Retinol as cofactor in the oxidative activation of PKCα. Normalized results of immunoprecipitation/kinase assays of six independent titrations of H₂O₂ with retinol (Rol)-depleted (white bars) and retinol-reconstituted (black bars) 3T3 fibroblasts. Except for unstimulated cells, the evaluation by Student's t test showed significantly higher PKC kinase activity in retinol-reconstituted cultures for each H₂O₂ concentration compared with retinol-deficient cultures (P < 0.001).
