Wolfram Syndrome as a Mitochondriopathy

Publication: nature.com | Publication Date: March 6, 2018

Authors: Benjamin Delprat, Tangui Maurice & Cécile Delettre

Abstract

Wolfram syndrome (WS) is a rare neurodegenerative disease, the main pathological hallmarks of which associate with diabetes, optic atrophy, and deafness. Other symptoms may be identified in some but not all patients. Prognosis is poor, with death occurring around 35 years of age. Read more

Wolfram Syndrome and its Degenerative Factors and Treatments

Publication: undergradsciencejournals.okstate.edu | Publication Date: 2021

Authors: Olivia Tolbert

Abstract

With advancements in treatments for Wolfram syndrome come new ways to possibly treat or further understand other degenerative diseases such as Alzheimer’s and Parkinson’s. There are multiple forms of treatments being devised, one path is to limit the frequency of cell death and halt further symptoms the other to prevent or replace the mutated cells. Read more

WFS1 Mutation Frequency 60-fold Higher in Ashkenazi Jewish Individuals – Results in Wolfram Spectrum and Increased Risk for T2DM

Publication: pubmed.ncbi.nlm.nih.gov | Publication Date: July 16, 2018

Authors: Vikas Bansal, Bernhard O Boehm, Ariel Darvasi

Abstract

Aims/hypothesis: Wolfram syndrome is a rare, autosomal recessive syndrome characterised by juvenile-onset diabetes and optic atrophy and is caused by bi-allelic mutations in the WFS1 gene. In a recent sequencing study, an individual with juvenile-onset diabetes was observed to be homozygous for a rare missense variant (c.1672C>T, p.R558C) in the WFS1 gene. Read more

Valproate to Increase WFS-1 Expression

Publication: journals.plos.org | Publication Date: January 6, 2009

Authors: Chihiro Kakiuchi,Shinsuke Ishigaki,Christine M. Oslowski,Sonya G. Fonseca,Tadafumi Kato & Fumihiko Urano

Abstract

Background

Valproate is a standard treatment for bipolar disorder and a first-line mood stabilizer. The molecular mechanisms underlying its actions in bipolar disorder are unclear. It has been suggested that the action of valproate is linked to changes in gene expression and induction of endoplasmic reticulum (ER) stress-response proteins. Read more

The Race to Treat Rare, Fatal Syndrome May Help Others With Common Disorders Like Diabetes

Publication: science.org | Publication Date: February 11, 2021

Authors: Mitch Leslie

A Revealing Flaw: A rare disease that cripples a key cellular organelle holds clues to treating more common conditions.

Abstract

Maureen Marshall-Doss says the first sign that her vision was deteriorating came when she misidentified the color of a dress. At a backyard get-together about 20 years ago, the Indianapolis resident pointed out an attractive yellow dress another woman was wearing. “You see that as yellow? She’s wearing a pink dress,” Marshall-Doss recalls her husband responding. Read more

The impact of the unfolded protein response on human disease

Publication: rupress.org | Publication Date: June 25, 2012

Authors: Shiyu Wang, Randal J. Kaufman

A central function of the endoplasmic reticulum (ER) is to coordinate protein biosynthetic and secretory activities in the cell. Alterations in ER homeostasis cause accumulation of misfolded/unfolded proteins in the ER. Read more

Role of Endoplasmic Reticulum Stress in Metabolic Disease and Other Disorders

Publication: ncbi.nlm.nih.gov | Publication Date: July 1, 2012

Authors: Lale Ozcan and Ira Tabas

Abstract

Perturbations in the normal functions of the endoplasmic reticulum (ER) trigger a signaling network that coordinates adaptive and apoptotic responses. There is accumulating evidence implicating prolonged ER stress in the development and progression of many diseases, including neurodegeneration, atherosclerosis, type 2 diabetes, liver disease, and cancer.
