Alternative splicing is a crucial mechanism for generating protein diversity. Different splice variants of a given protein can display different and even antagonistic biological functions. Therefore, appropriate control of their synthesis is required to assure the complex orchestration of cellular processes within multicellular organisms. Mutations in cis-acting splicing elements or changes in the activity of regulatory proteins that compromise the accuracy of either constitutive or alternative splicing could have a profound impact on human pathogenesis, in particular in tumor development and progression. Mutations in splicing elements, for example, have been found in genes such as LKB1, KIT, CDH17, KLF6 and BRCA1, and changes in trans-acting regulators can affect the expression of genes such as Ron, RAC1 and CD44.
