Uric Acid Functions as an Endogenous Modulator of Microglial Function and Amyloid Clearance in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Higher serum UA levels are associated with reduced AD risk in epidemiological studies. UA enhances microglial phagocytic capacity primarily by restoring CD36 and TREM2 receptor recycling that is impaired by Aβ exposure. Therapeutically, UA supplementation improves cognitive function and reduces neuropathology in AD mouse model by enhancing microglial ...

Predicting MammaPrint Recurrence Risk from Breast Cancer Pathological Images Using a Weakly Supervised Transformer

open access: yesAdvanced Science, EarlyView.
This study presents CPMP, a weakly supervised transformer model that predicts MammaPrint recurrence risk directly from routine histopathological images of early‐stage HR+/HER2− breast cancer patients. CPMP enables spatial heatmap visualization, analysis of cellular‐level interaction patterns, and an in‐depth characterization of morphological phenotypes

ITM2B Truncation Promotes Migrasome Formation to Accelerate Renal Cell Carcinoma Growth

open access: yesAdvanced Science, EarlyView.
This study identifies truncated ITM2B as a regulator of migrasome formation in renal cell carcinoma (RCC) cells. The ITM2B truncation not only facilitates migrasome formation by recruiting TSPAN4, but also sorts active caspase‐7 into migrasomes. The internalization of active caspase‐7‐enriched migrasomes by macrophages stimulates IL‐6 secretion to ...

Substrate identification of putative NCS1 and NCS2 nucleobase transporters in Pseudomonas aeruginosa

open access: yesmBio
Pseudomonas aeruginosa is an opportunistic pathogen that can salvage nucleobases from the environment to conserve nutrients that would otherwise be spent on de novo nucleotide biosynthesis.

2,6-Bis[4-(4-butylphenyl)-1H-1,2,3-triazol-1-yl]-9-dodecyl-9H-purine

open access: yesMolbank, 2019
Target 2,6-bis[4-(4-butylphenyl)-1H-1,2,3-triazol-1-yl]-9-dodecyl-9H-purine has been prepared via a Cu(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition reaction between 2,6-diazido-9-dodecyl-9H-purine and 4-n-butyl(phenylacetylene) in a 29% yield. The

Proteogenomic Characterization Reveals Metabolic Vulnerabilities and Aberrant Phosphorylation in Colorectal Metastasis to Liver

open access: yesAdvanced Science, EarlyView.
This study provides a multi‐omics landscape of treatment‐naïve colorectal liver metastasis and reveals dysregulated molecules and cellular pathways. SHMT1 and NDRG1 Ser330 phosphorylation are demonstrated to display crucial roles in tumorigenesis and liver metastasis. Two proteomics subtypes (metabolism and RNA function) with distinct clinical outcomes

DNA intercalation and cleavage of an antitumor antibiotic dynemicin that contains anthracycline and enediyne cores [PDF]

open access: yes, 1990
Dynemicin is a hybrid containing anthraquinone and enediyne cores, which contribute to binding and cleavage of DNA, respectively. DNA strand scission by the antitumor antibiotic is significantly enhanced by the addition of NADPH or thiol compounds.

Activation of USP30 Disrupts Endothelial Cell Function and Aggravates Acute Lung Injury Through Regulating the S‐Adenosylmethionine Cycle

open access: yesAdvanced Science, EarlyView.
USP30 deubiquitinates and stabilizes MAT2A, thereby regulating DNA methylation and miRNA expression, which ultimately leads to disruption of lung endothelial barrier and inflammation. Abstract Microvascular dysfunction is a key contributor to the development of acute inflammatory diseases, characterized by heightened vascular hyperpermeability and ...
