The role of 1,25(oh)2d3 and its analogs in proliferation and differentiation of squamous cell carcinoma of the head and neck – literature review

Abstract

Epidemiological studies correlate sun or UV light exposure with a lower incidence of a variety of malignancies, including breast, colon and prostate cancer. The biologically active 1,25(OH)2D3 and its analogs have been shown to have antiproliferative and differentiating effects in a variety of malignant and non-malignant cells. The effects of 1,25(OH)2D3 are mediated by the binding of calcitriol to a specific intracellular receptor, vitamin D receptor [VDR]. The aim of this study is to review the literature concerning the role of 1,25(OH)2D3 and its analogs in squamous carcinoma cell lines of the head and neck (SCCHN).

Keywords: 1,25(OH)2D3; vitamin D3; squamous cell carcinoma of the head and neck.
