Identification of gap junctional connexin-32 mRNA and protein in gonadotropin-releasing hormone neurons of the female rat.

abstract：BACKGROUND:Type I gastric carcinoids (TIGCs) are neuroendocrine neoplasms arising from enterochromaffin-like cells in atrophic body gastritis. Data regarding their evolution in prospective series are scarce, thus treatment and follow-up are not codified. Our aim was to evaluate clinical outcome and recurrence in TIGCs ...
