Figure 8From: Continuous and low-energy 125I seed irradiation changes DNA methyltransferases expression patterns and inhibits pancreatic cancer tumor growthTumor volume 0 and 28 d after 125I seed implantation. The upper, middle, and lower panels show representative ultrasound images from 0 Gy (upper), 2 Gy (middle), and 4 Gy (lower) groups 0 and 28 d post 125I seed implantation. *P < 0.05 compared with 0 d post-implantation; ΔP > 0.05 compared with 0 d post-implantation.Back to article page
