Molecular Expression and Characterization of Erythroid-Specific 5-Aminolevulinate Synthase Gain-of-Function Mutations Causing X-Linked Protoporphyria

Molecular Medicine, 2013
X-linked protoporphyria (XLP) (MIM 300752) is a recently recognized erythropoietic porphyria due to gain-of-function mutations in the erythroid-specific aminolevulinate synthase gene (ALAS2).

Antioxidative Effect of Protoporphyrin and Increase of Glutathione in Protoporphyrin-Administered Rat Liver.

Biological and Pharmaceutical Bulletin, 1993
The effect of protoporphyrin (PP) administration on the activities of enzymes related to and/or involved in lipid peroxidation and on the content of reduced glutathione (GSH) was investigated in rat liver. PP, at an intravenous dose of 20 mg/kg, increased GSH content, caused a weak suppression of NADPH-cytochrome c reductase activity and a slight ...

Characterization of Metal-Protoporphyrins as Potential Photosensitizers for Engineered Photoresponsive Proteins

Journal of Photochemistry and Photobiology
Metallo-protoporphyrin IX (PpIX) offer a versatile platform for engineering photoresponsive proteins (EPrPs), yet their photophysical and photochemical properties upon interaction with proteins remains insufficiently characterized.

THBS1+ Macrophages Exacerbate Modic Changes via SDC4‐Dependent Activation of NLRP3 Inflammasome

Advanced Science, EarlyView.
The illustration of THBS1+ macrophages exacerbate MCs via SDC4‐dependent activation of the NLRP3 inflammasome. THBS1+ macrophage subpopulation was identified in MCs through single‐cell RNA sequencing. C. acnes and its metabolites activate THBS1 expression in macrophages via the TLR signaling pathway.

Mapping Steroidogenic Perturbations Under Endocrine Disruptor Mixtures Across Demographic Subgroups: Structural and Metabolomic Insights

Advanced Science, EarlyView.
Population‐scale EDC–hormone association mapping among 4255 participants across demographic subgroups identifies phthalate metabolites as the most consistent signals associated with lower testosterone‐related markers in males. Integrative mechanistic validation prioritizes MCPP as a key phthalate metabolite linked to CYP17A1‐centered disruption of ...

G‐Quadruplexes: Structural Diversity and Emerging Roles in Biomolecular Condensation

Advanced Science, EarlyView.
G‐quadruplexes (G4s) fold into diverse intra‐ and intermolecular structures, positioning them as emerging regulators of biomolecular condensation. Mechanistically, G4s autonomously form condensates, act as structural platforms to initiate and stimulate condensation, or induce phase transitions.

Elimination of Fusobacterium nucleatum With Biomimetic Nanoparticles to Reverse Tumor Immunosuppression and Enhance Colorectal Cancer Therapy

Exploration, EarlyView.
Tumor‐related pathogenic bacteria can affect the treatment efficiency of tumors. Therefore, we have designed a nanoparticle that can accurately target tumor cells and related pathogenic bacteria, reverse the immunosuppressive effect of pathogenic bacteria on tumors, and synergistically enhance tumor treatment efficiency through sonodynamic therapy ...

Current Cell/Organoid and Animal Models for Primary Sclerosing Cholangitis

Portal Hypertension &Cirrhosis, EarlyView.
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease with limited therapeutic options and a marked risk of progression to biliary fibrosis, cirrhosis, and malignancy. Progress in PSC research has been hindered by the lack of models that faithfully recapitulate the complex biliary microenvironment and disease heterogeneity ...

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
