Phytosterols are widely present in vegetable oils, nuts, cereal products, fruits, and berries.
Phytosterol-induced treatment sensitivity has recently shed light on alleviating multidrug
resistance in cancer therapy. Here, we demonstrated that β-sitosterol, the most common
dietary phytosterol, recovers oxaliplatin (OXA) sensitivity in drug-resistant colorectal cancer
(CRC) cells by inhibiting breast cancer resistance protein (BCRP) expression. We further
showed evidence that β-sitosterol could activate p53 by disrupting the p53–MDM2 …
