PRPF6 regulated alternative splicing in colon cancer cell lines


ABSTRACT: PRPF6, an RNA binding component of the pre-mRNA spliceosome, is an essential driver of oncogenesis in colon cancer. PRPF6 is both amplified and overexpressed in colon cancer and cells with high PRPF6 levels are sensitive to its loss. Here we investigate alternative splicing changes in colon cancer cell lines following PRPF6 silencing by three different siRNA sequences. Two colon cancer cell lines (SW620 and KM-12), silencing of PRPF6 and control, 3 biological replicate samples for each group.

The spliceosome machinery is composed of multimeric protein complexes that generate a diverse repertoire of mRNA through coordinated splicing of heteronuclear RNAs. While somatic mutations in spliceosome components have been discovered in several cancer types, the molecular bases and consequences of spliceosome aberrations in cancer are poorly understood. Here we report for the first time that PRPF6, a member of the tri-snRNP (small ribonucleoprotein) spliceosome complex, drives cancer prolifera  ...[more]
