doi: 10.64898/2026.01.15.699725

Figure Lengend Snippet: (A) Representative IHC staining of ITGB3 in PDAC tissue microarrays (TMA) showing varying expression levels in non-cancer and cancer tissue sections. (B). High magnification IHC images demonstrating the expression of ITGB3 on normal pancreas and cancer cells with stromal regions. (D-I) . Scatter plots depicting the correlation between ITGB3 and key tumor-associated markers such as HIF-1α (D) , GLUT-1 (E) , VEGFA (F) , Vimentin (G) , COL1A1 (H) , and PECAM1 (I) . Pearson correlation coefficients (R) and p -values indicate statistically significant positive correlation between ITGB3 and these markers. Statistical significance was assessed using a two-tailed unpaired Student’s t-test. All quantitative data represent the mean ± SEM. ∗∗∗∗p < 0.0001.

Article Snippet: To evaluate the role of ITGB3 in PDAC, we analyzed its expression using IHC in a human PDAC tissue array (PA483-L97, Biomax) that contains 40 cancer and eight non-cancer tissues ( Supplementary Table 1 ).

Figure Lengend Snippet: CBX family genes expression in colon cancer. ( A ) CBX expression level by qRT-PCR in three colon cancer cell lines (CACO-2, SW480, and HCT 116) compared to a normal colon cell line (NMC 460D). ( B ) CBX gene expression level in a colon cancer cDNA RT-qPCR array consisting of tumor ( N = 40) and normal samples ( N = 8). ( C ) Expression analysis of CBX family genes of colon tumor in UALCAN dataset (Normal = 41, Primary Tumor = 286). The star symbol indicates statistical significance (**: p ≤ 0.01, ***: p ≤ 0.001, ****: p ≤ 0.0001).

Figure Lengend Snippet: Characterization of CBX4 in CRC organoids. ( A ) Representative images of ex vivo PDO culture obtained from colorectal cancer biopsies are reported. Scale bar: 10 µm. ( B ) Real-time qPCR analysis of CBX4 in two groups of PDOs: the first one derived from healthy tissues (CNT) and the second one derived from tumor tissues (Tumor). Results were normalized to RPS18 mRNA and analyzed by 2 −ΔΔCt method. ( C ) Analysis of the knockdown efficiency of siCBX4 assessed by RT-PCR in PDOs after 72 h. ( D ) Effect of CBX4 silencing on PDO viability assessed by ATP Lite assay after 72 h. The star symbol indicates statistical significance (**: p ≤ 0.01).
