The new study reports the development of suppressor tRNAs that have been optimized to target UAA stop codons, which arise when a glutamine CAA is mutated. The suppressor tRNA reads UAA as glutamine ...
Between 10 to 15% of all genetic diseases have the same underlying cause: a nonsense mutation. 1 This type of mutation results from a stop codon in the middle of a gene sequence, which terminates ...
(A) Suppressor tRNA readthrough strategy. Natural tRNAs with engineered anticodons are charged with canonical amino acids to enable readthrough of the premature termination codon (PTC). (B) Unnatural ...

Scientists design new RNA therapy to bypass mutations behind thousands of genetic diseases
A modified tRNA therapy bypassed premature genetic stop signals and restored working proteins in cystic fibrosis disease models.
For decades, biology students have learned one rule about the genetic code that supposedly has no exceptions: three specific DNA sequences act as stop signs, telling the cell’s protein-building ...
Gene editing can repair mutations that prematurely halt protein synthesis, resulting in incomplete peptides that cause various diseases. However, other approaches achieve the same effect without ...
