Beta-Sitosterol

Research use only, not for human use.

β-Sitosterol has recently been shown to induce G2/M arrest, endoreduplication, and apoptosis through the Bcl-2 and PI3K/Akt signaling pathways.

β-Sitosterol has recently been shown to induce G2/M arrest, endoreduplication, and apoptosis through the Bcl-2 and PI3K/Akt signaling pathways. β-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Although the exact mechanism of action of β-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). β-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells.(In Vitro):Beta-Sitosterol is one of the most abundant dietary phytosterols. Beta-Sitosterol shows anticancer properties against breast cancer, prostate cancer, colon cancer, lung cancer, stomach cancer, ovarian cancer, and leukemia.

Cell Cytotoxicity Assay Cell Line:MDA-MB-231 Concentration:16 μM Incubation Time:3 days Result:No cytotoxicity at 16 μM Apoptosis Analysis Cell Line:MDA-MB-231 Concentration:16 μM Incubation Time:5 days Result:Increased 33% apoptosis when assayed using 1×104 cells and a 6-fold increase in apoptosis when assayed using a smaller number of cells 5×103.Western Blot Analysis Cell Line:COLO 320 DM Concentration:15, 30, 60, 120 μM Incubation Time:24 h Result:Decreased β-catenin and PCNA expression.
