Histone H3.3K27M Represses p16 to Accelerate Gliomagenesis in a Murine Model of DIPG

This study shows that H3.3K27M mutation and PDGF signaling act in concert to accelerate gliomagenesis in a genetic mouse model and identifies repression of p16 tumor suppressor as a target of H3.3K27M, highlighting the G1–S cell-cycle transition as a promising therapeutic avenue.

Ursodeoxycholic acid (UDCA) is approved of cancer suppressive potential in several tumors. Here we researched on the antitumor potential of UDCA on GBM. The CCK-8 and colony formation was used for detecting cell viability. RNA sequencing hinted transcriptional profile and pathways. PCR and western blot tested the change of related markers. Phenotype changes as cell cycle,...

Introduction: The body of glioma-related literature has grown significantly over the past 25 years. Despite this growth in the amount of published research, gliomas remain one of the most intransigent cancers. The purpose of this study was to analyze the landscape of glioma-related research over the past 25 years using machine learning and text analysis.Methods: In April 2019, we downloaded glioma-related publications indexed in PubMed between 1994 and 2018. We used Python to extract the title, publication date, MeSH terms, and abstract from the metadata of each publication for bibliometric assessment. Latent Dirichlet all...

Authors: Xu R, Zhou F, Yu T, Xu G, Zhang J, Wang Y, Zhao L, Liu N Abstract MicroRNAs have been found ectopically expressed in many cancers and play essential roles in tumor EMT progress. Recent studies identified decreased miR-940 expression in glioma cells and may serve as a tumor-suppressor. However, whether miR-940 involve in glioma EMT remain poorly understood. Here we confirmed that miR-940 was significantly reduced in glioma cells and tissues. Introduction of miR-940 dramatically suppressed invasion and migration of glioma cells. Gain-of-function experiments showed ZEB2 as a direct target of miR-940, knockdow...

y Grochowski Metformin (MET), 1,1-dimethylbiguanide hydrochloride, is a biguanide drug used as the first-line medication in the treatment of type 2 diabetes. The recent years have brought many observations showing metformin in its new role. The drug, commonly used in the therapy of diabetes, may also find application in the therapy of a vast variety of tumors. Its effectiveness has been demonstrated in colon, breast, prostate, pancreatic cancer, leukemia, melanoma, lung and endometrial carcinoma, as well as in gliomas. This is especially important in light of the poor options offered to patients in the case of high-gra...

Immunotherapy directed at the PD-L1/PD-1 axis has produced treatment advances in various human cancers. Unfortunately, progress has not extended to glioblastoma (GBM), with phase III clinical trials assessing anti-PD-1 monotherapy failing to show efficacy in newly diagnosed and recurrent tumors. Myeloid-derived suppressor cells (MDSCs), a subset of immunosuppressive myeloid derived...

Casas-Tintó Pilar Sánchez-Gómez Despite the high frequency of EGFR and TP53 genetic alterations in gliomas, little is known about their crosstalk during tumor progression. Here, we described a mutually exclusive distribution between mutations in these two genes. We found that wild-type p53 gliomas are more aggressive than their mutant counterparts, probably because the former accumulate amplifications and/or mutations in EGFR and show a stronger activation of this receptor. In addition, we identified a series of genes associated with vesicular trafficking of EGFR in p53 wild-type gliomas. Among t...
