Article Synopsis
  • Microsatellite instability (MSI), often linked to mismatch repair deficiency in colorectal cancer (CRC), leads to numerous noncoding DNA mutations, particularly affecting RNA splicing sites.
  • This research shows that these noncoding mutations happen early in tumor development, even before the cancer cells become mutated in their coding regions, and are associated with altered splicing patterns in mRNA.
  • The altered RNA splicing impacts cellular differentiation and promotes the initiation of MSI CRC, indicating that these noncoding changes are significant for cancer progression before traditional coding mutations occur.

Post-transcriptional base modifications are important to the maturation process of transfer RNAs (tRNAs). Certain modifications are abundant and present at several positions in tRNA as for example the dihydrouridine, a modified base found in the three domains of life. Even though the function of dihydrourine is not well understood, its high content in tRNAs from psychrophilic bacteria or cancer cells obviously emphasizes a central role in cell adaptation.
