There is increasing evidence that alterations in alternative splicing can be linked to key tumor features in cancer. Dysregulations in the splicing machinery constitute the underlying cause in many of these alterations and, consequently, splicing and its control are emerging as a novel and transversal cancer hallmark, due to its association with different dysfunctions of tumor cells. In line with this, we discovered the existence of aberrantly spliced variants of somatostatin ...

Context: Sodium-glucose cotransporter 2 (SGLT2) inhibitors induce glycosuria and improve glycemic control, β cell function and insulin sensitivity in type 2 diabetes mellitus (DM2). On the other hand, these drugs predispose to diabetic ketoacidosis by increasing the tonus of glucagon. Glucagon acts on the liver and has no relevant effect on peripheral lipolysis and release of free fatty acids (FFA) as a substrate for ketogenesis, an action attributed to growth hormone (GH...

The role of adjuvant external beam radiotherapy (EBRT) in differenciated thyroid cancer (DTC) is controversial. It remains unknown whether EBRT in the neck following conventional treatment might improve progression-free survival (PFS) and overall survival (OS).Objective: To assess EBRT outcomes in patients with locally advanced DTC in terms of local disease progression, PFS and OS.Material and Methods: A multicentric retrospective ...

Dysregulation of the splicing machinery is emerging as a novel cancer hallmark due to its association with multiple dysfunctions in tumor cells. An inappropriate function of the components of this machinery (spliceosome) could be primarily linked with the generation of tumor-associated aberrant splicing variants. In line with this, we have previously reported that overexpression of aberrantly spliced variants of somatostatin receptor 5 (sst5TMD4) and ghrelin (In1-ghrelin) is d...

: Hepatic steatosis is a common obesity-associated pathology characterized by the accumulation of fat within the liver, which can progress to liver fibrosis, cirrhosis and ultimately lead to hepatocellular carcinoma. Remarkably, obesity and cancer course with a profound dysregulation of the genetic expression patterns and, particularly, with the aberrant expression of splicing variants that could contribute to the aggressiveness and comorbidities of these pathologies. Since th...

Introduction: Obesity is a growing worldwide public health issue and it is associated with multiple comorbidities, namely the so called Male Obesity-associated Secondary Hypogonadism (MOSH). However, the mechanisms that explain this association are not fully understood.Methods: Cross-sectional study of 163 obese men that were evaluated for several clinical and analytic parameters. Testosterone deficiency was defined as: total testosterone <2.8 ng/ml ...

: Prostate cancer (PCa) is the most common cancer among men in developed countries. Unfortunately, the heterogeneity of this malignancy hinders the finding of new biomarkers and therapeutic tools. A potential factor contributing to PCa is alternative splicing, which can generate the appearance of oncogenic variants involved in PCa aggressiveness. Thus, we hypothesized that the alteration of the splicing machinery (spliceosome components and splicing factors (SFs)) could be ass...

Prevalence of metabolic syndrome (MetS) and type-2 Diabetes (T2D) is growing dramatically worldwide. Loss of phenotypic flexibility, i.e. the difficulty to cope with different stressors to maintain metabolic homeostasis, contributes critically to the development of MetS/T2DM. Thus, it is essential to identify the key modifiers of phenotypic plasticity that define an individual’s susceptibility to develop T2DM. In this scenario, emerging evidence indicates that, under adve...

Obesity, a disease that is growing at epidemic proportions worldwide, is caused by a combination of genetic and lifestyle factors. One of the most common pathologies associated with obesity is hepatic steatosis, an accumulation of fat within the liver that can progress to liver fibrosis, cirrhosis, and ultimately lead to hepatocellular carcinoma. There is emerging evidence that alternative mRNA splicing, the key mechanism providing transcript and protein diversity, is dysregul...

Background: Bariatric surgery has been associated with a decrease in multiple obesity-related comorbidities including obstructive sleep apnoea syndrome (OSA). This study aims to access the OSA evolution in obese patients who underwent bariatric surgery.Methods: Retrospective longitudinal study of a population of obese patients who underwent bariatric surgery between January/2010 and July/2014 in our centre. Only patients who have undergone polysomnograph...
