Figure 1. The expression of HOTAIR in human gastric carcinoma tissues.
A, HOTAIR expression levels of cancerous and adjacent noncancerous tissues from the gastric cancer patients were examined by qRT-PCR and normalized by the GAPDH expression level. The expression levels of HOTAIR were significantly higher in carcinoma lesions compared to those of non-cancerous lesions (P= 0.019). B and C, The human gastric cancer tissues were further classified according to the HOTAIR expression level into a High-HOTAIR group (HOTAIR / GAPDH >1.0) and Low-HOTAIR group (HOTAIR /GAPDH < 1.0) in the intestinal (B) and diffuse type (C) of gastric cancer, respectively.
