Key result
Adenovirus-mediated overexpression of DGK-zeta in cardiomyocytes significantly blocked ET-1-induced activation of the PKC-epsilon-ERK-AP1 signaling pathway and resultant hypertrophy (P<0.01).
Why the study?
Does adenovirus-mediated overexpression of DGK-zeta inhibit ET-1-induced cardiomyocyte hypertrophy?
Does adenovirus-mediated overexpression of DGK-zeta inhibit ET-1-induced cardiomyocyte hypertrophy?
p-value: p=<0.01
Overexpression of DGK-zeta inhibits ET-1-induced cardiomyocyte hypertrophy by blocking the PKC-epsilon-ERK-AP1 signaling pathway, suggesting it acts as a negative regulator of the hypertrophic program.

Should not yet influence clinical management; hypothesis-generating for DGK-zeta in hypertrophic signaling.
Takahashi et al. (2005) studied Cardiomyocyte hypertrophy. Adenovirus-mediated overexpression of DGK-zeta (Ad-DGKzeta) vs. Endothelin-1 (ET-1) alone was evaluated on ET-1-induced translocation of PKC-epsilon (p=<0.01). Adenovirus-mediated overexpression of DGK-zeta in cardiomyocytes significantly blocked ET-1-induced activation of the PKC-epsilon-ERK-AP1 signaling pathway and resultant hypertrophy (P<0.01).
