Identification of novel therapeutics in glioblastoma remains crucial due to the devastating and infiltrative capacity of this malignancy. The current study was aimed to appraise effect of arsenic trioxide (ATO) in U87MG cells. The results demonstrated that ATO induced apoptosis and impeded proliferation of U87MG cells in a dose-dependent manner and also inhibited classical NF-${\kappa}B$ signaling pathway. ATO further upregulated expression of Bax as an important proapoptotic target of NF-${\kappa}B$ and also inhibited mRNA expression of survivin, c-Myc and hTERT and suppressed telomerase activity. Moreover, ATO significantly increased adhesion of U87MG cells and also diminished transcription of NF-${\kappa}B$ down-stream targets involved in cell migration and invasion, including cathepsin B, uPA, MMP-2, MMP-9 and MMP-14 and suppressed proteolytic activity of cathepsin B, MMP-2 and MMP-9, demonstrating a possible mechanism of ATO effect on a well-known signaling in glioblastoma dissemination. Taken together, here we suggest that ATO inhibits survival and invasion of U87MG cells possibly through NF-${\kappa}B$-mediated inhibition of survivin and telomerase activity and NF-${\kappa}B$-dependent suppression of cathepsin B, MMP-2 and MMP-9.

Given the systemic immunogenic effects of Bacillus Calmette-Guérin (BCG) therapy in patients with bladder cancer and its non-specific immunogenic effects in viral respiratory diseases, we aimed to study severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in bladder cancer patients with a history of BCG therapy. In the present study, all bladder cancer survivors with a history of BCG therapy were identified and included in the study according to the data recovered from the UORC (Uro-Oncology Research Center) registry database. These patients were followed up in terms of acquiring coronavirus disease 2019 (COVID-19). Among the studied patients, 102 eligible bladder cancer patients with a history of BCG therapy entered the study. The males constituted the majority of the patients (86.3%), and more than half of the study population (55.9%) were above 65 years old. Among the understudy patients, 12.7% were confirmed for COVID-19. The study results did not show a statistically significant association between the time and number of BCG therapy courses and SARS-CoV-2 infection. Although no statistically significant association was observed between receiving BCG therapy and developing COVID-19, the infection rate in patients who had recently received BCG therapy was lower than those who had received therapy more than a year ago.
