Infection with the human liver fluke Opisthorchis viverrini induces cancer of the
bile ducts, cholangiocarcinoma (CCA). Injury from feeding activities of this
parasite within the human biliary tree causes extensive lesions, wounds that
undergo protracted cycles of healing, and re-injury over years of chronic
infection. We show that O. viverrini secreted proteins accelerated wound
resolution in human cholangiocytes, an outcome that was compromised following
silencing of expression of the fluke-derived gene encoding the granulin-like
growth factor, Ov-GRN-1. Recombinant Ov-GRN-1 induced angiogenesis and
accelerated mouse wound healing. Ov-GRN-1 was internalized by human
cholangiocytes and induced gene and protein expression changes associated with
wound healing and cancer pathways. Given the notable but seemingly paradoxical
properties of liver fluke granulin in promoting not only wound healing but also a
carcinogenic microenvironment, Ov-GRN-1 likely holds marked potential as a
therapeutic wound-healing agent and as a vaccine against an infection-induced
cancer of major public health significance in the developing world.
