Human cytomegalovirus mimics human protein to hijack cell division machinery

Viruses are masters of deception, duping their host's cells into helping them grow and spread. A new study has found that human cytomegalovirus (HCMV) can mimic a common regulatory protein to hijack normal cell growth machinery, disrupting a cell's primary anti-cancer mechanism.

Study finds darapladib lowers biomarker for cardiovascular problems

Despite widespread use of cholesterol-lowering drugs, a significant number of cardiac patients continue to suffer heart attacks and stroke. Researchers theorize that high levels of an enzyme found in coronary plaques may be to blame, by making plaques more likely to rupture and block blood flow. The drug darapladib may offer a way to fight that risk, according to new research led by the University of Pennsylvania School of Medicine.

Study shows prostate cancer gene 3 (PCA3) correlates with severity of prostate cancer

A study published in the May 2008 issue of the peer-reviewed Journal of Urology demonstrates that the prostate cancer gene 3 (PCA3) can be used to detect and stratify stage and grade of prostate cancer.

Shift in HIV prevention priorities needed - reducing multiple sexual partnerships and providing male circumcision services should be emphasized

According to a new policy analysis led by researchers at the Harvard School of Public Health (HSPH) and the University of California, Berkeley, the most common HIV prevention strategies-condom promotion, HIV testing, treatment of other sexually transmitted infections (STIs), vaccine and microbicide research, and abstinence-are having a limited impact on the predominantly heterosexual epidemics found in Africa.

Scientist discovers mechanism that 'silences' unmatched genes during cellular reproduction

When most people discover mold on their bread, they immediately throw it out. Others see a world of possibilities in the tiny fungus. A University of Missouri scientist, along with a collaborative research team, has examined a new mechanism in the reproductive cycle of a certain species of mold.

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature

Hopkins researchers discover new link to schizophrenia

Neuroscientists at Johns Hopkins have discovered that mice lacking an enzyme that contributes to Alzheimer disease exhibit a number of schizophrenia-like behaviors. The finding raises the possibility that this enzyme may participate in the development of schizophrenia and related psychiatric disorders and therefore may provide a new target for developing therapies.

New key mechanism in cell division discovered

Scientists at the IFOM-IEO Campus have revealed the function of a protein that is indispensable for passing on an accurate copy of the genome from mother to daughter cells. This study, published in Cell, opens up new avenues of research to reduce the toxicity of chemotherapy in the treatment of cancer.
