Figure 3. Knockdown of NKILA promotes tumor growth in nude mice. (A) Tumor growth curve of Eca109 cells after knockdown of NKILA. (B) The dissected tumors from the nude mice was photographed. (C) Weight of dissected tumors was recorded. (D) Expression level of NKILA in the dissected tumors was detected by qPCR. (E) Immunohistochemical analysis of Ki-67 in the dissected tumors. Left panel was representative images and right panel was statistical quantification. Data in A, C, D and E represents the mean ± SD of six mice. *P < 0.05.
