Project description:Neuroblastoma accounts for 15% of cancer-related deaths in children, highlighting an unmet need for novel therapies. Selinexor is a small molecule inhibitor of XPO1 that shuffles cargo proteins with a nuclear export sequence, many of which are essential for cancer growth and cell maintenance, from the nucleus to the cytosol. We systematically tested the effect of selinexor against neuroblastoma cells in vitro and in vivo and used a proteomics screening approach to interrogate unknown mechanisms of action. We found that selinexor induces its cytotoxic effects in neuroblastoma through the nuclear accumulation of p53. By combining selinexor with an aurora kinase inhibitor, alisertib that is already in clinical use for neuroblastoma, we show that p53-mediated lethality can be further augmented supporting clinical testing of this drug combination against neuroblastoma

Project description:Inhibition of BCR signaling through BTK inhibitor, ibrutinib, has generated a remarkable response in mantle cell lymphoma (MCL). However, approximately one-third of the patients do not respond well to the drug and disease relapse on ibrutinib is nearly universal. Alternative therapeutic strategies aimed to prevent and overcome ibrutinib resistance are needed. We compared and contrasted the effects of selinexor, a selective inhibitor of nuclear export, with ibrutinib in six MCL cell lines that display differential intrinsic sensitivity to ibrutinib. We found that selinexor had a broader anti-tumor activity in MCL than ibrutinib. MCL cell lines resistant to ibrutinib remained sensitive to selinexor. We showed that selinexor induced apoptosis/cell cycle arrest and XPO-1 knockdown also retarded cell growth. Further, down-regulation of the NF-B gene signature, as opposed to BCR signature, was a common feature that underlies the response of MCL to both selinexor and ibrutinib. Meanwhile, unaltered NF-B was associated with ibrutinib resistance. Mechnistically, selinexor induced nuclear retention of IB that was accompanied by the reduction of DNA binding activity of NF-B suggesting that NF-B is trapped in an inhibitory complex. Co-immunoprecipitation confirmed that p65 of NF-B and IB were physically associated. In primary MCL tumors, we further demonstrated that the number of cells with IB nuclear retention was linearly correlated with the degree of apoptosis. Our data highlight the role of NF-B pathway in drug response to ibrutinib and selinexor and show the potential of using selinexor to prevent and overcome intrinsic ibrutinib resistance through NF-B inhibition.

Project description:Wilms tumor (WT) is the most common renal malignancy of childhood. Despite improvements in the overall survival, relapse occurs in ~15% of patients with favorable histology WT (FHWT). Half of these patients will succumb to their disease. Identifying novel targeted therapies in a systematic manner remains challenging in part due to the lack of faithful preclinical in vitro models. We established ten short-term patient-derived WT cell lines and characterized these models using low-coverage whole genome sequencing, whole exome sequencing and RNA-sequencing, which demonstrated that these ex-vivo models faithfully recapitulate WT biology. We then performed targeted RNAi and CRISPR-Cas9 loss-of-function screens and identified the nuclear export genes (XPO1 and KPNB1) as strong vulnerabilities. We observed that these models are sensitive to nuclear export inhibition using the FDA approved therapeutic agent, selinexor (KPT-330). Selinexor treatment of FHWT suppressed TRIP13 expression, which was required for survival. We further identified in vitro and in vivo synergy between selinexor and doxorubicin, a chemotherapy used in high risk FHWT. Taken together, we identified XPO1 inhibition with selinexor as a potential therapeutic option to treat FHWTs and in combination with doxorubicin, leads to durable remissions in vivo.

Project description:Selinexor is an orally bioavailable, small-molecule selective inhibitor of nuclear export protein that has been approved for the clinical treatment of relapsed or refractory multiple myeloma. At present, some studies have found that Selinexor can play an anti-inflammatory role in sepsis. We found that Selinexor, a selective inhibitor of XPO1, can alleviate bleomycin-induced pulmonary fibrosis in mice in our research work, but the specific mechanism is still unclear. After Selinexor treatment of bleomycin-induced pulmonary fibrosis in mice, we detected some differentially expressed proteins through proteomics, which may be the key mechanism of alleviating pulmonary fibrosis.

Project description:SF3B1 mutations are the most frequent spliceosomal alterations across cancers, yet no successful therapy exists to target this pathway. Previous findings from a phase 2 clinical trial of the XPO1 inhibitor selinexor in patients with high-risk myelodysplastic neoplasms (MDS) relapsed or refractory to hypomethylating agents (HMA) revealed increased activity in patients with SF3B1 mutations. XPO1 (Exportin-1) is responsible for the export of over 200 proteins, but also plays a role in the transport of multiple RNA species, including small nuclear RNAs (snRNAs), ribosomal RNAs (rRNAs), and select messenger RNAs (mRNAs) out of the nucleus. We therefore hypothesized that XPO1 inhibition perturbs RNA export and may preferentially affect SF3B1 mutants via altered splicing, given the role of XPO1 in exporting snRNAs, which form the catalytic portion of the spliceosome. To evaluate the mechanism underlying preferentially sensitivity of SF3B1-mutants to XPO1 inhibition, we performed nuclear and cytoplasmic fraction followed by RNA sequencing before and after XPO1 inhibition in SF3B1 wildtype and SF3B1 K666N cells (subcellular RNA-seq). Whole transcriptomic analysis of subcellular RNA-seq data revealed more nuclear retention of global RNA transcripts after XPO1 inhibition in the SF3B1 mutant cell line. Similarly, we performed subcellular RNA-seq for small RNAs and found snRNAs to be increased in the nucleus after XPO1 inhibition in the SF3B1 mutant cells. We then performed total cellular RNA sequencing to understand the effect of XPO1 inhibition on global RNA expression and RNA splicing. Differential gene expression analysis identified that XPO1 inhibition had the greatest effect on cell cycle in SF3B1 wildtype cells but in SF3B1-mutant cells differentiation pathways were more significantly affected. Alternative splicing analysis showed increased 3’ alternative splicing events in SF3B1 mutant after XPO1 inhibition. These results signify the mechanistic basis for preferential sensitivity of SF3B1 mutant cells to nuclear export inhibition arises through nuclear retention of spliceosomal snRNAs and select mRNAs that result in perturbation of differentiation pathways.
