Harnessing MDM2‐Mediated Targeted Degradation of Transcriptional and Epigenetic Machinery to Disrupt Oncogenic Addictions in Pediatric Sarcoma

Advanced Science, EarlyView.
MDM2 dependency in pediatric sarcomas is driven by a novel p53‐independent oncogenic cistrome alongside canonical p53 pathway suppression. This study introduces MDM2‐recruiting transcriptional and epigenetic machinery degraders (MDM2‐TEMADs) as a novel precision oncology modality.

Stress responsive miR-23a attenuates skeletal muscle atrophy by targeting MAFbx /atrogin-1 [PDF]

, 2008
Muscle atrophy occurs in many pathological states and results primarily from accelerated protein degradation by the ubiquitin-proteasome pathway. We used dexamethasone to induce muscle wasting and investigated the role of a microRNA (miRNA) in the ...

The Role of Ubiquitin and the 26S Proteasome in Plant Abiotic Stress Signaling

Frontiers in Plant Science, 2014
Ubiquitin is a small, highly conserved, ubiquitously expressed eukaryotic protein with immensely important and diverse regulatory functions. A well-studied function of ubiquitin is its role in selective proteolysis by the ubiquitin-proteasome system (UPS)

Dual Cytoplasmic and Chloroplastic Mechanisms Fine‐Tune Chloroplast Division through ARC3 Protein Stability

Advanced Science, EarlyView.
ARC3 levels are controlled by cytosolic and chloroplast proteolytic systems. PUB52 mediates ARC3 precursor ubiquitination and degradation in the cytosol, while CLPC1 promotes ARC3 degradation in chloroplasts, where ARC2 protects ARC3 from excessive breakdown. Disrupting these components causes chloroplast division defects, placing them upstream of ARC3.

FUCA2 Sustains AKT Signaling and Suppresses Senescence by Antagonizing FUT3‐Mediated ErbB3 Fucosylation in Lung Adenocarcinoma

Advanced Science, EarlyView.
ABSTRACT While targeted therapies have improved outcomes in lung adenocarcinoma (LUAD), many patients still lack targetable mutations. Here, we identified alpha‐L‐fucosidase 2 (FUCA2) as a crucial driver of LUAD by preventing cellular senescence. Mechanistically, through the restriction of fucosyltransferase 3 (FUT3)‐mediated α‐1,3‐fucosylation of ...

Loss of E3 Ubiquitin Ligase RINES via CpG Methylation Relieves Suppression of STAT3 and MYC, Facilitating Multiple Tumorigeneses

Advanced Science, EarlyView.
Dysregulated protein modifications drive tumorigenesis. RINES, an E3 ubiquitin ligase, represses tumor cell proliferation and metastasis by facilitating RING domain‐dependent, ubiquitin–proteasome‐mediated degradation of STAT3 and MYC, which consequently restrains cancer stemness and oncogenic progression.

The Host Cell Factor Phosphatase‐2A Subunit PR130 Restricts Replication of Herpes Simplex Virus Type‐1

Advanced Science, EarlyView.
Molecular, genetic, virological, and biochemical analysis in combination with global proteome and phosphoproteome profiling and functional assays were applied to study the role of PR130 in the context of HSV‐1 replication. The observations reveal that host‐intrinsic mechanisms regulate HSV‐1 replication and highlight PR130 as a susceptibility factor of

Mitochondrial SLC25A46 Rewires Fatty Acid Oxidation to Promote Cell Proliferation and Ferroptosis Evasion in Ovarian Cancer by Stabilizing CACT

Advanced Science, EarlyView.
Mitochondrial SLC25A46 is upregulated in ovarian cancer (OC) and correlates with poor prognosis. SLC25A46 stabilizes CACT to activate fatty acid oxidation, increasing ATP and NADPH production to drive cell proliferation and ferroptosis evasion. SLC25A46 silencing sensitizes OC cells to ferroptosis and carboplatin, offering a promising therapeutic ...

Materials‐Guided Gene‐Ionizable Lipid Nanoparticles to Reverse Iron‐Associated Immune Resistance in Renal Cancer

Advanced Science, EarlyView.
ABSTRACT Iron overload is a common metabolic disturbance in cancer and contributes to poor outcomes in renal cell carcinoma (RCC), yet its effects on the tumour immune microenvironment remain unclear. Here we identify a previously unrecognized immunosuppressive axis in which iron overload downregulates the palmitoyltransferase ZDHHC12 in CD8+ T cells ...
