Involvement of the microenvironment in the VC-Resist glioblastoma cells

In order to understand which molecular mechanisms are involved in radiation resistance and tumor propagation of glioblastoma, our laboratory has developed in-vitro models capable of mimicking the perivascular niche. Indeed, our laboratory hypothesizes that this niche is essential for glioblastoma cells to acquire a radioresistant character. That is why we are considering culturing our glioblastoma cells (GL261 cells) with the factors secreted by the perivascular niche (conditioned medium of mouse brain blood vessels) in order to study which phosphoproteins are activated in the presence of these factors. In parallel, a RNA sequencing analysis was carried out
