Researchers Develop Hybrid Protein Tools For Gene Cutting And Editing

MedicalNews Today, Article Date: 31 Aug 2010

An Iowa State University team of researchers has developed a type of hybrid proteins that can make double-strand DNA breaks at specific sites in living cells, possibly leading to better gene replacement and gene editing therapies. Read more

Development of a potential therapy for Friedreich ataxia based on transduction of the frataxin protein in the mitochondria

CAFA IS LAUNCHING A MAJOR RESEARCH PROJECT

This research project’s goal is to develop a therapy for Friedreich ataxia by targeting the actual cause of the illness, the reduction of frataxin. The project will therefore aim to administer the frataxin protein intravenously. However, as this protein does not spontaneously penetrate cells, it will be encapsulated with peptides (fragments of other proteins), in nanoparticles. Alternatively, the frataxin protein itself will be modified by adding peptides which will allow the proteins to penetrate not only the interior of cells, but also the interior of the mitochondria.

Symposium participants optimistic about finding first treatment for Friedreich's ataxia

Lipid Peroxides: More Sophisticated Than Their Reputation

ScienceDaily (Aug. 24, 2010) — Accumulation of lipid peroxides in the cell are associated with diseases and cellular stress. In the current issue of Proceedings of the National Academy of Sciences, researchers at Helmholtz Zentrum München and the Swedish medical university Karolinska Institutet show that lipid peroxides also play an important, yet-unrecognized role in the regulation of receptor tyrosine kinases.

Reference scientific paper:
12/15-lipoxygenase-derived lipid peroxides control receptor tyrosine kinase signaling through oxidation of protein tyrosine phosphatases.

The Monash University are seeking healthy participants for the control group, Understanding Motor Deficits in Friedreich's Ataxia

The aim of this study is to investigate the extent of motor overflow in people with Friedreich's ataxia. Motor overflow refers to involuntary movement which occurs on the opposite side of the body when voluntary movement takes place on one side.
