In several cellular models of estrogen receptor function, 27-hydroxycholesterol, an endogenous selective modulator of estrogen receptors, exhibits notable partial agonist activity. In cell models of breast cancer, it actively controls transcription of genes and proliferation of cells [1]. By activating estrogen receptors, 27-hydroxycholesterol has a negative impact on prostate cancer cell lines. Estrogen receptor inhibitors can mitigate the considerable increase in cell proliferation caused by 27-hydroxycholesterol in LNCaP and PC3 cells [2]. Intracellular cholesterol homeostasis is regulated by 27-hydroxycholesterol, an oxysterol that is generated from cholesterol by the monooxygenase CYP27A1. In addition to its role as an endogenous selective estrogen receptor modulator, 27-hydroxycholesterol has the ability to promote the growth and spread of breast cancer. The tumor-promoting potential of CYP27A1 can be reduced by statins or direct inhibition of the enzyme, which lowers the levels of 27-hydroxycholesterol [3]. When there is an excess of cholesterol, one major route for LXR activation is the 27-hydroxylation of cholesterol [4].

| Additional Infomation |
(25R)-cholest-5-ene-3beta,26-diol is a 26-hydroxycholesterol in which the 25-position has R-configuration. It has a role as an apoptosis inducer, a neuroprotective agent, a human metabolite and a mouse metabolite. It is functionally related to a cholesterol.
27-Hydroxycholesterol is an endogenous metabolite of cholesterol produced by the hydroxylation of the carbon at position 27 by the enzyme sterol 26-hydroxylase, mitochondrial (CYP27A1). Some neoplasms produce excess of 27-hydroxycholesterol (27HC) or inhibit its catabolism, and high cholesterol levels are correlated with elevated levels of 27HC; under these conditions, 27HC may have deleterious selective estrogen receptor modulator (SERM) and liver X receptor (LXR) agonistic activities. As a SERM, 27HC binds to and prevents the activation of estrogen receptors (ERs) in the vasculature. This prevents ER-mediated vasodilation and abrogates the cardiovascular protective effects of estrogen. However, 27HC binds to and activates ERs and LXRs in breast tissue, which stimulates ER-dependent breast cancer cell growth and metastasis. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
