What this research studies

Researchers will study how two splicing-related proteins (SRSF1 and BCAS2) change RNA messages in pancreatic and breast tumors and drive cancer behavior. They will use lab-grown tumor organoids, genetic mouse models, and tumor samples to see which altered RNA isoforms promote tumor growth. High-throughput RNA sequencing and computational analysis will find the specific mis-spliced RNAs, and scientists will then manipulate those isoforms to test whether correcting them slows or stops tumors. The team aims to identify cancer-specific RNA targets that could be attacked by future therapies such as antisense oligonucleotides.

Who could benefit from this research

Good fit: People with pancreatic cancer or basal-like (aggressive) breast cancer, especially whose tumors show splicing-factor changes like SRSF1 overexpression or mutant KRAS, would be most relevant to this work.

Not a fit: Patients whose tumors do not show splicing abnormalities or people seeking immediate clinical treatment are unlikely to gain direct benefit from this preclinical research.

Why it matters

Potential benefit: If successful, this research could point to new therapies that specifically target cancer-causing RNA isoforms, potentially improving treatment options for pancreatic and certain breast cancers.

How similar studies have performed: Targeting splicing or specific RNA isoforms has shown promise in laboratory models and antisense drugs work for some genetic diseases, but applying these approaches to pancreatic and breast cancer remains largely experimental.
