ABSTRACT
BACKGROUND/AIMS:
The aim of this study was to investigate the effect of 1α,25-dihydroxyvitamin D3 on proliferation of human pancreatic cancer cell lines and to identify related cell cycle regulatory proteins with antiproliferative effects.METHODOLOGY:
Human pancreatic cancer cell lines SUIT-2 and its four sublines, and Panc-1, AsPC-1, and MiaPaCa-2 were treated with1α,25-dihydroxyvitamin D3. The number of cells was measured by the MTT method, and the cell cycle regulatory proteins were then analyzed by Western blotting.RESULTS:
Eight human pancreatic cancer cell lines expressed vitamin D receptor (VDR) mRNA. 1α,25-dihydroxyvitamin D3 inhibited proliferation of SUIT-2 and its sublines. We found p21 to be upregulated after 24 hours in S2-028, the cell line in which proliferation was most inhibited by 1α,25-dihydroxyvitamin D3.CONCLUSIONS:
1α,25-dihydroxyvitamin D3 inhibited proliferation of pancreatic cancer cells and is involved in the upregulation of cyclin-dependent kinase inhibitor p21.
