Immunoblot analysis of tumour suppressor proteins p53 and p21 in cell lysates of a MCF-7 on treatment with TBBE (150 µg/ml) and TBWE (150 µg/ml), b HeLa on treatment with TBBE (150 µg/ml) and TBWE (150 µg/ml) and c U87 when treated with TBEE (100 µg/ml), TBBE (50 µg/ml) and TBWE (50 µg/ml). β-actin (43 kDa) served as loading control. Relative densities of the blots are mentioned below to express the expression intensities
