Fig. 1From: XIST promotes cell proliferation and invasion by regulating miR-140-5p and SOX4 in retinoblastomaExpression of XIST was examined in RB tissues and cells. a Expression of XIST was significantly upregulated in RB tissues. b XIST expression was remarkably upregulated in RB cells compared to human retinal epithelial cells. *P < 0.05, **P < 0.01, and ***P < 0.001, compared with normal tissues or the ARPE-19 groupBack to article page
