Genetic tag team orchestrates the cell cycle

By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle.

microRNAs appear essential for retinal health

Retinas in newborn mice appear perfectly fine without any help from tiny bits of genetic material called microRNAs except for one thing - the retinas do not work.

New study shows how sounds are amplified in the inner ear

St. Jude Children's Research Hospital investigators have found that an electrically powered amplification mechanism in the cochlea of the ear is critical to the acute hearing of humans and other mammals. The findings will enable better understanding of how hearing loss can result from malfunction of this amplification machinery due to genetic mutation or overdose of drugs such as aspirin.

Discovery of DNA variations in chromosome 6 that gives rise to neuroblastoma

Using advanced gene-hunting technology, an international team of researchers has for the first time identified a chromosome region that is the source of genetic events that give rise to neuroblastoma, an often fatal childhood cancer.

Adult human stem cells shown not to pose a cancer risk when implanted into different organs

A new study by UC Davis researchers provides evidence that methods using human bone marrow-derived stem cells to deliver gene therapy to cure diseases of the blood, bone marrow and certain types of cancer do not cause the development of tumors or leukemia.

New understanding of how a mole develops into melanoma

Researchers have discovered how a mole develops into melanoma by showing the interaction of two key proteins involved in 60-70 percent of tumors. The Penn State scientists also demonstrate that therapeutic targeting of these proteins is necessary for drugs to effectively treat this deadly form of cancer.

Gene sequence that can make half of us fatter is discovered

A gene sequence linked to an expanding waist line, weight gain and a tendency to develop type 2 diabetes has been discovered as part of a study published today in the journal Nature Genetics.

New discovery on role of vital protein that fights meningitus

A University of Leicester researcher has discovered how a protein in the blood - linked to defence against meningitis - plays a more vital role than previously understood in the body's immune defence system.

Clockwork PCR including sample prep

Analysis and diagnosis in a chip format are coming of age, but their practical application has been limited because until now, the sample usually had to be prepared separately and on a nonminiaturized scale.

Erythropoietin gene linked to severe diabetic eye, kidney diseases

Researchers at the John A. Moran Eye Center at the University of Utah and collaborative institutions have identified a gene called erythropoietin (EPO) that contributes to increased risk of severe diabetic eye and kidney diseases, called retinopathy and nephropathy.

New chemicals shield 'genome guardian'

Cancer Research UK scientists have discovered a potent group of chemicals that protect p53 - a major anti-tumour gene - from destruction, a study published in Cancer Cell* today (Monday) reveals.

Discovery of tenovins could lead to cancer cure

Scientists in Scotland have discovered a group of chemicals which protect one of the body's most important anti-cancer genes from destruction.

FGFR2 gene increases susceptibility to breast cancer

Much work has been done to identify genetic variations that predispose women to breast cancer. Previous work showed that variants in the gene called fibroblast growth factor receptor 2 (FGFR2) were associated with increased risk of the disease, but how these variants translated into increased risk was unknown.

Forty-one percent of registered nurses find generics are less effective than name brand drugs say American Society of Registered Nurses

In a national online survey conducted by the American Society of Registered Nurses, 41% of the 781 Registered Nurses surveyed on April 28 reported that generic drugs are less effective than their equivalent brand-name counterparts.

Most comprehensive kinome collection

Scientists from University of Helsinki, Institute of Molecular Medicine in Finland and OriGene Technologies joined effort in creating the most comprehensive kinome collection of nearly all predicted human protein kinases, including the functional kinases and their kinase-deficient counterparts. Equipped with this collection, the authors successfully identified novel kinase regulators in Hedgehog signaling pathway and in activation of Karposi's Sarcoma herpesvirus.

Whole-organ genomic survey depicts journey from normal to malignant cell

Whole-organ maps that superimpose genetic information over the terrain of cancerous bladders chart the molecular journey from normal cell to invasive cancer, an international research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports online at the journal Laboratory Investigation.

Cells lining milk ducts hold key to spread of ductal carcinoma in situ

When a form of cancer that begins in the milk ducts of the breast invades neighboring tissue to spread to other parts of the body, the cause lies not in the tumor cells themselves but in a group of abnormal surrounding cells that cause the walls of the duct to deteriorate like a rusty pipe, according to a new study led by Dana-Farber Cancer Institute researchers.

Secret to long life in lifestyle not genes

A research on the bone health of one of the oldest persons in the world, who recently died at the age of 114, reveals that there were no genetic modifications which could have contributed to this longevity.

It's official - there's a rogue fat gene!

Scientists from Oxford and Cambridge say in their second discovery they have found new genetic variants that influence fat mass, weight and risk of obesity and increase the chances of being fat, which may explain why some people are always battling with their weight.

Variations of the adiponectin gene may predict risk of breast cancer in women

According to a recent study, led by Virginia Kaklamani, MD, an oncologist at Northwestern Memorial Hospital and assistant professor of medicine, Northwestern University Feinberg School of Medicine, variations of the adiponectin gene, which regulates a number of metabolic processes, may increase a woman's risk of developing breast cancer.
