Abstract
Neural precursor cell-expressed developmentally downregulated gene 4 (NEDD4) is an E3 ubiquitin ligase that recognizes substrates via protein-protein interactions and takes part in tumor development. This study aims to clarify NEDD4's functions in diffuse large B-cell lymphoma (DLBCL) and its downstream mechanisms. Collection of 53 DLBCL tissues and adjacent normal lymphoid tissues, and detection of NEDD4 and Forkhead box protein A1 (FOXA1) in the tissues were conducted. The selection of DLBCL cells was for FARAGE, and test of cells' advancement was after transfection. Analysis of NEDD4 and FOXA1's link, and test of Wnt/β-catenin pathway were implemented. In vivo tumor xenograft experiments were put into effect. Detection of the pathological conditions of tumor tissues and the positive Ki67 in the family was implemented. It came out NEDD4 was reduced in DLBCL tissues and cell lines, and FOXA1 was elevated; Enhancing NEDD4 or repressing FOXA1 refrained DLBCL cells' advancement; NEDD4 could combine with FOXA1 and trigger its ubiquitination and degradation; NEDD4 inactivates the Wnt/β-catenin pathway by motivating FOXA1 ubiquitination; NEDD4 enhancement refrained DLBCL growth in vivo. In conclusion, the E3 ubiquitin ligase NEDD4 accelerates FOXA1 ubiquitination but refrains DLBCL cell proliferation via the Wnt/β-Catenin pathway.

Abstract
Diffuse large B-cell lymphoma (DLBCL) originates from B lymphocytes and is a fatal hematological malignancy. Circular RNAs have been increasingly reported as a promising biological target for cancer therapy, but their role in DLBCL remains poorly studied. Relative expression levels of has_circ_0000877 (circ_0000877), microRNA-370-3p (miR-370-3p), and mitogen-activated protein kinase kinase kinase kinase 4 (MAP4K4) were assessed by quantitative real-time PCR. Western blot analysis was employed to measure protein levels. Cell Counting Kit-8 assay and 5-ethynyl-2'-deoxyuridine (EdU) assay were used to detect the proliferation of TMD8 and U2932 cells. Cell cycle and apoptosis were investigated by flow cytometry. Transwell assay was used to analyze cell migration and invasion. Molecular interaction was determined by dual-luciferase reporter assay and RNA immunoprecipitation assay. The protein expression of Ki67 in tumor tissues of mice was detected by immunohistochemistry assay. The expression of circ_0000877 was markedly elevated in DLBCL tissues and cell lines. The decreased expression of circ_0000877 significantly inhibited proliferation, migration, and invasion of DLBCL cell lines. In addition, silencing circ_0000877 promoted cell apoptosis and induced cell cycle arrest in G0/G1 phase. Then, miR-370-3p directly interacted with circ_0000877 and MAP4K4. Circ_0000877 promoted MAP4K4 level by sponging miR-370-3p. MAP4K4 depletion inhibited the activation of Hippo pathway. Finally, circ_0000877 silencing significantly prevented the growth of DLBCL cells in vivo . Our findings revealed that circ_0000877 could regulate the malignant evolution of DLBCL by miR-370-3p/MAP4K4/Hippo pathway.

Abstract
B-cell development is a very orchestrated pathway that involves several molecules, such as transcription factors, cytokines, microRNAs, and also different cells. All these components maintain the ideal microenvironment and control B-cell differentiation. MicroRNAs are small non-coding RNAs that bind to target mRNA to control gene expression. These molecules could circulate in the body in a free form, protein-bounded, or encapsulated into extracellular vesicles, such as exosomes. The comprehension of the role of microRNAs in the B-cell development was possible based on microRNA profile of each B-cell stage and functional studies. Herein, we report the knowledge about microRNAs in the B-cell the differentiation, proliferation, and also in hematological malignancies.

