Project description:The precise molecular mechanism of action and targets through which thalidomide and related immunomodulatory drugs (IMiDs) exert their anti-tumor effects remains unclear. We investigated the role of cereblon (CRBN), a primary teratogenic target of thalidomide, in the anti-myeloma activity of IMiDs. CRBN depletion is initially cytotoxic to human myeloma cells but surviving cells with stable CRBN depletion become highly resistant to both lenalidomide and pomalidomide, but not to the unrelated drugs bortezomib, dexamethasone and melphalan. Acquired deletion of CRBN was found to be the primary genetic event differentiating isogenic MM1.S cell lines cultured to be sensitive or resistant to lenalidomide and pomalidomide. Gene expression changes induced by lenalidomide were dramatically suppressed in the presence of CRBN depletion further demonstrating that CRBN is required for lenalidomide activity. Downstream targets of CRBN include interferon regulatory factor 4 (IRF4) previously reported to also be a target of lenalidomide. Patients exposed to and putatively resistant to lenalidomide had lower CRBN levels in paired samples before and after therapy. In summary, CRBN is an essential requirement for IMiD activity, and a possible biomarker for the clinical assessment of anti-myeloma efficacy. We included 15 samples from multiple myeloma cell lines.

We included two isogenic MM1.S cell lines, which differ in the sensibiligy to lenalidomide. We included MM1.S and MM1.S res, which were sensitive and resistant to lenalidomide, respectively.

Project description:Multiple myeloma is a genetically heterogeneous disease of plasma cells. The thalidomide analog lenalidomide is a mainstay in the treatment of multiple myeloma and is used in combination with other drugs such as corticosteroids, chemotherapy and proteasome inhibitors, achieving high remission rates. However, most patients relapse due to acquired resistance of the malignant cells. Genetic analyses have revealed mutations in CRBN, the target of all IMiDs, as a resistance mechanism in 10% of patients, while for the majority of cases, the mechanism of resistance is unknown. Here, we performed integrated global quantitative tandem mass tag (TMT)-based proteomic and phosphoproteomic analyses and RNA sequencing in five paired pre-treatment and relapse samples from multiple myeloma patients. These analyses revealed proteins highly upregulated at relapse, including TRIP13, RRM1 and CDK6, which was not reflected on the RNA expression level. Overexpression of CDK6 in multiple myeloma cell lines reduced sensitivity to lenalidomide and pomalidomide in a kinase-dependent fashion. CDK6 inactivation by palbociclib or a CDK6-specific proteolysis targeting chimera (PROTAC) plus lenalidomide or pomalidomide was highly synergistic. Proteomic analyses in cell lines revealed that CDK6 inhibition reverses a complex protein resistance signature including RRM1 and TRIP13 and in combination with IMiDs promotes metabolic remodeling and c-MYC downregulation . In conclusion, our global proteomic analyses identified CDK6 upregulation as a drug target to overcome lenalidomide resistance in multiple myeloma.

Thalidomide, infamous for its teratogenic effects, and derivatives lenalidomide and pomalidomide have found new clinical utility as treatments for multiple myeloma and myelodysplastic syndrome with del(5q). Despite their widespread clinical use, studies of these drugs have been limited by their lack of effect in rodent models. Here, we report the development of a knock-in mouse that is sensitive to thalidomide derivatives. Thalidomide analogs bind to CRBN and recruit protein targets to the CRL4CRBN E3 ubiquitin ligase, resulting in their ubiquitination and subsequent degradation by the proteasome. Mice with a single amino acid change in Crbn, CrbnI391V, have thalidomide-induced degradation of drug targets identified in human cells including Ikaros, Aiolos, Zfp91, and Ck1-alpha. Previous work suggested that haploinsufficient expression of Ck1-alpha could explain the efficacy of lenalidomide in del(5q) myelodysplastic syndrome. Using the CrbnI391V model, we demonstrate that haploinsufficiency for Ck1-alpha confers lenalidomide sensitivity in vivo and that both lenalidomide-induced selection and Trp53-mediated resistance occur at the level of hematopoietic stem cells. We also demonstrate that CrbnI391V is sufficient to confer thalidomide-induced fetal loss in mice. Further study of the CrbnI391V model will provide valuable insights into the in vivo efficacy and toxicity of this class of drugs.

Project description:Lenalidomide, an analogue of thalidomide, is immuno-modulatory drug and has been used for many types of cancer therapy. Recently, it has been reported that lenalidomide can enhance the function of NK cell during IL-2 response. However, molecular mechanism of action of lenalidomide in NK cells is unclear still. To investigate the modification by lenalidomide on NK cells, we conducted the analysis of gene expression on NK cells.

Project description:A major pharmacological strategy toward HIV cure aims to reverse latency in infected cells as a first step leading to their elimination. While the unbiased identification of molecular targets physically associated with the latent HIV-1 provirus would be highly valuable to unravel the molecular determinants of HIV-1 transcriptional repression and latency reversal, due to technical limitations, this has been challenging. Here we use a dCas9 targeted chromatin and histone enrichment strategy coupled to mass spectrometry (Catchet-MS) to probe the differential protein composition of the latent and activated HIV-1 5'LTR. Catchet-MS identified known and novel latent 5’LTR-associated host factors. Among these, IKZF1 is a novel HIV-1 transcriptional repressor, required for Polycomb Repressive Complex 2 recruitment to the LTR. We find the clinically advanced thalidomide analogue iberdomide, and the FDA approved analogues lenalidomide and pomalidomide, to be novel LRAs that, by targeting IKZF1 for degradation, reverse HIV-1 latency in CD4+T-cells isolated from virally suppressed people living with HIV-1.
