(Press-News.org) HOUSTON ― Sharon Dent, Ph.D., professor of Epigenetics and Molecular Carcinogenesis at The University of Texas MD Anderson Cancer Center, has been elected to the National Academy of Sciences (NAS). Dent is a global leader in the field of chromatin research whose foundational work has helped define the role of chromatin in cancer growth and development.
Dent is one of 120 members and 24 international members elected this year in recognition of their distinguished and continuing achievements in original research. The NAS, established in 1863 by President Abraham Lincoln, is a private, nonprofit society of distinguished scholars engaged in scientific and engineering research.
With her election, Dent joins eight previously elected MD Anderson scientists in the NAS, including James P. Allison, Ph.D., Neal Copeland, Ph.D., Ronald A. DePinho, M.D., Nancy Jenkins, Ph.D., V. Craig Jordan, Ph.D., Guillermina (Gigi) Lozano, Ph.D., Helen Piwnica-Worms, Ph.D., and Richard Wood, Ph.D.
“Being elected to the National Academy of Sciences is a well-deserved recognition of Dr. Dent’s tremendous research contributions over the years,” said Peter WT Pisters, M.D., president of MD Anderson. “Her discoveries have furthered our understanding of cancer mutations, aiding in the future development of highly targeted therapies. We are proud to have her as a valued member of the MD Anderson research community and we celebrate her outstanding work to advance our mission to end cancer.”
Dent’s work is in the field of epigenetics, which studies how human behaviors and the environment can cause changes that affect genes and lead to inherited traits without changing the DNA sequence. Unlike genetic mutations, epigenetic changes, which alter how the body reads a particular DNA sequence, are reversible.
Most of the work in the Dent laboratory focuses on understanding the role of chromatin and chromatin-modifying proteins in regulating gene expression, genome integrity and other essential cellular processes. Chromatin is a mixture of DNA and histone proteins that form our chromosomes, and this complex can receive and transmit signals from the body’s cells. In particular, Dent and her colleagues study various components of the SAGA chromatin-modifying complex, such as Gcn5 – a histone acetyltransferase – to examine how certain mutations lead to abnormal chromatin folding and subsequent diseases, such as cancer.
“This is an enormous honor,” Dent said. “It highlights the impact of the discoveries made by all of the hard-working and brilliant members of my lab over the past 31 years, and I am truly grateful for this distinction.”
Dent’s research helps scientists and clinicians develop therapeutic strategies to target processes that can treat cancer. Most recently, she and her colleagues showed that the SAGA complex contains specific oncoproteins, MYC and MAF, which promote the transformation of normal cells into tumors by dysregulating the signaling pathways involved in cell growth. Targeting the SAGA complex could lead to new ways to treat multiple myeloma and other cancers, such as lymphoma and neuroblastoma.
Dent graduated magna cum laude from the University of North Texas with a Bachelor of Science in biochemistry, and earned her Ph.D. in biochemistry from Rice University. After a postdoctoral fellowship at Rice University and a fellowship at the National Institutes of Health’s Laboratory of Cellular & Developmental Biology, she joined MD Anderson as an assistant professor in the Department of Biochemistry and Molecular Biology in 1993. She was promoted to professor in 2004 and, only three years later, became the founding director of the Center for Cancer Epigenetics. She served as chair of the Department of Epigenetics and Molecular Carcinogenesis from 2010 to 2023 and as ad interim dean of the MD Anderson UTHealth Houston Graduate School of Biomedical Sciences from 2022 to 2024.
Dent was elected as a member of the American Academy of Arts and Sciences and as a fellow of the American Association for the Advancement of Science (AAAS). Her honors include induction into the Greater Houston Women’s Chamber of Commerce Hall of Fame, the John Mendelsohn Award for Faculty Leadership, the Ruth Legett Jones Distinguished Chair in the Department of Epigenetics and Molecular Carcinogenesis, and the President’s Leadership Award from MD Anderson.
“Dr. Dent’s research has been transformative in the field of epigenetics, revealing unexpected functions beyond transcriptional regulation in cellular processes. We congratulate her on being included in this prestigious community of scientists,” said Giulio Draetta, M.D., Ph.D., chief scientific officer of MD Anderson. “Her work embodies the spirit of MD Anderson’s research ecosystem, which drives breakthroughs that can significantly improve the lives of patients with cancer.”

