PTF1A and pancreatic adenocarcinoma: To generate a zebrafish model of pancreatic adenocarcinoma, eggs derived from Tg(ptf1a:Gal4) outcrosses were injected with Tol2(UAS:eGFP-KRASG12D) plasmid (Liu and Leach, 2011; Park et al., 2008); we call these samples “Tg(ptf1a:Gal4)/UAS:eGFP-KRASG12D injected”.
