Faster biological ageing linked to increased cancer risk

Posted: 28 Mar 2013 06:51 AM PDT

An international team of scientists involving researchers from Karolinska Institutet has found new evidence that links faster 'biological' ageing to the risk of developing several age-related diseases - including heart disease, multiple sclerosis and various cancers.

The study involved scientists in 14 centres across 8 countries, working as part of the European ENGAGE consortium. The research is published online in the journal Nature Genetics.

Riding the exosome shuttle from neuron to muscle

Important new research from UMass Medical School demonstrates how exosomes shuttle proteins from neurons to muscle cells where they take part in critical signaling mechanisms, an exciting discovery that means these tiny vehicles could one day be loaded with therapeutic agents, such as RNA interference (RNAi), and directly target disease-carrying cells. The study, published this month in the journal Neuron, is the first evidence that exosomes can transfer membrane proteins that play an important role in cell-to-cell signaling in the nervous system.

Novel Gene Drives Development of Different Types of Ovarian Cancer

Researchers at Mayo Clinic Cancer Center have identified a novel gene that can contribute to a woman's susceptibility for developing ovarian cancer. Researchers identified the gene, called HNF1B, through large-scale analysis of more than 16,000 women with ovarian cancer and more than 26,000 healthy women. Results of the study are published in the current issue of the journal Nature Communications.

HIV sufferers need hepatitis safeguards

Stronger protections are needed to prevent people with HIV from also becoming infected with hepatitis, researchers argue in a new study led by Michigan State University.
