Gliomas are derived from glial-cells and are the most common primary brain tumor, characterized by rapid growth and invasion. Astrocytomas are a subset of malignant gliomas which are classified, based on their agresiveness features, in low grades (I and II) to high grades (HGAs; III and IV), being grade-IV (glioblastoma multiforme; GBM) the most malignant and aggressive type. Current standard treatment for GBMs consists on surgery followed by radiotherapy/chemotherapy; however...

Background: Gliomas are the most common primary brain tumor, being astrocytomas a subset of malignant gliomas graded on a scale of I to IV. Grade-IV astrocytomas (glioblastoma multiforme; GBM) are the most malignant and aggressive type. Current standard treatments are ineffective, being their average postoperative survival of 12-16 months. Therefore, there is a clear need for the identification of novel therapeutic targets to treat this pathology. In this context, the truncate...

Hepatocellular carcinoma (HCC) is an aggressive tumour frequently associated to an underlying chronic liver disease. In this sense, metabolic dysfunction-associated steatotic liver disease (MASLD) is considered as a growing cause of HCC development. Considering the need of novel therapeutic approaches, and the promising data about targeting the tumour microenvironment in cancer, we performed quantitative proteomics on HCC samples to characterize the components and regulators o...

Prostate cancer (PCa) is one the leading causes of cancer-related deaths among men in developed countries. Therefore, identification of novel molecular and therapeutic approaches to tackle this pathology are urgently needed. In this scenario, our group has recently reported that elements of the cellular machinery controlling alternative splicing processes might be used as potential novel therapeutic tools against PCa and castration-resistant PCa (CRPC). In this context, RBM22 ...

Glioblastoma (GBM; grade IV astrocytoma) is one of the most devastating endocrine-related cancer worldwide based on its locally aggressive behavior and because it cannot be cured by current therapies. Therefore, the identification of novel diagnostic and prognostic biomarkers, and especially efficient therapeutic targets is urgently needed. In this sense, defects in alternative splicing process are associated with poor survival and high aggressiveness in cancer, including GBM....

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...

Prostate cancer (PCa) is one of the most common causes of cancer-related deaths in men worldwide. Therefore, more specific non-invasive diagnostic biomarkers as well as novel therapeutic targets are urgently needed. As miRNAs have been proposed as promising elements for the identification of novel diagnostic and therapeutic tools for different pathologies, including cancer, we investigated the miRNA landscape in PCa patients and explored their putative diagnostic/therapeutic u...

Glioblastoma (GBM; grade IV astrocytoma) is the one of the most malignant and lethal endocrine-related cancers worldwide. Current standard treatment consists of surgery followed by radiotherapy and/or chemotherapy; however, this is only a palliative approach with a mean post-operative survival of scarcely ~12-15 months. Therefore, the identification of novel therapeutic targets to treat this devastating pathology is urgently needed. In this context, the truncated splicing-vari...

Methods: Descriptive retrospective study of the clinical outcomes and RNA expression in aggressive pituitary tumors treated with temozolomide. RNA expression was studied in tumor samples normalized to housekeeping genes including GH, POMC, PRL, αsub, FSH, LH, TSH, sst1, sst2, sst3, sst5, sst5b, sst5c, DR1, DR2T, DR2L, DR4, DR5, Ghrelin, In1-Ghrelin, GOAT, GHRR1b, AVPR1b, GHRH-R, GnRH-R, Ki-67, PTTG1, CRHR1.Results: Ten patients were treated. 30% (3)...

Objective and methods: Recent studies suggest that altered alternative splicing and, consequently, appearance of an abnormal splicing pattern and even of aberrant/oncogenic splicing-variants, represent a common molecular feature of most tumor pathologies, including Pituitary Neuroendocrine Tumors (PitNETs). However, the putative alteration, pathophysiological role and potential therapeutic utility of splicing machinery components [i.e. spliceosome-components (SCs) and splicing...
