The Lost Boys: Neglected Generation Of Young Men With Duchenne Muscular Dystrophy Demand More Support

Medicals News Today,  Article Date: 11 May 2010

New research from the University of Bristol has found that the rights and needs of young men with Duchenne muscular dystrophy (DMD) - a life-limiting, inherited neuromuscular disease - are being severely restricted by the failure of many services to provide good planning and support.

Mechanism elucidated for a rare disease

May 04 2010 
Scientists at the Friedrich Miescher Institute for Biomedical Research (FMI, part of the Novartis Research Foundation) have dissected one of the molecular mechanisms underlying Friedreich's ataxia. In doing so, they have shed new light on the pathogenic mechanism of the disease. These findings could lead to the development of new therapeutic approaches for what is, as yet, an incurable condition. The results of the study were recently published in the journal EMBO Molecular Medicine

Abstract

Thiazolidinediones (TZDs) activate peroxisome proliferator-activated receptor gamma (PPARγ) and are used clinically to help restore peripheral insulin sensitivity in Type 2 diabetes (T2DM). Interestingly, long-term treatment of mouse models of Alzheimer's disease (AD) with TZDs also has been shown to reduce several well-established brain biomarkers of AD including inflammation, oxidative stress and Aβ accumulation. While TZD's actions in AD models help to elucidate the mechanisms underlying their potentially beneficial effects in AD patients, little is known about the functional consequences of TZDs in animal models of normal aging. Because aging is a common risk factor for both AD and T2DM, we investigated whether the TZD, pioglitazone could alter brain aging under non-pathological conditions.
