| Research Abstract |
Insulin producing pancreatic β-cells are highly differentiated tissue, In order to elucidate molecular mechanisms of transcriptional regulation in β-cells, we constructed a novel full-length cDNA library by Vector-capping method from rat β-cell line INS-1D cells, and performed a 5'-one pass shotgun sequencing with 26,976 clones, resulting in 6,042 clusters. We identified novel transcriptional start sites (TSSs) and possible transcriptional regulatory regions for some genes. We also obtained several functional non-coding RNA (ncRNA) candidates, which may be involved in insulin secretion. Thus, our system should serve as a novel tool for investigating 'RNA world' of pancreatic β-cells.
