To link to the content of EndoNet use the EndoNet ID that is given on the detail
pages in the format ENX0000, where X is a place holder for the type of
the component (e. g. R for receptor or C for anatomical structure).
As URL
for the linking append this ID to the detail page for this type of component.
For an hormone that would be:
http://endonet.bioinf.med.uni-goettingen.de/hormone/ENH00000
It is also possible to use the search of EndoNet to link to the right detail page. The URL should look like

Synonyms
adrenal medulla, medulla of suprarenal gland, suprarenal medulla, medulla of adrenal gland, Medulla glandulae suprarenalisGeneral information
The internal part of the suprarenal gland which contains masses of chromaffin cells filled with venous sinusoids; it is composed principally of anastomosing cords of cells in the core of the gland; the cells display a chromaffine reaction because of the presence of epinephrine and norepinephrine in their granulesLinks to other resources

Receptor: BMP receptor type II
Induced phenotype:
- regulation of cell fate specification
- In addition to the developmental context, BMPs secreted locally by the adrenal cortex are good candidates that could also modify the cellular fate of tissue progenitor cells in the adult adrenal medulla. [4]
- negative regulation of catecholamine biosynthetic process
- BMPs have the potential to influence aldosterone-dependent dopamine production. [5]
- BMPs are thought to influence catecholamine production of adrenomedullary cells via an indirect mechanism through interfering with steroid hormone-dependent signalling pathways. [6]
- BMPs can inhibit dopamine expression and reduced DOPA decarboxylase mRNA expression in a dose-dependent manner, thereby acting antagonistic to glucocorticoids. [6]
- regulation of cell fate specification
-
Receptor: BMP receptor type IB
Induced phenotype:
- positive regulation of adrenal development
- The introduction of a constitutively active type I BMP receptor in neural crest cells is sufficient to induce the development of adrenergic cells. [7]
- Reduction of BMP-4-induced signalling is assiciated with smaller adrenal size in sheep. [8]
- BMP is important for regulation of adrenal development, specially of adrenomedullary cell specification from neural crest. [4]
- positive regulation of adrenal development

Receptor: VPAC2
Influences:
- ACTH
- There is proof that VIP and PACAP can also enhance aldosterone secretion indirectly, by eliciting the release from medullary chromaffin cells of catecholamines and adrenocorticotropic hormone, which in turn may act on the cortical cells in a paracrine manner. [1]
