Forskare vid Cold Spring Harbor Laboratory rapporterar att de identifierat en tre-delad molekylär krets som involverar SRSF1, Aurora kinas A (AURKA) och MYC som driver aggressiv pankreasductal adenocarcinom. I laboratoriemodeller bröt en spliceväxlande antisense-oligonukleotid designad för att ändra AURKA-splicing kretsen, minskade tumörcelltvivabilitet och utlöste programmerad celldöd.

Researchers at Spain's National Cancer Research Centre (CNIO) have developed a comprehensive catalog of mutational 'scars' in DNA caused by cancer. This breakthrough, published in Nature, could help bypass resistances to treatments like PARP inhibitors. The study analyzes thousands of tumor samples to identify key genetic patterns.
