Figure 7. OA inhibited the breast tumor growth in mice. (A) The total body weights of five mice were compared between the CK group (n = 5) and OA group (n = 5) every day during the feeding process. (B) The bioluminescence intensity of breast tumors in three CK mice and three OA mice was observed by a Tanon-5200 Multifluorescence imaging analysis system. (C) The tumor sizes of three CK mice and three OA mice were measured by rulers. (D) The tumors from the CK group and OA group were weighed and compared (n = 5), **P < 0.01. (E) Validation of target gene expression in mice from the CK group and OA group tested by qPCR, *p < 0.05, **P < 0.01.
