Significantly up-regulated and down-regulated genes are highlighted based on predefined statistical thresholds. ( B ) Summary of DEGs identified in the transcriptomic analysis, showing the numbers of significantly up-regulated and down-regulated genes in miR-196 knockout cells relative to control cells. The vertical dashed lines indicate the fold-change thresholds, and the horizontal dashed line represents the statistical significance threshold (adjusted p -value cutoff). The grey shaded area indicates genes that are not significantly differentially expressed. ( C ) Venn diagram illustrating the overlap of DEGs between miR-196A-KO and miR-196B-KO cells. A subset of genes was commonly regulated by both miR-196 isoforms, while additional genes were uniquely altered in each knockout condition.
