A Conjugation Delivery System of Macrophages and Platelet Pharmacytes Promotes Regeneration After Spinal Cord Injury

Advanced Science, EarlyView.
A macrophage–platelet conjugation system (M‐P‐NPs@PPARγ) targets injure tissue to co‐deliver platelet mitochondria and PPARγ‐encoding NPs. This strategy boosts the macrophage energy supply and restores lipid homeostasis, leading to synergistically enhanced efferocytosis and tissue repair Abstract Mitochondrial dysfunction occurs in macrophages with ...

Peroxisomal Localization of a Truncated HMG-CoA Reductase under Low Cholesterol Conditions

Biomolecules
3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase, HMGCR) is one of the rate-limiting enzymes in the mevalonate pathway required for cholesterol biosynthesis.

A Novel CYP2E1 Inhibitor, 4‐Methyl‐5‐Acetylthiazole (Q11), Alleviates Obesity Via Modulating Adipose Inflammation and Mitochondrial Dysfunction

Advanced Science, EarlyView.
Obesity involves chronic inflammation and mitochondrial dysfunction. This study identifies cytochrome P450 2E1 (CYP2E1) as a novel inflammatory target in adipose tissue. Its activity increases in obese mice and correlates with inflammation and mitochondrial impairment.

Sensitive analysis of serum 3α, 7α, 12α,24-tetrahydroxy-5β-cholestan-26-oic acid diastereomers using gas chromatography–mass spectrometry and its application in peroxisomal d-bifunctional protein deficiency

Journal of Lipid Research, 1998
The final steps in bile acid biosynthesis take place in peroxisomes and involve oxidative cleavage of the side chain of C27-5β-cholestanoic acids leading to the formation of the primary bile acids cholic acid and chenodeoxycholic acid.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

Advanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

Advanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.

Peroxisome Biogenesis Disorders

Translational Science of Rare Diseases, 2016
The peroxisome biogenesis disorders (PBD) are a heterogeneous group of autosomal recessive disorders in which peroxisome assembly is impaired, leading to deficiencies of peroxisomal enzymes, complex developmental sequelae and progressive disabilities.

Ultrasound Controlled‐Release Hydrogel Promotes Diabetic Wound Healing via Neuroimmune Modulation and Synergistic ROS Scavenging

Advanced Science, EarlyView.
This study presents an ultrasound‐responsive hydrogel (MCF@CA) that co‐delivers a neuropeptide (CGRP) and a ROS‐scavenging manganese porphyrin to diabetic wounds. The system restores neuro‐immune communication, reprograms macrophages toward an anti‐inflammatory phenotype, and clears excess ROS, thereby accelerating wound closure and promoting mature ...

Peroxisomes: surprisingly versatile organelles

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2002
Peroxisome development is a dynamic process that is not yet completely understood. We use the methylotrophic yeast Hansenula polymorpha as model in our studies on peroxisome homeostasis. Cells of this species may contain different types of peroxisomes that differ in protein composition and capacity to incorporate matrix proteins.

Conversion of Transplanted Mature Hepatocytes into Afp+ Reprogrammed Cells for Liver Regeneration After Injury

Advanced Science, EarlyView.
Donor‐derived tdTomato+ mature hepatocytes were FACS‐isolated and transplanted into Fah−/− host mice. During regeneration, these cells convert into proliferative, unipotent Afp+ rHeps. Their plasticity is governed by a PPARγ/AFP‐dependent metabolic switch, segregating into pro‐proliferative Afplow and pro‐survival Afphigh subpopulations.
