Outline of Final Research Achievements |
This project aims to clarify the mRNA splicing mechanism in which Ca2+-activated Cl- channel modulator CLCA is switched to its truncated isoform (CLCA-t). Using the splicing reporter plasmids including the gene region (minigene) of exons 8, 9 and 10, the splicing pattern of which is distinct between two CLCA isoforms, the splicing pattern observed in CLCA-t (exon 8+10) was shown to be attenuated by the differentiation of epithelium. Next, we examined the epigenetic regulation of the selective splicing of CLCA in the 3-dimensional mucosal culture model. Overall, trimethylation of histone that reportedly alters the chromatin structure is likely to contribute to the splicing pattern in the CLCA isoforms.
