Effects of Reduced Graphene Oxides on Apoptosis and Cell Cycle of Glioblastoma Multiforme. Int J Mol Sci 2018; 19:ijms19123939.

Abstract
Graphene (GN) and its derivatives (rGOs) show anticancer properties in glioblastoma multiforme (GBM) cells in vitro and in tumors in vivo. We compared the anti-tumor effects of rGOs with different oxygen contents with those of GN, and determined the characteristics of rGOs useful in anti-glioblastoma therapy using the U87 glioblastoma line. GN/ExF, rGO/Term, rGO/ATS, and rGO/TUD were structurally analysed via transmission electron microscopy, Raman spectroscopy, FTIR, and AFM. Zeta potential, oxygen content, and electrical resistance were determined. We analyzed the viability, metabolic activity, apoptosis, mitochondrial membrane potential, and cell cycle. Caspase- and mitochondrial-dependent apoptotic pathways were investigated by analyzing gene expression. rGO/TUD induced the greatest decrease in the metabolic activity of U87 cells. rGO/Term induced the highest level of apoptosis compared with that induced by GN/ExF. rGO/ATS induced a greater decrease in mitochondrial membrane potential than GN/ExF. No significant changes were observed in the cytometric study of the cell cycle. The effectiveness of these graphene derivatives was related to the presence of oxygen-containing functional groups and electron clouds. Their cytotoxicity mechanism may involve electron clouds, which are smaller in rGOs, decreasing their cytotoxic effect. Overall, cytotoxic activity involved depolarization of the mitochondrial membrane potential and the induction of apoptosis in U87 glioblastoma cells.

Abstract
Hyperbaric oxygen (HBO) therapy is widely used as an adjunctive treatment for various pathological states, predominantly related to hypoxic and/or ischaemic conditions. It also holds promise as an approach to overcoming the problem of oxygen deficiency in the poorly oxygenated regions of the neoplastic tissue. Occurrence of local hypoxia within the central areas of solid tumours is one of the major issues contributing to ineffective medical treatment. However, in anti-cancer therapy, HBO alone gives a limited curative effect and is typically not applied by itself. More often, HBO is used as an adjuvant treatment along with other therapeutic modalities, such as radio- and chemotherapy. This review outlines the existing data regarding the medical use of HBO in cancer treatment, with a particular focus on the use of HBO in the treatment of brain tumours. We conclude that the administration of HBO can provide many clinical benefits in the treatment of tumours, including management of highly malignant gliomas. Applied immediately before irradiation, it is safe and well tolerated by patients, causing rare and limited side effects. The results obtained with a combination of HBO/radiotherapy protocol proved to be especially favourable compared to radiation treatment alone. HBO can also increase the cytostatic effect of certain drugs, which may render standard chemotherapy more effective. The currently available data support the legitimacy of conducting further research on the use of HBO in the treatment of malignancies.

Abstract
Cancer patients often require antidepressant treatment due to comorbid depressive disorder. However, recent studies have demonstrated that antidepressant drugs affect the efficacy of chemotherapy and promote progression of cancer. Apart from the main mood-improving effect, antidepressant drugs also produce analgesic, anxiolytic, hypnotic and pro-cognitive actions. Patients suffering from brain cancer constitute the greatest percentage of depressive cancer patients. However, vital safety and efficacy issues related to combined therapy with temozolomide, the first-line cytostatic in patients diagnosed with glioblastoma multiforme, and antidepressant drugs have yet to be addressed. The aim of the present studies was to evaluate the effect of three antidepressant drugs (imipramine, fluoxetine and tranylcypromine) on the cytotoxic efficacy of temozolomide on T98G cells, a human glioblastoma cell line. In our experiments, we used a complex experimental in vitro system to mimic the instability of a tumour's oxygen supply, thereby reproducing conditions that occur inside the tumour. The effect of the interaction between temozolomide and antidepressant drugs on viability, apoptosis and intensity of divisions of glioblastoma cells was evaluated under different oxygen conditions. The results of our studies demonstrated that imipramine and tranylcypromine reduced the cytotoxic efficacy of temozolomide under some oxygen conditions while fluoxetine did not demonstrate such effects.

