Protocol for analysis of intracellular conversion of artezomib molecules into new proteasome inhibitors in Plasmodium falciparum parasites

open access: yesSTAR Protocols
Summary: Artezomibs (ATZs), dual-pharmacophore molecules comprising of artemisinin and a parasite proteasome inhibitor, hijack parasite ubiquitin proteasome system to transform into new proteasome inhibitors following the activation of artemisinin by ...

Evaluation of melanin-targeted radiotherapy in combination with radiosensitizing drugs for the treatment of melanoma [PDF]

open access: yes, 2014
The incidence of malignant melanoma is rising faster than that of any other cancer in the United States. An [131I]-labeled benzamide - [131I]MIP-1145 - selectively targets melanin, reduces melanoma tumor burden and increases survival in preclinical ...

Assessment of the direct and indirect effects of MPP+ and dopamine on the human proteasome: implications for Parkinson's disease aetiology [PDF]

open access: yes, 2008
Mitochondrial impairment, glutathione depletion and oxidative stress have been implicated in the pathogenesis of Parkinson’s disease (PD), linked recently to proteasomal dysfunction.

The deubiquitinase OTUD1 regulates immunoglobulin production and proteasome inhibitor sensitivity in multiple myeloma

open access: yesNature Communications, 2022
Development of proteasome inhibitor resistance is a common problem in patients with multiple myeloma. Here, the authors show that deubiquitinase OTUD1 protects PRDX4 from degradation resulting in increased load of misfolded immunoglobulins sensitizing ...

Mifepristone increases mRNA translation rate, triggers the unfolded protein response, increases autophagic flux, and kills ovarian cancer cells in combination with proteasome or lysosome inhibitors [PDF]

open access: yes, 2016
The synthetic steroid mifepristone blocks the growth of ovarian cancer cells, yet the mechanism driving such effect is not entirely understood. Unbiased genomic and proteomic screenings using ovarian cancer cell lines of different genetic backgrounds and

Natural killer cell response to chemotherapy-stressed cancer cells: Role in tumor immunosurveillance. [PDF]

open access: yes, 2017
Natural killer (NK) cells are innate cytotoxic lymphoid cells that actively prevent neoplastic development, growth, and metastatic dissemination in a process called cancer immunosurveillance.

The proteasome cap RPT5/Rpt5p subunit prevents aggregation of unfolded ricin A chain [PDF]

open access: yes, 2013
The plant cytotoxin ricin enters mammalian cells by receptor-mediated endocytosis, undergoing retrograde transport to the endoplasmic reticulum (ER) where its catalytic A chain (RTA) is reductively separated from the holotoxin to enter the cytosol and ...

Semaphorin-3A Promotes Degradation of Fragile X Mental Retardation Protein in Growth Cones via the Ubiquitin-Proteasome Pathway

open access: yesFrontiers in Neural Circuits, 2020
Fragile X mental retardation protein (FMRP) is an RNA-binding protein that regulates local translation in dendrites and spines for synaptic plasticity. In axons, FMRP is implicated in axonal extension and axon guidance.

Components of the ubiquitin-proteasome pathway compete for surfaces on Rad23 family proteins [PDF]

open access: yes, 2008
Background: The delivery of ubiquitinated proteins to the proteasome for degradation is a key step in the regulation of the ubiquitin-proteasome pathway, yet the mechanisms underlying this step are not understood in detail.

Histone deacetylase 2 is phosphorylated, ubiquitinated, and degraded by cigarette smoke [PDF]

open access: yes, 2008
Cigarette smoke (CS)–induced lung inflammation involves the reduction of histone deacetylase 2 (HDAC2) abundance, which is associated with steroid resistance in patients with chronic obstructive pulmonary disease and in individuals with severe asthma who
