LKB1IP promotes pathological cardiac hypertrophy by targeting PTEN/Akt signalling pathway.

ABSTRACT: Pathological cardiac hypertrophy represents a leading cause of morbidity and mortality worldwide. Liver kinase B1 interacting protein 1 (LKB1IP) was identified as the binding protein of tumour suppressor LKB1. However, the role of LKB1IP in the development of pathological cardiac hypertrophy has not been explored. The aim of this study was to investigate the function of LKB1IP in cardiac hypertrophy in response to hypertrophic stimuli. We investigated the cardiac level of LKB1IP in samples from patients with heart failure and mice with cardiac hypertrophy induced by isoproterenol (ISO) or transverse aortic constriction (TAC). LKB1IP knockout mice were generated and challenged with ISO injection or TAC surgery. Cardiac function, hypertrophy and fibrosis were then examined. LKB1IP expression
