CART1 peptide is expressed in the caudal and cephalic lobes of chicken anterior pituitary.
CRH potently stimulates pituitary CART1 expression in chickens.
Both cCRHR1 and cCRHR2 are functional and co-expressed in chicken pituitary.
cCRH action on cCART1 expression is mediated by cCRHR1 expressed on corticotrophs.
Multiple signaling pathways coupled to CRHR1 mediate CRH-induced CART1 expression.
