Migration-inducing gene-7 (Mig-7) is closely related to tumor invasion and metastasis. However, the detailed molecular mechanism of Mig-7-mediated promotion of glioma cell invasion requires further investigation. Therefore, this study aimed to investigate the molecular mechanism by which Mig-7 promotes invasion and growth of glioma tumor cells. After collecting 65 glioma tissues and 16 non-tumor tissues, the expression difference of Mig-7 between tumor tissues and non-tumor tissues was analyzed. The molecular mechanism of Mig-7 in tumor cells was investigated by knockdown or overexpression of Mig-7 in U87MG cells. Specifically, the expression levels of mitogen-activated protein kinase (MAPK) signaling pathway-related molecules were detected in cells that knocked down Mig-7. MTT, Transwell, and three-dimensional cell culture assays were used to detect the survival, migration, invasion, and tube formation of U87MG cells that overexpressed Mig-7 were treated with the MAPK signaling pathway inhibitors (SP600125, SCH772984, and SB202190). The effect of Mig-7 on the tumorigenic ability of U87MG cells was investigated by subcutaneous tumorigenic experiment in nude mice. The corresponding results indicated that Mig-7 expression was significantly higher in glioma tissues and cell lines compared to that in non-neoplastic brain tissues and normal glial cell lines. In U87MG cells, downregulation or overexpression of Mig-7 inhibited or promoted the expression of MMP-2, MMP-9, LAMC2, EphA2, and VE-cadherin, and phosphorylation levels of ERK1/2, JNK, and p38. Mig-7 overexpression promoted migration, invasion, cell viability, and tube formation, which were reversed by the MAPK signaling pathway inhibitors. Mig-7 overexpression promoted subcutaneous tumor growth in mice and upregulated the phosphorylation levels of ERK1/2, JNK, and p38 and the expression of Ki-67. These effects of Mig-7 overexpression were reversed by MAPK pathway inhibitors. Overall, these results suggest that Mig-7 may be a novel biomarker and potential therapeutic target for glioma, with the MAPK pathway playing a key role in the corresponding Mig-7 mechanism of action.</p>","PeriodicalId":19266,"journal":{"name":"Neoplasma","volume":"70 4","pages":"534-544"},"PeriodicalIF":3.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41167489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory models for functional testing which mimic the spread of metastatic cells are needed for efficient investigation of the underlying mechanisms and therapeutic intervention. Here, we describe novel isogenic variants LMC3 and CTC3 of human TNBC cell line MDA-MB-231 that were derived by repeated injection of tumor cells into the tail vein of immunodeficient mice and subsequent selection of metastatic cells from lung metastases. These variants have increased migration potential, altered expression profiles, and elevated tumorigenic potential. Moreover, cell line CTC3 readily produces metastases in the lungs and bone marrow and detectable viable circulating tumor cells in the blood.

R. coriaria and C. zeylanicum bark were used as the chemopreventive-therapeutic agents taken by rats in the powder form in the diet at two different concentrations during the entire period of two experiments carried out separately: lower concentration 1 g/kg - 0.1% and higher concentration 10 g/kg - 1%. The serum levels of cytokines of IL-6, IL-10, and TNF-α were determined using an enzyme-linked immunosorbent assay. In the first experiment treated with R. coriaria, a significant decrease in serum levels of IL-6 and TNF-α was present at higher concentrations compared to the chemoprevention-free control group. R. coriaria at lower concentrations non-significantly reduced the serum levels of IL-6 and TNF-α when compared to controls. A significant decrease in serum levels of TNF-α was present at higher concentrations compared to lower concentrations. The significant effect of R. coriaria on the serum levels of IL-10 was not observed. In the second experiment treated with C. zeylanicum bark, a significant decrease in serum levels of IL-6 was observed in lower and higher concentrations compared to the chemoprevention-free control group.

It is reported that lncRNA plasmacytoma variant translocation 1 (PVT1) is involved in colorectal cancer (CRC), however, the underlying mechanism remains to be explored deeply, especially by in vivo models. In the present study, bioinformatics analysis showed that the expression level of PVT1 was upregulated in CRC tissues and highly associated with poor prognosis of CRC patients. In cultured CRC cells, knockdown of PVT1 inhibited cell proliferation and migration of CRC cells, while overexpression of PVT1 promoted the progression of CRC cells. In zebrafish xenografts, the silencing of PVT1 also suppressed the growth and metastasis of CRC cells. For mechanism studies, the binding relationships among PVT1, miR-24-3p, and Neuropilin 1 (NRP1) were predicted by starBase firstly. The luciferase reporter assays verified that PVT1 and NRP1 could bind with miR-24-3p directly. Further studies showed miR-24-3p negatively regulated the progression of CRC cells, the inhibition of miR-24-3p counteracted the repression effects of CRC progression when knocking down PVT1. In addition, the expression of NRP1 was regulated by PVT1, and NRP1 overexpression could partially rescue the inhibition effects of CRC progression when knocking down PVT1 in vitro and in vivo.

We found that application of Pliaglis to melanoma significantly reduced its growth and this effect was even pronounced in mice treated with the anti-PD-1 antibody. To determine the mechanisms and pathways responsible for the observed effect, the in vitro effect of incubating melanoma cells with lidocaine and/or tetracaine and the in vivo gene expression of cancer and immune-related factors, percentage of immune cells, gene expression of selected neurotransmitter receptors and nerve growth factors in melanoma tissue were studied.
