Baicalein, 5,6,7-Trihydroxyflavone, isolated from Scutellaria baicalensis and Scutellaria lateriflora (71), holds potential in treating breast cancer (72), colorectal cancer (73), bladder cancer (74), etc. Baicalein may reverse ABCB1 mediated MDR as shown on ABCB1 gene transfected Madin-Darby canine kidney II (MDCK II) cells (75). This evidence concerns the gene ABCB1 and breast carcinoma.
