Interactions of aromatase and seladin-1: A neurosteroidogenic and gender perspective

Aromatase and seladin-1 are enzymes that have major roles in estrogen synthesis and are important in both brain physiology and pathology. Aromatase is the key enzyme that catalyzes estrogen biosynthesis from androgen precursors and regulates the brain’s neurosteroidogenic activity. Seladin-1 is the...

Interactions of aromatase and seladin-1: A neurosteroidogenic and gender perspective
