AIM2 expression is associated with cellular irradiation resistance and migration ability in OSCC cells. A–I RT-PCR for the endogenous mRNA levels of AIM2 and GAPDH, crystal violet staining (upper)/histogram (lower) for colony formation post-treatment without or with irradiation at 4 Gy and Giemsa staining (upper)/histogram (lower) for the migrated cells in the tested OSCC cell lines (A–C), HSC4 cell variants (D–F) and SAS cell variants (G–I). in A, D and G, GAPDH was used as an internal control of the experiment. The abbreviations of PT, NS, VC and OE are parental, non-silencing, vector control and overexpression, respectively. ***p < 0.001
