The two regulatory subunits (R1 and R2) of PKA are differentially expressed in several cancer cell lines and studies indicate distinct roles for these subunits in growth control. Recently, mutations of the regulatory subunit 1A of PKA gene have been identified in patients with Carney complex (CNC). The aim of this study was to evaluate the expression of the different PKA regulatory subunits (R1A, R2A, R2B) in adrenocortical tumors not associated with CNC, as well as the effect...

In our previous investigation on microRNAs expression pattern in parathyroid carcinomas (Ca), we detected the over-expression of microRNAs belonging to C19MC, the largest human cluster on chromosome 19q13.41. In the present study, the analysis of the expression of selected C19MC and the closely distal MIR371-3 clusters microRNAs (MIR512-3p, MIR517C, MIR520H and MIR372) was extended to 11 Ca, 24 adenomas (Ad) and 6 normal glands. The four microRNAs was expressed in 11% of parat...

Introduction: MEN1 is characterized by tumors of parathyroid glands, pituitary and pancreas. Pituitary tumors frequently produce PRL and GH, but acromegaly due to ectopic GHRH secretion has been reported in <1% of cases. Here we present a case of two patients belonging to a MEN1 family (c.207delC; p.P69PfsX118 mutation (ENST00000377313), affected by primary hyperparathyroidism, in association with acromegaly due to ectopic GHRH secretion and bronchial carcinoid, respective...
