Focused ultrasound combined with miR-1208-equipped exosomes inhibits malignant progression of glioma.

Background: Exosomes (Exos) can safely and effectively deliver therapeutic substances to glioma cells; however, their blood-brain barrier (BBB) crossing capacity remains limited. Focused ultrasound (FUS) can transiently, reversibly, and locally open the BBB, while the effects of FUS combined with Exos-miRNA on the treatment of glioma have not been explored to date.

Methods: Exos were extracted by differential centrifugation and the efficacy of miR-1208-loaded Exos combined with FUS in the treatment of glioma was detected by CCK-8, colony formation, flow cytometry, transwell and tumour xenografts assays.

Dual role of pseudogene TMEM198B in promoting lipid metabolism and immune escape of glioma cells.

Dysregulation of pseudogenes, enhancement of fatty acid synthesis and formation of immunosuppressive microenvironment are important factors that promote the malignant progression of glioma. It is of great significance to search for the molecular mechanism of interaction between the three and then perform targeted interference for improving the treatment of glioma. In this study, we found that pseudogene transmembrane protein 198B (TMEM198B) was highly expressed in glioma tissues and cell lines, and it could promote malignant progression of glioma by regulating lipid metabolism reprogramming and remodeling immune microenvironment.

LOXL1-AS1 communicating with TIAR modulates vasculogenic mimicry in glioma via regulation of the miR-374b-5p/MMP14 axis.

At present, growing evidence indicates that long non-coding RNAs (lncRNAs) participate in the progression of glioma. The function of LOXL1-AS1 in vasculogenic mimicry (VM) in glioma remains unclear. First, the expressions of TIAR, the lncRNA LOXL1-AS1, miR-374b-5p and MMP14 were examined by qRT-PCR and Western blot in both, glioma tissues and glioma cell lines.

HOXC6/8/10/13 predict poor prognosis and associate with immune infiltrations in glioblastoma.

Background: Glioblastoma (GBM), characterized by deregulated cell proliferation and immune cells infiltration, is a common and lethal tumor of the central nervous system. Recently, the infiltration of immune cells has attracted attention as a potential novel GBM immunotherapy option. Homeobox C cluster (HOXC) is an evolutionarily conserved family of transcriptional factors that are involved in embryogenesis and tumorigenesis.

Comprehensive Analysis of CD163 as a Prognostic Biomarker and Associated with Immune Infiltration in Glioblastoma Multiforme.

Background: Glioblastoma multiforme (GBM) is the most common and aggressive primary malignancy in adults with high aggression. The prognosis of GBM patients is poor. There is a critical need for novel biomarkers for the prognosis and therapy of GBM.

SUMOylation of IGF2BP2 promotes vasculogenic mimicry of glioma via regulating OIP5-AS1/miR-495-3p axis.

Glioma is the most common primary malignant tumor of human central nervous system, and its rich vascular characteristics make anti-angiogenic therapy become a therapeutic hotspot. However, the existence of glioma VM makes the anti-angiogenic therapy ineffective. SUMOylation is a post-translational modification that affects cell tumorigenicity by regulating the expression and activity of substrate proteins.

Linc00475 promotes the progression of glioma by regulating the miR-141-3p/YAP1 axis.

Glioma is the most prevalent and lethal primary brain tumour. Abundant long non-coding RNAs ( lncRNAs) are aberrant and play crucial roles in the oncogenesis of glioma. The exact functions of linc00475 in glioma remain blurred.