Knockdown of the AKT3 (PKBγ), PI3KCA, and VEGFR2 genes by RNA interference suppresses glioblastoma multiforme T98G cells invasiveness in vitro. Tumour Biol 2014; 36:3263-77.

Abstract
Glioblastoma multiforme (GBM) is the most common primary brain malignancy, having a very poor prognosis and is characterized by extensive brain invasion as well as resistance to the therapy. The phosphoinositide 3-kinase (PI3K)/Akt/PTEN signaling pathway is deregulated in GBM. Besides, florid vascularization and aberrantly elevated vascular endothelial growth factor (VEGF) occur very often. The present study was designed to examine the inhibitory effect of AKT3, PI3KCA, and VEGFR2 small interfering RNAs (siRNAs) on GBM cell invasiveness. T98G cells were transfected with AKT3, PI3KCA, and/or VEGFR2 siRNAs. VEGFR2 protein-positive cells were identified by flow cytometry using specific monoclonal anti-VEGFR2 antibodies. Alterations in messenger RNA (mRNA) expression of VEGF, VEGFR2, matrix metalloproteinases (MMPs) (MMP-2, MMP-9, MMP-13, MMP-14), tissue inhibitors of metalloproteinases (TIMPs) (TIMP-1, TIMP-3), c-Fos, c-Jun, hypoxia-inducible factor-1α (HIF-1α), ObRa, and cathepsin D genes were analyzed by qRT-PCR. Cells treated with specific siRNA were also analyzed for invasion using the Matrigel invasion assay. We have found significantly lower mRNA levels of MMPs, cathepsin D, VEGF, VEGFR2, HIF-1α, and c-Fos/c-Jun ratio, as well as significantly higher mRNA level of TIMPs in AKT3 and PI3KCA siRNA transfected cells compared to untransfected cells, while significantly lower mRNA levels of MMPs (MMP-2, MMP-9, MMP-14) and TIMP-1, as well as significantly higher mRNA level of TIMP-3, were shown only in cells transfected with VEGFR2 siRNA. The positive correlation between MMP-13 and ObRa mRNA copy number has been found. Summarizing, transfection of T98G cells with AKT3, PI3KCA, or VEGFR2 siRNAs leads to a significant reduction in cell invasiveness. The siRNA-induced AKT3, PI3KCA, and VEGFR2 mRNA knockdown may offer a novel therapeutic strategy to reduce the invasiveness of GBM cells.

Abstract
Introduction: Malignant cancers of the central nervous system with the consequences of strong symptoms and urgent progression of the disease put the palliative teams of the palliative wards in the feeling of helplessness. Difficulties in undertaking the treatment and lack of experience with such patients cause their higher mortality rate. The main aim of the case: The aim of the study is to present the clinical treatment and the palliative care of the patient with Astrocytoma GII/GIII (ICD 10 C -71). Data and Methods: Analyses of the medical documentation, observation and nursing interview with the patient’s family were taken into account.Case study: A 39 year old woman, who had never been cured for cancer before, was transferred from the neurosurgery to the palliative care ward with brain cancer astrocytoma GII/GIII without any contact and lack of improvement of her condition. After a symptomatic treatment, a combined therapy was applied which consisted of oral chemotherapy (Lomustine) and radiotherapy. The patient’s condition was systematically improving. The patient and her family received care and support from the therapeutic team, which made it possible for the patient to return back home after eight months on the ward. It made the patient function alone and lead active social life despite of the limitations caused by cancer.Conclusions: It is not advisable to make quick decisions of ceasing the treatment only because of the diagnosis of inoperable brain malignant cancers. The therapeutic team play a significant role in the process of restoring the vital functions of the patient and in the entire therapy. Especially the family, who are the active members of the team, become very important. Education and the family support is essential and helps to tackle such a difficult chronic disease with bad prognosis. It also helps to understand specific symptoms and behaviours of the patients with brain cancer much better. Furthermore, it helps to lower the level of the family’s anxiety and frustration. Active cooperation of the family and the therapeutic team allows the patient to get back home AFVSS.
