Key result
MCIP1 knockout exacerbated the hypertrophic response to activated calcineurin but blunted cardiac hypertrophy in response to pressure overload or chronic adrenergic stimulation.

Should not inform clinical practice; leaves open stimulus-dependent MCIP1 roles in hypertrophy models.
Does genetic deletion of MCIP1 alter the cardiac hypertrophic response to stress stimuli in mice?
MCIP1 has dual roles in cardiac hypertrophy, acting to either facilitate or suppress calcineurin signaling depending on the specific hypertrophic stimulus.
Vega et al. (2003) studied Cardiac hypertrophy. MCIP1 knockout vs. Wild-type/baseline was evaluated on Cardiac hypertrophic response to stress stimuli. MCIP1 knockout exacerbated the hypertrophic response to activated calcineurin but blunted cardiac hypertrophy in response to pressure overload or chronic adrenergic stimulation.
