Taken together, we conclude that 1,25(OH)2D3 induces increased expression of cdk inhibitors , which mediates a G1 arrest , and this may be associated with differentiation of RA -resistant UF-1 cells toward mature granulocytes .
 ( protein: cdk inhibitors, None) , ( protein: cdk, None) , ( cell type: granulocytes, None) , ( cell line: UF-1 cells, None)
