Abstract
Glioma represents a complex and heterogeneous disease, posing significant challenges to both clinicians and researchers. Despite notable advancements in glioma treatment, the overall survival rate for most glioma patients remains dishearteningly low. Hence, there is an urgent necessity to discover novel biomarkers and therapeutic targets specifically tailored for glioma. In recent years, long non-coding RNAs (lncRNAs) have emerged as pivotal regulators of gene expression and have garnered attention for their involvement in the development and progression of various cancers, including glioma. The dysregulation of lncRNAs plays a critical role in glioma pathogenesis and influences clinical outcomes. Consequently, there is growing interest in exploring the potential of lncRNAs as diagnostic and prognostic biomarkers, as well as therapeutic targets. By understanding the functions and dysregulation of lncRNAs in glioma, researchers aim to unlock new avenues for the development of innovative treatment strategies catered to glioma patients. The identification and thorough characterization of lncRNAs hold the promise of novel therapeutic approaches that could potentially improve patient outcomes and enhance the management of glioma, ultimately striving for better prospects and enhanced quality of life for those affected by this challenging disease. The primary objective of this paper is to comprehensively review the current state of knowledge regarding lncRNA biology and their intricate roles in glioma. It also delves into the potential of lncRNAs as valuable diagnostic and prognostic indicators and explores their feasibility as promising targets for therapeutic interventions.

Abstract
Glioma is among the most common primary brain tumors and one of the most aggressive and lethal forms of human cancer. Long noncoding RNAs (lncRNAs) have demonstrated great importance in the development and progression of cancer. The present study aimed to investigate the role of the novel tumor suppressive lncRNA on Chromosome 8p12 (TSLNC8), in cell proliferation, metastasis and apoptosis in human glioma. It was initially reported that the relative transcript levels of TSLNC8 were significantly decreased in human glioma tissues and cultured glioma cells, as evidenced by RT‑qPCR. Among clinical variables, the expression of TSLNC8 was negatively associated with tumor size, distant metastasis, and tumor, node and metastasis stage. MTT assay demonstrated that overexpression of TSLNC8 in glioma cell lines U25‑MG and SWO38 decreased, whereas knockdown of TSLNC8 in glioma cells SHG‑44 and BT325 increased the cell proliferative rate over 5 consecutive days. Additionally, cell metastasis was inhibited in U251 and SWO38 cells when cells were transfected with TSLNC8‑expressing plasmid as observed via Transwell and wound‑healing assays. Furthermore, cell apoptotic rate was upregulated in TSLNC8 plasmid‑treated U251 and SWO38 cells, and inhibited by siRNA against TSLNC8 in SHG‑44 and BT325 cells by cell apoptotic assay. The relative activities of caspase‑3 and caspase‑9 were increased by TSLNC8 overexpression and decreased by TSLNC depletion; however, the activity of caspase‑8 remained unchanged. The results of the present study demonstrated the inhibitory effects of TSLNC8 in human glioma, which may contribute to advancement in the diagnosis and treatment of patients with glioma in clinic.

A Potential Role for the Inhibition of PI3K Signaling in Glioblastoma Therapy. PLoS One 2015; 10:e0131670.

Abstract
Glioblastoma multiforme (GBM) is the most common primary brain tumor and among the most difficult to treat malignancies per se. In almost 90% of all GBM alterations in the PI3K/Akt/mTOR have been found, making this survival cascade a promising therapeutic target, particular for combination therapy that combines an apoptosis sensitizer, such as a pharmacological inhibitor of PI3K, with an apoptosis inducer, such as radio- or chemotherapy. However, while in vitro data focusing mainly on established cell lines has appeared rather promising, this has not translated well to a clinical setting. In this study, we analyze the effects of the dual kinase inhibitor PI-103, which blocks PI3K and mTOR activity, on three matched pairs of GBM stem cells/differentiated cells. While blocking PI3K-mediated signaling has a profound effect on cellular proliferation, in contrast to data presented on two GBM cell lines (A172 and U87) PI-103 actually counteracts the effect of chemotherapy. While we found no indications for a potential role of the PI3K signaling cascade in differentiation, we saw a clear and strong contribution to cellular motility and, by extension, invasion. While blocking PI3K-mediated signaling concurrently with application of chemotherapy does not appear to be a valid treatment option, pharmacological inhibitors, such as PI-103, nevertheless have an important place in future therapeutic approaches.

Knockdown of Rho-associated protein kinase 1 suppresses proliferation and invasion of glioma cells. Tumour Biol 2014; 36:421-8.

Abstract
Rho-associated protein kinase 1 (ROCK1), a serine/threonine protein kinase, affects cell invasion and migration by changing the status of the cytoskeleton. In recent years, ROCK1 was found to be overexpressed in a variety of tumors. However, the information of ROCK1 in glioma still remains elusive. In our study, the expression of ROCK1 in glioma tissues was examined by real-time PCR and the relationship between ROCK1 expression and clinical characteristics of patients with glioma was also analyzed. With the inhibition of ROCK1 expression by RNAi, the effects of ROCK1 on biological behaviors of glioma cells including cell viability, cell cycle, and cell invasion were probed in the U251 cell line by methyl thiazolyl tetrazolium (MTT) assay, flow cytometer analysis, and Transwell invasion experiment. In addition, the effects of ROCK1 on the regulation of Ki67, cyclin D1, matrix metalloproteinases 9 (MMP9), and E-cadherin were also investigated. The results indicated that ROCK1 messenger RNA (mRNA) was increased significantly compared to that in the adjacent normal tissue (P < 0.05) and the expression level of ROCK1 mRNA in high-grade malignant glioma tissue was significantly higher than that in low-grade malignant glioma tissue (P < 0.05). MTT assay and flow cytometer analysis revealed that the cell viability and cell proliferation in the ROCK1 small interfering RNA (siRNA) transfection group were markedly lower than those in the blank or negative control group (P < 0.05), and no obvious differences were found between the blank group and negative control group. The Transwell invasion experiments showed that the invasive ability of U251 cells in the ROCK1 siRNA transfection group was obviously lower than that in the blank or negative control group (P < 0.05), and there were no visible differences between the blank group and negative control group. Western blot demonstrated that the protein levels of Ki67, cyclin D1, and MMP9 in the ROCK1 siRNA transfection group were distinctly lower than those in the blank or negative control group (P < 0.05) and that the protein level of E-cadherin displayed an opposite variation (P < 0.05). In summary, the expressions of ROCK1 in glioma tissue were visibly upregulated and the increase of ROCK1 had a positive correlation with the malignant grade of glioma. The results implied that the proliferation and metastasis of the glioma cell could be inhibited by suppressing the expression of ROCK1, and our findings would provide a new target for intervention and treatment of glioma.
