New proteasome inhibitors in the treatment of multiple myeloma

Hematology, Transfusion and Cell Therapy, 2019
The treatment of patients with relapsed and/or refractory multiple myeloma has improved considerably in the last 15 years, after the introduction of proteasome inhibitors and immunomodulatory drugs.

Proteasome Inhibitors Induce Peroxisome Proliferator-Activated Receptor Transactivation through Rxr Accumulation and a Protein Kinase C-Dependent Pathway

, 2009
Peroxisome proliferator-activated receptor γ (PPARγ), a member of nuclear hormone receptors, forms a heterodimeric DNA binding complex with retinoid X receptor (RXR) and serves as a transcriptional regulator of gene expression.

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 ...

Degradation of the LDL receptor class 2 mutants is mediated by a proteasome-dependent pathway

Journal of Lipid Research, 2004
Familial hypercholesterolemia is a genetic disorder that results from various gene mutations, primarily within the LDL receptor (LDLR). Approximately 50% of the LDLR mutations are defined as class 2 mutations, with the mutant proteins partially or ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Use of Short-Lived Green Fluorescent Protein for the Detection of Proteasome Inhibition

BioTechniques, 2001
Human embryonic kidney (HEK293) cells were stably transduced with a retroviral vector containing an expression cassette for a short-lived green fluorescent protein (d2EGFP) and the neomycin resistance gene (Neor).

Translating whole‐genome doubling into precision medicine in cancer

Molecular Oncology, EarlyView.
Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)