Leuk Res 2022; 112:106769. [PMID: 34875555 DOI: 10.1016/j.leukres.2021.106769] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 11/05/2021] [Accepted: 11/28/2021] [Indexed: 10/19/2022]
Abstract
Diffuse large B cell lymphoma (DLBCL), the most common type of non-Hodgkin lymphoma worldwide, is aggressive and highly heterogeneous. MiR-665 was found to be lowly expressed in serum exosomes of DLBCL patients and in DLBCL cell lines, but its function in DLBCL progression remains unclear. In this study, miR-665 was overexpressed in SU-DHL-4 cells via miR-665 mimics and knocked down in FARAGE cells via miR-665 inhibitor. Knockdown of miR-665 promoted DLBCL cell proliferation and invasion and decreased cell apoptosis, whereas miR-665 overexpression showed opposite effects on DLBCL cell malignant behaviors. Luciferase reporter assay confirmed LIM and SH3 protein 1 (LASP1) and MYC as target genes of miR-665. Moreover, the expression of LASP1 was negatively correlated with that of miR-665 in LDLBCL cells. LASP1 has tumor-promoting property and its inhibition abolished the effect of miR-665 knockdown on DLBCL cell proliferation, invasion, and apoptosis. SU-DHL-4 cells were inoculated into the flank of nude mice, followed by orthotopic injection with miR-665 agomir. MiR-665 overexpression restricted tumor growth in vivo. Thus, we demonstrates that miR-665 suppresses DLBCL cell malignant behaviors by inhibiting cell proliferation and invasion and inducing apoptosis via targeting LASP1 and MYC, suggesting the importance of miR-665 in DLBCL progression.

Diagnostics (Basel) 2021; 11:1739. [PMID: 34679437 PMCID: PMC8535125 DOI: 10.3390/diagnostics11101739] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 09/10/2021] [Accepted: 09/17/2021] [Indexed: 11/16/2022] Open
Abstract
MicroRNA is a small non-coding RNA (sncRNA) involved in gene silencing and regulating post-transcriptional gene expression. miRNAs play an essential role in the pathogenesis of numerous diseases, including diabetes, cardiovascular diseases, viral diseases and cancer. Diffuse large B-cell lymphoma (DLBCL) is an aggressive non-Hodgkin's lymphoma (NHL), arising from different stages of B-cell differentiation whose pathogenesis involves miRNAs. Various viral and non-viral vectors are used as a delivery vehicle for introducing specific miRNA inside the cell. Adenoviruses are linear, double-stranded DNA viruses with 35 kb genome size and are extensively used in gene therapy. Meanwhile, Adeno-associated viruses accommodate up to 4.8 kb foreign genetic material and are favorable for transferring miRNA due to small size of miRNA. The genetic material is integrated into the DNA of the host cell by retroviruses so that only dividing cells are infected and stable expression of miRNA is achieved. Over the years, remarkable progress was made to understand DLBCL biology using advanced genomics and epigenomics technologies enabling oncologists to uncover multiple genetic mutations in DLBCL patients. These genetic mutations are involved in epigenetic modification, ability to escape immunosurveillance, impaired BCL6 and NF-κβ signaling pathways and blocking terminal differentiation. These pathways have since been identified and used as therapeutic targets for the treatment of DLBCL. Recently miRNAs were also identified to act either as oncogenes or tumor suppressors in DLBCL pathology by altering the expression levels of some of the known DLBCL related oncogenes. i.e., miR-155, miR-17-92 and miR-21 act as oncogenes by altering the expression levels of MYC, SHIP and FOXO1, respectively, conversely; miR-34a, mir-144 and miR-181a act as tumor suppressors by altering the expression levels of SIRT1, BCL6 and CARD11, respectively. Hundreds of miRNAs have already been identified as biomarkers in the prognosis and diagnosis of DLBCL because of their significant roles in DLBCL pathogenesis. In conclusion, miRNAs in addition to their role as biomarkers of prognosis and diagnosis could also serve as potential therapeutic targets for treating DLBCL.
