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).

De novo somatic gene mutations likely to cause hemimegalencephaly

Hemimegalencephaly is a rare but dramatic condition in which the brain grows asymmetrically, with one hemisphere becoming massively enlarged. Though frequently diagnosed in children with severe epilepsy, the cause of hemimegalencephaly is unknown and current treatment is radical: surgical removal of some or all of the diseased half of the brain.

Smoking of fathers before conception can damage genetic information of their offspring

As you decide what to get dad for Father's Day, you might want to consider what he gave you when you were conceived. If he smoked, your genes are likely damaged, and your odds for cancers and other diseases throughout your life could be increased. A new research report appearing online in the FASEB Journal, scientists show for the first time in humans that men who smoke before conception can damage the genetic information of their offspring.

WCMC researchers devise innovative boxer-like strategy to fight multiple myeloma

Weill Cornell Medical College researchers have devised an innovative boxer-like strategy, based on the serial use of two anti-cancer drugs, to deliver a one-two punch to first weaken the defenses of multiple myeloma and then deliver the final knock-out punch to win the fight.

Gene expression and peripheral blood as tools for pinpointing genes linked to autism

UCLA researchers have combined two tools - gene expression and the use of peripheral blood -- to expand scientists' arsenal of methods for pinpointing genes that play a role in autism. Published in the June 21 online edition of the American Journal of Human Genetics, the findings could help scientists zero in on genes that offer future therapeutic targets for the disorder.

Faulty conclusions due to contamination, misidentification and redundancy in widely available cell lines

Modern cancer therapies start in cells - researchers compare cancer samples to healthy cells to discover how cancer is genetically different, and use cell lines to test promising new drugs. However, a University of Colorado Cancer Center study published this week in the journal Gynecologic Oncology shows that due to a high rate of contamination, misidentification and redundancy in widely available cell lines, researchers may be drawing faulty conclusions.

Study links two specific strains of bacteria with indoor mold from water damage

Bacterial contamination in water-damaged buildings has been identified as a potential cause of health problems, including infection and respiratory conditions like asthma. Which specific bacteria contribute to these problems, however, has been unknown-making it difficult for public health officials to develop tools to effectively address the underlying source of the problem.

Researchers determine structure of MRN complex

Double-stranded breaks in cellular DNA can trigger tumorigenesis. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have now determined the structure of a protein involved in the repair and signaling of DNA double-strand breaks. The work throws new light on the origins of neurodegenerative diseases and certain tumor types.
