Figure Legend Snippet: ( A ) Determination of ING4 protein levels in 10 cancer tissues and paired non-cancerous normal colon tissues by western blot. ( B ) Real time PCR showed the differences of the raw delta Ct values of ING4 amplification after normalization by GAPDH in cancers and paired normal tissues. ( C ) Representative images of ING4 immunohistochemical staining in TMAs were shown. Note: Top panel: original magnification, × 50; bottom panel: original magnification, × 200. ( D ) The distribution of the difference in staining intensities of ING4 in CRC tissues compared with that in paired normal tissues. C, CRC tissues; N, paired non-cancerous colon tissues. ( E ) Kaplan–Meier curves showed overall survival of CRC according to expression levels of ING4.

Figure Legend Snippet: ( A – B ) Western blot was used to test the ING4 expression in the p53 +/+ HCT116 and HCT15 cells with ING4 overexpression (HA-ING4), ING4 knockdown (mi-ING4) and respective vector control (HA-Vec and mi-Vec). ( C ) ING4 in CRC cells negatively regulated tube formation. ( D – E ) Numbers of complete tubular structures formed by HUVECs were counted for ING4 overexpressed, knocked down and control groups ( n = 3/group) in CRC cells.

Data are presented as means ± standard deviations. * P < 0.05, ** P < 0.001 (Student's t -test).

Figure Legend Snippet: ( A ) Western blot confirmed that ING4 inhibited the expression of nuclear Sp1. ( B ) ING4 altered the DNA affinity of Sp1. EMSA was performed using nuclear protein extracts from p53 +/+ HCT116 transfected with ING4 overexpression (HA-ING4), knockdown (mi-ING4) and respective controls plasmids (HA-Vec and mi-Vec). Lane 1 contains no nuclear extracts. All other lanes contain 1μg nuclear extracts. Lane 6 represents competition analysis using 100-fold unlabeled Sp1 probes. The super shift band was observed when the Sp1 antibody was added (lane 7) and IgG was used as negative control for super shift (lane 8). ( C – D ) Real time PCR and western blot were used to explore the expressions of Sp1 downstream pro-angiogenic genes MMP-2 and COX-2 in ING4 over-expressed, knocked down and control p53 +/+ HCT116 cells. ( E ) The increased expressions of MMP-2 and COX-2 by ING4 knockdown were abolished by Sp1 siRNA (si-Sp1). ( F ) Conditioned medium was collected and applied in tube formation. ( G ) Numbers of complete tubular structures formed by HUVECs were counted for ING4 knockdown, Sp1 knockdown or co-knockdown and control groups in p53 +/+ HCT116 ( n = 3/group). ( H ) Photographs of matrigel plugs with ING4 knockdown, Sp1 knockdown or co-knockdown and control p53 +/+ HCT116 cells excised from mice after 10 days of growth in vivo . ( I ) The expressions of ING4, Sp1, MMP-2 and COX-2 were examined by western blot in matrigel plugs containing ING4 knockdown, Sp1 knockdown or co-knockdown and control p53 +/+ HCT116 cells. Data are presented as means ± standard deviations. * P < 0.05, ** P < 0.001 (Student's t -test).

Figure Legend Snippet: ( A – B ) ING4 overexpression (HA-ING4) significantly enhanced but ING4 knockdown (mi-ING4) decreased the degradation of Sp1. p53 +/+ HCT116 cells were transfected with ING4 overexpression, knockdown and respective controls plasmids 48 hours, respectively, followed by exposure to cycloheximide (CHX; 50 mg/ml) for 0, 4, 8 or 12 hour, and the whole-cell lysates were detected by western blot. ( C – D ) The intensity of the Sp1 protein bands was analyzed by densitometry, after normalization to the corresponding beta-actin level. ( E ) Ubiquitination of Sp1 was induced by ING4. The p53 +/+ HCT116 cells were transfected with GFP-ub together with HA-Vec or HA-ING4 plasmids for 48 hour and then pretreated with MG132 (10 μM) for 6 hour, and these whole-cell lysates were immunoprecipitated using anti-Sp1 antibody, and ubiquitination was detected with ubiquitin antibody. Endogenous Sp1 were examined by western blot. ( G ) The intensity of the Sp1 ubiquitin bands was analyzed by densitometry. The data are means ± standard deviations from three independent experiments. * P < 0.05, ** P < 0.001 (Student's t -test).

Figure Legend Snippet: ( A ) ING4 increased p21 expression. The expressions of cell-cycle associated proteins, such as cyclin A, cyclin E, CDK2, p21 and p27 in the p53 +/+ HCT116 cells with ING4 overexpression (HA-ING4) or knockdown (mi-ING4) and the respective controls (HA-Vec and mi-Vec). ( B ) ING4 regulated expressions of p21 and Sp1 regardless of p53 status. The expressions of p53, p21, Sp1 and histone H1, a sensitive protein for cyclin/CDK2 complexes phosphorylation activity, in the p53 +/+ HCT116 and p53 −/− HCT116 cells with ING4 overexpression or knockdown and the respective controls. ( C ) ING4 regulated p21 mRNA expression. The mRNA expressions of p21 in the p53 +/+ HCT116 and p53 −/− HCT116 cells with ING4 overexpression or knockdown and the respective controls was determined by real time PCR. ( D ) ING4 regulated p21 promoter activity. The reporter gene assay was used to test the p21 promoter activity in the p53 +/+ HCT116 and p53 −/− HCT116 cells with ING4 overexpression or knockdown and the respective controls.

The expressions of p21 and Sp1 were tested in the p53 +/+ HCT116 cells transfected with p21 overexpression (GFP-p21) together with ING4 knockdown and the control plasmids.
