Pituitary gonadotropes (LH and FSH producing cells) are simultaneously exposed to numerous stimuli, which exert multiple signalling pathways that cross-talk with the GnRH receptor (GnRHR). A model downstream effector system is the prostanoid family. Hence, prostanoid receptors and GnRHR might cross-talk and affect the biological responses of the gonadotropes. Here we report the expression of prostaglandin (PG) PGE2 receptors EP1, EP2, EP3 and EP4, the PGF2</sub...

The pituitary-expressed growth hormone 1 gene was screened for mutation in a group of 74 Spanish children with familial short stature resulting in the identification of a novel Ile179Met missense mutation. Variant and wild-type GH were expressed in insect cells and functional studies were performed. The Ile179Met variant was shown to exhibit a similar degree of resistance to proteolysis as wild-type GH, indicating that the introduction of Met does not cause significant ...
