Breakthrough in treatment of sca type 6

Spinocerebellar ataxia type 6 SCA6 is a rare, late-onset, autosomal dominant disorder, which, like other types of SCAis characterized by dysarthriaoculomotor disorders, peripheral neuropathyand ataxia of the gait, stance, and limbs due to cerebellar dysfunction. Unlike other types, SCA 6 is not fatal.

Early-bird discount available for a limited time. Pastor and colleagues identify FDA-approved small molecules that selectively reduce the toxic polyglutamine-expanded protein in SCA6. Selectively targeting disease-causing genes without disrupting cellular functions is essential for successful therapy development. In spinocerebellar ataxia type 6 SCA6 , achieving this selectivity is particularly complicated as the disease-causing gene produces two proteins that contain an expanded polyglutamine tract. In this study, Pastor and colleagues identified several Food and Drug Administration FDA approved small molecules that selectively reduce the levels of one of these polyglutamine-containing proteins without affecting the levels of the other protein, which is essential for normal brain function.

Spinal cerebellar ataxia 6 SCA6 is an inherited neurological condition which has a debilitating impact on motor coordination. Affecting around 1 in , people, the rarity of SCA6 has seen it attract only limited attention from medical researchers. To date, there is no known cure and only limited treatment options exist. Now, a team of McGill University researchers specializing in SCA6 and other forms of ataxia, have published findings that not only offer hope for SCA6 sufferers but may also open the way to developing treatments for other movement disorders. In mice affected by SCA6, the McGill team, led by biology professor Alanna Watt, found that exercise restored the health of cells in the cerebellum, the part of the brain implicated in SCA6 and other ataxias. The reason for the improvement, the researchers found, was that exercise increased levels of brain-derived neurotrophic factor BDNF , a naturally occurring substance in the brain which supports the growth and development of nerve cells. Importantly for patients with a movement disorder, for whom exercise may not always be feasible, the team demonstrated that a drug that mimicked the action of BDNF could work just as well as exercise, if not better. The drug, they found, worked to arrest the decline only if it was given before the onset of outwardly visible symptoms. Materials provided by McGill University.

Spinocerebellar ataxia type 6 SCA6 is characterized by adult-onset, slowly progressive cerebellar ataxia, dysarthria, and nystagmus. The age of onset ranges from 19 to 73 years; mean age of onset is between 43 and 52 years.

Daily Healthzine. In , David Nichols, a year-old mechanical engineer from the USA, fell while rock climbing on the Enchantments Mountain range in Washington, suffering a brain injury. After the incident, he experienced difficulty with coordinated movements such as balance, posture, walking, and sitting, along with tremors in his legs and right arm. Moreover, he could barely talk. Speaking to Happiest Health from his Portland, Oregon home, Nichols explained that he was diagnosed with a rare movement disorder named spinocerebellar ataxia type 6 SCA-6 soon after. According to a study, SCA-6 is a rare condition that progresses with age, affecting 2.

A subsequent case study showed acetazolamide to be useful in treatment of episodic ataxia and positional vertigo with central positional nystagmus seen in SCA6, but ineffective for chronic ataxia [ 61 ]. In general, in silico drug design speeds up the process of finding new drugs, minimizes the number of substances that must be created and tested in experiments to check their toxic and allergenic effects and offers important new information on the molecular causes of disease and drug interactions.
