A Metal‐Free Carbon Monoxide Prodrug Suppresses Metastasis of Pancreatic and Breast Cancer

Advanced Science, EarlyView.
A metal‐free carbon monoxide (CO) prodrug, CO‐116, delivers controlled systemic CO without inhalation. CO suppresses the HRG1–heme axis, reducing intracellular heme availability. Attenuation of this pathway inhibits metastatic progression in pancreatic and triple‐negative breast cancer models.

3-Methyladenine ameliorates liver fibrosis through autophagy regulated by the NF-κB signaling pathways on hepatic stellate cell

OncoTarget, 2017
3-Methyladenine (3-MA) is a selective type III phosphatidylinositol 3-kinase (PI3K) inhibitor and also blocks autophagosome formation. However, the effect of 3-MA in liver fibrosis has yet to be determined. Recent studies have demonstrated that autophagy

Layered Long Term Co-Culture of Hepatocytes and Endothelial Cells on a Transwell Membrane: Toward Engineering the Liver Sinusoid

, 2013
This paper presents a novel liver model that mimics the liver sinusoid where most liver activities occur. A key aspect of our current liver model is a layered co-culture of primary rat hepatocytes (PRHs) and primary rat liver sinusoidal endothelial cells

NUP85 Mediates Endoplasmic Reticulum Stress through the USP47/ASK1 Signaling Pathway to Regulate the Progression of Liver Fibrosis

Advanced Science, EarlyView.
In the present study, we have demonstrated that the NUP85‐USP47‐ASK1 signaling pathway may have regulated the progression of liver fibrosis through modulating ERS. Additionally, we have developed a CREKA‐coupled liposome to target delivery of MV, a pharmacological inhibitor of NUP85, to activated HSCs, thereby attenuating liver fibrosis. ABSTRACT Liver

Neuronal injury and hepatotoxicity: astrocytes and stellate cells convergence and their role in tissue repair

Frontiers in Neuroscience
In the central nervous system, astrocytes are highly specialized non-neuronal cells that are key elements in maintaining neuronal microenvironment homeostasis.

Endogenous Ceramide 24:1 Constrains Th17‐Driven Neutrophilic Inflammation by Antagonizing EP2 Signaling

Advanced Science, EarlyView.
Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.

Effects of dietary retinoid and triglyceride on the lipid composition of rat liver stellate cells and stellate cell lipid droplets

Journal of Lipid Research, 1988
Hepatic stellate cells store the majority of the liver's retinoid (vitamin A) reserves as retinyl esters in stellate cell lipid droplets. A study was conducted to explore the effects of differences in dietary retinoid and triglyceride intake on the ...

Stiffening hydrogels for investigating the dynamics of hepatic stellate cell mechanotransduction during myofibroblast activation

Scientific Reports, 2016
Tissue fibrosis contributes to nearly half of all deaths in the developed world and is characterized by progressive matrix stiffening. Despite this, nearly all in vitro disease models are mechanically static.

Ammonia Detoxification Inhibits Liver Metastasis by Reshaping Hepatic Microenvironment

Advanced Science, EarlyView.
Liver metastasis diverts aspartate into hyperactive pyrimidine synthesis, disrupting urea cycling and causing pathogenic ammonia accumulation. Ammonia dually reprograms the microenvironment by: (1) activating hepatic stellate cells (HSCs) into pro‐fibrotic metastasis‐associated fibroblasts (MAFs), and (2) suppressing anti‐tumor monocytes/macrophages ...

Hepatocyte BDNF Acts as a Novel Immune Checkpoint to Restrain TLR4‐Mediated Acute Hepatitis

Advanced Science, EarlyView.
This study identifies hepatocyte‐derived BDNF as an endogenous TLR4 antagonist that alleviates acute hepatitis. BDNF is downregulated in hepatocytes via REST‐mediated transcriptional repression during ALI/ALF. Mechanistically, BDNF binds to TLR4 on macrophages to suppress inflammation.
