生物活性

Cholesterol myristate is a natural steroid present in traditional Chinese medicine. Cholesterol myristate binds to several ion channels such as the nicotinic acetylcholine receptor, GABAA receptor, and the inward-rectifier potassium ion channel.

体外研究
(In Vitro)

Mesenchymal stem cells (MSCs) transfected by the Id1 promoter reporter construct, cholesterol myristate increases the activity of Id1 promoter. Cholesterol myristate inhibits the apoptosis of MSCs induced by serum-free. Cholesterol myristate increases the expression of Id1 and its target gene bcl-x/l in MSCs treated with serum-free. Moreover, noggin, a BMP antagonist, reduces the anti-apoptotic effects of cholesterol myristate[1]. Cholesterol myristate inhibits the apoptosis of PC12 cells induced in serum-free condition. Cholesterol myristate significantly increases the expression of BMP4, BMPRIA, p-Smad1/5/8, Id1 and its antiapoptotic target gene Bcl-xL in PC12 cells treated in serum-free condition[1].

Cell Assay
[1]

MSCs are cultured with or without serum in 96-well plates and treated with cholesterol myristate in various concentrations (0, 30 and 300 μg/mL) for 3 days. Each sample is repeated in five independent wells and is incubated for 72 h. After incubation, 20 μL MTT (5 mg/mL) is added and the culture is incubated for a further 4 h. The culture medium is discarded and replaced with 150 μL DMSO. The absorbance at 490nm is measured[1].
