Monoacylglycerol lipase ABHD2 Enhanced neointimal hyperplasia was observed in Abhd2-deficient mice, using an experimental vascular cuff placement injury model. Abhd2 is expressed in vascular smooth muscle cells (SMCs). An association between the human ABHD2 gene and colorectal cancer and with Risks for Chronic Obstructive Pulmonary Disease is reported. ABHD2 is a steroid-activated (progesterone P4) enzyme that hydrolyzes 2-arachidonoylglycerol. ABHD2 is expressed in sperm and in ovaries
