV-2 protein functions as an H3 mimic to disrupt host cell epigenetic regulation
…to display increased repressive marks (H3K9me3, H3K27me3) and decreased active marks (H3K9ac) within their H3 ARKS motifs, which correlated with a heterochromatic remodeling of the host DNA and a lower…
Epigenetic Study Reveals That Obscure Protein May Promote Breast Cancer
…of Yin Yang1. Histone acetylation is a mechanism that adds acetyl groups to lysine residues found on the DNA, which loosens the chromatin, leaving it accessible for transcription to turn…
Teen Drinking Is Very Bad…For Brain Development
…thus affecting gene expression without changing the genetic sequence itself. In turn, miRNA expression itself can be regulated epigenetically, such as through DNA methylation and histone modification. microRNA-137 (miR-137) is known…
Epigenetics Involved in Improving COPD Treatment
…deacetylase 2 (HDAC2) – an epigenetic enzyme critical for anti-inflammatory activity. HDACs act as epigenetic erasers that remove the acetyl group from histone proteins on DNA. They influence the structure…
Our Parents’ Lives Could Influence Memories Through Epigenetics
…the F1 and F2 generations to acetophenone was complemented by an enhanced neuroanatomical representation of the Olfr151 pathway. Bisulfite sequencing of sperm DNA from conditioned F0 males and F1 naive…
Air Pollution Found to Alter Important Epigenetic Mark
…histone H3 lysine 9 (H3K9). This particular mark is known to lead to transcriptionally active chromatin, impacting gene expression, DNA repair, and cell differentiation and proliferation, among other cellular processes….
