KCNN4 and neoplasm: This is also evident from the radiation-mediated delay in tumor volume increase, which was larger for KCa3.1 KO than for WT tumors (Figure 5G.)In addition, such in vivo radioprotective function of KCa3.1 can be deduced from the observation that mice with irradiated KCa3.1 KO tumors showed the highest scatter towards longer survival times with one complete therapy responder (Figure 5E).
