Figure Lengend Snippet: Fig. 2 CAFs increases COL17A1 expression in GEM-resistant PC cells. A GSE192907 dataset showed that COL17A1 was highly expressed in resistant CAFs. B Western blotting analysis for COL17A1 expression in PANC-1/GR and BxPC-3/GR cells incubated with NF-CM or CAF-CM. C–E TCGA, CPTAC and GEPIA databases showed that COL17A1 expression was higher in PAAD tissues compared with the normal samples. F Kaplan–Meier Plotter predicted that high COL17A1 expression was associated with shorter survival times in PAAD patients. G qRT-PCR anal- ysis for COL17A1 expression in GEM-resistant or -sensitive PC tissues. H Western blotting analysis for COL17A1 expression in normal HPDE, parental PANC-1 and BxPC-3 cells as well as PANC-1/GR and BxPC-3/GR cells. *P < 0.05

(A–B) Effect of LV-GFP transduction on the cell viability of PDAC cell lines (MIA PaCa-2, BxPC3, Panc-1, SW1990 (basal-like subtypes, circles) and CFPAC-1, Capan-1, and HPAF-II (classical subtypes, squares)) (A) and PDX-derived primary PDAC cells (ST-7599, ST-7270, and ST-14490) (B). Human normal fibroblasts (BJ6) and HPDE cells (H6c7) were used as controls. The percentage of live cells was calculated using D Horizon™ Fixable Viability Stain 660 by flow cytometry. Statistical significance was computed through linear regression model coefficients (p > 0.05, ).

The dependence of the fraction of GFP-expressing cells to the number of viral IFU/cell were fitted with a second-degree polynomial regression model. Statistical significance was computed through ANOVA to test whether there were any significant interactions of categorical variables (cell types) in the regression models estimating the relationships of the percentage of GFP-expressing cells to the number of viral IFU/cell used ( for p-value).

Figure Lengend Snippet: Comparison of transduction efficiencies between LV-GFP and SeV-GFP. Transduction efficiencies are compared in control cell lines (HT1080, BJ6, and H6c7) (A), classical subtype PDAC lines (CFPAC-1, Capan-1, and HPAF-II) (B), basal-like subtype PDAC lines (MIA Paca-2, BxPC3, Panc-1, and SW1990) (C), and PDX-derived primary PDAC cells (ST-7599, ST-7270, and ST-14490) (D). The IFU/cell is calculated based on LV-GFP and SeV-GFP titer in corresponding cells. Each experiment was repeated at least three times independently (n ≥ 3). A second-degree polynomial regression model fitted the dependence of the fraction of GFP-expressing cells on the number of viral IFU/cell used. Statistical significance was computed through ANOVA to test whether there are any significant interactions of categorical variables (viral vector type) in the regression models estimating the relationships of the percentage of GFP expressing cells to the number of viral IFU/cell used ( for p-value).

Figure Lengend Snippet: Relative transduction efficiencies of LV-GFP and SeV-GFP in PDAC cell lines and PDX-derived primary PDAC cells. The relative transduction efficiencies of LV and SeV vectors in PDAC cells (cell lines or primary cells) were calculated by normalizing titers obtained from PDAC cells to the titers obtained on the control H6c7 HPDE cells (n = 3). Statistical significance was computed with the nonparametric Mann-Whitney U test. The relative transduction efficiency of SeV-GFP was significantly higher than that of LV-GFP across all tested PDAC cells (Mann Whitney U test, p < 0.05 ). The relative transduction efficiency of LV-GFP was significantly lower in the classical subtype than in the basal-like subtype of PDAC (Mann Whitney U test, p = 0.04 ). In contrast, there was no difference in the relative transduction efficiencies of SeV-GFP between classical and basal-like subtypes of PDAC cells (Mann Whitney U test, p = 1 ). Basal-like subtype PDAC lines (MIA Paca-2, BxPC3, Panc-1, and SW1990); classical subtype PDAC lines (CFPAC-1; Capan-1; HPAF-II; Primary PDAC cell (ST-7599; ST-7270; ST-14490); foreskin fibroblast BJ6; HPDE cell (H6c7). Since the presented data are not the result of direct measurements and do not satisfy all propagation of error requirements , the standard deviations are not shown.
