Myricetin enhances radiosensitivity on inhibiting the tumor cell proliferation. (A) Radiosensitivity was measured by CCK-8 assay in the human lung cancer cell line A549 treated with 25 μM of myricetin alone or myricetin plus radiotherapy (1 h before IR and maintained for 24 h), Compared to the radiotherapy alone group, the proliferation of A549 cells were slower down significantly in radiotherapy combine with myricetin group. (B) Radiosensitivity of the human lung cancer cell line H1299, which results was same as the A549.
