Splicing isoform-specific functional genomic in cancer cells

Alternative splicing is a regulated process whereby one gene can generate multiple mRNA isoforms susceptible to be translated into protein isoforms of various functions. Several publications report the aberrant expression of splicing isoforms in cancer cells and tissues. However, in most cases, their function remains to be established. In this review article, I will discuss the molecular tool available to perform isoform-specific functional genomics, the methodologies to quantify their effectiveness and the resulting isoform-specific phenotype in human cancer cell lines.
