Translational inhibition of the alternative NOD2 5'UTR can be inhibited by rapamycin. Relative luciferase activities were determined from the construct containing both 5'UTR exons with and without deletion of the uAUGs (ΔATG1.2.3 and wildtype). Note the significant reduction of the inhibitory effect of the uORFs after rapamycin treatment (1 μM). Values represent mean ± SD calculated from three independent experiments. RLU, relative luciferase units, determined by dual luciferase assay *p < 0.05, Student's T-Test).
