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 ...

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

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...

: 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...

The liver of obese patients with hepatic steatosis exhibits a severe dysregulation of key splicing machinery components as compared to obese patients without hepatic steatosis

Rio-Moreno Mercedes del , Pedraza-Arevalo Sergio , Gonzalez-Rubio Sandra , Ferrin Gustavo , Gahete Manuel D , Rodriguez-Peralvarez Manuel , Kineman Rhonda D , Ibanez-Costa Alejandro , de la Mata Manuel , Castano Justo P , Luque Raul M

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...

Splicing machinery landscape is dysregulated in chronic liver disease: central role of EIF4A3 in hepatocarcinogenesis.

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...

Somatostatin and ghrelin systems characterization reveals a central role in chronic liver disease

Background: Hormonal signalling plays a key role in the progression of non-alcoholic fatty liver disease (NAFLD) to hepatocellular carcinoma (HCC). However, the role of somatostatin (SST), cortistatin (CORT), neuronostatin (NST) and ghrelin systems in NAFLD-HCC progression has not been elucidated.Objectives: To characterize the role of SST/CORT/NST and ghrelin systems in chronic liver disease and evaluate its clinical potential.Met...

Dysregulation of splicing factor 3B SUBUNIT 1 (SF3B1) is associated with the pathological transformation of the liver: Pharmacological inhibition with pladienolide-B as novel therapeutic tool in liver disease

Jiménez Vacas1 Juan Manuel , López-Cánovas Juan L , Del Rio-Moreno Mercedes , García-Fernandez Helena , Sánchez-Frias Marina E , Amado Victor , L-López Fernando , Fondevila Marcos F , Ciria Ruben , Briceño Javier , Nogueiras Rubén , De la Mata Manuel , Castaño Justo P , Rodriguez-Perálvarez Manuel , Luque Raúl M , Gahete Manuel D

Development and progression of liver diseases, from non-alcoholic fatty liver disease (NAFLD) to steatohepatitis (NASH), and hepatocellular carcinoma (HCC), seem to be accompanied by a dysregulation of the expression of alternative splicing variants (SVs) and appearance of aberrant SVs. The splicing factor 3B subunit 1 (SF3B1) represents a crucial player for the functional assembly of the spliceosome, the core machinery that controls the splicing process, and its activity can ...
