Figure Lengend Snippet: A CT26 CRC cells were stained with PKH26GL (red) and quinacrine (green) fluorescent dyes. Images were acquired using confocal microscopy at time 0 and after 5 min following P2X7 activation with 300 µM BzATP and are extrapolated from a 30-min time course (see supplementary videos and ). B CT26 cells were pre-treated with P2X7 antagonist AZ10606120 (5 µM) for 10 min before application of BzATP. C Number of vesicles released in 30 min from CT26 cells in PBS vehicle (PBS S-VS), following stimulation with P2X7 agonist ATP (P2X7-VS) or 10 min pretreatment with P2X7 antagonist AZ10606120 followed by stimulation with 3 mM ATP (AZ-VS) ( n = 5). D Size of PBS S-VS, P2X7-VS, and AZ-VS ( n = 5). E Number of vesicles released in 30 min from CT26 cells in DMSO vehicle (DMSO S-VS), following stimulation with P2X7 agonist ATP (P2X7-VS) or 10 min pretreatment with P2X7 antagonist A740003 followed by stimulation with 3 mM ATP (A74-VS) ( n = 7). F Size of DMSO- S-VS, P2X7-VS, and A74-VS ( n = 7). G Western blot for GM130, Alix, P2X7, CD39, CD73, and A2A in CT26 cells, S-VS and P2X7-VS. Pericellular ATP was measured with the pmeLUC probe expressed on the cell surface of untreated CT26 cells or after 5 min of exposure to PBS vehicle, S-VS, and P2X7-VS ( n = 4). H Quantification of luminescence changes was expressed as a fold increase on time 0. I Representative images of photon emissions. Changes in ATP J concentration increase on time 0 in the supernatants of CT26 cells, untreated or treated with PBS vehicle, S-VS, or P2X7-VS, measured with a luciferin/luciferase assay ( n = 3). Changes in adenosine K concentration increase on time 0 in the supernatants of CT26 cells untreated or treated with PBS vehicle, S-VS, P2X7-VS, or P2X7-VS plus 5uM CD73 inhibitor AB680 ( n = 5). * p < 0.05, ** p < 0.001, *** p < 0,0001, **** p < 0.00001.

Article Snippet: Tissue slides from the mouse lungs and rat colons were analyzed for P2X7, CD39, CD73, and A2A expression using the following primary antibodies: P2X7 1:100 (P8232, Sigma-Aldrich), CD39 1:100 (NBP2-67230, Novus Biologicals, Minneapolis, Minnesota, USA), CD73 1:500 (MAB5795, R&D Systems, Minneapolis, Minnesota, USA), and A2A 1:100 (SC32261, Santa Cruz Biotechnology).

Figure Lengend Snippet: The mRNA expression of P2X7A A , B , P2X7B C , D , CD39 E , F , CD73 G , H , and A2A I , J was evaluated in the cDNAs of 158 patients with CRC subdivided into stage I ( n = 24), stage II ( n = 50), stage III ( n = 52), and stage IV ( n = 32) which comprised 11 samples derived from metastases in organs other than the colon. K Spearman’s correlation coefficient among P2X7A, P2X7B, CD39, CD73 , and A2A was evaluated in CRC metastatic patients. L Spearman’s correlation coefficient was evaluated between P2X7 and A2A expression in colon adenocarcinoma samples obtained from the Cancer Genome Atlas database. * p < 0.05, ** p < 0.01, *** p < 0.001. **** p < 0.0001.
