SRP Research Finds Ancestry-Based Differences in Telomere Length Genes
SRP News Page - February 2018
People with different ancestries may inherit telomere length differently, according to a new study from the Columbia University Superfund Research Program (SRP) Center. Telomeres are segments at the end of DNA, and telomere length plays an important role in aging and aging-related diseases. This study provides new information about the genes associated with telomere length across populations and highlights the importance of including diverse populations in genome-wide association studies (GWAS).
Unique opportunities to study health effects of arsenic and more
Environmental Factor - October 2017
In a Sept. 14 talk for the Keystone Science Seminar Series, Habibul Ahsan, M.D., described innovative research approaches, such as building strong networks in the community, to help tackle human health impacts from toxicants in areas where resources are low.
Susceptibility to Arsenic-Induced Skin Lesions Influenced by DNA Differences
Research Brief - September 2017
New research shows that deletions or duplications of long stretches of DNA, also known as copy number variations (CNVs), that occur in several gene locations are associated with a higher risk of developing arsenic-induced skin lesions. Skin lesions are a hallmark of arsenic toxicity that appear relatively early with chronic arsenic exposure. This newly discovered link may help to explain why some people exposed to arsenic develop skin lesions and get sick while others exposed to the same levels do not.
