Scientists Found a Gene that May Protect Against Heart Disease

A team of scientists from the University of California identified a gene that may play role in preventing heart disease. The gene, called MeXis, acts within key cells inside clogged arteries to help remove redundant cholesterol from blood cells.gene to prevent heart disease

The gene MeXis was considered as “unhelpful” gene because it was presumed that it had no function as it didn’t make any protein. Nevertheless, the recent studies suggested that the genes of this type can perform important biological functions without making proteins. Instead, they are producing a special class of molecules, long non-coding RNAs (lncRNAs).

Senior author of the study Dr. Peter Tontonoz, the Frances and Albert Piansky Professor of Pathology and Laboratory Medicine at the David Geffen School of Medicine at UCLA, says: “What this study tells us is that lncRNAs are important for the inner workings of cells involved in the development of heart disease. Considering many genes like MeXis have completely unknown functions, our study suggests that further exploring how other long non-coding RNAs act will lead to exciting insights into both normal physiology and disease.”

Childhood Experiences Can Change Your DNA for the Rest of Life

A new research from Northwestern University, USA, suggests that experiences in childhood can influence DNA and alter it for the rest of human’s life.Childhood Experiences

A team of researchers analyzed over hundred genes associated with inflammation, looking for hints of epigenetic changes, changes that can be influenced by everything we do from how we sleep to how wealthy we are.

One of the more prominent forms of these epigenetic processes is methylation, one of nine of those genes was found to have a close relationship with a number of childhood variables including household socioeconomic status in childhood, extended absence of a parent in childhood, and even whether the person was born in the dry season.

In the future, this study could help explain the prevalence of cardiovascular and certain inflammatory diseases in specific communities.
