Study: Harmless virus kills some cancers
Six days is all it takes for a common, non-disease-causing virus to kill cervical, breast, prostate and squamous cell cancer cells in laboratory cultures, according to Penn State College of Medicine researchers. view more (2005-06-22)
Selective marker found to indicate aggressive form of breast cancer
Researchers have linked a structural protein called nestin to a particularly deadly form of breast cancer, identifying a new biomarker that could lead to earlier detection and better treatment. view more (2007-01-15)
Helicobacter pylori - the key behind its recognition is somewhere else
The first step against infection is the detection of microorganisms capable of causing disease. This is done through the recognition of molecular structures not shared by the host, but also present in other harmless or even useful microbes. A question that has puzzled scientists for many years is how the host knows exactly against which microbes... view more... (2004-10-29)
Gains in the fight against acid aspiration lung injury
Doctors are gaining new leverage in the fight against lung injury caused by acid reflux. The paper by Bonnans et al., "Lipoxin A4 regulates bronchial epithelial cell responses to acid injury," appears in the April issue of The American Journal of Pathology and is accompanied by a commentary. view more (2006-05-03)
Lung cancer cells activate inflammation to induce metastasis
A research team from the University of California, San Diego School of Medicine has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells. view more (2009-01-05)
Inflammation contributes to colon cancer
Researchers led by Drs. Lillian Maggio-Price and Brian Iritani at The University of Washington found that mice that lack the immune inhibitory molecule Smad3 are acutely sensitive to both bacterially-induced inflammation and cancer. They report these findings in the January 2009 issue of The American Journal of Pathology. view more (2009-01-22)
Researchers identify molecular basis of inflammatory bowel disease
Inflammatory bowel diseases, such as Crohn's disease and Ulcerative Colitis, severely impair the lives of more than four million people worldwide. The development of effective therapies against these diseases requires an understanding of their underlying molecular mechanisms. Researchers from the Universities of Cologne and Mainz in Germany, the... view more... (2007-03-15)
Discarded placentas deliver researchers promising cells similar to embryonic stem cells
Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells. view more (2005-08-08)
Research details how a virus hijacks cell signals to cause infection
A common virus that causes meningitis and heart inflammation takes a "back door" approach to evade natural barriers, then exploits biological signals to infect human cells. view more (2006-01-13)
Stem cells provide clues to cancer spread
Scientists have made a breakthrough in understanding how cancers spread in what could lead to new ways of beating the disease. view more (2007-05-23)
Protein maintains cross talk between cells that control hair growth
Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University and the Howard Hughes Institute have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose unique collection of proteins ultimately instruct... view more...

Cellular pathway yields potential new weapon in vaccine arsenal
When a cell has to destroy any of its organelles or protein aggregates, it envelopes them in a membrane, forming an autophagosome, and then moves them to another compartment, the lysosome, for digestion. Two years ago, Rockefeller University assistant professor Christian Münz showed that this process, called autophagy, sensitizes cells for... view more... (2006-12-27)
New developments in biomarkers for epithelial ovarian cancer
With the genomic revolution radical improvement has been made in methods of detection of ovarian cancer. view more (2007-11-30)
Two-faced protein can stop metastasis or promote it, researchers say
A protein known to be a key component of the glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found. view more (2006-09-19)
Eye cells believed to be retinal stem cells are misidentified
Cells isolated from the eye that many scientists believed were retinal stem cells are, in fact, normal adult cells, investigators at St. Jude Children's Research Hospital have found. view more (2009-03-31)
Researchers writing story of the 'alcoholic lung'
Chronic alcohol abuse disrupts the proteins that keep fluids out of the lung, lowers a protective antioxidant, disrupts immune defenses and can lead to a condition known as 'alcoholic lung,' according to research to be presented at the conference, "Physiological Genomics and Proteomics of Lung Disease." view more (2006-11-03)
New lab test offers better prediction of HIV microbicide safety
Scientists at Albert Einstein College of Medicine of Yeshiva University have devised a laboratory test for predicting whether microbicides against HIV are safe for human use. view more (2009-07-10)
Characteristic pathological findings in reflux esophagitis
Recently, the number of patients with GERD has increased in Japan. However, there have been few reports about the pathological findings in the esophageal squamous epithelium, and there are differing opinions among pathologists about the findings considered characteristic of chronic reflux esophagitis. view more (2009-08-10)
Protein-Dependent "Switch" Regulates Intracellular Trafficking in Epithelial Cells
With findings highlighted on a recent cover of Developmental Cell, researchers at Weill Cornell Medical College in New York City have shed important new light on key trafficking mechanisms within epithelial cells. Epithelial cells line the outside of nearly all organs. view more (2007-12-12)
Cancer support cells may evolve, fuel tumor growth, study shows
University of North Carolina at Chapel Hill scientists have demonstrated in a living organism that cancers may cause surrounding supportive cells to evolve and ultimately promote cancer growth. view more (2005-12-19)
