The DNA molecule is not naked in the nucleus. Instead, it is folded in a very organized way by the help of different proteins to establish a unique spatial organization of the genetic information. This 3D spatial genome organization is fundamental for the regulation of our genes and has to be established de novo by each individual during early embryogenesis. Researchers now reveal a yet unknown and critical role of the protein HP1a in the 3D genome re-organization after fertilization. The study identifies HP1a as an epigenetic regulator that is involved in establishing the global structure of the genome in the early Drosophila embryo.
Researchers have published an in-depth look at the SARS-CoV-2 mutations that have taken place during the past year. The review discusses the findings of over 180 research articles and follows the changes that have taken place in the SARS-CoV-2 genome, and the variants that have occurred as a result.
Good dental health may help prevent heart infection from mouth bacteria
Good oral hygiene and regular dental care are the most important ways to reduce risk of a heart infection called infective endocarditis caused by bacteria in the mouth. There are four categories of heart patients considered to be at highest risk for adverse outcomes from infective endocarditis, and only these patients are recommended to receive preventive antibiotic treatment prior to invasive dental procedures.
Airports Step Up Mental Health Assistance as Passenger Anxiety Soars
As more people return to air travel, tension is mounting in airports nationwide. Atlanta’s Hartsfield-Jackson is among those that have responded to the pandemic-related stress and fear among passengers and employees by offering services such as meditation, chaplains and other help in their terminals.
