Pituitary adenomas are neuroendocrine tumors that produce different endocrine and metabolic alterations, including hyperprolactinemia, acromegaly and Cushing's disease. These different clinical features of pituitary tumors are the result of the overproduction of hormones produced by the different pituitary cell types. Recent advances in the understanding of the signaling pathways that control hormone production in pituitary cells provide a source of potential therapeutic targets.

Corticotropin-releasing hormone (CRH) coordinates hormonal and behavioral responses to stress. The mitogen-activated protein kinase extracellular signal-related kinase 1/2 (ERK1/2) mediates several functions in different forebrain structures and recently has been implicated in CRH signaling in cultured cells. To study in vivo CRH-mediated activation of central ERK1/2, we investigated the expression pattern of the phosphorylated ERK1/2(p-ERK1/2) in the mouse brain after intracerebroventricular CRH injections.

An essential event in immune activation is the increase of cytokines in both plasma and immune tissues. Steroid hormones influence several adaptive responses in both health and disease. Cytokines and steroids have an intimate cross-communication in many systems, making possible a satisfactory adaptive response to environmental changes.
