Body’s natural cell suicide program may trigger tumor development: Study

Cancer research springs a surprise. Researchers at Walter and Eliza Hall Institute in Melbourne have found that programmed cell death (apoptosis) or cell suicide plays a role in tumor development. This process is an important phenomenon in our body as it helps remove damaged cells. Now apoptosis has been found to be protective against cancer formation and autoimmune diseases.

Study implicates Fritz's role in human genetic disorders

Mutations in a gene known as "Fritz" may be responsible for causing human genetic disorders such as Bardet-Biedl syndrome, University of Texas at Austin developmental biologist John Wallingford and Duke University human geneticist and cell biologist Nicholas Katsanis have found.

Study finds ST131 a major cause of antimicrobial-resistant E. coli infections

The new strain, ST131, was a major cause of serious antimicrobial-resistant E. coli infections in the United States in 2007, researchers found. This strain has been reported in multiple countries and encountered all over the United States. In the study, researchers analyzed resistant E. coli isolates collected during 2007 from hospitalized patients across the country. They identified 54 ST131 isolates, which accounted for 67 percent to 69 percent of E. coli isolates exhibiting fluoroquinolone or extended-spectrum cephalosporin resistance.

Resveratrol suppresses inflammation in humans: Research

Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans, based on results from the first prospective human trial of the extract conducted by University at Buffalo endocrinologists.

Scientists identify enzyme to prevent beta-amyloids formation in Alzheimer patients

The brains of Alzheimer patients have high accumulations of the material beta-amyloid, which appear in the form of plaques. The precursors of these plaques are believed to be the underlying cause of the nerve cell loss that leads to the disruptions in memory that characterize Alzheimer's disease. The main aim of many Alzheimer therapies is therefore to inhibit the formation of beta-amyloid. Since beta-amyloid is cleaved from the so-called amyloid precursor protein (APP), scientists have focused on stopping the two enzymes that attack the precursor protein. These act like molecular scissors and cut out the beta-amyloid fragment. Blocking these scissors precludes the formation of beta-amyloid.

Epigenetic changes to DNA in breast cancers linked with environmental risk factors, tumor size: Study

Researchers from Brown University and the University of California San Francisco have found that epigenetic changes to DNA in breast cancers are related to environmental risk factors and tumor size, providing a window into the severity of the disease. The study is published in today's edition of PLoS Genetics. The researchers found that epigenetic profiles of tumors had a direct association with diet, alcohol, and tumor size.

FDA lifts hold, allows Geron to proceed with Phase I clinical trial of GRNOPC1 in spinal cord injury

Geron Corporation announced today that the U.S. Food and Drug Administration (FDA) has notified the company that the clinical hold placed on Geron's Investigational New Drug (IND) application has been lifted and the company's Phase I clinical trial of GRNOPC1 in patients with acute spinal cord injury may proceed.

Helicos' single-molecule sequencing technology for detection, quantification of novel small RNA

Helicos BioSciences Corporation today announced a publication demonstrating the detection and quantification of novel small RNA molecules using Helicos' single-molecule sequencing technology. These data confirm a long-held, unproven hypothesis that mammalian cells are capable of synthesizing RNA by copying RNA molecules directly.

Researchers discover tumor suppressor lincRNAs

The recent discovery of more than a thousand genes known as large intergenic non-coding RNAs (or "lincRNAs") opened up a new approach to understanding the function and organization of the genome. That surprising breakthrough is now made even more compelling with the finding that dozens of these lincRNAs are induced by p53 (the most commonly mutated gene in cancer), suggesting that this class of genes plays a critical role in cell development and regulation. Furthermore, the researchers identify one lincRNA in particular (lincRNA-p21), and demonstrate its critical role in suppressing the reading of many genes across the genome following p53 activation.

Bio-Path commences dosing in Liposomal Grb-2 Phase I cancer study

Bio-Path Holdings, Inc.,, a biotechnology company with drug development operations in Houston, Texas, announced today that the first patient has been dosed in a Phase I study of its cancer drug candidate, Liposomal Grb-2 (L-Grb-2 or BP-100-1.01), in patients with Acute Myeloid Leukemia (AML), Chronic Myelogenous Leukemia (CML), Acute Lymphoblastic Leukemia (ALL) or Myelodysplastic Syndrome (MDS).

Study on link between SNP and concentrations of serum creatinine

Scientists at deCODE genetics and colleagues at Radboud University in the Netherlands today describe how the impact of a single letter variation in the sequence of the human genome conferring risk of kidney disease varies with age and with the onset of other diseases. The study provides independent confirmation of the association made in an earlier study between a version of the the SNP, located on chromosome 16p12, and risk of chronic kidney disease. It also confirmed the link between the SNP and concentrations of serum creatinine, a key indicator of kidney function.

Researchers discover three disease-causing genes in Salmonella

Researchers have discovered a novel mechanism in Salmonella that affects its virulence and its susceptibility to antibiotics by changing its production of proteins in a previously unheard of manner. This allows Salmonella to selectively change its levels of certain proteins to respond to inhospitable conditions.

Researchers identify genetic mutation for Uner Tan Syndrome

A team of researchers from leading universities in Turkey and the United States have reported that they have identified the genetic mutation responsible for the Uner Tan Syndrome (UTS) using advanced genetic capture and sequencing technologies from Roche. The combined genomic technologies enabled the team of scientists to identify the causative mutation of this debilitating disease after years of mystery.

Life Technologies second-quarter Non-GAAP revenue increases 8% to $906 million

Life Technologies Corporation today announced results for its second quarter ending June 30, 2010. Non-GAAP revenue for the second quarter was $906 million, an increase of 8 percent over the $839 million reported for the second quarter of 2009. Excluding the impact of currency and prior acquisitions and divestitures, organic revenue for the quarter grew 6 percent over the same period in the previous year.

Prostate basal cell can spawn tumors in prostate gland: Research

A type of prostate cell that has been largely ignored by cancer researchers can, in fact, trigger malignant prostate cancer, according to new studies by Howard Hughes Medical Institute (HHMI) scientists and their colleagues.

FAO launches initiative to curb animal diseases

In an effort to prevent and control outbreaks of animal diseases and the associated costs, the U.N. Food and Agriculture Organization on Monday announced a new five-year initiative "to improve global response to disease outbreaks, implement effective prevention and containment strategies and manage risks," PANA/Afrique en ligne reports (7/28).

Scientists identify new targets to develop treatment for HD

Scientists at the Buck Institute for Age Research have discovered that a particular family of enzymes are involved in the breakdown of proteins that modify the production of toxic fragments that lead to the pathology of Huntington's disease. These enzymes, matrix metalloproteinases, provide new targets for drug therapies for the disease - targets that have already been shown to respond to cancer drugs currently in clinical development.

Genetic signals determine neurotransmitter use for communication

Cascades of genetic signals determine which neurotransmitter a brain cell will ultimately use to communicate with other cells. Now a pair of reports from biologists at the University of California, San Diego, have shown for the first time that electrical activity in these developing neurons can alter their chemical fate-and change an animal's behavior-by tweaking this genetic program.
