We demonstrate that guanabenz acetate (GA) increases both the phosphorylation of the eukaryotic translation initiation factor 2alpha subunit and the splicing of Xbp1, key components of the UPR. Altogether these data show that modulation of protein folding regulation is beneficial for Oculopharyngeal muscular dystrophy (OPMD) and promote the further development of GA or its derivatives for treatment of OPMD in humans

Matrin 3 (MATR3) is a novel protein interactor of PABPN1. MATR3 also binds and regulates the levels of long non-coding RNA (lncRNA) Neat1 and together with PABPN1 is required for normal paraspeckle function.

Expression levels of these cytokines were highly correlated in controls, but this correlation pattern was disrupted in OPMD. The levels of these 6 cytokines were not altered in expPABPN1 carriers at a pre-symptomatic stage, suggesting that this group of cytokines is a potential biomarker for muscle weakness in OPMD.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
