The mitochondrial protease LonP1 promotes proteasome inhibitor resistance in multiple myeloma.
Bortezomib is a proteasome inhibitor used in severel different hematological malignancies. Resistance to this drug is still poorly understood. In order get more insight in the resistance mechanism, we developed several bortezomib resistant subclones of the THP-1 monocytic/macrophage cell line. On th...

Allosteric HSP70 inhibitors perturb mitochondrial proteostasis and overcome proteasome inhibitor resistance in multiple myeloma
Genome-wide analysis of gene expression in response to bortezomib treatment(33 nM) in cell lines before and after selection for resistance. Multiple myeloma (MM) is a hematologic malignancy characterized by the proliferation of neoplastic plasma cells in the bone marrow. While the first-to-market pr...

Proteasome inhibitors (PIs) are frontline therapies for multiple myeloma (MM). Although MM patients initially respond to PIs, resistance frequently emerges. While clinical PIs primarily target the same proteasomal catalytic subunit (PSMB5), the extent to which resistance mechanisms are shared among ...

Ribosomal protein S3 mediates drug resistance of proteasome inhibitor: therapeutic application in multiple myeloma
Proteasome inhibitors are important chemotherapeutics in the treatment of multiple myeloma, but they are currently used empirically as no markers of sensitivity have been validated. We have identified expression of tight junction protein (TJP) 1 as being associated with sensitivity of plasma cells ...

Despite advances in the development of direct KRAS inhibitors, KRAS-mutant cancers continue to exhibit resistance to the currently available therapies. Here, we identified REGγ as a mutant KRAS-associated factor that enhances REGγ transcription through the KRAS intermediate NRF2, suggesting that the...
