Polystyrene Nanoplastics Drive β‐Cell Dedifferentiation Through Dendritic Cell‐Intrinsic MHC‐I‐Dependent Inflammatory Crosstalk

open access: yesAdvanced Science, EarlyView.
Polystyrene nanoplastics disrupt pancreatic immune–endocrine homeostasis by promoting MHC‐I‐associated dendritic cell activation and inflammatory crosstalk with β cells. This immune remodeling drives β‐cell dedifferentiation, impairs insulin secretion, and aggravates metabolic dysfunction, revealing a previously unrecognized immunometabolic mechanism ...

Situated Cultural Entrepreneurship

open access: yesArtivate, 2013
In this essay, I investigate the relationship between local political context and entrepreneurship in the arts, specifically entrepreneurship by cultural institutions, which I refer to as “cultural entrepreneurship.” I look at cultural entrepreneurship ...

OAF Blocks SIAH1‐Mediated Degradation of SCPX, a Therapeutic Strategy for MASLD

open access: yesAdvanced Science, EarlyView.
This study shows OAF directly binds to SCPX and inhibits its interaction with the E3 ligase SIAH1, thereby protecting SCPX from ubiquitin‐dependent degradation and stabilizing its levels. This OAF‐SCPX axis represents a novel pathway in lipid homeostasis, highlighting OAF as a promising therapeutic candidate for MASLD.

The Cicvarićs as Pioneers of Cultural Entrepreneurship in Serbia

open access: yesKonservatoryum, 2023
In this article, I focus on the activities of the Cicvarićs, a notable Roma music family from the western Serbian town of Šabac. I begin by overviewing cultural entrepreneurship and its characteristics and then provide the context for a discussion of the

AHR‐Responsive Carbon Dots Orchestrate Skin Wound Healing and Colonic Mucosal Repair via Treg‐Mediated Macrophage Efferocytosis

open access: yesAdvanced Science, EarlyView.
Guided by pharmacophore modeling and molecular docking, aryl hydrocarbon receptor (AHR)‐responsive carbon dots were synthesized. They bind directly to AHR and expand gut‐resident regulatory T (Treg) cells. Treg‐derived C‐C motif chemokine ligand 1 (CCL1) enhances macrophage efferocytosis, creating a pro‐regenetative niche that promotes colonic mucosal ...

USP4‐Dependent CHAF1B Stabilization Regulates Distinct SETDB1 Ubiquitin States Linked to AKT T308 Signaling and Lipogenic Remodeling in HCC

open access: yesAdvanced Science, EarlyView.
USP4 stabilizes CHAF1B by limiting K48‐linked ubiquitination. Stabilized CHAF1B supports UHRF1‐associated K63‐linked SETDB1 ubiquitination and cytoplasmic redistribution, whereas CHAF1B loss favors VHL‐dependent K11‐associated degradative ubiquitination and proteasomal loss of SETDB1.

How and why to study mountains: topics and types of research between limits and opportunities

open access: yesEtnoAntropologia
Field practice in a neighbouring ethnographic context – both culturally and geographically –, of which the researcher is a part, entails specific difficulties, epistemological and practical problems quite different from those faced by classical ...

Metabolic Signatures for Liver Cancer Diagnosis and Mechanistic Insights: A Large‐Scale, Multicenter Study

open access: yesAdvanced Science, EarlyView.
A large‐scale multicenter serum metabolomics study (13 centers, n = 2,149) identified a 9‐metabolite + AFP diagnostic signature for liver cancer (AUC = 0.93). Among the signature, nicotinamide (NAM) was validated as an oncometabolite: NAM enhances NAD+ synthesis, activating SIRT1 to deacetylate and stabilize HIF1α, thereby driving glycolysis, MAPK ...

Hepatic Lipid Stress Drives Metabolic Dysfunction‐Associated Steatohepatitis Progression through FTO O‐GlcNAcylation‐Induced m6A Demethylation of HRAS

open access: yesAdvanced Science, EarlyView.
Lipid stress drives O‐GlcNAcylation of the m6A demethylase FTO at Ser195, enhancing its stability and demethylase activity. This modification removes m6A from HRAS mRNA, preventing its degradation and activating PI3K/AKT signaling to promote hepatic steatosis and inflammation.
