Enhancing the Effectiveness of Chemotherapy in Osteosarcoma by Targeting Tumour‐Associated Macrophages (TAMs) through STING Activation

Advanced Therapeutics, EarlyView.
Osteosarcoma isa highly aggressive bone cancer with an immunosuppressive tumor microenvironment that limits immunotherapy. This study explores STING pathway activation to reprogram tumor‐associated macrophages into a tumoricidal M1‐like phenotype and enhance doxorubicin efficacy. Results show that doxorubicin alone failed to activate the STING pathway,

Mechanism of cullin3 E3 ubiquitin ligase dimerization. [PDF]

PLoS ONE, 2012
Cullin E3 ligases are the largest family of ubiquitin ligases with diverse cellular functions. One of seven cullin proteins serves as a scaffold protein for the assembly of the multisubunit ubiquitin ligase complex.

Age-related deficits in skeletal muscle recovery following disuse are associated with neuromuscular junction instability and ER stress, not impaired protein synthesis. [PDF]

, 2016
Age-related loss of muscle mass and strength can be accelerated by impaired recovery of muscle mass following a transient atrophic stimulus. The aim of this study was to identify the mechanisms underlying the attenuated recovery of muscle mass and ...

NAD+‐Boosters Improve Mitochondria Quality Control In Parkinson's Disease Models Via Mitochondrial UPR

Advanced Science, EarlyView.
Treatment of MPTP‐incubated cells with NAD+‐boosters increase the UPRmt/mitophagy‐related mitochondria quality control (MQC). Disturbed plasma UPRmt‐mitophagy‐mediated MQC profiles in PD patient samples. NMN inhibits motor deficit and forestalls neuropathology phenotypes of PD mice, which is required the atf4‐medicated UPRmt pathway.

E3 Ubiquitin Ligases: Potential Therapeutic Targets for Skeletal Pathology and Degeneration

Stem Cells International, 2022
The ubiquitination-proteasome system (UPS) is crucial in regulating a variety of cellular processes including proliferation, differentiation, and survival. Ubiquitin protein ligase E3 is the most critical molecule in the UPS system.

Coupled monoubiquitylation of the co-E3 ligase DCNL1 by Ariadne RBR E3 ubiquitin ligases promotes cullin-RING ligase complex remodeling [PDF]

, 2019
Cullin-RING E3 ubiquitin ligases (CRLs) are large and diverse multisubunit protein complexes that contribute to about one-fifth of ubiquitin-dependent protein turnover in cells.

Ubiquitination and Degradation of the Substrate Recognition Subunits of SCF Ubiquitin–Protein Ligases [PDF]

Molecular Cell, 1998
The S. cerevisiae SCFCdc4p ubiquitin-protein ligase complex promotes cell cycle transitions through degradation of cell cycle regulators. To investigate SCFCdc4p regulation in vivo, we examined the stability of individual SCFCdc4p components. Whereas Cdc53p and Skp1p were stable, Cdc4p, the F box-containing component responsible for substrate ...

Branched‐Chain α Keto‐Acid Dehydrogenase Kinase‐Mediated AKT Phosphorylation Promotes RCC Tumorigenesis and Drug Resistance

Advanced Science, EarlyView.
This study identifies a novel oncogenic role and a previously unrecognized phosphorylation substrate of BCKDK in RCC, wherein it promotes tumor progression and drug resistance through AKT phosphorylation at both Thr308 and Ser473 sites and activation of AKT/mTOR and AKT/ABCB1 signaling pathways, offering a promising prognostic marker and therapeutic ...

Subcellular organization of UBE3A in human cerebral cortex. [PDF]

, 2018
BackgroundLoss of UBE3A causes Angelman syndrome, whereas excess UBE3A activity appears to increase the risk for autism. Despite this powerful association with neurodevelopmental disorders, there is still much to be learned about UBE3A, including its ...
