Diverse mutations and structural variations contribute to Notch signaling deregulation in paediatric T-cell lymphoblastic lymphoma. Pediatr Blood Cancer 2022; 69:e29926. [PMID: 36000950 DOI: 10.1002/pbc.29926] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/24/2022] [Accepted: 07/25/2022] [Indexed: 11/12/2022]
Abstract
BACKGROUND T-cell lymphoblastic lymphoma (T-LBL) is an aggressive neoplasm closely related to T-cell acute lymphoblastic leukaemia (T-ALL). Despite their similarities, and contrary to T-ALL, studies on paediatric T-LBL are scarce and, therefore, its molecular landscape has not yet been fully elucidated. Thus, the aims of this study were to characterize the genetic and molecular heterogeneity of paediatric T-LBL and to evaluate novel molecular markers differentiating this entity from T-ALL. PROCEDURE Thirty-three paediatric T-LBL patients were analyzed using an integrated approach, including targeted next-generation sequencing, RNA-sequencing transcriptome analysis and copy-number arrays. RESULTS Copy number and mutational analyses allowed the detection of recurrent homozygous deletions of 9p/CDKN2A (78%), trisomy 20 (19%) and gains of 17q24-q25 (16%), as well as frequent mutations of NOTCH1 (62%), followed by the BCL11B (23%), WT1 (19%) and FBXW7, PHF6 and RPL10 genes (15%, respectively). This genetic profile did not differ from that described in T-ALL in terms of mutation incidence and global genomic complexity level, but unveiled virtually exclusive 17q25 gains and trisomy 20 in T-LBL. Additionally, we identified novel gene fusions in paediatric T-LBL, including NOTCH1-IKZF2, RNGTT-SNAP91 and DDX3X-MLLT10, the last being the only one previously described in T-ALL. Moreover, clinical correlations highlighted the presence of Notch pathway alterations as a factor related to favourable outcome. CONCLUSIONS In summary, the genomic landscape of paediatric T-LBL is similar to that observed in T-ALL, and Notch signaling pathway deregulation remains the cornerstone in its pathogenesis, including not only mutations but fusion genes targeting NOTCH1.

[PMID: 32819237 DOI: 10.2174/1871520620999200818155814] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 07/19/2020] [Accepted: 07/31/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Nuclear Factor-kappa B (NF-κB) is usually activated in Wilms Tumor (WT) cells and plays a critical role in WT development. OBJECTIVE The study's purpose was to screen for a NF-κB inhibitor from the natural product library and explore its effects on WT development. METHODS Luciferase assay was employed to assess the effects of natural chemicals on NF-κB activity. CCK-8 assay was conducted to assess cell growth in response to naringenin. WT xenograft model was established to analyze the effect of naringenin in vivo. Quantitative real-time PCR and Western blot were performed to examine the mRNA and protein levels of relative genes, respectively. RESULTS Naringenin displayed a significant inhibitory effect on NF-κB activation in SK-NEP-1 cells. In SKNEP- 1 and G-401 cells, naringenin inhibited p65 phosphorylation. Moreover, naringenin suppressed TNF-α- induced p65 phosphorylation in WT cells. Naringenin inhibited TLR4 expression at both mRNA and protein levels in WT cells. CCK-8 staining showed that naringenin inhibited cell growth of the two above WT cells in doseand time-dependent manner, whereas Toll-Like Receptor 4 (TLR4) overexpression partially reversed the above phenomena. Besides, naringenin suppressed WT tumor growth in a dose- and time-dependent manner in vivo. Western blot found that naringenin inhibited TLR4 expression and p65 phosphorylation in WT xenograft tumors. CONCLUSION Naringenin inhibits WT development via suppressing TLR4/NF-κB signaling.

Salidroside inhibits the growth, migration and invasion of Wilms' tumor cells through down-regulation of miR-891b. Life Sci 2019; 222:60-68. [PMID: 30822424 DOI: 10.1016/j.lfs.2019.02.052] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Revised: 02/18/2019] [Accepted: 02/25/2019] [Indexed: 11/20/2022]
Abstract
AIMS Salidroside is a major functional component of Rhodiola rosea L. with a lot of pharmacological effects, including anti-tumor. The present work aimed to explore whether Salidroside could also exhibit anti-tumor functions in Wilms' tumor. MAIN METHODS WIT49 and RM1 cells were treated by various doses of Salidroside. CCK-8 assay, flow cytometry detection, colony formation assay, Transwell assay, RT-qPCR and Western blot analysis were conducted to measure WIT49 and RM1 cells proliferation, apoptosis, migration and invasion. The expression changes of miR-891b in response to Salidroside treatment were tested by RT-qPCR. Rescue assays were performed to test whether miR-891b was a downstream effector of Salidroside. Finally, the involvement of PI3K/AKT/mTOR and NF-κB signaling pathways was studied. KEY FINDINGS Salidroside with concentration of 80 μM significantly reduced WIT49 and RM1 cells viability, survival capacity, migration and invasion, and significantly induced apoptosis. Meanwhile, down-regulation of Cyclin D1, MMP-2 and Vimentin, up-regulations of p53 and p21, as well as cleavage of caspase-3 and -9 were observed in Salidroside-treated cell. miR-891b was down-regulated by Salidroside. And Salidroside did not suppress WIT49 and RM1 cells growth, migration and invasion when miR-891b was overexpressed. Also, the deactivation of PI3K/AKT/mTOR and NF-κB pathways induced by Salidroside was reversed by miR-891b overexpression. SIGNIFICANCE Salidroside inhibits Wilms' tumor cells growth, migration and invasion via down-regulating miR-891b, which leads to the deactivation of PI3K/AKT/mTOR and NF-κB signaling pathways.

The role of NF-κB signaling in the maintenance of pluripotency of human induced pluripotent stem cells. PLoS One 2013; 8:e56399. [PMID: 23437124 PMCID: PMC3577895 DOI: 10.1371/journal.pone.0056399] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2012] [Accepted: 01/09/2013] [Indexed: 12/24/2022] Open
Abstract
NF-κB signaling plays an essential role in maintaining the undifferentiated state of embryonic stem (ES) cells. However, opposing roles of NF-κB have been reported in mouse and human ES cells, and the role of NF-κB in human induced pluripotent stem (iPS) cells has not yet been clarified. Here, we report the role of NF-κB signaling in maintaining the undifferentiated state of human iPS cells. Compared with differentiated cells, undifferentiated human iPS cells showed an augmentation of NF-κB activity. During differentiation induced by the removal of feeder cells and FGF2, we observed a reduction in NF-κB activity, the expression of the undifferentiation markers Oct3/4 and Nanog, and the up-regulation of the differentiated markers WT-1 and Pax-2. The specific knockdown of NF-κB signaling using p65 siRNA also reduced the expression of Oct3/4 and Nanog and up-regulated WT-1 and Pax-2 but did not change the ES-like colony formation. Our results show that the augmentation of NF-κB signaling maintains the undifferentiated state of human iPS and suggest the importance of this signaling pathway in maintenance of human iPS cells.
