Oncogenic signal transduction driving alternative splicing in cancer. The RAS/RAF/ERK, PI3K/AKT and Wnt signaling pathways play an important role in regulating splicing factor via transcriptional regulation and/or post-translational modification, which lead to aberrant-splicing events that promote oncogenesis.
