GPR150 and ovarian cancer: Novel predicted chief cell-enriched genes included the orphan receptor GPR150, a G-protein coupled receptor in which aberrant methylation has been linked to ovarian cancer [61]; MOGAT1, a monoacylglycerol acyltransferase that functions in the absorption of dietary fat in the intestine [62]; and LIPK, previously identified in the epidermis with a function in lipid metabolism [63].
