Drug-induced changes in the expression levels of β ₁ and α ₅ integrin subunits. Mean ± standard deviations of mean values of integrin subunit band intensities derived from 4 separate Western blotting experiments. Cells at 75% confluence were treated with low or high concentrations of valproate (A & B), thalidomide (C & D) or alcohol (E & F). Drug treatments in culture changed intensities of β₁ (left panels) and α₅ (right panels) integrin subunit bands. Drug concentrations and the time of exposures are shown below each bar. Symbols Controls (□), High (■) and Low drug () concentration. * p < 0.05.
