Seasonal variation in expression of markers in the vitamin D pathway in prostate tissue
Cancer Causes and Control, 06/26/2012
Epstein MM et al. – Unlike circulating levels of 25(OH) vitamin D, expression levels of genes on the vitamin D pathway and vitamin D receptor (VDR) protein did not vary overall by season of tissue collection. Epidemiological analyses of vitamin D gene expression may not be biased by seasonality.
