Oral glucose tolerance test vs fasting plasma glucose determination for the assessment of glucose metabolism disturbances in women with Polycystic Ovary Syndrome

Ortiz Andres , Fernandez Elena , Alvarez Francisco , Santacruz Elisa , Rosillo Marta , Escobar Hector , Luque Manuel

Background: Polycystic ovary syndrome (PCOS) is a common endocrine condition in women at reproductive age, in whom, glucose metabolism disturbances are commonly observed. In addition, overweight and obesity, especially visceral obesity, are more prevalent in PCOS women, which enhances the resistance to insulin action, and as consequence, the onset of impaired glucose tolerance (IGT) and/or type 2 diabetes mellitus (T2DM). Clinical guidelines recommend oral glucose tolerance te...

Ectopic cushing’s syndrome: Report of 5 cases from a tertiary care center

Pascual-Corrales Eider , Pinedo Marta Marchan , Maria Fernandez Argüeso , Manuel Luque-Ramírez , Castro Marta Araujo

IntroductionEctopic Cushing’s syndrome (ECS) is a rare entity caused by ACTH secretion by a non-pituitary tumor. The management of these patients is challenging due to its low frequency and limited experienced. The objective of this study was to describe the patients with ECS treated in the Division of Endocrinology at the Ramón y Cajal University Hospital (Madrid, Spain) in the last six years.Methods<p class="abstext...

Splicing dysregulation is associated with aggresive and metabolic-associated liver disease-derived hepatocellular carcinoma

Sanchez Natalia Herman , Lopez-Canovas Juan L , del Rio-Morenos Mercedes , Amado Victor , de la Mata Manuel , Rodriguez-Peralvarez Manuel , Luque Raul M , Gahete Manuel D

Metabolic-associated fatty liver disease (MAFLD) is a growing cause of hepatocellular carcinoma (HCC), but the molecular mechanisms associated with the pathological progression from MAFLD to HCC are still to be fully elucidated. The genomic and transcriptomic profile of HCC samples have been widely described; however, the proteomic landscape of MAFLD-derived HCC samples is mostly unknown. Here, we sought to perform the first quantitative proteomic analysis of HCC samples from ...

Neuronostatin receptor GPR107 as a potential biomarker and therapeutic target in chronic liver disease

Garcia-Estrada Antonio , Herman-Sanchez Natalia , Lopez-Canovas Juan Luis , Saez-Martinez Prudencio , Zamora-Olaya Javier M , Rodriguez-Peralvarez Manuel , Luque Raul M , Gahete Manuel D.

Metabolic associated fatty liver disease (MAFLD) is rapidly becoming a major aetiology for the development of hepatocellular carcinoma (HCC, the most common liver cancer) in the context of chronic liver disease. Current therapeutical options for MAFLD (dietetic/lifestyle intervention and/or pharmacological approaches) are still insufficient and the cellular and molecular mechanisms underlying this disease are yet to be fully understood. Our group previously reported that the n...

Aminoacyl-tRNA synthetases as diagnostic, prognostic, and therapeutic tools in MAFLD-derived hepatocellular carcinoma

Herman-Sanchez Natalia , Lopez-Canovas Juan L. , Amado Victor , Zamora-Olaya Javier M , Rodriguez-Peralvarez Manuel , Luque Raul M , D. Gahete Manuel

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a growing cause of hepatocellular carcinoma (HCCs); however, the molecular characteristics of MAFLD-derived HCCs are still to be elucidated. To provide novel insights in this field, we performed the first quantitative proteomic analysis of HCC samples from different aetiologies. Particularly, cytosolic and nuclear proteome of liver tissues from HCC patients (n=42; HCC vs adjacent tissue) and healthy contr...

Associations between radiological parameters and molecular phenotype in human GH-secreting pituitary tumours: could they help in predicting the appropriate medical therapy?

Alhambra-Exposito Maria Rosa , Lombardo-Galera Maria Sagrario , Ibanez-Costa Alejandro , Rivero-Cortes Esther , Gahete Manuel , Luque-Huertas Raul , Galvez-Moreno Maria Angeles , Castano-Pastor Justo

Acromegaly is caused by excessive GH secretion from pituitary adenomas. Transphenoidal surgery is the first-choice treatment, but new drug therapies (e.g. somatostatin analogues, SSA) offer promising avenues for medical treatment. Complementary diagnostic tools may assist this strategy, helping to refine drug choice. Here, we investigate the associations between radiological features and molecular phenotype of pituitary tumours from acromegalic patients. This observational stu...

Characterization of the somatostatin and ghrelin hormonal systems revealed their potential therapeutic role in chronic liver disease

Herman Sanchez Natalia , Luis Lopez-Canovas Juan , Garcia-Estrada Antonio , Saez-Martinez Prudencio , Amado Victor , de la Mata Manuel , Cordoba-Chacon Jose , Sarmento-Cabral Andra , Rodriguez-Peralvarez Manuel , Luque Raul M. , Gahete Manuel D.

Hormonal signalling plays a key role in the progression of metabolic (dysfunction)-associated fatty liver disease (MAFLD) to hepatocellular carcinoma (HCC). However, the role of somatostatin (SST), cortistatin (CORT), neuronostatin (NST) and ghrelin systems in MAFLD-HCC progression has not yet been elucidated. We characterized the role of SST/CORT/NST and ghrelin systems in chronic liver disease and evaluated their clinical potential. The expression of the components of the SS...

Introduction: The incidence of papillary thyroid microcarcinomas (MPT, max diameter≤10 mm) has increased in recent years. Most have a very good prognosis but some have growth during follow-up, lymph node and / or distant metastases.Material and methods: We performed a single-center, retrospective cohort study, n=114 patients (86% women, average age 48.3 years), diagnosed with MPT between 1998 and 2012. Risk stratification system (ATA 2015): 10 high...

Utility of In1-ghrelin as a novel non-invasive diagnostic and prognostic biomarker of prostate cancer in patients with PSA in the grey-zone

Montero-Hidalgo Antonio J. , Herrero-Aguayo Antonio J. , Enrique Gómez-Gómez , Guler Ipek , Justo P. Castaño , Sarmento-Cabral André , Gahete Ortiz Manuel , Luque Raul M , Jiménez Vacas Juan Manuel

Prostate cancer (PCa) is one of the leading causes of cancer deaths among men population worldwide. This tumour pathology is commonly diagnosed through the determination of serum PSA levels. However, the diagnostic capability of PSA dramatically drops when considering patients with PSA levels lower than 10 ng/ml, the so-called “grey-zone”1. Therefore, additional non-invasive diagnostic biomarkers are urgently needed to substitute/complement PSA. In this se...

Endocrine-metabolic alterations such as obesity and metabolic syndrome are closely linked to the development of chronic liver diseases, from metabolic-associated fatty liver (MAFLD) to non-alcoholic steatohepatitis (NASH) and hepatocellular carcinoma (HCC). An emerging hallmark of endocrine-metabolic and hepatic diseases is the appearance or altered expression of pathological splicing variants (SVs). In fact, the components of the cellular machinery involved in the splicing pr...
