Effects of kappa-opioid receptor stimulation on high glucose induced myocardial hypertrophy of neonatal rats / 中国应用生理学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of kappa-opioid receptor stimulation on high glucose induced myocardial hypertrophy of neonatal rats.</p><p><b>METHODS</b>Using cultured myocardial cells as a model, the protein content was assayed with Lowrys method. The cardiomyocytes volumes were measured by computer photograph analysis system. The level of p-ERK44/42 was determined by Western blot.</p><p><b>RESULTS</b>Compared with the control, U50488H significantly inhibited the protein content and volumes of cultured hypertrophic myocardial cells induced by high glucose. Meanwhile the role of ERK was important.</p><p><b>CONCLUSION</b>The stimulation of kappa-opioid can inhibit myocardial hypertrophy induced by high glucose, which is possibly via attenuating p-ERK.</p>
