Assessment the effect of vitamin D supplementation on plasma vitamin D levels, inflammatory and antioxidant biomarkers and factors associated with cell proliferation, differentiation, damage and appopotosis in breast cancer survivor

Protocol summary

Summary
This is an interventional study which will assess the effect of vitamin D supplementation on plasma vitamin D levels, inflammatory and antioxidant biomarkers and factors associated with cell proliferation, differentiation, damage and apoptosis in breast cancer survivor based on polymorphisms in vitamin D receptor (VDR) gene. Present study will be conducted on breast cancer survivor referring to Shohadaye Tajrish hospital and its associated clinics. One hundred sixty-five breast cancer survivor will receive 4000 IU of vitamin D3 daily for 12 weeks. VDR Fok1, Apa I, TaqI, BsmI and Cdx-2 genotypes will be determined at the end of the study and responses to vitamin D supplement e.g. inflammatory, antioxidant, cell proliferation, differentiation, damage and apoptosis will be compared between three subgroups of each VDR polymorphisms.
