Protein misfolding diseases
Protein misfolding diseases include highly debilitating degenerative disorders like Alzheimer’s and Parkinson’s diseases [1]. The healthcare and financial burden linked to these pathologies has been steadily increasing over the past decade [2]. Actually, there is currently no efficient treatment for misfolding diseases as well as no reliable early diagnostic techniques for them [3]. It is known...
متن کاملProtein Misfolding Diseases.
The majority of protein molecules must fold into defined three-dimensional structures to acquire functional activity. However, protein chains can adopt a multitude of conformational states, and their biologically active conformation is often only marginally stable. Metastable proteins tend to populate misfolded species that are prone to forming toxic aggregates, including soluble oligomers and ...
متن کاملProtein Misfolding Diseases
Diseases caused by protein misfolding are an emerging pathologic category that are thought to share some basic common mechanisms and display impressive heterogeneity in terms of tissue involvement, age of onset and clinical features. The growing recognition of the impact that protein misfolding has on human diseases is certainly related to the phenomenon of population aging and the expansion of...
متن کاملIntracellular signaling by the unfolded protein response.
The unfolded protein response (UPR) is an intracellular signaling pathway that is activated by the accumulation of unfolded proteins in the endoplasmic reticulum (ER). UPR activation triggers an extensive transcriptional response, which adjusts the ER protein folding capacity according to need. As such, the UPR constitutes a paradigm of an intracellular control mechanism that adjusts organelle ...
متن کاملMolecular Pathways Molecular Pathways: The PERKs and Pitfalls of Targeting the Unfolded Protein Response in Cancer
The endoplasmic reticulum (ER) is a highly specialized organelle that provides an oxidizing, profolding environment for protein synthesis and maturation. The ER also hosts a dynamic signaling network that can sense and respond to physiologic changes that affect its environment, thereby influencing overall cell fate. Limitation of nutrients and oxygen have a direct effect on the efficiency of pr...
