Gold Nanoparticles Induced Size Dependent Cytotoxicity on Human Alveolar Adenocarcinoma Cells by Inhibiting the Ubiquitin Proteasome System

open access: yesPharmaceutics, 2023
Gold nanoparticles (AuNPs) are widely used in biomedicine due to their remarkable therapeutic applications. However, little is known about their cytotoxic effects on the ubiquitin proteasome system (UPS).

Turning-ON Proteasomes [PDF]

open access: yesCell Chemical Biology, 2017
While proteasome inhibitors are now well-established research tools and chemotherapeutics, proteasome activators are much less explored. In this issue of Cell Chemical Biology, in a study from the groups of Berkers and Ovaa (Leestemaker et al., 2017), a chemical screen was used to identify a p38 MAPK inhibitor as a proteasome activator.

Proteasome beta-4 subunit contributes to the development of melanoma and is regulated by miR-148b

open access: yesTumor Biology, 2017
The proteasome beta-4 subunit is required for the assembly of 20S proteasome complex, forming a pivotal component for the ubiquitin–proteasome system. Emerging evidence indicates that proteasome beta-4 subunit may be involved in underlying progression ...

High-Throughput/High Content Imaging Screen Identifies Novel Small Molecule Inhibitors and Immunoproteasomes as Therapeutic Targets for Chordoma

open access: yesPharmaceutics, 2023
Chordomas account for approximately 1–4% of all malignant bone tumors and 20% of primary tumors of the spinal column. It is a rare disease, with an incidence estimated to be approximately 1 per 1,000,000 people.

Role of S5b/PSMD5 in Proteasome Inhibition Caused by TNF-α/NFκB in Higher Eukaryotes

open access: yesCell Reports, 2012
The ubiquitin-proteasome system is essential for maintaining protein homeostasis. However, proteasome dysregulation in chronic diseases is poorly understood.

Hydrogen Peroxide Inhibits Hepatitis C Virus Replication by Downregulating Hepatitis C Virus Core Levels through E6-Associated Protein-Mediated Proteasomal Degradation

open access: yesCells, 2023
Hepatitis C virus (HCV) is constantly exposed to considerable oxidative stress, characterized by elevated levels of reactive oxygen species, including hydrogen peroxide (H2O2), during acute and chronic infection in the hepatocytes of patients.

Proteasome inhibitors

open access: yesBiochemical Pharmacology, 2015
Proteasome inhibitors have a 20 year history in cancer therapy. The first proteasome inhibitor, bortezomib (Velcade, PS-341), a break-through multiple myeloma treatment, moved rapidly through development from bench in 1994 to first approval in 2003. Bortezomib is a reversible boronic acid inhibitor of the chymotrypsin-like activity of the proteasome ...

Inhibitory Effect of b-AP15 on the 20S Proteasome

open access: yesBiomolecules, 2014
The 26S proteasome is a cellular proteolytic complex containing 19S regulatory particles and the 20S core proteasome. It was reported that the small molecule b-AP15 targets the proteasome by inhibiting deubiquitination of the 19S regulatory particles of
