Vitamin D as a promising anticancer agent

Area of Science:

• Oncology
• Molecular Biology
• Nutritional Science

Background:

• Vitamin D receptors are present in noncalcemic tissues.
• Vitamin D influences growth factor-mediated cellular functions.
• Potential role of vitamin D in cancer genesis, progression, and survival is suggested.

Purpose of the Study:

• To evaluate the potential of vitamin D in cancer prevention and regression.
• To investigate the mechanisms by which vitamin D affects cancer cells.
• To explore vitamin D's role as an adjuvant in cancer therapy.

Main Methods:

• In vitro and in vivo studies were conducted.
• Analysis of vitamin D's interference with growth factor receptor signaling pathways (receptor tyrosine kinases).
• Assessment of vitamin D's effect on gene expression, cell proliferation, angiogenesis, differentiation, and apoptosis.

Main Results:

• Optimistic data regarding vitamin D's potential in preventing and regressing colorectal, prostate, and breast cancers.
• Vitamin D interferes with receptor tyrosine kinase pathways, modulating transcription and genomic functions.
• Vitamin D inhibits cell proliferation and angiogenesis, while facilitating cell differentiation and apoptosis.
• Vitamin D upregulates cystatin D, an endogenous protein with antitumor and antimetastatic properties.

Conclusions:

• Vitamin D demonstrates significant potential in cancer prevention and as an adjuvant in cancer treatment.
• Its mechanisms involve modulating key cellular pathways, inhibiting tumor growth, and promoting cell death.
• Further research supports its inclusion in combination chemotherapy regimens for various cancers.
