Pituitary Actions of EGF on Gonadotropins, Growth Hormone, Prolactin and Somatolactins in Grass Carp

Biology, 2020
In mammals, epidermal growth factor (EGF) plays a vital role in both pituitary physiology and pathology. However, the functional role of EGF in the regulation of pituitary hormones has rarely reported in teleost.

Pituitary hormones are not required for sexual differentiation of male mice: phenotype of the T/ebp/Nkx2.1 null mutant mice.

Endocrinology, 2002
We have studied male sexual differentiation of null mutant mice (-/-) for the thyroid-specific enhancer-binding protein (T/ebp or Nkx2.1) gene, a homeodomain transcription factor that plays a role in organogenesis of the thyroid, lung, ventral forebrain,

ZBTB20 is required for anterior pituitary development and lactotrope specification

Nature Communications, 2016
The pituitary is a complex structure with the anterior lobe containing five specialized cell types secreting different hormones. Here Cao et al. unravel a role for ZBTB20 in pituitary development and specifically in lactrotrope specification.
