| Outline of Final Research Achievements |
Alternative splicing of pre-mRNAs generates protein diversity from a limited number of genes.Alternative splicing occurs in a developmental stage-, sex- or tissue-specific manner and in response to the surrounding microenvironment.At the same time, aberrant alternative splicing participates in many genetic and acquired diseases including cancer.
Serine/Arginine splicing factors (SRSFs) family genes contain ultraconserved regions. Several SRSFs generate transcripts which contain pre-mature termination codons (PTCs).Interestingly, these transcripts are not degradiated by NMD in colon cancer cells. The aberrant expression of T-UCRs is posttranscriptionally regulated by miRNA and RNA-binding proteins.
In this study, we show that a nuclear protein, nucleolin regulates nuclear localization of T-UCRs in colon cancer cells.
