Introduction: Glioma is the most common primary brain tumour in adults. Numerous studies have shown that neuregulins (NRGs) may be involved in the formation of glioma. Although NRG1 has been extensively studied in glioma, the functions of NRG2 in glioma development remain elusive.
Material And Methods: In the present study, we investigated the expression of NRG2 in different grades of human glioma samples, and analysed the functional effects of NRG2 in glioma cells mainly using wound healing assay and transmigration assay.
Results: We found that NRG2 was differentially expressed in different grades of human glioma/glioblastoma tissues. The data from wound healing assays demonstrated that NRG2 can differentially promote the migration of SHG44 human glioma, and U251 and U-87 MG human glioblastoma cells at different time points. The results of cell transmigration assays showed that, compared with the vehicle control, the number of cells that migrated to the underside of the insert was increased significantly for all the 3 cell lines treated with 5 nM of NRG2 for 12 hours.
Conclusions: In conclusion, our results demonstrated that NRG2 is expressed in gliomas to varying extents, and it may play roles in the migration of glioma cells in vitro. These data suggest that treatment targeting NRG2 signalling may partly reverse the migration-based metastasis of glioma cells.

Background: Bispecific T cell-engagers (BTEs) are engineered antibodies that redirect T cells to target antigen-expressing tumors. BTEs targeting various tumor-specific antigens, like interleukin 13 receptor alpha 2 (IL13RA2) and EGFRvIII, have been developed for glioblastoma (GBM). However, limited knowledge of BTE actions derived from studies conducted in immunocompromised animal models impedes progress in the field.

De-regulated protein expression contributes to tumor growth and progression in medulloblastoma (MB), the most common malignant brain tumor in children. MB is associated with impaired differentiation of specific neural progenitors, suggesting that the deregulation of proteins involved in neural physiology could contribute to the transformed phenotype in MB. Calsynthenin 1 (CLSTN1) is a neuronal protein involved in cell-cell interaction, vesicle trafficking, and synaptic signaling.

Targeting of diseased cells is one of the most urgently needed prerequisites for a next generation of potent pharmaceuticals. Different approaches pursued fail mainly due to a lack of specific surface markers. Developing an RNA-based methodology, we can now ensure precise cell targeting combined with selective expression of effector proteins for therapy, diagnostics or cell steering.

Glioblastoma (GBM) is the most common intracranial malignancy, but current treatment options are limited. Super-enhancers (SEs) have been found to drive the expression of key oncogenes in GBM. However, the role of SE-associated long non-coding RNAs (lncRNAs) in GBM remains poorly understood.
