NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

open access: yesAdvanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

Matrix metalloproteinases in liver injury, repair and fibrosis. [PDF]

open access: yes, 2015
The liver is a large highly vascularized organ with a central function in metabolic homeostasis, detoxification, and immunity. Due to its roles, the liver is frequently exposed to various insults which can cause cell death and hepatic dysfunction ...

P300 Acetyltransferase Mediates Stiffness-Induced Activation of Hepatic Stellate Cells Into Tumor-Promoting Myofibroblasts.

open access: yesGastroenterology, 2018
BACKGROUND & AIMS Hepatic stellate cells (HSCs) contribute to desmoplasia and stiffness of liver metastases by differentiating into matrix-producing myofibroblasts.

Biocatalytic Nanoregulators Restore Joint Redox‐Immune Homeostasis in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Mesenchymal stem cell‐derived extracellular vesicles (EVs) coat ruthenium‐loaded metal‐organic frameworks (Ru@ZrMOF), creating a targeted therapeutic (Ru@ZrMOF/EVs). This platform scavenges ROS, generates oxygen, and polarizes macrophages from M1 to M2, alleviating inflammation, inhibiting pannus, promoting cartilage repair, and downregulating HIF‐1α ...

miR-12135 ameliorates liver fibrosis accompanied with the downregulation of integrin subunit alpha 11

open access: yesiScience
Summary: Cirrhosis is becoming one of the most common diseases worldwide. Abnormal upregulation of transforming growth factor β (TGF-β) signaling plays a pivotal role in the excess activation of hepatic stellate cells.

N-Cadherin cleavage during activated hepatic stellate cell apoptosis is inhibited by tissue inhibitor of metalloproteinase-1. [In supplement: 11th International Symposium on the Cells of the Hepatic Sinusoid and their Relation to Other Cells] [PDF]

open access: yes, 2004
Apoptosis of hepatic stellate cells (HSC) has previously been shown to occur during spontaneous resolution of experimental liver fibrosis. TIMP-1 has also been shown to have a key role because of its ability to inhibit apoptosis of HSC via matrix ...

Targeted Drug Delivery to Hepatic Stellate Cells for the Treatment of Liver Fibrosis

open access: yesJournal of Pharmacology and Experimental Therapeutics, 2019
Liver fibrosis is caused by excessive accumulation of extracellular matrix during chronic liver injuries. Although clinical evidence suggests that liver fibrosis can be reversed, there is no standard therapy for liver fibrosis.

METTL1‐Mediated M7G tRNA Modification Promotes Residual Liver Regeneration After Hepatectomy via Translational Control

open access: yesAdvanced Science, EarlyView.
METTL1 and its mediated m7G tRNA modification are significantly up‐regulated after partial hepatectomy (PHx). Overexpression of METTL1 improves the efficiency of liver regeneration after PHx, increases the proliferation of hepatocytes, and accelerates the recovery of liver function.

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

open access: yesAdvanced Science, EarlyView.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...
