Cetuximab recommended for colorectal cancer tumors without mutation in KRAS gene

In a report published in the July 2010 issue of the American Society for Clinical Oncology Post, new recommendations on the use of the drug cetuximab have been issued after officials halted enrollment in a phase III clinical trial in patients with spread of colon cancer into regional lymph nodes whose tumors had been surgically removed.

AMPK may regulate epigenetic mechanism: Research

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.Biologists have been studying how AMPK works for several decades and know that once it is activated, AMPK turns on a large number of genes by passing the "make more energy" message through numerous signaling cascades in the cell. What was not known, until now, was that AMPK also works via an epigenetic mechanism to slow down or stop cell growth.

Resveratrol concentration impacts cancer risk mitigation: Study

Agricultural Research Service (ARS) chemist Thomas Wang, who specializes in cancer prevention research, has reported evidence that for some dietary compounds, length of exposure over time may be key to whether or not ingestion leads to a beneficial, or detrimental, effect.Scientists do not know exactly why one person develops cancer and another does not. But they do know that certain nutrients might increase or decrease cancer risk. There are "layers" of factors involved in the development of cancer, and Wang is studying the layers involving peoples' diet complexity and gene expression.

Bioethics through the lens of literature

What if I were grown only so that my organs could be harvested, and I had to care for others whose organs are being taken, too, while I wait for my own death? What if doctors cut off a piece of the tumor that killed me and grew it in a lab for the next sixty years? What if scientists discovered a gene that would ensure my happiness no matter what life throws at me?

Study on how cellular defence systems keep themselves in check from damaging cells themselves

When cells are attacked by bacteria they use all means at their disposal to defend themselves. But cellular defence systems can damage the cells themselves and so need to be kept tightly in check. Recent results help us to understand how this is done and give pointers to new ways of combating disease. Matthias Farlik in the group of Thomas Decker at the Centre for Molecular Biology of the University of Vienna (Max F. Perutz Laboratories) and Mathias Müller of the University of Veterinary Medicine, Vienna have published these findings in the current issue of the journal "Immunity".

Study compares denture stomatitis genes with whole transcriptome for salivary biomarker analysis

The goal of the study was to compare whole-transcriptome, mucosal gene expression in Candida albicans (a parasitic fungus that can infect the mouth) associated chronic denture stomatitis to that of healthy oral mucosa and perform proteomic analyses of potential salivary biomarkers. Denture stomatitis is a condition in which the mucosa underneath a denture becomes inflamed and sometimes painful.

Researchers develop new strategy for treating multiple myeloma

Multiple myeloma is one of the most common blood cancers, and at present considered to be incurable. In a new study from Uppsala University, researchers now present a conceptually new model for the development and progression of multiple myeloma. The study was done in collaboration with Vrije Universitet Brussels and is published in the July edition of the on-line journal PLoS ONE.

Penn researchers reverse cognitive decline in fruit flies with Alzheimer's gene mutation

Investigators have found that fruit fly (Drosophila melanogaster) males -- in which the activity of an Alzheimer's disease protein is reduced by 50 percent -- show impairments in learning and memory as they age. What's more, the researchers were able to prevent the age-related deficits by treating the flies with drugs such as lithium, or by genetic manipulations that reduced nerve-cell signaling.

Study reveals improved process to obtain, store RNA from lung tumor biopsies

Analyzing the genes expressed by cancer cells allows for a better understanding of that patient's specific disease and in turn, a more personalized approach to treatment. But obtaining the RNA from a tumor in the lungs in order to conduct the genetic analysis is a challenging prospect. Currently, lung cancer researchers are limited to using RNA extracted from early-stage tumors removed during surgery. The small quantities of tissue extracted during routine diagnostic biopsies have not been useful to researchers, due to their small size and the variety of ways they have been processed.

Fatness drives inactivity, not the other way around

According to a recent longitudinal study in children, inactivity does not lead to fatness! Moreover, the authors concluded that fatness is driving inactivity, and not the other way around. The authors noted that this "reverse causality" explains the observed association between inactivity and fatness. It also explains the repeated failures of the attempts to reduce childhood obesity by increasing physical activity. The study was published in the Archives of Disease in Childhood by Dr. Brad Metcalf and colleagues from Plymouth, UK.

Study suggests chronic kidney disease affects persons of African, Hispanic heritage at higher rate

Chronic kidney disease affects millions in North America, with persons of African heritage being at a four-fold higher risk and those of Hispanic heritage having a two-fold higher risk compared to the rest of the population. An international study carried out by Dr. Karl Skorecki, from the Technion-Israel Institute of Technology and Rambam Medical Center in Haifa, and his team points to the APOL1 gene as involved in the increased risk of kidney disease in this high-risk population. The results are to be published online in Springer's journal Human Genetics.
