Figure Lengend Snippet: Identification of prognostic genes in NRS and Validation. (A) Forest plot shows prognosis-associated genes within NRS. (B) In George’s cohort, the distribution of high and low expression of NPPC. Cutting off value was determined using the survminer R package. High expression level of NPPC is associated with poor patient prognosis. (C,D) t-SNE visualization of cells shows the expression of NPPC and its receptor NPR2 in single-cell RNA-seq data. (E) Representative areas of HE and IHC of NPPC expression in tumorous tissues from three SCLC patients. Scale bar, 50 µm. (F-G) qPCR validation of NPPC and NPR2 expression across various human normal epithelial and SCLC cell lines. (H) Transwell migration assay of SCLC-1 cells treated with CNP-38 (product of the NPPC gene) or DMSO (control) for 12 hours (0.5% crystal violet dye, ×100). (I) Data processing and analysis of transwell migration assay. ***, P<0.001; CI, confidence interval; CNP, C-type natriuretic peptide; DMSO, dimethyl sulfoxide; HE, hematoxylin and eosin staining; IHC, immunohistochemistry; NPPC, natriuretic peptide C; NPR2, natriuretic peptide receptor B; NRS, nomogram/prognostic risk score; qPCR, quantitative polymerase chain reaction; RNA-seq, ribonucleic acid sequencing; SCLC, small cell lung cancer; t-SNE, t-distributed stochastic neighbor embedding.

Figure Lengend Snippet: ASPH is overexpressed in lung adenocarcinoma tissues and cell lines, and its silencing impairs tumour‐cell proliferation. (A) qRT-PCR analysis of ASPH mRNA levels in paired adjacent normal (“Adjacent”) and tumour (“Cancer”) lung specimens. ** P < 0.01 versus adjacent. (B) Basal ASPH expression measured by qRT-PCR in the normal bronchial epithelial cell line BEAS-2B and five LUAD cell lines (NCI-H1975, HCC827, A549, Calu-3, NCI-H2228). Data are mean ± SD; ns, not significant; ** P < 0.01; *** P < 0.001; **** P < 0.0001 versus BEAS-2B (C) Confirmation of ASPH knockdown in HCC827 and NCI-H2228 cells transfected with si-ASPH or non-targeting control (si-NC). Relative ASPH mRNA levels were quantified by qRT-PCR. Data are mean ± SD; ** P < 0.01; *** P < 0.001 versus si-NC. (D, E) CCK-8 assays showing growth curves of HCC827 (D) and NCI-H2228 (E) cells over 4 days post-transfection. OD₄₅₀ readings are plotted as mean ± SD from three independent experiments; ** P < 0.01; *** P < 0.001 versus si-NC at day 4.
