Regulatory mechanisms and pathological implications of CYP24A1 in Vitamin D metabolism

CYP24A1 is a crucial gene within the cytochrome P450 superfamily, responsible for encoding the enzyme 25-hydroxyvitamin D3–24-hydroxylase. This enzyme is involved in the catabolism of 1,25-dihydroxyvitamin D3, the biologically active form of vitamin D3, by hydroxylating its side chain. Through this...

Description
Summary:CYP24A1 is a crucial gene within the cytochrome P450 superfamily, responsible for encoding the enzyme 25-hydroxyvitamin D3–24-hydroxylase. This enzyme is involved in the catabolism of 1,25-dihydroxyvitamin D3, the biologically active form of vitamin D3, by hydroxylating its side chain. Through this process, CYP24A1 tightly regulates the bioavailability and physiological impact of vitamin D3 in the body. Dysregulation of CYP24A1, particularly its overexpression, has been increasingly associated with the progression of various diseases, including cancers, autoimmune disorders, and chronic inflammatory conditions. Elevated levels of CYP24A1 can lead to excessive degradation of vitamin D3, resulting in diminished levels of this critical hormone, which is essential for calcium homeostasis, immune function, and cellular proliferation. This review explores into the structural characteristics of CYP24A1, exploring how it influences its enzymatic activity. Furthermore, it examines the expression patterns of CYP24A1 across different diseases, emphasizing the enzyme's role in disease pathology. The review also discusses the regulatory mechanisms governing CYP24A1 expression, including genetic mutations, epigenetic modifications, and metabolite-mediated regulation. By understanding these mechanisms, the review provides insight into the potential therapeutic strategies that could target CYP24A1, aiming to alleviate its overexpression and restore vitamin D3 balance in disease states.
