New research on the biological basis of addiction has found that the critical epigenetic enzyme histone deacetylase 5 (HDAC5) limits the expression of the gene Scn4b, regulating neuronal activity and thereby the formation of strong drug-related memories, which can trigger relapse in individuals with substance use disorders (SUDs). The study in Biological Psychiatry, published by Elsevier, detailing these epigenetic mechanisms in the brain, uncovers a new molecular target for the development of novel SUD treatments.
A new study by researchers from the University of Chicago combines genetic data and improved computational tools to look more closely at GWAS results for both adult-onset and childhood-onset asthma. The research identified many genetic variants with a high likelihood of having a causal effect on both types of asthma, paving the way for further studies to target the genes connected to these variants as potential treatments.
