Les en-têtes de football pourraient être plus risqués pour les porteurs du génotype APOE4

02 février 2020 – Les en-têtes de football pourraient être plus risqués pour les porteurs du génotype APOE4 – c’est le titre d’un récent article de Reuters Health dans Medscape. Par conséquent, les joueurs de football avec le génotype de l’apolipoprotéine E4 (APOE4) devraient être en mesure de limiter le nombre d’en-têtes,

Les individus de peau foncée aux cheveux blonds naturels – En génétique, tout est possible

8 août 2019 – Les cheveux blonds sont un phénotype humain plutôt rare, présent presque exclusivement en Europe et en Océanie. La pigmentation humaine varie considérablement au sein des populations et entre les populations et dépend de l’exposition aux rayons ultraviolets (UV) ainsi que du type et de la quantité de mélanine produit dans les mélanocytes et les kératinocytes.

Aspects génétiques de la globésité: Glocalisés oui ou non?

juin 26, 2019 – L’épidémie mondiale d’obésité est si importante qu’elle a maintenant un nom prépondérant: la globésité (qui découle évidemment de l’obésité globale). Des questions très intéressantes se posent dans ce contexte, à savoir s’il existe des facteurs glocalisés (globaux ou locaux) impliqués dans cette épidémie.

  • New type of taste cell discovered in taste buds août 13, 2020
    Our mouths may be home to a newly discovered set of multi-tasking taste cells that—unlike most known taste cells, which detect individual tastes—are capable of detecting sour, sweet, bitter and umami stimuli. A research team led by Kathryn Medler at the University at Buffalo reports this discovery in a study published 13th August in PLOS […]
  • Researchers discover genetic link to predict positive response to immunotherapy in patient août 13, 2020
    A Singapore team led by clinician-scientists and researchers from the National Cancer Centre Singapore (NCCS) discovered a genetic link to better predict treatment response for relapsed/refractory patients with natural-killer T-cell lymphoma (NKTCL), a highly aggressive form of blood cancer. The team performed whole-genome sequencing, to identify mutation in PD-L1 gene as a reliable biomarker to […]
  • Evolution and everyday stress have led to disproportionate suffering among women août 13, 2020
    We're 100% behind knowledge-based research, but sometimes you really do have to question evolution!
  • A cancer mystery more than 40 years old is solved thanks to epigenetics août 12, 2020
    Before the first oncogene mutations were discovered in human cancer in the early 1980s, the 1970s provided the first data suggesting alterations in the genetic material of tumors. In this context, the prestigious journal Nature published in 1975 the existence of a specific alteration in the transformed cell: an RNA responsible for carrying an amino […]
  • Combining genetic information with EMRs to pinpoint childhood epilepsies août 11, 2020
    A team of researchers at Children's Hospital of Philadelphia (CHOP) affiliated with the CHOP Epilepsy Neurogenetics Initiative (ENGIN) further bridged the gap between genomic information and clinical outcome data by systematically linking genetic information with electronic medical records, focusing on how genetic neurological disorders in children develop over time. The findings were published today in […]
  • Employers reject transgender people août 13, 2020
    Employers in Sweden more often reject job applications from transgender people -- especially in male-dominated occupations. Moreover, transgender people face discrimination from two different grounds for discrimination. This is according to a study from Linköping University that was recently published in the journal Labour Economics.
  • How a protein stops cells from attacking their own DNA août 13, 2020
    Scientists at EPFL have demonstrated the mechanism that allows cells to fight off viral DNA without triggering an immune response against their own genetic material.
  • Global deaths due to smokeless tobacco are up by a third, according to new study août 13, 2020
    The number of deaths globally due to smokeless tobacco has gone up by a third in 7 years to an estimated 350,000 people, a new study suggests.
  • A watershed moment for US water quality août 13, 2020
    A new federal rule that determines how the Clean Water Act is implemented leaves millions of miles of streams and acres of wetlands unprotected based on selective interpretation of case law and a distortion of scientific evidence, researchers say in a new publication.
  • Study: Medical marijuana associated with fewer hospitalizations for individuals with SCD août 13, 2020
    Individuals with sickle cell disease (SCD) who receive medical marijuana to treat pain may require fewer visits to the hospital, according to a new study in Blood Advances. Adults with SCD who requested and obtained medical marijuana were admitted to the hospital less frequently than those who did not obtain it.
