Significance of 125I radioactive seed implantation on growth differentiation factor and programmed death receptor-1 during treatment of oral cancer

Figure 2 Changes in growth differentiation factor 11 and programmed death receptor-1 during treatment. A: Differentiation factor 11 during treatment in both groups; B: programmed death receptor-1 during treatment in both groups. a indicates comparison with T0 in the same group (^aP < 0.05); b indicates comparison with T1 in the same group (^aP < 0.05); c indicates comparison with T2 in the same group (^aP < 0.05); d indicates comparison with the RG at the same time (^aP < 0.05). PD-1: Programmed death receptor-1; GDF11: Growth differentiation factor 11.
