Popis: | The hormone 1,25-(OH)2D3 has been shown to modulate cell proliferation and induce differentiation in several normal and malignant cell lines. In this work, we examined the effect of the hormone on the neuroblastoma SK-N-SH cell line. The steroid did not influence cell growth and cell cycle distribution, while retinoic acid inhibited proliferation and induced an accumulation of the cells in the G0/G1 phase of the cell cycle. 1,25-(OH)2D3 did not alter cell morphology. The activities of the 1-alpha- and 24-hydroxylases were low and not regulated by the hormone. The level of the total 1,25-(OH)2D3 receptor was low. We conclude that the lack of effect of 1,25-(OH)2D3 on the SK-N-SH cell line is related to the low level of the 1,25-(OH)2D3 receptor. |
