Genetic Discovery Will Revolutionize Understanding Of Gene Expression

May 19, 2012
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics that DNA consists of only four bases. Now, researchers at Weill Cornell Medical ...

Gene Expression By Ultraviolet

May 13, 2012
Imagine being able to control genetic expression by flipping a light switch. Researchers at North Carolina State University are using light-activated molecules to turn gene expression on and off. Their method enables greater precision when studying gene function, and could lead to targeted therapies for diseases like cancer. Triplex-forming oligonucleotides ...

Improving Hormone-Receptor-Positive Breast Cancer Management Through Progesterone Receptor Expression Measurement

May 7, 2012
American and Spanish researchers have found potential ways for doctors to improve the treatment of hormone receptor-positive breast cancer even if they lack access to costly multi-gene tests, as they reported at the 4th IMPAKT Breast Cancer Conference. Because breast cancer is a biologically and clinically varied disease, doctors aim ...

Gene expression reveals how potatoes are cultivated

May 3, 2012
Organically grown potatoes have a higher gene expression of starch production than conventional ones. This statement is put forward by RIKILT, part of Wageningen UR, researcher Jeroen van Dijk, who can tell organically grown potatoes from conventional ones by measuring the RNA in the plant cells. But he cannot say ...

Shorter sleep provides more permissive environment for expression of obesity related genes

May 2, 2012
Toss out another old wives' tale: Sleeping too much does not make you fat. Quite the opposite, according to a new study examining sleep and body mass index (BMI) in twins, which found that sleeping more than nine hours a night may actually suppress genetic influences on body weight.

Control of gene expression: Histone occupancy in your genome

May 1, 2012
When stretched out, the genome of a single human cell can reach six feet. To package it all into a tiny nucleus, the DNA strand is tightly wrapped around a core of histone proteins in repeating units—each unit known as a nucleosome. To allow access for the gene expression machinery ...

Preeclampsia May Be Explained By Changes In Gene Expression During Pregnancy

April 16, 2012
Virginia Commonwealth University School of Medicine researchers have discovered that changes in the gene expression of a key enzyme may contribute to high blood pressure and increase susceptibility to forming blood clots in pregnant women with preeclampsia. These findings could provide clues to the best treatment approaches for high blood ...
