Figure 1.

p-mTOR and PKM2 expression scores in the tumor group are higher than control group. A, p-mTOR antibody-stained nontumoral tissues and tumor tissues (magnification, ×200). p-mTOR shows high score in tumor tissues than in nontumoral tissues. B, PKM2 antibody-stained nontumoral tissues and tumor tissues (magnification, ×200). Tumor tissues show high score than nontumoral tissues. The bar plots show the score of the antibody-stained areas that were stained with the same antibody in nontumoral tissues and tumor tissues. Values are means (SD; n = 30, ** P < .01). mTOR indicates mammalian target of rapamycin; PKM2, pyruvate kinase M2 isoform; p-mTOR, phospho-mTOR; SD, standard deviation.
