The pictures illustrate the electrophoretic expression profiles of Cyclin B (A, MCF7 only) and Cdk1 (B) of A549 and MCF-7 cells exposed for 24 h to extracts #46, #29 and #32 (0.15%, v/v). Both panels indicate that this exposure increases the expression of Cyclic B and Cdk-1 proteins. Tubulin (B) and actin (A) have been used as loading controls, respectively.
