Figure Lengend Snippet: BUD23 knockdown suppresses the proliferative and migration of NSCLC cells. (A) RT-qPCR was used to quantify BUD23 mRNA levels in HBE cells and a panel of NSCLC cell lines. Validation of BUD23 knockdown efficiency in (B) A549 and (C) H1299 cells by RT-qPCR. Assessment of cell viability in (D) A549 and (E) H1299 cells via CCK-8 assay and cell migration in (F) A549 and (G) H1299 cells by wound healing assay (magnification, ×10). CCK-8 assays of (H) A549 and (I) H1299 cells 24 h after BUD23 knockdown with or without subsequent co-culture with Jurkat T cells for 48 h in Transwell chambers. (J) Quantification of apoptosis in A549 and H1299 cells via Annexin V/PI flow cytometry. **P<0.01 and ***P<0.001 vs. HBE, NC, Con or as indicated. NSCLC, non-small cell lung cancer; RT-qPCR, reverse transcription-quantitative PCR; HBE, human bronchial epithelial; CCK-8, Cell Counting Kit-8; NC, negative control; Con, control; Si1/2, small interfering RNA targeting BUD23.

Figure Lengend Snippet: BUD23 knockdown significantly downregulates POLR2J expression in non-small cell lung cancer. (A) Venn diagram showing the intersection between LUAD GSEA core enrichment genes (key genes driving Hallmark DNA repair pathway enrichment) and LUSC GSEA core enrichment genes within the Hallmark DNA repair gene set, identifying 49 common genes. (B) Venn diagram showing the intersection between BUD23-correlated genes (correlation index >0.3) derived from the TCGA-LUAD cohort and BUD23-correlated genes (correlation index >0.3) derived from the TCGA-LUSC cohort via multi-gene correlation analysis, yielding 79 overlapping genes. (C) Venn diagram showing the secondary intersection between the 49 overlapping GSEA core enrichment genes (from panel A) and the 79 overlapping BUD23-correlated genes (from panel B), identifying 4 shared common genes: TAF6, POLR2J, RFC2 and VPS37D. (D) Validation of TAF6, POLR2J, RFC2 and VPS37D mRNA expression following BUD23 knockdown in A549 cells via reverse transcription-quantitative PCR. Cell-cycle analysis in (E) A549 and (F) H1299 cells following BUD23 knockdown. ***P<0.001 vs. Con.
