Long non-coding RNA PVT1 regulates glioma proliferation, invasion, and aerobic glycolysis via miR-140-5p.

CONCLUSIONS: PVT1 promotes proliferation, invasion, and aerobic glycolysis in glioma cells by regulating miR-140-5p. PMID: 31957841 [PubMed - in process]

The research community has long used progeroid syndromes such as Hutchinson-Gilford progeria syndrome and Werner syndrome as tools in the investigation of aging. This category of conditions are colloquially thought of as accelerated aging, but are in fact only a little similar to aging. The various underling genetic causes of progeria result in accelerated accumulation of cellular damage of various sorts, different in each case, leading to tissue dysfunction and outcomes that resemble a range of normal age-related conditions. Aging is itself a process of damage accumulation, so it isn't surprising to find some degree of si...

(Johns Hopkins Medicine) In experiments with human cells and mice, researchers at the Johns Hopkins Kimmel Cancer Center report evidence that combining the experimental cancer medication TAK228 (also called sapanisertib) with an existing anti-cancer drug called trametinib may be more effective than either drug alone in decreasing the growth of pediatric low-grade gliomas.

ConclusionA radiomic model derived from multi-parameter MRI of the gliomas was successful in the risk stratification of diffuse glioma patients. These data suggested that radiomics provided an alternative approach for survival estimation and may improve clinical decision-making.

In this study, we chose Cytokeratin-pan, GFAP, and LCA as three immunohistochemical indicators. Intraoperative IHC was done by Novodiax ihcDirect technology combined with Leica Bond auto-staining. Compared with the manual method recommended for the reagents (Novodiax ihcDirect), the results show that auto-staining has better stability and high reproducibility in coloration, which has broad prospects for future application.

This study intends to investigate the mechanisms of ubiqutin-specific protease 22 (USP22)/B cell-specific Moloney murine leukemia virus integration site 1 (BMI1) on the biological phenotypes of glioma stem cells (GSCs) under hypoxia.Main methodsWestern blot, Cell Counting Kit-8, colony formation and flow cytometry assays were preformed to evaluate cells biological behaviors. Luciferase assay was utilized to identify the associations among USP22, HIF-1α and BMI1.Key findingsSilencing USP22 reduced the stemness and proliferation of GSCs, and increased its apoptosis in response to hypoxia. Whilst, overexpression of BMI1...

This study investigated the function and mechanism of PVT1 knockdown in the proliferation and malignant transformation of human gliomas. We firstly examined the expression levels of PVT1 and miR-424 in human glioma tissues and cell lines. We also used gene manipulation techniques to explore the effects of PVT1 knockdown on cell viability, migration, invasion, and miR-424. We found that PVT1 knockdown effectively inhibited cell viability, migration and invasion of human glioma cells and increased miR-424 expression. Based on the negative correlation between PVT1 and miR-424, we then confirmed the direct interaction between ...

This study aimed to assess the relationship between plasmacytoma variant translocation 1 (PVT1) and enhancer of zeste homolog 2 (EZH2), and their effects on the proliferation and invasion of glioma cells. The expression levels of PVT1 and EZH2 in human glioma tissues and cell lines were measured using qRT-PCR. Then, after siRNA-PVT1 and entire PVT1 sequence vector transfection, we determined the regulation roles of PVT1 on the proliferation, apoptosis, migration and invasion of glioma cells.   We found that the expression levels of both PVT1 and EZH2 were up-regulated in human glioma tissues and cell li...
