Effect of okadaic acid on nuclear localization of basonuclin. Keratinocytes growing in KGM medium on a glass coverslip without 3T3 support were treated with 1 μM okadaic acid in 0.1% dimethyl sulfoxide (final concentration) for 1 hr. The control culture contained the same concentration of dimethyl sulfoxide alone. Keratinocytes were stained for basonuclin (red) and for DNA with Hoechst (blue).
