2013, Current Topics in Developmental BiologyCitation Excerpt :These findings support the hypothesis that the competence of tadpole pituitary thyrotropes to respond to hypothalamic CRF depends on the upregulation of the CRF2 receptor during late prometamorphosis. Negative feedback by TH on the hypothalamus and pituitary plays a central role in thyroid homeostasis in all adult vertebrates that have been studied including frogs (Fig. 7.1; Jacobs & Kuhn, 1992; Kaneko et al., 2005). The discovery of a sustained rise in TSH production and thyroid activity during tadpole metamorphosis led Etkin (1968) to hypothesize that negative feedback on pituitary TSH does not develop until metamorphic climax.
