Fig. 6From: RETRACTED ARTICLE: Circular RNA circ-CSPP1 regulates CCNE2 to facilitate hepatocellular carcinoma cell growth via sponging miR-577Circ-CSPP1 knockdown inhibits tumor growth in xenograft mice. a circ-CSPP1 expression was determined by qRT-PCR. (B) After 21 days, the tumor nodules were removed and photographed. b, cTumor weight and tumor volume were measured after circ-CSPP1 silencing. d The expression levels of Ki67, CCNE2, p-Rb, E2F1 and c-myc in tumors were determined by IHC (magnification, ×400; scale bar: 50 µm). *p < 0.05; **p < 0.01 and ***p < 0.001Back to article page
