Shared gene signatures and key mechanisms in the progression from liver cirrhosis to acute-on-chronic liver failure
2025-08-26
(Press-News.org) Background and objectives
Chronic liver cirrhosis (LC) and acute-on-chronic liver failure (ACLF) are interconnected hepatic disorders associated with substantial morbidity and mortality. Despite their distinct clinical characteristics, both conditions share common pathogenic pathways that remain inadequately understood. This study aimed to identify shared gene signatures and elucidate underlying molecular mechanisms.
Methods
In this study, we employed Weighted Gene Co-Expression Network Analysis to explore transcriptomic data from the Gene Expression Omnibus for LC and ACLF.
Results
Key co-expression modules enriched with genes involved in glycolysis and gluconeogenesis pathways were identified, implicating metabolic dysfunction as a central feature in both conditions. Furthermore, microRNA analysis revealed that hsa-miR-122 and hsa-miR-194 play pivotal roles in regulating these metabolic pathways, potentially contributing to immune dysregulation.
Conclusions
Our transcriptomic analysis has uncovered a potential pathogenic association between glucose metabolism and both ACLF and LC. This association is mediated by miR-122 and miR-194, along with their corresponding signaling pathways. These findings highlight novel therapeutic targets that warrant further in-depth exploration.

The study was recently published in the Journal of Translational Gastroenterology.
Journal of Translational Gastroenterology (JTG) dedicates to improving clinical diagnosis and treatment, advancing understanding of the molecular mechanisms, and promoting translation from bench to bedside of gastrointestinal, hepatobiliary, and pancreatic diseases. The aim of JTG is to provide a forum for the exchange of ideas and concepts on basic, translational, and clinical aspects of gastroenterology, and promote cross-disciplinary research and collaboration.

DALLAS, August 26, 2025 — Research shows that rural Americans are at 30% higher risk of stroke, are 40% more likely to develop heart disease and live an average of three years fewer than their urban counterparts.[1]
The American Heart Association, devoted to changing the future to a world of healthier lives for all, is committed to closing the gap between rural and urban health outcomes. To continue improving cardiovascular care in rural communities, the Association announced today the three-year funding extension of its Rural Health Care Outcomes Accelerator through June 2028.
Since its launch in ...

Emotions are complicated things. Researchers have found some differences between men and women, but basically the same factors play the biggest part in whether we feel good about ourselves.
“We investigated differences between the sexes and the relationships between factors that influence participants’ motivation and well-being,” said Professor Hermundur Sigmundsson at the Norwegian University of Science and Technology (NTNU’s) Department of Psychology.
He has spent many years studying what it takes for people to achieve their goals, and in this ...

Miami (August 26, 2025) – People with schizophrenia are more likely to develop chronic obstructive pulmonary disease (COPD), suggesting a possible syndemic relationship between the two diseases, in addition to people not seeking appropriate medical care. A new article examining the link between COPD and schizophrenia appears in the July 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open access journal.
COPD encompasses conditions including emphysema and ...

Human men are typically more aggressive than human women, a finding supported by reams of research. But surveys of 4,136 individuals in 24 countries reveal an exception to the trend: aggression in sibling relationships. Douglas T. Kenrick and Michael E.W. Warnum, along with a team of 49 colleagues, asked participants how often they had acted aggressively towards a sister, a brother, a female friend, a male friend, a female acquaintance, or a male acquaintance—both when they were children and when they were adults. Aggressive actions included both direct aggression, such as hitting/slapping ...

Chemicals used to replace bisphenol A (BPA) in food packaging can trigger potentially harmful effects in human ovarian cells, according to McGill University researchers.
A new study examined several chemicals commonly used in price stickers on packaged meat, fish, cheese and produce found early signs of potential toxicity.
The findings, published in the journal Toxicological Sciences, raise concerns about the safety of BPA-free packaging and whether current regulations go far enough to protect consumers.
BPA substitutes disrupt gene expression
The research began with the 2023 discovery by Stéphane Bayen, Associate Professor in McGill’s ...

Researchers explore the human tendency to look to the past to predict the future—even when people rationally know outcomes are completely random. A fair coin flip is the prototypically random-outcome event. Russell Roberts and colleagues asked 12,000 people to predict coin flip outcomes in a sequence of five fair coin tosses—some in person, some online. With such a large number of participants, they were able to analyze subsets of people who—by chance—made a series of successful or unsuccessful guesses without any deception or manipulation of the ...

Different countries have different cultures, and social scientists have developed theories about which values are most important in differentiating the world’s cultures. Abhishek Sheetal and colleagues used the power of machine learning to identify the crucial distinguishing characteristics of the world’s national cultures in a theory-blind manner. The authors trained a neural network to predict an individual’s country of origin from their attitudes, values, and beliefs, as measured by the World Values Survey, a global study that probes everything from religious beliefs ...

Catastrophes, by definition, are devastating, but they can often be catalysts for lasting, positive change – and if people can adopt that perspective, they may see some real benefits, a Stanford-led study suggests.
In a randomized, controlled trial, a one-hour intervention was given to a group of adults designed to shift their mindset, or core beliefs and assumptions, about having lived through a catastrophe like the COVID-19 pandemic, with the goal of seeing growth opportunities in the experience.
Those who received the intervention showed lower levels of depression three months later compared to a control group. Blood tests also revealed lower ...

An international team of astronomers, co-led by researchers at University of Galway, has made the unexpected discovery of a new planet.
Detected at an early stage of formation around a young analog of our own Sun, the planet is estimated to be about 5 million years-old and most likely a gas giant of similar size to Jupiter.
The study, which was led by Leiden University, University of Galway and University of Arizona, has been published in the international journal Astrophysical Journal Letters.
The ground-breaking discovery was made using ...
