Effects of catechin extract, catechin nanoemulsion and paclitaxel on body weight (A), tumor volume (B) and tumor weight (C) as well as serum EGF and VEGF levels (D) of nude mice. E10 and E20 are catechin extract treatments at 10 and 20 mg/kg BW, respectively, with the same injection volume (0.2 mL), while N10 and N20 are catechin nanoemulsion treatments at the same dose. For paclitaxel treatment, an injection volume of 0.2 mL (10 mg/kg BW) was used. Data are shown as mean ± standard deviation of triplicate analyses (n = 3), with data bearing different capital letters (A–E) in Figure 5C,D and small letters (a–d) in Figure 5D to denote significantly different values at p < 0.05.
