Neuroendocrine Consequences of Hypothalamic Hamartoma and their Imaging (MRI) and Surgery Correlates

Corredor Beatriz , Caredda Elisabetta , Ederies Ash , Tisdall Martin , Cross Helen , Spoudeas Helen A.

Background: Hypothalamic hamartomas(HH) are rare heterotopic congenital malformations causing central precocious puberty(CPP) and/or resistant epilepsy whose natural history is unknown.Aim: To describe clinical and imaging features, and the risk of developing endocrine deficits, particularly after surgery.Method: Retrospective case note and imaging review of all HH diagnosed by MRI between 30.08.1991 and 24.11.17, analysed by initi...

Understanding the molecular basis of short stature in Fanconi Anemia: Impact of pappalysins and stanniocalcins on IGF-I bioavailability

Corredor Beatriz , Martín Alvaro , Zubicaray Josune , Sevilla Julián , Barrios Vicente , Argente Jesús

Introduction: The stanniocalcins (STCs) are inhibitory factors of the growth-promoting effects of IGFs through inactivation of pappalysins that favor the release of IGFs from their binding proteins (IGFBPs). STC1 can be involved in the cellular response to stress and plays an important role in cell cycle regulation. Patients with Fanconi Anemia (FA) are more sensitive to oxidative stress that could alter the expression of STC1. Our aim was to assess whether pa...

Are pappalysins and stanniocalcins involved in modifying the bioavailability of IGF-I in children with onset of type 1 diabetes mellitus?

Güemes Maria , Canelles Sandra , Martín-Rivada Álvaro , Corredor Beatriz , Barrios Vicente , Argente Jesús

Introduction: Both poor and optimal metabolic control of type 1 diabetes mellitus (T1DM) in children can impact longitudinal growth. A decrease in insulin-like growth factor (IGF)-I and its binding protein 3 (IGFBP3) has been described in these patients. New growth regulatory factors [pappalysins (PAPP-As) and stanniocalcins (STCs)] could modulate the bioavailability of IGFs by regulating the concentrations of intact and free IGFBPs.<str...
