INTRODUCTION Vitamin D deficiency and vitamin D receptor (VDR) gene polymorphism, FokI, is reported to increase the risk of many cancers. Role of vitamin D and its receptor polymorphisms in ovarian cancer has not been clearly defined. OBJECTIVE To study the levels of serum vitamin D and occurrence of vitamin D receptor gene polymorphism (FokI) in cases of ovarian cancer. MATERIAL AND METHOD...

The biologically active form of vitamin D, i.e., 1,25-dihydroxycholecalciferol or calcitriol, plays an important role in bone metabolism and calcium homeostasis, which is often disturbed at the onset of lactation in high milk-yielding domestic ruminants. Gene transcription is modulated via vitamin D receptors, but nongenomic effects of vitamin D via membrane receptors have also been described. ...

AIM OF THE STUDY Vitamin D receptor (VDR) expression and serum vitamin D scores in oral premalignant lesions and oral cancer have not been widely analyzed. The role of vitamin D supplementation in advanced oral cancer for improving quality of life (QOL) is also a matter of research. MATERIAL AND METHODS Vitamin D receptor expression and vitamin D scores were analyzed in normal oral mucosa (n ...

Aim The role of vitamin D on host immunity defense against tuberculosis infection has long been known. Deficiency vitamin D and vitamin D receptor polymorphism are strongly associated with the susceptibility of tuberculosis in four seasons countries. As a country with sufficient sunlight, the incidence of tuberculosis in Indonesia remains high. The aim of this study is to asses the association ...

The vitamin D receptor mediates the signal of 1 alpha, 25-dihydroxyvitamin D3 by binding to vitamin D responsive elements in DNA as a homodimer or as a heterodimer composed of one vitamin D receptor subunit and one retinoid X receptor subunit. We have mapped the dimerization interfaces of the vitamin D receptor that is involved in homo- or heterodimer formation in the absence of DNA. While dele...

Objective(s): The aim of this study was to investigate the effect of vitamin D on glucose metabolism, as well as the expression of five key genes involved in the development of diabetes complications in liver tissue of diabetic rats. Materials and Methods: Twenty-four male Sprague–Dawley rats were randomly divided into three groups (8 ra...
