From: Biosynthesis and release of pheromonal bile salts in mature male sea lamprey
Schematic of sexually mature male sea lamprey showing tissue-specific bile salt distribution and release. Bile salts are shown in order of most abundant (bold font) to least abundant, and include: 3-keto petromyzonol sulfate (3kPZS), 3-keto allocholic acid (3kACA), petromyzonol sulfate (PZS), allocholic acid (ACA), and petromyzonamine disulfate (PADS). Genes examined that encode for enzymes associated with biosynthesis and transport of bile salts are shown in the respective tissues where they were greatest expressed, and include: cyp7a1, cyp27a1, cyp8b1, bsep, and slc10a1 greatest expressed in liver tissue, and hsd3b7, sult2a1, sult2b1 and slc10a2 greatest expressed in the gill.
