FIGURE 1.
Splicing-factor alterations in human tumors. Human tumors exhibit somatic mutations in splicing regulators, or changes in splicing-factor levels in response to cell signaling or transcriptional regulation. These alterations in splicing factors promote differential splicing patterns in tumors compared to normal tissues. Alterations in alternative splicing events lead to the production of pro-tumorigenic isoforms that have been linked to various steps of tumorigenesis, including proliferation, apoptosis, invasion, metabolism, angiogenesis, DNA damage, or even drug resistance and immune response.
