WebIntroduction. The continuous formation of new red blood cells (RBCs) is regulated by the glycoprotein hormone erythropoietin (EPO). Human EPO was first purified in 1977 from 2500 liters of urine from aplastic anemia patients, 1 and the nucleotide sequence of the human EPO cDNA was reported in 1985. 2,3 Since then, human EPO has become a …
WebIn these three conditions, we suggest that oxytocin stimulates prolactin secretion initiating an oxytocin-prolactin positive feedback loop. This positive feedback loop produces a sufficient amount of prolactin secretion to induce a dopamine-prolactin negative feedback loop, resulting in two independent loops with indirect interactions (Fig 7).
