Figure 6 (A) Western blots indicating the translocation of protein kinase C (PKC) isoforms  and  into the particular fraction. Cells were incubated for 5 min (control, C), with norepinephrine (NOR, 1 µmol/liter) or norepinephrine and atenolol (NOR + Ate, 1 µmol/liter). (B) Incorporation of 14C-phenylalanine (Phe) of cardiomyocytes cultured for 24 h in presence of phenylephrine (PE, 10 µmol/liter), phorbol myristate acetate (PMA, 0.1 µmol/liter), or PE and PMA in co-presence of isoprenaline (1 µmol/liter) and ICI 118,551 (ICI, 0.1 µmol/liter) (ISO + ICI). Data are expressed as percentages relative to the control values. Data are means ± SEM from n = 6 cultures. * = p < 0.05 vs. each other.
