Abstract

Inhibitory effects of 1,25(OH)2D3 and D3 on growth of four neoplastically derived cells were observed in human acute leukemia cell culture CEM-C-1 and CEM-C-7, human cervical carcinoma cell lines C-4-1 and human epithelioid carcinoma cells of cervix HeLa S3K. Concurrently, in dexamethasone-responsive cells C-4-1 and HeLa S3K there was a 1,25(OH)2D3 and D3 induced elevation of alkaline phosphatase with 1,25(OH)2D3 showing the greater effects. It is supposed that vitamins D3-induced alkaline phosphatase activity in malignant cells, which is proposed to be a possible marker of cell differentiation, can be associated with the membrane effects of these vitamins.
