LTC4-induced 15-PGDH promotes differentiation in transgenic zebrafish xenografts.a Schematic diagram showing the experimental setup of HT-29 cell-based xenografts in transgenic zebrafish (n = 20 in each group). b Immunofluorescence analysis of whole-mount staining of xenografted transgenic zebrafish Tg(fli1:EGFP) embryos with anti-Mucin-2 antibodies after the injection of shCTRL- or shGLI1-transfected HT-29 cells with or without LTC4 stimulation into the perivitelline space (PVS)53. c Graphical representation of the mean fluorescent intensity of Mucin-2-expressing HT-29 colon cancer cells transfected with shCTRL or shGLI1 with or without LTC4 stimulation. The scale bars are as indicated in the images. d Schematic mechanistic model described in the study. Mean ± SEM, **P < 0.01.
