Many of the gene mutations found in genetic disorders, including cancer, result
in premature termination codons (PTC) and the rapid degradation of their mRNAs by
nonsense-mediated RNA decay (NMD). We used virtual library screening, targeting a
pocket in the SMG7 protein, a key component of the NMD mechanism, to identify
compounds that disrupt the SMG7-UPF1 complex and inhibit NMD. Several of these
compounds upregulated NMD-targeted mRNAs at nanomolar concentrations, with
minimal toxicity in cell-based assays. As expected, pharmacologic NMD inhibition
disrupted SMG7-UPF1 interactions. When used in cells with PTC-mutated p53,
pharmacologic NMD inhibition combined with a PTC "read-through" drug led to
restoration of full-length p53 protein, upregulation of p53 downstream
transcripts, and cell death. These studies serve as proof-of-concept that
pharmacologic NMD inhibitors can restore mRNA integrity in the presence of PTC
and can be used as part of a strategy to restore full-length protein in a variety
of genetic diseases.
