The regulation of CTRP9 was analyzed, its levels of plasma were found to be reduced in myocardial ischemia-reperfusion injuring in addition to a decrease in CTRP9 expression in fat tissue, while an increase in plasma free fatty acid was noticed as well as an increase in the expression of NADPH in fat tissue. The gene discussed is C1QTNF9; the disease is myocardial ischemia.
