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...

Presence and clinical-histological correlates of ghrelin and somatostatin systems components in gastroenteropancreatic neuroendocrine tumors and lung carcinoids

Herrera-Martinez Aura D , Gahete Manuel D , Sanchez-Sanchez Rafael , Salas Rosa Ortega , Blanch Raquel Serrano , Salvatierra Juan , Luque Raul , Moreno Maria A Galvez , Castano Justo P

Neuroendocrine tumors (NETs) are uncommon neoplasms with increasing incidence and limited therapeutic options, wherein identification of new diagnostic/prognostic/therapeutic biomarkers is urgently required. Alterations in somatostatin (SST)/cortistatin (CORT) and ghrelin systems have been associated to development/progression of several cancers. Thus, we evaluated expression levels of SST/CORT/ghrelin system components in gastroenteropancreatic-neuroendocrine tumors (GEP-NETs...

Expression of ghrelin and somatostatin systems components in pancreatic neuroendocrine tumours and their relationship with clinical-histological characteristics

Herrera-Martinez Aura D , Gahete Manuel , Sanchez-Sanchez Rafael , Cuenca Teresa Caro , Blanch Raquel Serrano , Luque Raul , Moreno Maria A Galvez , Castano Justo

Pancreatic neuroendocrine tumors (PNETs) are uncommon neoplasms from the endocrine pancreas, whose incidence is recently rising. Unfortunately, an advanced stage is often found at diagnosis; thus, identification of new molecular diagnostic, prognostic, and therapeutic markers is required. Ghrelin and somatostatin/cortistatin systems are two multifunctional regulatory complexes widely distributed throughout multiple tissues, including the pancreas, where they exert diverse (pat...

The truncated somatostatin receptor sst5TMD4 is overexpressed in prostate cancer, where it increases aggressiveness features by regulating key tumor suppressors and oncogenes.

Somatostatin is a pleiotropic neuropeptide that governs multiple biological targets, including tumor cell function, through a family of G protein-coupled receptors with 7-transmembrane domains (TMD), named sst1-5. However, we recently discovered sst5TMD4, an aberrantly spliced, truncated (only 4-TMDs) sst5-variant displaying unique molecular/functional features. sst5TM4 is overexpressed in various endocrine-related tumors exacerbating their malignant characteristics. Here, we ...

A new generation somatostatin-dopamine chimeric analogue exerts potent antitumoral actions on primary pituitary neuroendocrine tumor cells

Alors-Perez Emilia , Vazquez-Borrego Mari C , L-Lopez Fernando , Galvez-Moreno Maria A , Fuentes-Fayos Antonio C , Venegas-Moreno Eva , Herrera-Martinez Aura D , Blanco-Acevedo Cristobal , Solivera Juan , Landsman Tanya , D Gahete Manuel , Soto-Moreno Alfonso , Culler Michael D , Castano Justo P , Luque Raul M

Pituitary neuroendocrine tumors (PitNETs) constitute approximately 15% of all intracranial tumors and comprise a varied type of neoplasms that, despite being rarely metastatic, can cause severe comorbidities and increased mortality related to the mass effects and hormonal hypersecretion. The high expression levels of somatostatin and dopamine receptors in these tumors has led to the use of somatostatin analogues (SSAs) and dopamine agonists (DAs) as pharmacological treatments....

Dysregulation of alternative splicing unveils new avenues for targeting pulmonary carcinoids

IntroductionDysregulation of alternative splicing is emerging as a new hallmark of cancer. This dysregulation may originate from mutations and/or altered expression of specific components of the splicing machinery. Indeed, our group has shown that the expression profile of the splicing machinery is altered in several types of cancer, including endocrine-related cancers. However, to date, the status of alternative splicing and its putative dysregulation h...
