Fluorescence-based proteasome activity profiling [PDF]

open access: yes, 2011
With the proteasome emerging as a therapeutic target for cancer treatment, accurate tools for monitoring proteasome (inhibitor) activity are in demand.

Downregulation of PA28α induces proteasome remodeling and results in resistance to proteasome inhibitors in multiple myeloma

open access: yesBlood Cancer Journal, 2020
Protein homeostasis is critical for maintaining eukaryotic cell function as well as responses to intrinsic and extrinsic stress. The proteasome is a major portion of the proteolytic machinery in mammalian cells and plays an important role in protein ...

Proteasome inhibitors alter levels of intracellular peptides in HEK293T and SH-SY5Y cells. [PDF]

open access: yesPLoS ONE, 2014
The proteasome cleaves intracellular proteins into peptides. Earlier studies found that treatment of human embryonic kidney 293T (HEK293T) cells with epoxomicin (an irreversible proteasome inhibitor) generally caused a decrease in levels of intracellular

Proteasome inhibitors as anticancer agents

open access: yes, 2023
Introduction: The therapeutic targeting of the ubiquitin-proteasome pathway (UPP) through inhibitors of the 20S proteasome core proteolytic activities has revolutionized the treatment of hematological malignancies and is paving the way for its extension ...

Structure-guided design and optimization of small molecules targeting the protein-protein interaction between the von hippel-lindau (VHL) E3 ubiquitin ligase and the hypoxia inducible factor (HIF) alpha subunit with in vitro nanomolar affinities [PDF]

open access: yes, 2014
E3 ubiquitin ligases are attractive targets in the ubiquitin-proteasome system, however, the development of small-molecule ligands has been rewarded with limited success.

Paradoxical inhibition of cellular protein expression by proteasome inhibitors

open access: yesBiomolecular Concepts, 2012
Proteasome inhibitors are used as anticancer drugs, however, the precise mechanisms of their selective activity against cancer cells are not understood well.

Autophagy-independent enhancing effects of Beclin 1 on cytotoxicity of ovarian cancer cells mediated by proteasome inhibitors

open access: yesBMC Cancer, 2012
Background The ubiquitin-proteasome system and macroautophagy (hereafter referred to autophagy) are two complementary pathways for protein degradation. Emerging evidence suggests that proteasome inhibition might be a promising approach for tumor therapy.

Regulation of TRIB1 abundance in hepatocyte models in response to proteasome inhibition

open access: yesScientific Reports, 2023
Tribbles related homolog 1 (TRIB1) contributes to lipid and glucose homeostasis by facilitating the degradation of cognate cargos by the proteasome. In view of the key metabolic role of TRIB1 and the impact of proteasome inhibition on hepatic function ...

Different effect of proteasome inhibition on vesicular stomatitis virus and poliovirus replication. [PDF]

open access: yesPLoS ONE, 2008
Proteasome activity is an important part of viral replication. In this study, we examined the effect of proteasome inhibitors on the replication of vesicular stomatitis virus (VSV) and poliovirus.

Higher ratio immune versus constitutive proteasome level as novel indicator of sensitivity of pediatric acute leukemia cells to proteasome inhibitors

open access: yesHaematologica, 2013
The ex vivo sensitivity of pediatric leukemia cells to the proteasome inhibitor bortezomib was compared to 3 next generation proteasome inhibitors: the epoxyketone-based irreversible proteasome inhibitors carfilzomib, its orally bio-available analog ONX ...