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, MAY 1, 2024
MINNEAPOLIS – Children and teens may experience nonmotor seizures for months or years before being seen in an emergency department for a more obvious seizure that includes convulsions, according to a study published in the May 1, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology. Even then, the history of nonmotor seizures may not be recognized.
“Early diagnosis of epilepsy is of the utmost importance because epileptic seizures can lead to injury and even death,” said study author Jacqueline French, MD, of NYU Grossman School of Medicine ...
A subtle type of seizure goes undetected two thirds of the time in pediatric emergency departments, a new study shows.
The work focuses on “nonmotor” seizures, which cause children to “zone out” and stare into space or fidget. They may also feel sudden changes in emotions, thoughts, or sensations, as opposed to motor seizures, which cause muscles to move in abrupt, jerking motions.
According to the authors, improving recognition of nonmotor seizures may speed up the diagnosis and treatment of epilepsy in children, ...
(MEMPHIS, Tenn. – May 01, 2024) St. Jude Children’s Research Hospital scientists have identified specific DNA variants in the non-coding regions of the genome contributing to chemotherapy resistance in acute lymphoblastic leukemia (ALL). The results guided the team to unravel the mechanism behind a previously unknown contributor to therapeutic resistance. The discovery was enabled by combining new technologies to overcome previous limitations in understanding the non-coding genome, which could be adapted to other ...
HUNTINGTON, W.Va. – The Marshall University Joan C. Edwards School of Medicine is now accepting applicants for an observational trial focused on fertilized anterior cruciate ligament (ACL) reconstruction.
Unlike traditional ACL repairs, fertilized ACL surgery uses a biologic concentrate of the patient’s stem cells, bone marrow and autograft bone along with an internal brace with the goal of stabilizing and expediting the healing process.
“Past patients of the fertilized ACL have already shown shorter recovery times with no known additional risks to the patient,” said Chad D. Lavender, M.D., ...

Combining time-restricted eating with high-intensity functional training may improve body composition and cardiometabolic parameters more than either alone, according to a study published May 1, 2024 in the open-access journal PLOS ONE by Ranya Ameur and Rami Maaloul from the University of Sfax, Tunisia, and colleagues.
Changes in diet and exercise are well-known ways to lose weight and improve cardiometabolic health. However, finding the right combination of lifestyle changes to produce sustainable results can be challenging. Prior studies indicate that time-restricted eating (which limits when, but not what, individuals eat) and ...

Earth System Models – complex computer models which describe Earth processes and how they interact – are critical for predicting future climate change. By simulating the response of our land, oceans and atmosphere to manmade greenhouse gas emissions, these models form the foundation for predictions of future extreme weather and climate event scenarios, including those issued by the UN Intergovernmental Panel on Climate Change (IPCC).
However, climate modellers have long faced a major problem. Because Earth System Models integrate many complicated processes, they cannot immediately run a simulation; they must first ensure that it has reached a stable equilibrium ...
Weather-related power outages in the United States have become nearly twice as common in the last ten years compared to the previous decade. These outages, which can last most of a day, are more than an inconvenience: lack of power and related indoor temperature discomfort can exacerbate health conditions; lack of power also endangers the lives of people who are reliant on electricity-powered medical devices and/or elevators.
A new study led environmental health scientists at Columbia University ...
DURHAM, N.C. -- Duke researchers have opened a new avenue in the attack against influenza viruses by creating a vaccine that encourages the immune system to target a portion of the virus surface that is less variable.
Their approach worked well in experiments with mice and ferrets and may lead to more broadly-protective influenza vaccines and less reliance on an annual shot tailored to that year’s versions of the virus. Even with vaccines, influenza kills about a half-million people each year around the world.
This new vaccine approach, described May 1 in the journal Science Translational ...
