Astrocytic LMP2 Coordinates NF‐κB and TGF‐β1/Smad3 Signaling to Drive Neuroinflammation after Cerebral Ischemia/Reperfusion

open access: yesAdvanced Science, EarlyView.
ABSTRACT Astrocyte reactivity critically shapes neuroinflammatory outcomes after ischemic stroke, yet the upstream regulators governing astrocyte state transitions remain incompletely defined. Here, we identify the immunoproteasome subunit low molecular weight protein 2 (LMP2) as an important modulator of astrocyte functional remodeling following ...

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

open access: yesAdvanced 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

open access: yesAdvanced 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 ...

Hepatocellular carcinoma and the ubiquitin–proteasome system [PDF]

open access: yes, 2008
Hepatocellular carcinoma is one of the largest causes of cancer-related deaths worldwide for which there are very limited treatment options that are currently effective. The ubiquitin–proteasome system has rapidly become acknowledged as both critical for

The role of the ubiquitin proteasome system in lymphoma

open access: yesCritical Reviews in Oncology/Hematology, 2013
The ubiquitin-proteasome system (UPS) maintains the integrity of cellular processes by controlling protein degradation pathways. The role of the UPS in proliferation, cell cycle, differentiation, DNA repair, protein folding, and apoptosis is well documented, and a wide range of protein activities in these signaling pathways can be manipulated by UPS ...

ZDHHC18‐Mediated Palmitoylation of ORF3a Promotes SARS‐CoV‐2 Pathogenesis by Antagonizing TRIM16‐Mediated Ubiquitination and Proteasomal Degradation

open access: yesAdvanced Science, EarlyView.
Palmitoylation by ZDHHC18 blocks ORF3a K27‐linked ubiquitination mediated by TRIM16, thereby preventing its proteasomal degradation and strengthening viral pathogenesis. Targeting palmitoylation through a pharmacological inhibitor (2‐BP), a competitive inhibitory peptide (OPIP), or adenovirus‐mediated knockdown of ZDHHC18 expression presents a ...

Proteasome-associated HECT-type ubiquitin ligase activity is required for plant immunity.

open access: yesPLoS Pathogens, 2018
Regulated degradation of proteins by the 26S proteasome plays important roles in maintenance and signalling in eukaryotic cells. Proteins are marked for degradation by the action of E3 ligases that site-specifically modify their substrates by adding ...

Lactoferrin Deficiency During Lactation Causes Adult Obesity‐Related Metabolic Disease Through Persistent Adipose Dysfunction Driven by Impaired Adipocyte Development

open access: yesAdvanced Science, EarlyView.
Lactational lactoferrin deficiency exerts lasting effects on epididymal adipose tissue development from lactation into adulthood: it impairs adipocyte hyperplasia and induces pathological hypertrophy, resulting in lower body weight yet exacerbated metabolic dysfunction under a high‐fat diet in adulthood.
