WebJun 27, 2006 · After UV irradiation, H2AX phosphorylation appears within 1 h in all phases of the cell cycle. Flow cytometry of γH2AX content after UV exposure shows that maximum G 1 γH2AX content is achieved after 2 h and is maintained out to 4 h (Fig. 2a). Between 4 and 8 h, G 1 γH2AX phosphorylation begins to recede and is completely absent by 24 h. WebCompositions and methods for treating cancer in a subject in need thereof is provided. In certain embodiments, the method includes administering therapy-induced senescent (TIS) cells and an immune checkpoint inhibitor to the subject. Also provided are compositions comprising therapy-induced senescent (TIS) cells.
