Biogenesis of cytochrome c1 [PDF]

open access: yes, 1989
The biogenesis of cytochrome c1 involves a number of steps including: synthesis as a precursor with a bipartite signal sequence, transfer across the outer and inner mitochondrial membranes, removal of the first part of the presequence in the matrix ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

open access: yesAdvanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Single‐Position Peptide Clustering for Peptidomics Reveals Novel Disease Biomarkers and Dysregulated Proteolytic Characteristics

open access: yesAdvanced Science, EarlyView.
A novel amino acid (aa)‐score‐based single‐position peptide clustering strategy is developed for peptidomics, enabling precise profiling of protein proteolysis in plasma from β‐thalassemia cohort. The method identifies new aa position‐based peptide cluster biomarkers validated by heavy‐labeled peptides, visualizes aggregated changes, uncovers disease ...

Novel Vascularized Human Liver Organoids for Modeling Alcohol‐Induced Liver Injury and Developing Hepatoprotective Therapy

open access: yesAdvanced Science, EarlyView.
This study successfully engineered vascularized liver organoids (3HLOs) by co‐culturing human reprogrammed hepatocyte‐like cells (hrHLs) with human umbilical vein endothelial cells (HUVECs) and human umbilical mesenchymal stem cells (HUMSCs). Upon implantation, the 3HLOs established functional vascular anastomosis with the host circulation and ...

Inhibition of SLC11A1‐Mediated Lysosomal Iron Accumulation in Microglia Promotes Repair Following White Matter Stroke

open access: yesAdvanced Science, EarlyView.
Genetic and pharmacological inhibition of SLC11A1 functioning as an H+/Fe2+ antiporter–mediated lysosomal iron accumulation in microglia promotes lysosomal lumen acidification, increases CTSD expression, enhances lysosomal myelin debris uptake and degradation, and promotes repair following white matter stroke. ABSTRACT White matter stroke (WMS) results

Beyond Catalytic Therapy: Copper‐Paeonol Nanozymes Disrupt Fascin‐Mediated Actin Bundling to Suppress Tumor Growth and Metastasis

open access: yesAdvanced Science, EarlyView.
Copper‐paeonol nanozymes target tumor‐specific reactive oxygen species generation and disrupt fascin‐mediated actin bundling, effectively suppressing tumor growth and metastatic colonization. Abstract Fascin, an actin‐bundling protein universally upregulated in metastatic tumors, drives tumor migration and invasion by promoting filopodia and ...

PTG‐Dependent Glycogen Metabolic Dysfunction Drives Impaired Adipose Browning: A Novel Mechanism Linking PM2.5 to Metabolic Disorders

open access: yesAdvanced Science, EarlyView.
This study provides the first evidence that PM2.5 impairs iWAT browning via PTG‐mediated glycogen metabolism disruption, which is initiated by ADRB3 inhibition and subsequently triggers VEGFB upregulation. It thereby delineates the ADRB3‐PTG‐VEGFB axis as central to PM2.5‐induced metabolic dysfunction and identifies adipose glycogen metabolism as a ...
