Identify genetic markers to predict male fertility
The diagnosis of male fertility is usually performed through the observation of the sperm in the microscope. However, a normal quality semen does not guarantee an adequate fertility. In fact, there is a considerable proportion of cases of unexplained infertility and data suggest that abnormal sperm function may have a genetic or molecular origin. (2012-05-24)

Stem cell research paves way for progress on dealing with Fragile X retardation
Researchers at the Hebrew University of Jerusalem have achieved, for the first time, the generation of neuronal cells from stem cells of Fragile X patients. (2012-05-23)

Scientists unravel role of fusion gene in prostate cancer
Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein -- but no one has known how that alteration promotes cancer growth. (2012-05-23)

Researchers reveal an RNA modification influences thousands of genes
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. (2012-05-18)

New technique reveals unseen information in DNA code
Imagine reading an entire book, but then realizing that your glasses did not allow you to distinguish "g" from "q." What details did you miss? (2012-05-18)

Protein RAL associated with aggressive characteristics in prostate, bladder and skin cancers
We have known for years that when the proteins RalA and RalB are present, cells in dishes copy toward aggressive forms of cancer. (2012-05-18)

Researchers identify key genes and prototype predictive test for schizophrenia
An Indiana University-led research team, along with a group of national and international collaborators, has identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease.

A marker in the lining of the lungs could be useful diagnostic technique for lung cancer screening
The most recent research released in June's Journal of Thoracic Oncology says molecular biomarkers in the tissue and fluid lining the lungs might be an additional predictive technique for lung cancer screening. (2012-05-16)

Discovery of plant proteins may boost agricultural yields and biofuel production
Scientists at the Salk Institute for Biological Studies and Iowa State University discovered a family of plant proteins that play a role in the production of seed oils, substances important for animal and human nutrition, biorenewable chemicals and biofuels. (2012-05-15)

Genetic test identifies eye cancer tumors likely to spread
Researchers at Washington University School of Medicine in St. Louis have developed a genetic test that can accurately predict whether the most common form of eye cancer will spread to other parts of the body, particularly the liver. (2012-05-15)
