Discovery of oral cancer biomarkers could save thousands of lives

April 15, 2019 dna 0
Oral cancer is known for its high mortality rate in developing countries, but an international team of scientists hope its latest discovery will change that. Researchers have discovered epigenetic markers that are distinctly different in oral cancer tissues compared to the adjacent healthy tissues in patients.

Direct-to-Consumer Genetic Testing’s Red Herring: “Genetic Ancestry” and Personalized Medicine.

Front Med (Lausanne). 2019;6:48

Authors: Blell M, Hunter MA

Abstract
The growth in the direct-to-consumer genetic testing industry poses a number of challenges for healthcare practice, among a number of other areas of concern. Several companies providing this service send their customers reports including information variously referred to as genetic ethnicity, genetic heritage, biogeographic ancestry, and genetic ancestry. In this article, we argue that such information should not be used in healthcare consultations or to assess health risks. Far from representing a move toward personalized medicine, use of this information poses risks both to patients as individuals and to racialized ethnic groups because of the way it misrepresents human genetic diversity.

Gum bacteria implicated in Alzheimer’s and other diseases

April 15, 2019 dna 0
Researchers are reporting new findings on how bacteria involved in gum disease can travel throughout the body, exuding toxins connected with Alzheimer’s disease, rheumatoid arthritis and aspiration pneumonia. They detected evidence of the bacteria in brain samples from people with Alzheimer’s and used mice to show that the bacterium can find its way from the mouth to the brain.

Is it genetic code or postal code that influence a child’s life chances?

April 15, 2019 dna 0
Most children inherit both their postal code and their genetic code from their parents. But if genetic factors influence where families are able to live and children’s health and educational success, improving neighborhoods may not be enough. Latest research provides new insights into the highly debated question of whether the neighborhoods that children live in influence their health and life chances.

New DNA ‘shredder’ technique goes beyond CRISPR’s scissors

April 15, 2019 dna 0
An international team has unveiled a new CRISPR-based tool that acts more like a shredder than the usual scissor-like action of CRISPR-Cas9. The new approach, based on Type I CRISPR-Cas3, is able to wipe out long stretches of DNA in human cells with programmable targeting, and has been shown to work in human cells for the first time.
