The results showed that the cell viability was not changed or promoted by 2 Gy irradiation whereas significantly suppressed by 8 Gy radiation; the cell viability was significantly suppressed by NKILA overexpression whereas promoted by NKILA knockdown; the cellular effect of 2 Gy or 8 Gy radiation on laryngeal cancer cell viability could be partially reversed by NKILA overexpression or NKILA knockdown, respectively (Fig. 4A and B). This evidence concerns the gene NKILA and laryngeal carcinoma.
