However, in comparison to sham-irradiated controls, 3 Gy or 15 Gy X-ray irradiation led to a significant increase in GFAP mRNA expression in assembloids or co-cultures of organoid slices with GFP+/c-MYChigh tumor-like cells, respectively, when compared to the corresponding sham-irradiated controls (Figure 9A). This evidence concerns the gene GFAP and neoplasm.
