Fig. 4. Effects of PLDR on PC-3 and PANC-1 subcutaneous transplanted tumors. Tumor growth curves (a, d), survival curves (b, e), and body weight change curves (e, f) of mice bearing PC-3-xenograft tumors (a‒c) and PANC-1-xenograft tumors (d‒f) were generated. Values are presented as mean±SD (n=5). ^* P<0.05, ^** P<0.01. RT: radiotherapy; PLDR: pulsed low-dose rate; SD: standard deviation.
