DNMT3B gene variant influences nicotine dependence

December 09, 2017 – Newest research has revealed that a DNMT3B gene variant influences nicotine dependence identified in people of European (Caucasian) descent and African-American decent as well.

Thus, a DNA variant, located in the DNMT3B gene and commonly found in people of European (Caucasian) and African-American descent,

Gene expression and ethnicity: Does it matter?

December 05, 2017 – We are entering the age of precision medicine, in which diagnosis and therapy decisions for each patient will be based on detailed genetic and molecular fingerprints. Unfortunately, much of the revolutionary work that underpins precision medicine has been conducted on populations of European (Caucasian) descent,

Cancer is not like cancer: Ethnic background matters

November 24, 2017 – New research indicates that one-size treatment for one form of blood cancer likely does not fit all, particularly when it comes to ethnic differences of patients.  Thus, African-American men are three times more likely to be diagnosed with multiple myeloma,

Ashkenazi Jewish Women: Little-known Gene Mutations May Boost Breast Cancer Risk

July 27, 2017 – Jewish women of Ashkenazi descent may be at risk for additional genetic mutations that increase their risk of breast cancer, according to a new study just published in JAMA Oncology. Researchers from University of Washington in Seattle found that around 4 percent of Ashkenazi Jewish women without well-known founder mutations in BRCA1 and BRCA2 genes have other mutations that may increase their risk for breast cancer.

  • Genetic tests may differ in their interpretation of certain variants July 1, 2020
    (HealthDay)—Different genetic test interpretations have been identified for genetic variants, and some of these can impact patient management, according to a research letter published online June 30 in the Annals of Internal Medicine.
  • How does our brain fold? Study reveals new genetic insights July 1, 2020
    New research is helping unlock the mystery of how the brain folds as a baby develops in the womb—a process critical to healthy brain function.
  • New infectious disease test accurately diagnoses infection in minutes July 1, 2020
    Melbourne researchers have developed a fast, new test for infections and infectious diseases that could transform Australia's ability to provide targeted clinical care and respond to pandemics and biosecurity threats.
  • Next-generation sequencing to provide precision medicine for rare metabolic disorders June 30, 2020
    An international team of scientists from Switzerland Spain, has studied the genetic basis of aromatase deficiency, a rare metabolic disorder that prevents the production of estrogens in humans, according to new research in JCEM (Journal of Clinical Endocrinology and Metabolism). The latest studies on aromatase deficiency in humans come from the group of Amit V. […]
  • New genomic atlas of the developing human brain June 30, 2020
    For the nascent brain of a human embryo to develop into the complex organ that controls human consciousness, a finely tuned sequence of genetic events has to take place; hundreds of genes are activated and deactivated in a precise symphony. Mutations in these genes disrupt the molecular instruments of the symphony and, if they occur […]
  • Understanding molecular mechanisms of air pollution's impact on ILD critical July 1, 2020
    More research must be done to investigate the role of air pollution on the epigenome in patients with interstitial lung diseases (ILDs), in order to develop strategies that minimize the effects of these pollutants, according to a new article published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
  • Researchers develop computational model to build better capacitors July 1, 2020
    Researchers have developed a computational model that helps users understand how changes in the nanostructure of materials affect their conductivity - with the goal of informing the development of new energy storage devices for a wide range of electronics.
  • Traffic data show drastic changes in Floridians' behavior at onset of the pandemic July 1, 2020
    Using same-day traffic volumes for March 2019 and March 2020 across Florida, researchers examined the relationship of key governmental requests for public isolation and travel limitations. Results show the drastic changes in human behavior during the onset of the pandemic. Traffic volumes by March 22, 2020, dropped by 47.5% compared to that same point in […]
  • A shake-up in cell culturing: Flame sterilization may affect the culture July 1, 2020
    Researchers from the University of Tsukuba have found that flame-sterilizing shake-flasks, to avoid introducing microbial contaminants, considerably increases the carbon dioxide concentration in the flasks. This enhanced carbon dioxide concentration affects the growth of some microbial species, which may affect the quantity of vaccines or other valuable substances produced by the microbes.
  • Lifetime discrimination may increase risk of hypertension among African Americans July 1, 2020
    A study of African Americans in Mississippi shows an association between experiencing discrimination over a lifetime and developing hypertension (also referred to as high blood pressure).African Americans who reported medium and high levels of lifetime discrimination, compared to those who reported low lifetime discrimination, had a higher risk for hypertension.
