Cardiotrophin-1 (CT-1) is aprotein encoded by theCTF1gene in humans. It functions as acytokine and acts as a 21.5 kDa cardiac hypertrophic factor. CT-1 belongs to theIL-6 cytokine family.

CT-1 is highly expressed in the heart, skeletal muscle, prostate and ovary and to lower levels in lung, kidney, pancreas, thymus, testis and small intestine.^[5]

The protein exerts its cellular effects by interacting with theglycoprotein 130 (gp130)/leukemia inhibitory factor receptor beta (LIFR) heterodimer. In addition, CT-1 activatesphosphatidylinositol 3-kinase (PI-3 kinase) incardiac myocytes and enhances transcription factorNF-κB DNA -binding activities.

CT-1 is associated with the pathophysiology ofheart diseases, including hypertension, myocardial infarction, valvular heart disease, and congestive heart failure.
