In this study, we investigated the effect of FTS on human AML cells, which were shown to serve as a model for LAM.7 Using a gene array method, we demonstrate that FTS, by targeting Rheb, can inhibit the function of IRF7 in AML cells, thereby mimicking the effects of rapamycin and re-expression of TSC2. This evidence concerns the gene RHEB and lymphangioleiomyomatosis.
