Quick Tips for Validating Antibodies for Chromatin Immunoprecipitation (ChIP)

June 26, 2014 Bailey Kirkpatrick

Researchers rely on high quality antibodies to perform successful chromatin immunoprecipitation (ChIP) experiments. When investigating the protein-DNA interaction of interest, valid and reliable results simply cannot be attained using nonspecific and inefficient antibodies. If the antibody doesn’t come “ChIP-qualified” or “ChIP-grade” from the supplier, there are several tips you can follow to determine if it’s likely to perform well in ChIP and won’t pull down distracting material to get in the way of a successful study. Carry out the standard [more…]

Dad’s Drinking Could Epigenetically Affect Son’s Sensitivity and Preference for Alcohol

June 18, 2014 Bailey Kirkpatrick

According to a new study from University of Pittsburgh School of Medicine, a father’s excessive drinking behavior could set up his son for , even before conception. Results published in PLOS ONE demonstrate that mice show more sensitivity to alcohol’s effects and are less likely to drink it if their fathers were chronically exposed to the substance before mating. This recent animal study adds to the evidence linking heredity and the propensity for alcohol abuse. Previous studies support the inheritance of [more…]

Epigenetic Change Tied to Hardening of the Arteries

June 11, 2014 Bailey Kirkpatrick

New research suggests that when patterns of blood flow are disturbed, epigenetic changes occur to the genes in the cells lining blood vessels, contributing to hardening of the arteries, otherwise known as atherosclerosis. Characterized by the accumulation of inflammatory cells and fats in arteries, this disease often precedes strokes and heart attacks. Blood flow and the natural curves of the arteries are known to dictate where atherosclerotic plaques develop. Along with his colleagues, Hanjoong Jo, a biomedical engineer and professor [more…]

Do We Already Have A Drug That Could Epigenetically Erase Traumatic Memories?

June 4, 2014 Bailey Kirkpatrick

Scientists at the Virginia Commonwealth University School of Medicine discovered that the drug fingolimod, which is used to treat multiple sclerosis (MS), could potentially benefit individuals who wish to get rid of painful and traumatic memories. While MS is still not entirely understood, the disease involves a process that is immune-mediated in which the immune system attacks healthy parts of the body, namely the central nervous system – the spinal cord, brain, and optic nerves. Fingolimod, or FTY720, is a [more…]
