Figure Lengend Snippet: LncRNA SNHG12 was carried by CAFs-EVs into NSCLC cells. A: qRT-PCR was used to detect the expression of SNHG12 in human NSCLC cell lines (A549, HCC44) and human normal lung epithelial cell BEAS2B; B: qRT-PCR was performed to examine the expression of SNHG12 in CAFs-EVs or NFs-EVs and the expression of SNHG12 after the addition of GW4869 into CAFs or NFs; C: qRT-PCR was conducted to detect the expression of SNHG12 in NSCLC cells after CAFs-EVs treatment to A549 and HCC44; D: Rnase A or Rnase A in combination with Triton X-100 was conducted to treat CAFs-EVs, and qRT-PCR was used to detect the expression of SNHG12 in CAFs-EVs; E: CAFs transiently transfected with Cy3-SNHG12 were co-cultured with A549 or HCC44 44 cells for 48 h, and fluorescence microscope was used to verify the fluorescence signal in NSCLC cells. The cell experiment was repeated 3 times independently, and data were expressed as mean ± standard deviation. Data in panels A-B and D were analyzed using one-way ANOVA. Data in panel C were analyzed using two-way ANOVA, followed by Tukey’s post-hoc test, * p < 0.05.

Figure Lengend Snippet: miR-145 and miR-143 Are Significantly Downregulated In Lung Cancer Cells Compared with Normal Lung Epithelial Cells and Cardiomyocytes (A and B) Expression levels of miR-145 (A) and miR-143 (B) in human normal lung epithelial cells (BEAS2B and primary lung epithelial cells), cardiomyocytes (HL-1 mouse cardiomyocytes and human induced pluripotent stem cell-derived cardiomyocytes [iCMs]), KRAS mut non-small-cell lung cancer (NSCLC) cells (H2030, H23, and A549), TP53 mut /RB1 mut small-cell lung cancer (SCLC) cells (H524 and H526), and HeLa cells were measured by qRT-PCR and calculated using the equation RQ (relative quantity) = 2 −ΔΔCt . The results are presented as mean ± SD (n = 3). One-way ANOVA was used to assess the differences among different cell types. *p < 0.05, # p < 0.01, & p < 0.001. (C) Construction of miRNA-modified CVB3 (miR-CVB3). Four copies of miR-145 (5′-AAGGGATTCCTGGGAAAACTGGAC-3′) and two copies of miR-143 (5′-GAGCTACAGTGCTTCATCTCA-3′) target sequences were inserted between the 5′ UTR and VP4 of the CVB3 genome. A Kozak sequence was added before the start codon (ATG) of VP4 to facilitate the translation of viral protein in cancer cells.

Figure Lengend Snippet: Both WT-CVB3 and miR-CVB3 Potently Destroy SCLC Cells, whereas Human Normal Lung Epithelial Cells Are Not Permissive to Either WT-CVB3 or miR-CVB3 (A–D) TP53 mut /RB1 mut SCLC cell lines (H524 and H526; A and B) and human normal lung epithelial cells (BEAS2B; C and D) were sham infected or inoculated with WT-CVB3 or miR-CVB3 at different MOIs as indicated for 72 h. Cell morphology was examined by light microscopy (original magnification, ×10; A and C). Cell viability was measured by the alamarBlue assay (mean ± SD, n = 3; B and D). An unpaired Student’s t test was used to assess the difference between cells treated with miR-CVB3 and WT-CVB3. *p < 0.05, # p < 0.01 compared to WT-CVB3.
