    Study explores link between cholesterol metabolism and environmental toxicants

    https://cdn.vanderbilt.edu/t2-main/medschool-prd/wp-content/uploads/sites/101/2020/03/Porter_Updated-1.mp4   By Stella Child In the last two decades, scientists have found increasing evidence for the contribution of environmental factors to neurodegenerative diseases. Organic solvents, heavy metals, and air pollutants are now all categorized as neurotoxicants, substances that affect the function of the nervous system. A subset of… Read More

  • Two segments of chromatin are shown. Each is made up of eight yellow balls (laid out in a four-by-two pattern) that represent histones and a colorful thread, representing DNA, that goes around the histones; collectively, these are the nucleosomes . The top chromatin has the nucleosomes more spread out than the bottom chromatin. Gene expression on the top chromatin is represented by a green protein that is shooting out segments of RNA. There is no gene expression on the bottom chromatin: the nucleosomes are tightly packed in a line and the DNA has a smattering of red spots throughout, representing methyl groups.

    ATAC-Me attacks knowledge gap in genetics research

    https://cdn.vanderbilt.edu/t2-main/medschool-prd/wp-content/uploads/sites/101/2020/03/Hodges.mp4   By Hillary Layden Most human cells contain roughly 6.5 feet of DNA, which must be tightly compacted to fit within the nucleus. Cells compact DNA by wrapping it around proteins called histones, forming a DNA-protein complex called chromatin. “Closed” chromatin is tightly compacted and cannot interact with… Read More

    Pancreatic islet cells distinct in mice and humans

    By Cassandra Awgulewitsch https://cdn.vanderbilt.edu/t2-main/medschool-prd/wp-content/uploads/sites/101/2020/02/SteinDiabetes.mp4   Researchers in the lab of Roland Stein (Molecular Physiology & Biophysics), along with collaborators at UCSF, NC State, and UPenn, have shown distinct changes in human pancreatic islet cells throughout the course of life and the progression of type 2 diabetes. They also discovered… Read More
