Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

'Survival protein' protects brain against effects of stroke

Johns Hopkins scientists say that a newly discovered "survival protein" protects the brain against the effects of stroke in rodent brain tissue by interfering with a particular kind of cell death that's also implicated in complications from diabetes and heart attack.

Triptolide isolated from Chinese medicinal plant blocks gene control machinery in cells

Researchers at the Johns Hopkins School of Medicine have discovered that a natural product isolated from a traditional Chinese medicinal plant commonly known as thunder god vine, or lei gong teng, and used for hundreds of years to treat many conditions including rheumatoid arthritis works by blocking gene control machinery in the cell. The report, published as a cover story of the March issue of Nature Chemical Biology, suggests that the natural product could be a starting point for developing new anticancer drugs.

New research may shed light on how HIV virus reactivates from latency

New research enhances the current knowledge of how human immunodeficiency virus type-1, which causes AIDS, controls the cell cycle of cells that it infects. The new findings may shed light on how the virus reactivates after entering a dormant state, called latency.

Realignment with participants' interest important for future of genomic research

Obtaining consent for genetic studies can be an opportunity for researchers to foster respectful engagement with participants, not merely to mitigate legal risk. This shift is proposed in a policy forum appearing tomorrow, Jan. 21, in Science, the journal of the American Academy for the Advancement of Science.

An ubiquitin-specific peptidase that potentially promote cancer cell necrosis

"ubiquitin-specific peptidase 21 (USP21) has been identified as another essential player in regulation of tumor necrosis factor alpha (TNF-alpha)-induced nuclear factor kappaB (NF-kappaB) activation by working on receptor-interacting protein 1(RIP1)."

EMBL scientists identify genes involved in human cell division

Name a human gene, and you'll find a movie online showing you what happens to cells when it is switched off. This is the resource that researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and their collaborators in the Mitocheck consortium are making freely available, as the result of a study in which they have identified the genes involved in mitosis - the most common form of cell division - in humans.

Study shows cellular circuitry is more complex than previously thought

Using an elaborate sleuthing system they developed to probe how cells manage their own division, Johns Hopkins scientists have discovered that common but hard-to-see sugar switches are partly in control.

Dramatically enhanced image contrast could revolutionize diagnostics and therapeutics

A Northwestern University study shows that coupling a magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and thus vivid image contrast.

New drug might make tumor cells more sensitive to therapy

Scientists at St. Jude Children's Research Hospital have shown that it might be possible to make tumor cells more sensitive to irradiation and some types of chemotherapy by treating them with a drug that cripples their ability to repair DNA damage caused by these therapies.

New understanding of how the DNA helix replicates

A team of researchers led by University of Virginia Health System geneticists has uncovered a major secret in the mystery of how the DNA helix replicates itself time after time.

Noninvasive treatment of cancer tumors

Ram Devireddy, assistant professor of mechanical engineering at LSU, recently co-authored an article with Todd Monroe, assistant professor of biological and agricultural engineering, investigating the complex effects of nanoparticles on cell freezing.

Nanoscale "egg" to deliver platinum to tumor cells

Researchers at the Hong Kong University of Science and Technology have developed a nanoscale "egg" that could safely deliver platinum, a known anticancer agent, to tumor cells.

Unsuspected protein CD147, regulates the production of plaque-forming peptides that are the defining feature of Alzheimer's

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory have discovered an unsuspected subunit of the protein complex gamma-secretase, which plays a central role in Alzheimer's disease.
