Abstract
Bruton’s tyrosine kinase (BTK) is a proven target in mantle cell lymphoma (MCL), an aggressive subtype of non-Hodgkin lymphoma. However, resistance to BTK inhibitors is a major clinical challenge. We here report that MALT1 is one of the top overexpressed genes in ibrutinib-resistant MCL cells, while expression of CARD11, which is upstream of MALT1, is decreased. MALT1 genetic knockout or inhibition produced dramatic defects in MCL cell growth regardless of ibrutinib sensitivity. Conversely, CARD11 knockout cells showed anti-tumor effects only in ibrutinib-sensitive cells, suggesting that MALT1 overexpression could drive ibrutinib resistance via bypassing BTK-CARD11 signaling. Additionally, BTK knockdown and MALT1 knockout markedly impaired MCL tumor migration and dissemination, and MALT1 pharmacological inhibition decreased MCL cell viability, adhesion, and migration by suppressing NF-κB, PI3K-ATK-mTOR, and integrin signaling. Importantly, co-targeting MALT1 with safimaltib and BTK with pirtobrutinib induced potent anti-MCL activity in ibrutinib-resistant MCL cell lines and patient-derived xenografts. Therefore, we conclude that MALT1 overexpression associates with resistance to BTK inhibitors in MCL, targeting abnormal MALT1 activity could be a promising therapeutic strategy to overcome BTK inhibitor resistance, and co-targeting of MALT1 and BTK should improve MCL treatment efficacy and durability as well as patient outcomes.

Project description:Patients with conventional mantle cell lymphoma (MCL) show an aggressive clinical behavior. However, cases fulfilling the WHO criteria for MCL, but that remain asymptomatic without treatment, have been reported. In an attempt to understand this heterogeneity, we have compared 17 typical cases of MCL with a homogeneous group of 13 asymptomatic individuals with monoclonal expansion of t(11;14)(q13;q32) cyclin D1-positive B-cells in peripheral blood (MALD1). None of these cases have received treatment (minimum follow-up of 26 months; median, 71 months). Gene expression analysis has shown enrichment of signatures associated to neoplastic behavior and cell proliferation in MCL but not in MALD1. In contrast, MALD1 was highly enriched in gene sets related to immune activation and inflammatory responses. CD38 and CD200 genes were differentially expressed between MCL and MALD1. The combined assessment of both proteins by flow cytometry allowed classifying 85% of MALD1 cases. In summary, we have shown for the first time that MALD1, in contrast to MCL, is characterized by immune activation and driven by inflammatory cues. We have also shown that CD38 and CD200 flow cytometry assessment is useful to discern most cases of MALD1 from MCL in the clinical setting. MALD1 should be identified and segregated from the current MCL category to avoid overdiagnosis and unnecessary treatment.

Project description:MicroRNAs (miRNAs) have important roles in gene regulation. Dysregulation of miRNAs has been associated with tumorigenesis. Recent studies suggest miR-193b is a tumor suppressor gene. In a previous study, we reported that miR-193b represses cell proliferation and regulates cyclin D1 (CCND1) in melanoma. Now we demonstrate that miR-193b regulates myeloid cell leukemia sequence 1 (Mcl-1) in melanoma cells. miRNA microarray profiling revealed the miR-193b level in malignant melanomas was significantly downregulated compared to benign nevi, while a tissue microarray demonstrated overexpression of Mcl-1 in malignant melanoma. The Mcl-1 expressions were inversely correlated with the miR-193b levels in melanoma tissue samples, suggesting a potential regulatory role of miR-193b. Overexpression of miR-193b repressed Mcl-1 in melanoma cell lines. It is well known that Mcl-1 knockdown confers cell sensitivity to ABT-737, a small molecular inhibitor of Bcl-2, Bcl-XL and Bcl-w. We found miR-193b, through repressing Mcl-1 expression, could also sensitize melanoma cells that were refractory to ABT-737. Furthermore, miR-193b directly regulates Mcl-1 by targeting the 3’ untranslated region (3’UTR) of Mcl-1 mRNA. Interestingly, miR-193b may recognize sequences on the 3’UTR that do not base pair with its seed region. In conclusion, our study suggests the downregulation of miR-193b could be an early event during melanoma progression, and demonstrates miR-193b directly regulates Mcl-1 by targeting both seed and seedless sequences of the 3’ UTR.

Project description:Mantle cell lymphoma (MCL) is a lymphoma characterized by aberrant activation of CCND1/cyclin D1 followed by sequential genetic abnormalities. Genomic abnormalities in MCL have been extensively examined by classical cytogenetics and microarray-based comparative genomic hybridization techniques, pointing out a number of alterations in genomic regions that correlate with the neoplastic phenotype and survival. Recently, single nucleotide polymorphism genomic microarrays (SNP-chip) have been developed and used for analysis of cancer genomics. This technique allows detection of genomic changes with higher resolution, including loss of heterozygosity without changes of gene dosage, so-called acquired uniparental disomy (aUPD). As a result of the analysis, known alterations were confirmed by SNP arrays, including deletion of INK4A/ARF, duplication/amplification of MYC, deletion of ATM, and deletion of TP53. We also identified a duplication/amplification that occurred at 13q involving oncogenic microRNA, miR17-92. We found other genomic abnormalities, including duplication/amplification of cyclin D1, del(1p), del(6q), dup(3q) and dup(18q). Our SNP-chip analysis detected these abnormalities at high resolution, allowing us to narrow the size of the commonly deleted regions, including 1p and 6q. Our SNP-chip analysis detected a number of aUPD sites, including whole chromosome 9 aUPD and 9p aUPD. We also found an MCL case with 19p, leading to homozygous deletion of TNFSF genes. keyword: SNP-chip; Kawmata_MCL
