Vitamin D is currently associated with many diseases, not only bone health but also in autoimmune diseases, cancer, and neurological disorders. This study focuses on the mechanism relation vitamin D on breast cancer, especially with regard to estrogen receptor-positive (ER+) and human epidermal growth factor receptor 2-positive (HER 2+) cancers. Therapeutic supplementation is a commonly used approach to increase vitamin D levels. The effects of vitamin D have been investigated in various aspects, including regulation of cell growth and differentiation, apoptosis, intercellular contact, angioge

Background: Breast cancer is the most common malignancy in women in the world. Vitamin D helps control the majority of gene expression in female reproductive tissues. Body mass index (BMI) influences the bioavailability of vitamin D. Diet is one of the main sources of vitamin D and it is directly converted into 25-hydroxyvitamin D [25 (OH) D] in the liver.Objective: This study aimed to analyze the relationship between BMI and vitamin D intake and 25 (OH)D serum in patients with breast cancer.Method: Analytic observational with cross sectional design was used in this study.

Vitamin D deficiency is a potentially modifiable risk factor that may be targeted for breast cancer prevention and treatment. Preclinical studies support various antitumor effects of vitamin D in breast cancer. Numerous observational studies have reported an inverse association between vitamin D status, including circulating 25-hydroxyvitamin D (25(OH)D) levels, and breast cancer risk. The relationship between vitamin D and mammographic density, a strong predictor of breast cancer risk, remains unclear.

Abstract Postpartum breast involution is a physiologic inflammatory process that associates with increased risk of postpartum breast cancer (PPBC). In rodents, involution promotes breast cancer progression, and treatment with anti-inflammatory agents is protective.

Background/Objectives: Excess adiposity is associated with a higher risk of breast cancer metastasis and mortality. Evidence suggests that dietary vitamin D inhibits breast cancer metastasis. However, the mechanistic link between vitamin D’s regulation of adipocyte metabolism and metastasis has not been previously investigated. Therefore, the purpose of these experiments was to examine the effect of the active form of vitamin D, 1α,25-dihydroxyvitamin D (1,25(OH)2D), on adipocyte release of bioactive compounds and whether the impact on adipocytes leads to inhibition of breast cancer cell migra

Biologically active vitamin D (1,25-dihydroxycholecalciferol or 1,25(OH)2D) is synthetized from inactive prohormone 25-hydroxycholecalciferol (25(OH)D) by the enzyme CYP27B1 1-α-hydroxylase in kidney and several extrarenal tissues including breast. Although the development of breast cancer has been linked to inadequate vitamin D status, the importance of bioactive vitamin D production within tumors themselves is not fully understood. To investigate the role of tumoral vitamin D production in mammary epithelial cell progression to breast cancer, we conducted a Cre-loxP-mediated Cyp27b1 gene abl

Vitamin D regulates estrogen synthesis among other mechanisms involved in breast cancer (BC) development; however, no evidence has been found regarding its relationship with DNA repair capacity (DRC). Therefore, the objective of this study was to elucidate whether DRC levels are linked with plasma 25(OH)D levels. BC cases and controls were selected from our BC cohort. DRC levels were assessed in lymphocytes through the host-cell reactivation assay. 25(OH)D levels were measured using the UniCel DxI 600 Access Immunoassay System. BC cases (n = 91) showed higher 25(OH)D levels than the controls (

The active form of vitamin D3, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), is primarily known as a key regulator of calcium and phosphate homeostasis. It exerts its biological functions by binding to the vitamin D receptor (VDR), a transcription factor that regulates gene expression in vitamin D-target tissues such as intestine, kidney and bone. Yet, the VDR is expressed in many additional normal and cancerous tissues, where it moderates the antiproliferative, prodifferentiating and immune-modulating effects of 1,25(OH)2D3. Interestingly, several epidemiological studies show that low levels of 25(

Abstract Postpartum mammary gland involution is a physiologic inflammatory process that associates with increased risk of postpartum breast cancer (PPBC). Pre-clinical studies provide rationale for targeting this pro-tumor window of involution for PPBC prevention. However, the liver also undergoes physiological remodeling after weaning—consistent with weaning-induced mammary gland involution—which could potentially impact the efficacy of anti-cancer prodrugs administered during the postpartum period. Here, we used mouse models to test the efficacy of vitamin D, a prodrug with known anti-cancer

Breast cancer is the most common type of cancer in women worldwide. Statistics show breast cancer is the second leading cause of death after lung cancer. Vitamin D is believed to have anti-carcinogenic properties independently effective in protecting against breast cancer, biologically active vitamin D, can inhibit cell proliferation, induction of differentiation and apoptosis and inhibit angiogenesis in normal and malignant breast cells. Basal metabolic index (BMI) affects the bioavailability of vitamin D. Also the incidence of cancer increases with age, especially the age group> 40 years.
