Pfizer aims to become industry leader in gene therapy with acquisition of Bamboo Therapeutics, Inc.

Pfizer announces today acquisition of Bamboo Therapeutic, Inc. as a part of a growing commitment to gene therapy and rare disease, including FA. Bamboo’s portfolio includes potential best-in-class rAAV-based gene therapies in two priority areas: neuromuscular, with a pre-clinical asset for Duchenne Muscular Dystrophy (DMD); and central nervous system, with pre-clinical assets for Friedreich’s Ataxia and Canavan disease, and a Phase I asset for Giant Axonal Neuropathy.

9th Annual Friedreich’s Ataxia Symposium – 2016 CHOP/FARA – Call For Abstracts

The Friedreich’s Ataxia Research Alliance (FARA) and the Children’s Hospital of Philadelphia (CHOP) would like to invite young investigators—graduate/medical students and post-doctoral fellows—to submit abstracts for the 9th Annual Friedreich’s Ataxia Symposium to be held on October 16-17, 2016 in King of Prussia, PA. The symposium will include a reception on the evening of Sunday, October 16, and talks throughout the day on Monday, October 17, 2016. Posters will be up throughout the meeting with specific poster sessions during the reception on the 16th and breakfast and lunch on the 17th. We encourage you to share this information with young investigators in your lab who would benefit from gaining greater exposure to the FA community in addition to the experience of presenting their research data.

The Symposium presents an opportunity to engage with the patient community as well as network with other investigators. We wish to give young investigators the opportunity to meet and interact with FA patient families and to recognize how their work directly impacts patients’ lives while simultaneously giving the families more opportunity to learn about ongoing research.

The Replication of Frataxin Gene Is Assured by Activation of Dormant Origins in the Presence of a GAA-Repeat Expansion

It is well known that DNA replication affects the stability of several trinucleotide repeats, but whether replication profiles of human loci carrying an expanded repeat differ from those of normal alleles is poorly understood in the endogenous context. We investigated this issue using cell lines from Friedreich's ataxia patients, homozygous for a GAA-repeat expansion in intron 1 of the Frataxin gene. By interphase, FISH we found that in comparison to the normal Frataxin sequence the replication of expanded alleles is slowed or delayed. According to molecular combing, origins never fired within the normal Frataxin allele. In contrast, in mutant alleles dormant origins are recruited within the gene, causing a switch of the prevalent fork direction through the expanded repeat. Furthermore, a global modification of the replication profile, involving origin choice and a differential distribution of unidirectional forks, was observed in the surrounding 850 kb region. These data provide a wide-view of the interplay of events occurring during replication of genes carrying an expanded repeat.

Metal Homeostasis Regulators Suppress FRDA Phenotypes in a Drosophila Model of the Disease

Friedreich's ataxia (FRDA), the most commonly inherited ataxia in populations of European origin, is a neurodegenerative disorder caused by a decrease in frataxin levels. One of the hallmarks of the disease is the accumulation of iron in several tissues including the brain, and frataxin has been proposed to play a key role in iron homeostasis. We found that the levels of zinc, copper, manganese and aluminum were also increased in a Drosophila model of FRDA, and that copper and zinc chelation improve their impaired motor performance. By means of a candidate genetic screen, we identified that genes implicated in iron, zinc and copper transport and metal detoxification can restore frataxin deficiency-induced phenotypes. Taken together, these results demonstrate that the metal dysregulation in FRDA includes other metals besides iron, therefore providing a new set of potential therapeutic targets.

The significance of intercalated discs in the pathogenesis of Friedreich cardiomyopathy

Friedreich ataxia (FRDA) is an autosomal recessive disorder with a complex clinical and neuropathological phenotype, but the most frequent cause of death is cardiomyopathy. The principal autopsy findings in FRDA hearts are concentric hypertrophy, enlargement of cardiomyocytes, myofiber necrosis, inflammatory infiltration, scarring, and random accumulation of iron. In addition, the myocardium shows generalized disorganization of intercalated discs (ICD), the Velcro-like end-to-end connections of heart fibers that provide mechanical cohesion and ionic coupling. The principal components of ICD are fascia adherens junctions (FAJ), desmosomes, and gap junctions. Frataxin deficiency in FRDA may cause improper assembly of ICD early in life, making hearts vulnerable to mechanical stress in childhood and adolescence.
