In Vitro:

SB-218078 (2.5-5 μM; 18 hours; HeLa cells) treatment abrogates G2 cell cycle arrest caused by either γ-irradiation or a topoisomerase I Topotecan inhibition.

SB-218078 (500-625 μM; 96 hours; HeLa and HT-29 cells) treatment significantly increases the cytotoxicity of DNA damage.

 

In Vivo

SB-218078 (5 mg/kg; intraperitoneal injection; for 16 hours; C57/Bl6 mice) treatment could promote a strong increase of γ-H2AX and apoptosis throughout the lymphoma, while having no effect on a healthy spleen in Myc-induced lymphomas mouse model.
