Can periodontal disease act as a risk factor for HIV-1?
Today, during the 87th General Session of the International Association for Dental Research, convening at the Miami Beach Convention Center, a group of scientists from Nihon University (Tokyo, Japan) will present findings suggesting that periodontal disease could act as a risk factor for reactivating latent HIV-1 in affected individuals. view more (2009-04-03)
Umbilical cord gene expression signals premature babies' lung disease risk
Diagnosing a risk of fatal lung disorders may be possible by analysing the umbilical cords of premature babies, according to research published in the online open access journal Genome Biology. view more (2007-10-04)
Progress in understanding the malarial parasite
About 2 million people die of malaria every year, of which more than a million are children in sub-Saharan Africa. Malaria is caused by a protozoan parasite belonging to the genus Plasmodium, and Plasmodium falciparum is responsible for the most severe form of malaria. view more (2007-09-14)
DFG Establishes 14 New Research Units: new areas of research at universities
The Grants Committee on General Research Funding of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has resolved to establish 14 new Research Units. In these Research Units scientists and academics work on special scientific questions in an interdisciplinary and interregional manner. With the funding in this programme, which... view more...

Gene-chip studies provide new leads in treating lung disease of premature newborns
Some 20 to 40 percent of extremely premature infants suffer abnormal lung development leading to bronchopulmonary dysplasia, a chronic lung disease that can cause long-term breathing problems. view more (2007-10-04)
Promising cell protein may play role in infection and dry eye
Plasminogen Activator Inhibitor Type 2 (PAI-2), a protein found in various cell types including the skin, has been discovered in the tissue covering the eye and may have future clinical implications in various pathologies of the ocular surface such as eye infection or dry eye. view more (2006-05-17)
"Sloppy Genes" Behave Like Their Neighbours: New Findings Reveal That The Regulation Of Gene Expression Is Much Less Strictly Controlled Than Was Previously Thought
The inaugural issue of Journal of Biology features groundbreaking research that challenges the traditional view of how genes are controlled. Our current understanding of gene expression, the fundamental process by which proteins are made from the instructions encoded in DNA, is that the process is tightly controlled so that the correct amount of... view more...

Cocaine-linked genes enhance behavioral effects of addiction
New research sheds light on how cocaine regulates gene expression in a crucial reward region of the brain to elicit long-lasting changes in behavior. view more (2009-05-14)
Epigenetics to shape stem cell future
Everyone hopes that one day stem cell-based regenerative medicine will help repair diseased tissue. view more (2007-02-20)
UD leads $5.3-million research project on rice epigenetics
Using a novel "deep sequencing" technology that can in one fell swoop decode 50 million sequences representing well over a billion bases of DNA, a research team led by University of Delaware scientists is working to unmask where, why and how certain genes are switched on or off in rice--a crop vital to the world's food supply. view more (2007-09-11)
Gladstone scientists identify key factors in heart cell creation
Scientists at the Gladstone Institute of Cardiovascular Disease have identified for the first time key genetic factors that drive the process of generating new heart cells. view more (2009-04-27)
Cancer is a stem cell issue
There is an urgent reason to study stem cells: stem cells are at the heart of some, if not all, cancers. view more (2007-02-20)
How body size is regulated: International study discovers ten new genes related to human growth
Scientists are beginning to unravel the question why people distinctly vary in size. view more (2008-05-12)
Gene-regulating enzyme is also a target for anti-depressive drugs
In 2005, professor Ramin Shiekhattar, Ph.D., at The Wistar Institute and his colleagues reported details about an enzyme involved in appropriately repressing sets of neuronal genes in non-neuronal cells. view more (2006-06-26)
Study shows that genetic quality of sperm deteriorates as men age
New research indicates that the genetic quality of sperm worsens as men get older, increasing a man's risk of being infertile, fathering unsuccessful pregnancies and passing along dwarfism and possibly other genetic diseases to his children. view more (2006-06-06)
Researchers identify protein-telomere interactions that could be key in treating cancer
A team of researchers from The Wistar Institute have shown that a large non-coding RNA in mammals and yeast plays a central role in helping maintain telomeres, the tips of chromosomes that contain important genetic information and help regulate cell division. view more (2009-09-01)
Tolerance to inhalants may be caused by changes in gene expression
Changes in the expression of genes may be the reason why people who abuse inhalants, such as spray paint or glue, quickly develop a tolerance, biologists at The University of Texas at Austin have discovered. view more (2007-10-18)
USC researchers identify DNA mutation that occurs at beginning point of T-cell lymphoma
Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a key mechanism that causes chromosomes within blood cells to break-an occurrence that marks the first step in the development of human lymphoma. view more (2009-06-12)
Large DNA stretches, not single genes, shut off as cells mature
Experiments at Johns Hopkins have found that the gradual maturing of embryonic cells into cells as varied as brain, liver and immune system cells is apparently due to the shut off of several genes at once rather than in individual smatterings as previous studies have implied. view more (2009-01-20)
Farnesoid X receptor regulates cystathionase
The expression and activity of Cystathionase is reduced in rodent models of liver injury, leading to hyper-homocysteinemia and impaired generation of hydrogen sulphide, two factors that contribute to endothelial dysfunction and increased intrahepatic resistance. view more (2009-05-13)
