miR-152 and lncRNA H19 have been frequently implicated in various cellular processes including cell proliferation, invasion, angiogenesis, apoptosis. However, the interaction between glioma has never reported. RT-qPCR was used to examine expression of human lines normal astrocytes (NHAs). The assessed by dual-luciferase reporter assay. MTT assay Transwell invasion were determine proliferation U251 U87 cells. A xenograft tumor experiment performed confirm role vivo. results showed that...

N6-methyladenosine (m6A) RNA methylation, the most common form of mRNA modification and regulated by m6A methylation regulators ("writers," "erasers," "readers"), has been reported to be associated with progression malignant tumor. However, its role in glioblastoma (GBM) poorly known. This study aimed identify expression, potential functions, prognostic values GBM. Here, we revealed that 13 central were firmly related clinical molecular phenotype Taking advantage consensus cluster analysis,...

The progression of most human cancers mainly involves the gradual accumulation loss differentiated phenotypes and sequential acquisition progenitor stem cell-like features. Glioblastoma multiforme (GBM) cells (GSCs), characterized by self-renewal therapeutic resistance, play vital roles in GBM. However, a comprehensive understanding GBM stemness remains elusive. Two indices, mRNAsi EREG-mRNAsi, were employed to comprehensively analyze stemness. We observed that was significantly related...

Background/Aims: Thyroid carcinoma (TC) is a highly lethal malignant cancer and its carcinogenesis remains undetermined. Dysregulation of microRNAs (miRNAs) well known to be involved in the development various cancers, including TC, whereas role miR-3666 pathogenesis TC has not been appreciated. Methods: We analyzed levels MET tissue relationship with patients' prognosis. then overexpressed by miRNA mimics transfection inhibited antisense cells. Cell survival growth were CCK-8 assay MTT...

Temozolomide (TMZ) was used for clinical postoperative or non-surgical chemotherapy patients. However, its effect remains unsatisfactory and gradually discovered that the presence of chemoresistance. To explore more effective therapy using TMZ, we investigate effects combination application TMZ together with Sonodynamic (SDT), which is based on ultrasonic activation a sonosensitizer, low toxicity, noninvasive, deeper penetrability promising approach treating malignant glioma by inducing...

To better understand the Ca2+ overload mechanism of SDT killing gliomas, we examined hypothesis that early application mechanosensitive channel Piezo1 antagonist (GsMTx4) could have a anti-tumor effect.The in vitro effect low-energy combined with GsMTx4 or agonist Yoda 1 on both ROS-induced distribution as well opening and dissociation polymerization lipid complex were assessed. The same groups also studied to determine their effects tumor-bearing BALB/c-nude C57BL/6 intracranial tumors,...

Long noncoding RNAs have key roles in glioma progression. However, the function and mechanisms of action long RNA, LINC00346, remain unclear. In our study, we observed that LINC00346 levels were increased tissue samples, according to Gene Expression Profiling Interactive Analysis, its related disease-free survival overall rates, suggesting a high level expression corresponds poor prognosis. We next confirmed tissues cell lines showed knockdown suppressed proliferation, migration invasion;...

<title>Abstract</title> Background As the strong adaptive radio-chemoresistance, GBM represents worst prognosis form of primary malignant tumor within central nervous system. Previous researches indistinctly focused on mechanisms resistance to X-ray or chemo regimen in isolation, however, it is still unknown if there exists synergistic interact effect between above two kinds resistances. Methods We established TMZ-resistant cell lines (TMZ-R) by chronically exposing U87MG TMZ, and DMSO was...

Abstract Background: The radical cure of Glioblastoma multiforme (GBM) is a troublesome medical problem, owing to its resistance temozolomide chemotherapy and very poor surgical results or high relapse rate. Resistance emerges from numerous signalling pathways that are altered in GBM, especially the hedgehog pathway. Hence, further research urgent needed identify more effective treatment modalities. Methods: We evaluated effect ATO on viability, cell proliferation, colony formation...
