Nanozyme‐Reinforced miR‐197‐3p Delivery Resets Metabolic and Senescence Pathways to Rejuvenate Osteoarthritic Cartilage

Advanced Science, EarlyView.
ABSTRACT Osteoarthritis (OA) is a progressive and disabling joint disease driven by oxidative stress, chondrocyte senescence and extracellular matrix (ECM) degradation, yet lacks effective disease‐modifying treatments. In this study, we identified miR‐197‐3p as a previously unrecognized, cartilage‐protective miRNA significantly downregulated in both ...

Targeting NSUN2‐Mediated m5C Modification Attenuates Chondrocyte Senescence and NLRP3 Activation in Osteoarthritis

Advanced Science, EarlyView.
NSUN2‐mediated m5C modification cooperates with ALYREF to stabilize and export IP3R3 mRNA, increasing IP3R3 expression and Ca2 + overload in chondrocytes. This signaling promotes mitochondrial dysfunction, NLRP3 inflammasome activation, and senescence, thereby accelerating osteoarthritis progression.

Informe final del proyecto: Rol de mitocondria en la secreción de vesículas extracelulares por células senescentes

Las células pueden entrar en un estado llamado senescencia celular, en el cual dejan de dividirse, pero continúan activas metabólicamente y liberan diversas señales hacia su entorno.

Targeting p21‐High Senescent Kupffer Cells Nanotherapeutically Potentiates Antitumor Immunity in Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

Advanced Science, EarlyView.
Schematic illustration of a biomimetic SKEV@AAV platform targeting p21‐high senescent Kupffer cells (sKCs) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). p21‐high sKCs accumulate in the PVTT microenvironment and establish an immunosuppressive, SASP‐rich environment that facilitates tumor cell proliferation and immune evasion.

Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, EarlyView.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...

Modulation of Lung Adenocarcinoma by Phosphorylated FOXN3‐Mediated Transcriptional Inactivation of p53

Advanced Science, EarlyView.
In non‐tumorous lung tissues, FOXN3 promotes the transcriptional activation of p53 by facilitating its recruitment to target promoters, thereby suppressing lung tumorigenesis through activation of the p53 signaling pathway. Conversely, in lung adenocarcinoma tissues, hyperphosphorylated FOXN3 dissociates from the promoters of p53‐responsive genes and ...
