Fig. 5: PGE2-JNK signaling axis promotes intestinal tumor growth by non-canonically stimulating Hh activity in a Smo-independent manner in ApcMin/+ mice.

A, B The intestinal polyp number and size in ApcMin/+ mice treated with PGE2,GDC,SP, and JQ1 as indicated for 2 months. Error bars represent SD (n = 6). C The mRNA levels of Gli target genes in small intestine of mice treated with PGE2, GDC, SP, and JQ1 as indicated for 2 months. Error bars represent SD (n = 6). D Schematic model depicting the activation of Hh signaling pathway in cancer cells and stromal cells in colorectal cancer.
