Involvement of the ubiquitin-proteasome system in the expression of extracellular matrix genes in retinal pigment epithelial cells

Biochemistry and Biophysics Reports, 2018
Emerging evidence suggests that dysfunction of the ubiquitin-proteasome system is involved in the pathogenesis of numerous senile degenerative diseases including retinal disorders.

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

STAR 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 ...

[Retracted] Proteasome inhibitors in glioblastoma (Review)

Oncology Letters, 2017
Glioblastomas (GBM) are the tumors originating from the star shaped supportive cells in brain known as astrocytes. These tumors are highly cancerous as they have the ability to proliferate very quickly. New therapeutic strategies are being developed worldwide to fight against deadly GBM, which has median survival time of just 14 months.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

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

Nature 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 ...

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

The Broad Spectrum HDAC Inhibitor PCI-24781 Induces Caspase- and ROS-Dependent Apoptosis and is Synergistic with Bortezomib in Lymphoma [PDF]

, 2008
We investigated the cytotoxicity and biology of the novel broad-spectrum hydroxamic acid-based histone deacetylase inhibitor (HDACi), PCI-24781. PCI-24781 was studied alone and combined with bortezomib in Hodgkin lymphoma (L428) and non-Hodgkin's ...

Proteasome Inhibitors in Waldenström Macroglobulinemia

Hematology/Oncology Clinics of North America, 2018
Waldenström macroglobulinemia (WM) remains an incurable B-cell lymphoproliferative disorder, yet therapy is only considered for patients with symptomatic disease. Primary therapy options for WM include combinations based on anti-CD20 monoclonal antibodies, mainly rituximab. However, proteasome inhibitors have become an important part of WM therapy both

Inhibition of dipeptidyl peptidase 7 impairs lysophagy in LLOMe‐treated HepG2 cells

FEBS Letters, EarlyView.
DPP7 inhibition delays ubiquitin‐dependent lysophagy by attenuating ubiquitin accumulation and the recruitment of SQSTM1 and LC3 to damaged lysosomes, resulting in delayed clearance of damaged lysosomes and impaired restoration of lysosomal homeostasis. Created using FigureLabs (Certificate ID: FL‐PUB‐20260922‐Z99XNX).
