In a study conducted in 2019, Ma et al[44] demonstrated that exposure of glioblastoma cells to ionizing radiation (IR) induces phosphate and tensin homolog (PTEN) Y240 phosphorylation (pY240-PTEN), mediated by fibroblast growth factor receptor 2 (FGFR2). The gene discussed is PTEN; the disease is glioblastoma.
