Beta-sitosterol is one of the main dietary phytosterols found in plants which have a similar skeleton as cholesterol. In human clinical trials, beta-sitosterol has been shown to have cholesterol-lowering effects and to relieve symptoms of benign prostatic hyperplasia. There has been a large amount of basic research conducted for potential applications of beta-sitosterol in a diverse range of conditions including cervical cancer, breast cancer, cystic fibrosis, and others. Beta-sitosterol is available over the counter as a natural health supplement and is marketed for a wide range of applications including headaches, tuberculosis, allergies, cancers, fibromyalgia, lupus, asthma, hair loss and many others.

Sample Use Guides

In Vivo Use Guide

Over 6 to 8 weeks beta-sitosterol supplementation of 12 g/day resulted in an average of 11% decrease in serum cholesterol and a 12% decrease in biliary cholesterol saturation.

Route of Administration: Oral

In Vitro Use Guide

Human cervical cancer cell lines, Caski and HeLa, were cultured in RPMI-1640 and supplemented with 10% foetal bovine serum and incubated at 37 deg-c in an atmosphere with 5% CO2. Cells were treated with 20 umol/L of beta-sitosterol for 48 hours and examined for changes by light microscopy, electron microscopy, and transmission electron microscopy. Changes in mRNA and protein expression were quantified using Real-Time qPCR and western blots. The treatment with beta-sitosterol reduced expression of PCNA, increased p53 mRNA, decreased the amount of HPV E6 transcripts. Cells treated with beta-sitosterol also exhibited loss of cell surface microvilli and increased electron density in the cell membrane.
