COMBINING TRANSLATION READTHROUGH INDUCING DRUGS AND NONSENSE MEDIATED DECAY PATWHAY INHIBITION TO THE CFTR RESCUE IN CYSTIC FIBROSIS CELL MODEL SYST…
2021
Nonsense mutations affect 10% of patients with cystic fibrosis and produce a premature termination codon in CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) mRNA causing early termination of translation and leading to lack of CFTR function. A potential therapy for nonsense mutations provides the use of small molecules able to overcome the premature stop codon (PTC) by a readthrough mechanism that lead to synthesis a complete CFTR protein. Despite the good results obtained from this approach, TRIDs efficiency is considerably reduced by the poor amount of target transcript, that is the mRNA containing the PTC. The readthrough, indeed, does not occur on the totality of target transcr…
Translational readthrough inducing drugs: a study of toxicity in mice models and in vitro safety validation of the specific readthrough process.
2022
Objective Nonsense mutations are responsible for 15% of Cystic Fibrosis (CF) patients due to the introduction of a premature stop codon (PTC) in the mRNA and the production of a truncated CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) protein1. A promising therapeutic approach for stop mutations is the suppression therapy by Translational Readthrough Inducing Drugs (TRIDs) to restore the expression of the protein2,3. Recently three new TRIDS (NV848, NV914, NV930) have been proposed and validated by several assays. Our work was focused on TRIDs NV848, NV914, NV930. Important aspects of TRIDs to be evaluated are their specificity towards PTC, to demonstrate that TRIDs do not inter…
