Expression of Plk2, Plk3 and Plk4 protein levels are regulated during cardiac myocyte development.

<p>Ventricular cardiac myocytes were isolated from hearts at various stages of development (embryonic day 18 [E18], 2, 5 and 10 days postnatal [P2, P5 and P10] and adult [250 g males]) and assessed for Plk2, Plk3 and Plk4 protein expression (A, C and E, respectively, black bars). Samples were normalised to GAPDH. Each bar chart represents data from at least 3 separate experiments, * p<0.05. Representative blots are shown for Plk2 (B), Plk3 ((D) and Plk4 (F).
