Background: Zika virus (ZIKV) has recently become a major matter of concern since its association with microcephaly cases in newborns was determined. From then on, ZIKV has been untiringly studied, and several scientific data have shown the virus' tropism to neural cells. Previous studies have proposed that ZIKV induced glioblastoma cells death, suggesting that ZIKV and ZIKV-associated molecules might induce intracellular biochemical alterations, and thereby be alternatives for neural cancer management. In this sense, the present contribution presents a prospective approach for glioblastomas management: producing a ZIKV-based therapy that stimulates glioblastoma control. We developed an attenuated ZIKV prototype based on bacterial outer membrane vesicles (OMV). The attenuated ZIKV was applied on glioblastoma cells, where cytopathic and cytostatic effects were evaluated. Glioblastoma cells, with and without treatment, were submitted to mass spectrometry analysis. Results: Microscopic analysis showed cytopathic effects induced by ZIKV prototype on glioblastoma cells after 24 and 48 h post-treatment. DNA fragmentation assay and TNF-alpha expression were indicative that ZVp induced cell damage and death. The metabolomics investigation elected 5 different biomarkers that might be associated with cell cytopathic effects, highlighting intracellular biochemical modifications induced by the attenuated ZIKV. The remarkable evidence of cell death in glioblastoma stimulated further studies that rendered a preliminary screening with other tumor cell lineages, though anti-proliferative activity test. Among the 11 tumors evaluated, prostate and ovarian tumors were the most affected by ZIKV prototype, and other 6 cell lines also presented cytostatic effects. Conclusions: Results ultimately demonstrated that this prototype not only emerges as a potential alternative for glioblastoma management, but may also be an important tool against other important tumors.
