Special Issue Information

Dear Colleagues,

The success in glioma treatment to date has been very modest, and these tumors remain incurable. Inter- and intratumoral heterogeneity are essential features of glioma. Additionally, glioma cancer stem cells supply additional variability to the cell populations. To apply a targeted therapy to aggressive clones of the tumor, the fates of these clones have to be followed, for example, by studying the possibility of eradicating them.

The application of theranostics to treat glioma requires developing at least two arms of research. The first arm includes the discovery and verification of more diagnostics and prognostics of molecular biomarkers, including circulating biomarkers in liquid biopsies, in addition to conventional ones. The second includes the development of elements which are able to recognize these markers, both molecular recognition elements (MoREs) and cellular recognition elements (CeREs, like CAR T cells). Different theranostic MoREs include monoclonal antibodies, therapeutic peptides, protein scaffolds, aptamers, crypto-aptamers (such as G-qudruplexes), and pseudo-aptamers. Further, MoREs could be supplied with additional active molecular modules, both in ensembles and as conjugates; they could also be a part of supramolecular nanoconstructs. Application of different therapeutic nucleic acids and their complexes, including editing complexes and viruses, is an attractive supplement. Combinations of theranostics with conventional chemo- and radiotherapies will also be considered.

The Special Issue aims to gather ongoing research on molecular aspects of glioma, including growth factor receptor signal transduction involved in malignant cell survival, proliferation, and invasion, as well as inter- and intratumoral heterogeneity. It will focus on the discovery and verification of molecular markers essential for exploring new targets and development of novel personalized theranostic approaches.

The goal is to gather the data collected by researchers and clinicians to provide a systemic view on glioma. We welcome articles in glioma, including topics on neuropathology/genetics, models of glioma, and investigational therapies.

Glioblastoma multiforme (GBM) is a malignant primary brain tumor. The 5-year relative survival rate of patients with GBM remains <30% on average despite aggressive treatments, and secondary therapy fails in 90% of patients. In chemotherapeutic failure, detoxification proteins are crucial to the activity of chemotherapy drugs. Usually, glutathione S-transferase (GST) superfamily members act as detoxification enzymes by activating xenobiotic metabolites through conjugation with glutathione in healthy cells. However, some overexpressed GSTs not only increase GST activity but also trigger chemotherapy resistance and tumorigenesis-related signaling transductions. Whether GSTM3 is involved in GBM chemoresistance remains unclear. In the current study, we found that T98G, a GBM cell line with pre-existing temozolomide (TMZ) resistance, has high glycolysis and GSTM3 expression. GSTM3 knockdown in T98G decreased glycolysis ability through lactate dehydrogenase A activity reduction. Moreover, it increased TMZ toxicity and decreased invasion ability. Furthermore, we provide next-generation sequencing–based identification of significantly changed messenger RNAs of T98G cells with GSTM3 knockdown for further research. GSTM3 was downregulated in intrinsic TMZ-resistant T98G with a change in the expression levels of some essential glycolysis-related genes. Thus, GSTM3 was associated with glycolysis in chemotherapeutic resistance in T98G cells. Our findings provide new insight into the GSTM3 mechanism in recurring GBM. Full article
