HOXC10 expression in human gastric cancer tissues. (A) HOXC10 mRNA expression in adjacent noncancerous tissues (N) and tumor samples (T) via reverse transcription-polymerase chain reaction (RT-PCR) and normalized against 18S mRNA expression, P=0.0045; (B) Representative images of HOXC10 immunohistochemical staining in human gastric carcinoma and noncancerous gastric tissues. (a, b) Normal gastric mucosa; negative HOXC10 expression; (c, d) Early gastric carcinoma; weak HOXC10 expression in nuclei and cytoplasm of gastric lesions; (e, f) Lymph node involvement with strong HOXC10 expression in nuclei; (g, h) Distant organs metastasis group of metastasis tumor; strong HOXC10 expression in nuclei and cytoplasm of gastric cancer cells. Images were taken using a 10× objective lens in a, c, e and g (scale bar = 100 μm) and 40× in b, d, f and h (scale bar = 200 μm).
