doi: 10.1111/jcmm.70913
Figure Lengend Snippet: SNHG26 is upregulated in colorectal cancer and knockdown inhibits proliferation. (A) Relative SNHG26 expression in colorectal cancer tissues compared to adjacent normal tissues across eight cohorts. (B) Relative SNHG26 expression in colorectal cancer cell lines (HT29, SW620, DLD1, HCT116 and SW480) and normal colon epithelial cell line FHC. (C) Knockdown efficiency of SNHG26 using two independent siRNAs (si‐SNHG26#1 and si‐SNHG26#2) in HCT116 and SW480 cells. (D, E) Cell proliferation assessed by CCK‐8 assay in HCT116 cells (D) and SW480 cells (E) after SNHG26 knockdown. (F, G) Colony formation assay results in HCT116 and SW480 cells following SNHG26 knockdown. Representative images (F) and quantification (G) are shown. (H, I) EdU incorporation assay showing DNA synthesis in HCT116 and SW480 cells after SNHG26 knockdown. Representative images (H) and quantification (I) are shown. (J‐K) Flow cytometry analysis of apoptosis in HCT116 and SW480 cells after SNHG26 knockdown. Representative plots (J) and quantification (K) are shown. * p < 0.05, ** p < 0.01, *** p < 0.001.
