NMDA Receptor-Mediated Signaling Pathways Enhance Radiation Resistance, Survival and Migration in Glioblastoma Cells-A Potential Target for Adjuvant Radiotherapy.

Glioblastoma is one of the most aggressive malignant brain tumors, with a survival time less than 15 months and characterized by a high radioresistance and the property of infiltrating the brain. Recent data indicate that the malignancy of glioblastomas depends on glutamatergic signaling via ionotropic glutamate receptors. In this study we revealed functional expression of Ca-permeable NMDARs in three glioblastoma cell lines.

1-year outcome after treatment of uterovaginal prolapse with a 6-point fixation mesh.

Introduction: The aim of this study was to describe the safety and anatomical results of a surgical approach with a single-incision 6-point fixation vaginal mesh for the treatment of pelvic organ prolapse at perioperatively and at 1-year follow-up.

Materials And Methods: This was a prospective observational study of patients who underwent operation receiving an InGYNious anterior transvaginal mesh. All patients with symptomatic stage II prolapse or higher were included in the study.

NMDA Receptor Signaling Mediates cFos Expression via Top2β-Induced DSBs in Glioblastoma Cells.

The activation of Ca-permeable -methyl-D-aspartic acid (NMDA) receptor channels (NMDARs) is crucial for the development and survival of neurons, but many cancers use NMDAR-mediated signaling as well, enhancing the growth and invasiveness of tumors. Thus, NMDAR-dependent pathways emerge as a promising target in cancer therapy. Here, we use the LN229 and U-87MG glioblastoma multiforme (GBM) cells and immunofluorescence staining of 53BP1 to analyze NMDAR-induced DNA double-strand breaks (DSBs), which represent an important step in the NMDAR signaling pathway in neurons by facilitating the expression of early response genes.
