This work is based on using suppressor-tRNAs as a possible therapeutic tool for inherited cancer syndromes, where about 10-20% of the mutations described in are nonsense mutations. A suppressor-tRNA is a tRNA that can be altered to recognize premature stop codons (nonsense mutations), promoting their readthrough to produce full-length proteins. As a model, we used hereditary diffuse gastric cancer (HDGC), which is associated with mutations in CDH1 gene, encoding the adhesion molecule E-cadherin.
