-mannose-sensitive hemagglutinin inhibits chemical-induced skin cancer through suppressing hedgehog signaling.

UNLABELLED

-mannose-sensitive hemagglutinin (PAM) is an inactivate with mannose-sensitive hemagglutinin. Recently, the anticancer properties of PAM against many cancers have been reported across a range of studies. However, the exact mechanism through which PAM prevents skin cancer remains unclear. The aim of this study is to show to what extent PAM could inhibit the dimethylbenzanthracene (DMBA)/12-O-tetradecanoylphorbol-13-acetate (TPA)-induced skin cancer. JB6 cells were treated by TPA so as to establish an model. The effects of PAM on proliferation of the cells were analyzed using cell counting kit-8 assays. Effects on epithelial–mesenchymal transition (EMT) were assayed by real-time PCR and Western blotting. A DMBA/TPA-induced skin cancer mouse model was also established. The results showed that TPA promoted EMT changes through the activation of the hedgehog (Hh) pathway, which was reversed by PAM. Moreover, PAM inhibited the cancer growth and Hh pathway . These data indicate that PAM may serve as a potential anticancer agent for the treatment of skin cancer.

IMPACT STATEMENT

-mannose-sensitive hemagglutinin (PAM) restrained the chemical-induced skin cancer cells and partly through suppressing the Hh signaling pathway, indicating that PAM may be a promising anticancer agent for treating skin cancer.
