Given that Salmonella influences gene expression in tumors by modulating Akt/mTOR and MAPK signaling [19], we examined the effect of Salmonella treatment on the expression of SNAI1 in a panel of melanoma cell lines, as SNAI1 was known to be regulated, in part, by Akt signaling [9,10]. The gene discussed is MTOR; the disease is melanoma.
