Signaling pathways of proteostasis network unraveled by proteomic approaches on the understanding of misfolded protein rescue.

چکیده
Attempts to promote normal processing and function of F508del-CFTR, the most common mutant in cystic fibrosis (CF), have been described as potential therapeutic strategies in the management of this disease. Here we described the proteomic approaches, namely two-dimensional electrophoresis (2DE), mass spectrometry (MS), and bioinformatics tools used in our recent studies to gain insight into the proteins potentially involved in low-temperature or mutagenic treatment-induced rescue process of F508del-CFTR. The proteins identified are part of the proteostasis network, such as the unfolded protein response (UPR) signaling pathways that may regulate the processing of CF transmembrane conductance regulator (CFTR) through the folding and trafficking progression. The complete characterization of these signaling pathways and their regulators in CF will certainly contribute to the development of novel therapeutic strategies against CF.

Backgroud: Protein-protein interaction, plays a key role in signal transduction in signaling pathways. Different approaches are used for prediction of these interactions including experimental and computational approaches. In conventional node-edge protein-protein interaction networks, we can only see which proteins interact but ‘structural networks’ show us how these proteins inter...
متن کاملCellular proteostasis: degradation of misfolded proteins by lysosomes
Proteostasis refers to the regulation of the cellular concentration, folding, interactions and localization of each of the proteins that comprise the proteome. One essential element of proteostasis is the disposal of misfolded proteins by the cellular pathways of protein degradation. Lysosomes are an important site for the degradation of misfolded proteins, which are trafficked to this organell...

THE MAINTENANCE OF PROTEIN HOMEOSTASIS (proteostasis) is essential for all functions of cells and the organism and results from a tightly controlled balance between synthesis, folding, and selective degradation of damaged and aggregated proteins. Multiple physiological situations challenge the proteome, including developmental changes or adaptation to environmental stress conditions, as well as...

Interferons (IFNs) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. Although IFNs have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. IFNs exert their pleiotropic effects through their multisubunit cell surface recept...
