    Study explores link between cholesterol metabolism and environmental toxicants

    https://cdn.vanderbilt.edu/vu-web/medschool-wpcontent/sites/64/2020/03/23162530/Porter_Updated.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

    Blocking stress-induced relapse

    Mar. 19, 2020, 9:00 AM by Bill Snyder Stress is a precipitating factor for craving and relapse in cocaine use disorder. A part of the brain known as the bed nucleus of the stria terminalis (BNST) has been linked to both anxiety and addiction. Guanfacine, a drug that acts on… Read More

    Triple-negative breast cancer drug therapy shows promise

    Mar. 12, 2020, 9:10 AM by Tom Wilemon Researchers from Vanderbilt-Ingram Cancer Center (VICC) discovered a role for MYCN in triple-negative breast cancer (TNBC), a particularly aggressive form of the disease, and identified a potential intervention for further clinical investigation. MYCN is a well-known oncogene that plays a role in… Read More

    Clues to lung injury in preterm babies

    Mar. 5, 2020, 1:30 PM by Leigh MacMillan Bronchopulmonary dysplasia (BPD) — a form of chronic lung disease — is a leading complication of preterm birth affecting infants born before 32 weeks gestation. Exposure to high levels of oxygen (hyperoxia) plays a role in BPD pathogenesis, but the precise molecular… 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/vu-web/medschool-wpcontent/sites/64/2020/03/18093522/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

    Loss of ‘Jedi’ alters neuron activity

    Mar. 10, 2020, 8:00 AM by Leigh MacMillan The cell bodies of peripheral sensory neurons that respond to and transmit information about stimuli including touch, temperature and pain reside in the dorsal root ganglia (DRG). DRG neuron hyperexcitability is correlated with chronic pain. Bruce Carter’s group… Read More

    Breast cancer study may help predict treatment response

    Feb. 27, 2020, 9:53 AM by Bill Snyder Researchers at Vanderbilt University Medical Center are reporting another advance in the understanding and treatment of triple-negative breast cancer, which is particularly aggressive and difficult to treat. Their findings, detailed in the journal Clinical Cancer Research, offer new hope for identifying… Read More

    Post-transplant diabetes may be reversible: study

    Post-transplantation diabetes mellitus (PTDM), a common complication of immunosuppressive drugs that are given to prevent transplant rejection, may be reversible and at least partially preventable, researchers at Vanderbilt University Medical Center report. “We hope these findings can be translated into clinical research as these results suggest ways that diabetes associated… Read More
