Researchers identify two FDA approved drugs that may fight HIV
Researchers at the University of Minnesota Academic Health Center have identified two drugs that, when combined, may serve as an effective treatment for HIV.
Study links microRNA to shut-down of DNA-repair genes
New research shows for the first time that molecules called microRNA can silence genes that protect the genome from cancer-causing mutations.
Stem-cell activators switch function, repress mature cells
In a developing animal, stem cells proliferate and differentiate to form the organs needed for life. A new study shows how a crucial step in this process happens and how a reversal of that step contributes to cancer.
Molecule plays early role in nonsmoking lung cancer
The cause of lung cancer in never-smokers is poorly understood, but a study led by investigators at the Ohio State University Comprehensive Cancer Center and at the National Cancer Institute has identified a molecule believed ...
Scientists Find Rare, Potent Antibody to HIV-1

HIV virulence depends on where virus inserts itself in host DNA
The human immunodeficiency virus (HIV) can insert itself at different locations in the DNA of its human host - and this specific integration site determines how quickly the disease progresses, report researchers ...
Genetic mutation linked to lethal disease
Researchers have identified a genetic mutation found in the Ohio Amish population as the cause of a fatal developmental disease in fetuses and infants, according to research published in the April 8, 2011, issue of Science.
Study provides molecular rationale for combining targeted agents to treat breast cancer
A new study by Ohio State University cancer researchers provides a rational for treating breast cancer by combining two kinds of targeted agents, one that inhibits an overactive, cancer-causing pathway in cancer cells and ...
Damaging inflammatory response could hinder spinal cord repair
(PhysOrg.com) -- The inflammatory response following a spinal cord injury appears to be set up to cause extra tissue damage instead of promoting healing, new research suggests.

Childhood abuse, adversity may shorten life, weaken immune response among the elderly
The emotional pains we suffer in childhood can lead to weakened immune systems later in life, according to a new study.
Protein handlers should be effective treatment target for cancer and Alzheimer's
Cancer and Alzheimer's have excess protein in common and scientists say learning more about how proteins are made and eliminated will lead to better treatment for both.
