Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Scribble protein found to be an important regulator of breast cancer

In breast tissue, cells lining the breast's ducts have a certain shape that is required to maintain both organ structure and function.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Maas Biolab scientists validate cyclosporin human neuroprotection

Maas Biolab researchers CSO Eskil Elmer, M.D., Ph.D. and neuroscientist Magnus Hansson, M.D., Ph.D., and colleagues have for the first time ever demonstrated the mitochondrial permeability transition (mPT) or "megapore" occurs in viable adult human neuron mitochondria and the ability of cyclosporin-A to block its formation.

PEA-15 protein points to potential targeted approach for ovarian cancer

A protein known to inhibit the growth of ovarian cancer works in part by forcing cancer cells to eat themselves until they die, researchers at The University of Texas M. D. Anderson Cancer Center report in the Nov. 15 issue of Cancer Research .

Difluoromethylornithine may affect Barrett's esophagus

"While there was a suggestion that difluoromethylornithine (DFMO) may influence the extent of Barrett's dysplasia, this finding is very preliminary and further study of this agent in a larger number of patients is needed," said Frank A. Sinicrope, M.D., professor of medicine and oncology at the Mayo Clinic, Rochester, MN.

Isoflurane induces Alzheimer's-associated changes in mouse brains

For the first time researchers have shown that a commonly used anesthetic can produce changes associated with Alzheimer's disease in the brains of living mammals, confirming previous laboratory studies.

Does HBV infection induce acute cellular DNA damage?

Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA.

Santaris Pharma releases positive data on LNA-based survivin inhibitor

Santaris Pharma announced today that SPC3042, a RNA-based antisense oligonucleotide developed using the company's proprietary Locked Nucleic Acid (LNA) technology, potently blocks survivin, a key survival protein in cancer cells, in both in vitro and in vivo models of prostate cancer. Importantly, SPC3042 works synergistically with the anticancer drug paclitaxel (Taxol) in both model systems.

Calcitriol - active form of vitamin D - may protect us from radiation

Radiological health expert Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene suggests that a form of vitamin D could be one of our body's main protections against damage from low levels of radiation.

Sunesis Pharmaceuticals presents data of Voreloxin in patients with acute myeloid leukemia and ovarian cancer

Sunesis Pharmaceuticals, Inc. presented data from three clinical trials of the company's lead drug candidate, voreloxin (formerly SNS-595), at the Chemotherapy Foundation Symposium held in New York on November 4-8.

Genes that control cell death may play role in age-related hearing loss

Several genes that play a role in how our body's cells normally auto-destruct may play a role in age-related hearing loss, according to research published online in the journal Apoptosis - a journal devoted to the topic of cell suicide, or programmed cell death.

White wine as healthy for the heart as red

A new study will provide comfort to white wine lovers and give them a good excuse to pour themselves a glass of Sauvignon blanc because it now appears that white wine is just as healthy for the heart as red.

Quark Pharmaceuticals' siRNAs examined alone and in xombination with chemotherapy

Quark Pharmaceuticals, Inc. has announced that the journal Cancer Research published results on efficacy of siRNA targeting its proprietary target gene against non-small cell lung cancer (NSCLC) in the edition dated October 1, 2008.

Existing anti-obesity drugs may be effective against flu, hepatitis and HIV

Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection, according to a study published today in the journal Nature Biotechnology.

Multifunctional polymer nanoparticles pass critical in vivo test

In an effort to overcome the drug resistance that often occurs in cancer, a team of investigators has developed a nanoparticle made of a blend of polymers that first releases a powerful anticancer drug and then delivers an agent that tricks a drug-resistant cell into committing suicide. Now, tests in mice with human breast cancer have shown that these blended nanoparticles are effective in maintaining high levels of both drugs in the vicinity of tumors.

Study identifies immune response that enables TB bacteria to multiply, provides new target for TB drugs

Researchers have identified an immune system response to tuberculosis that enables TB bacteria to spread through the lungs, providing a new target for TB drug development, according to a study published Sunday in Nature Immunology, AFP/Washington Times reports.

Unsuccessful drug against anxiety opens a novel gateway for the treatment of cancer

According a new study, unsatisfying drug for anxiety reveals scientists a promising novel anti-cancer drug target.

Oxidative stress: mechanism of cell death clarified

Dr. Marcus Conrad of the Institute of Clinical Molecular Biology and Tumor Genetics at the Helmholtz Zentrum Munchen has decrypted the molecular mechanism through which the death of cells is caused by oxidative stress.

Issues on cholesterol: diet, statins and genetics

Genetic lipoprotein disorders are frequently seen in patients with premature coronary artery disease (CAD). An example of strong genetic predisposition is the disorder: familial hypercholesterolemia, where a single gene defect (the low density lipoprotein receptor) contributes to most of the familial expression of CAD.

Berries show to have a genome-wide effect on the expression of genes involved in cancer development

New research strongly suggests that a mix of preventative agents, such as those found in concentrated black raspberries, may more effectively inhibit cancer development than single agents aimed at shutting down a particular gene.
