PKMYT1 and neoplasm: In both cell lines, following treatment with silencing of PKMYT1 + radiation (4Gy of X-rays), the cells also accumulated in G2/M, but to a much lower level compared to the radiation control (p < 0.05), suggesting that the silencing of PKMYT1 can eliminate the radiation-induced G2/M arrest, thereby improving the radiosensitivity of tumor cells.
