DNA News and Research

RSS

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Researchers discover potential way to stop tumor growth

Washington State University researchers have discovered a way to help cancer cells age and die, creating a promising avenue for slowing and even stopping the growth of tumors. "Hopefully, we can make cancer cells die like normal cells," says Weihang Chai, an assistant professor in the WSU School of Molecular Biosciences and WWAMI medical education program in Spokane. "Basically, you make the cancer cell go from immortal to mortal."

Restricted diet can extend lifespan: Study

New research being presented this week is giving scientists new insight into why a restricted diet can lead to a longer lifespan and reduced incidence of age-related diseases for a wide variety of animals. Scientists have known for some time that a restricted diet can extend the lifespan of certain animals but this work shows how it affects ageing mechanisms - and significantly has also shown that the effects occur even if the restricted diet is adopted later in life.

DNA copying error in autism sufferers discovered

Rubicon winner Dalila Pinto discovered a copying error in the DNA of trial subjects who suffered from autism or a similar condition. Some segments of their DNA were copied either once too often or missed out of the copying process. This is a highly promising result from the world's largest investigation into autism. The top journal Nature placed the results online on 9 June.

Essential nutrient in eggs may reduce risk of infant heart defects

A study published in the American Journal of Clinical Nutrition found that a choline-deficient diet is associated with increased risk for heart defects during prenatal development. Choline is an essential nutrient required for normal cell activity, healthy brain and nerve function, liver metabolism and transportation of nutrients throughout the body.

Smokers exposed to wood smoke are at increased risk of COPD: Research

Smokers who are exposed to wood smoke, either through home heating and cooking or through ambient neighborhood pollution, are not only at increased risk of COPD, but are also more likely to have epigenetic changes in the DNA that further increase their risk of COPD and related pulmonary problems.

Study suggests chronic kidney disease affects persons of African, Hispanic heritage at higher rate

Chronic kidney disease affects millions in North America, with persons of African heritage being at a four-fold higher risk and those of Hispanic heritage having a two-fold higher risk compared to the rest of the population. An international study carried out by Dr. Karl Skorecki, from the Technion-Israel Institute of Technology and Rambam Medical Center in Haifa, and his team points to the APOL1 gene as involved in the increased risk of kidney disease in this high-risk population. The results are to be published online in Springer's journal Human Genetics.

Report on new, automated genetic method for determining blood types appears in Analytical Chemistry

Scientists are reporting an advance toward enabling more blood banks to adopt so-called "extended blood group typing," which increases transfusion safety by better matching donors and recipients. Their report on a new, automated genetic method for determining a broader range of blood types appears in ACS' Analytical Chemistry, a semi-monthly journal.

Key protein in insulin signaling pathway adds insights into development, aging

What makes a bee grow up to be a queen? Scientists have long pondered this mystery. Now, researchers in the School of Life Sciences at Arizona State University have fit a new piece into the puzzle of bee development. Their work not only adds to understanding about bees, but also adds insights into our own development and aging.

Keck School of Medicine receives grant for research on biomarker impact on breast cancer screening

Researchers at the Keck School of Medicine of the University of Southern California (USC) will test whether a set of blood-based biomarkers can assist mammography in the early detection of breast cancer with a $180,000 grant announced today from Susan G. Komen for the Cure®. The grant will fund research into whether specific biomarkers, or minute substances in the blood, can effectively distinguish breast cancer patients from their healthy counterparts and whether an inexpensive, less invasive screening strategy can be developed based on this approach.
