1 Kinetics of histone H2AX phosphorylation and Chk2 activation in A549 cells treated with topotecan and mitoxantrone in relation to the cell cycle phase. Topotecan checkpoint kinase 2 Homo sapiens
2 In the present study we explored a relationship between H2AX phosphorylation and activation of checkpoint kinase 2 (Chk2) in human lung carcinoma A549 cells treated with TPT or with MXT. Topotecan checkpoint kinase 2 Homo sapiens
3 In the present study we explored a relationship between H2AX phosphorylation and activation of checkpoint kinase 2 (Chk2) in human lung carcinoma A549 cells treated with TPT or with MXT. Topotecan checkpoint kinase 2 Homo sapiens
4 Upon treatment with TPT or MTX, the activated Chk2 presented itself in form of either minute or large IF foci in the cell"s nucleoplasm. Topotecan checkpoint kinase 2 Homo sapiens
5 TPT or MXT induced Chk2 activation occurred at a distinctly slower pace, peaking at 4 h. While TPT-induced H2AX phosphorylation and Chk2 activation were maximal in S-phase cells, Chk2 activation was also much pronounced in G(2)M cells; the least affected by TPT were G(1) cells. Topotecan checkpoint kinase 2 Homo sapiens
6 TPT or MXT induced Chk2 activation occurred at a distinctly slower pace, peaking at 4 h. While TPT-induced H2AX phosphorylation and Chk2 activation were maximal in S-phase cells, Chk2 activation was also much pronounced in G(2)M cells; the least affected by TPT were G(1) cells.
