Finding that links ALS/ataxia to cellular stress opens new approaches for treatment

(University of Utah) Scientists at University of Utah Health report for the first time that a protein, called Staufen1, accumulates in cells of patients suffering from degenerative ataxia or amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease. Depleting the protein from affected mice improved symptoms including motor function. These results suggest that targeting Staufen1 could have therapeutic potential in people. The research is published in Nature Communications.

Abstract Tau-tubuline kinases (TTBK) are a family of serine/threonine and tyrosine kinases recently discovered and implicated in the phosphorylation of important substrates such as tau, tubuline or TDP-43. Its two homologs, TTBK1 and TTBK2, show different expression patterns and different involvements in physiological mechanisms of great importance such as mitosis, ciliogenesis and neurotransmission. Their phosphorylation activity has also linked them to the development of neurodegenerative diseases like Alzheimer's disease, amyotrophic lateral sclerosis or spinocerebellar ataxia type 11. There are currently only ...

Abstract Protein coding sequences represent only 2% of the human genome. Recent advances have demonstrated that a significant portion of the genome is actively transcribed as non-coding RNA molecules. These non-coding RNAs are emerging as key players in the regulation of biological processes, and act as "fine-tuners" of gene expression. Neurological disorders are caused by a wide range of genetic mutations, epigenetic and environmental factors, and the exact pathophysiology of many of these conditions is still unknown. It is currently recognized that dysregulations in the expression of non-coding RNAs ar...

Abstract Neurodegenerative diseases (NDDs) are incapacitating disorders that result in progressive motor and cognitive impairment. These disease include Alzheimer's disease the most common cause of dementia, frontotemporal dementia, amyotrophic lateral sclerosis, dementia with Lewy bodies, Parkinson's, Huntington's, Friedreich's ataxia, and prion disease. Dementia causing NDDs impose a high social and economic burden on communities around the world. Rapid growth in knowledge regarding the pathogenic mechanisms and disease-associated biomarkers of these diseases in the past few decades have accelerated the developm...

Publication date: May 2018 Source:Neurochemistry International, Volume 115 Author(s): Zhihui Zhu, Georg Reiser Small heat shock proteins (sHsps) are a group of proteins with molecular mass between 12 and 43 kDa. Currently, 11 members of this family have been classified, namely HspB1 to HspB11. HspB1, HspB2, HspB5, HspB6, HspB7, and HspB8, which are expressed in brain have been observed to be related to the pathology of neurodegenerative diseases, including Parkinson's, Alzheimer's, Alexander's disease, multiple sclerosis, and human immunodeficiency virus-associated dementia. Specifically, sHsps interact with misfolding ...
