Common_Name | 7a-Hydroxydehydroepiandrosterone |
Description | 7a-Hydroxydehydroepiandrosterone is a major metabolite of dehydroepiandrosterone (DHEA), which is is 7alpha-hydroxylated by the cytochrome P450 7B1 (EC 1.14.13.100, 25-hydroxycholesterol 7alpha-hydroxylase, CYP7B1) in the human brain and liver microsomes. Exposure to the proinflammatory cytokines TNFalpha, IL-1alpha, IL-1beta, and IL-17 increases CYP7B activity in synovial tissue. Increased CYP7B activity leads to higher levels of the DHEA metabolite 7alpha-OH-DHEA in synovial fluid, which may contribute to the maintenance of the chronic inflammation observed in rheumatoid arthritis patients. The glucocorticoid dhydrocorticosterone inhibits the conversion of DHEA to 7a-Hydroxydehydroepiandrosterone. The total levels of 7a-Hydroxydehydroepiandrosterone are increased in serum of patients with Alzheimer's disease. (PMID: 17467270, 15751070, 12667489, 9520908) |
