Figure Lengend Snippet: (A) Effect of ATP in cell migration comparing normal ciliated cholangiocytes (NHC SCR), normal deciliated cholangiocytes (NHC IFT88) and the CCA cell line HUCCT1. Representative images obtained from the wound healing assay and bar graphs showing the distance migrated by the cells relative to control (vehicle) in 24 h are depicted (**p<0.01, n=3). (B) Cell migration analysis by wound healing assay showing the effects of ATP, ADP, Apyrase and their combinations. Bar graph shows the distance migrated by the cells relative to control (vehicle) in 24 h (*p<0.05, **p<0.01, n=3). (C) Invasion assay, representative pictures and bar graph showing the percentage of invasion in 24 h (**p<0.01, n=3). (D) Proliferation rates were assessed in real time using IncuCyte or (E) by MTS assay. Results are expressed in % proliferation relative to control (vehicle).

Figure Lengend Snippet: (A) Expression of LKB1 was evaluated in normal cholangiocytes (NHC, H69), experimentally deciliated cholangiocytes (NHC IFT88, H69 IFT88) and CCA cell lines (KMCH, HUCCT1, OZ, EGI-1) by western blotting. (B) Presence of LKB1 in primary cilia using acetylated α-tubulin or ARL13b as ciliary markers. The expression was assessed by confocal immunofluorescence on scramble normal cholangiocytes (NHC SCR). (C) Western blot comparing the effect of ATP on LKB1 phosphorylation in normal cholangiocyte cell line (NHC SCR), experimentally deciliated cholangiocytes (NHC IFT88) and iCCA cell line (HUCCT1) (**p<0.01, n=3). (D) Western blots for p-LKB1 and total LKB1 showing the effect of pre-treatment (30 min) with suramin 100 μM or H89 20 μM on the treatment with ATP for 30 min. (E) NHC cells transfected with shRNA-LKB1 (NHC LKB1) or shRNA-scramble (NHC SCR). Expression levels of LKB1 protein were evaluated by western blot (**p<0.01, n=3) and the effect of ATP on migration was evaluated by wound healing assay (**p<0.01, n=3).

Figure Lengend Snippet: (A,B) Western blots showing the effect of ATP for 30 minutes on AKT and PTEN phosphorylation in normal ciliated cholangiocytes (NHC SCR), experimentally deciliated cholangiocytes (NHC IFT88), and the iCCA cell line HUCTT1. Bar graph shows densitometry expressed as % of phosphorylated/total ratios in control conditions (*p<0.05, n=3) (**p<0.01, n=3).

Figure Lengend Snippet: (A) F-actin and filopodia were evaluated by Phalloidin staining (red) in normal ciliated cholangiocytes (NHC SCR), experimentally deciliated cholangiocytes (NHC IFT88), the iCCA cell line (HUCCT1), and normal ciliated cholangiocytes with LKB1 knockdown (NHC LKB1), in the presence or absence of ATP. Nuclei were stained in blue with DAPI (Magnification X600). (B) Quantification of filopodia after treatment with ATP for 30–60 min is shown in bars representing the average number of filopodia per cell (**p<0.01 n=67).
