JAK2/STAT5 is the principal growth hormone (GH) signaling pathway related to body growth. It is positively regulated by glucocorticoid receptor (GR) and hepatocyte nuclear factor 1 (HNF-1) and downregulated by activation of tyrosine-phosphatases SHP-1,-2 and PTP-1B, and by GH-induction of suppressors of cytokine signaling (CIS/SOCS) that block GHR or JAK2, and promote internalization/degradation of signaling complexes. This pathway is desensitized in liver of adult transgenic ...

Wnt/beta-catenin signalling pathway is required during embryonic development for normal cell proliferation, differentiation and for organ homeostasis in adulthood. Over-activation of this pathway has been implicated in human cancers such as colon or skin cancers. Here, we demonstrate that enhancement of the Wnt pathway in the embryonic Rathke’s pouch causes over-proliferation of progenitor cells and severe differentiation defects in the Pit1-lineage, which results ...

Background: SOX2 is a member of the SOX family of transcription factors (SRY-related high-mobility group (HMG) box). Heterozygous, de novo, loss-of-function mutations were initially reported in patients with bilateral anophthalmia/microphthalmia, developmental delay, male genital tract abnormalities, oesophageal atresia and sensorineural hearing loss. We have recently reported a number of SOX2 mutations in patients with anterior pituitary hypoplasia and hy...

TSH-secreting pituitary adenomas (thyrotropinomas or TSH-omas) are rare. At diagnosis, TSH-omas are frequently macroadenomas presenting with variable symptoms, and signs of hyperthyroidism. Somatostatin analogs (SSA) are a very efficient treatment to improve clinical signs in patients with TSH-omas, reducing hormone levels (90%) and causing tumor shrinkage (50%).Inhibitory effects of SSA are mediated by a family of five somatostatin receptor subtypes (sst1-5), with sst2 and ss...

Objective: To evaluate the results of laparoscopic adrenalectomy in our institutions.Methods: Prospectively collected data from 2000 to 2007.Results: During the 8-year study period, 160 laparoscopic adrenalectomies were performed in 150 patients. Mean age was 49.8 years (female: 60.7%). Twenty-seven patients (18%) had previous open abdominal operations. There were 10 bilateral (6.6%) for Cushing’s disease, 64 right (42.7%) and...

Objective: To evaluate the main clinical characteristics and the obstetrical results of perinatal morbi-mortality of women with gestacional diabetes in our Service.Material and method: We made a descriptive study of 83 gestational diabetes patients which became a pursuit coordinated between the services of Endocrinology and Gynecology. The following main aspects were analyzed: age, toxic habits, BMI pre-gestational, first pregnancy or not, previous antec...

Objectives: To verify the results of the insulin treatment intensification in the control of Diabetes Mellitus type 1 and 2 (DM1 and DM2).Methodology: Of 100 diabetic patients (30% DM1 and 70%DM2) derived to Day Diabetes Hospital (DDH) by glycemic decompensation during year 2007 were studied, 45% women and 55% men (we excluded the debut). The average age of the patients was of 35.1 years in DM1 and 64.4 years in DM2. The Hba1c in the first visit and to t...

Background and aims: CXC chemokine ligand 10 (CXCL10) also known as chemokine interferon γ inducible protein (IP-10) is a CXCR3 chemokine belongs to a group of structurally related molecules, that induce the chemotaxis of diverse leukocyte subtypes including activated T-helper 1 lymphocytes, natural killer cells and monocytes. In patients with Hashimoto’s thyroiditis, type 1 diabetes mellitus and Graves’ disease high levels of CXCL10 ligand in serum have been fo...
