Figure Lengend Snippet: IL-1α overexpression alters expression of IL-1 pathway genes. Gene expression of IL1B (A), IL6 (B), IL8 (C), IL1RN (D), IL1RAP (E) and IL1R1 (F) in the three IL1A constructs – Full-Length (FL), N-terminal (NT) and C-terminal (CT) in Cal27 IL-1αoverexpressing cells were analyzed by RT-PCR using GAPDH as an endogenous control. Protein secretion of IL-1β (G), IL-6 (H), IL-8 (I), and IL1RA (J) in cell culture supernatants was quantified by ELISA with protein concentrations normalized to cell numbers. Whole cell lysates were analyzed for IL-1R1 expression by Western blot using GAPDH as a loading control (K). Bars represent mean ± SEM from n = 3 independent experiments.∗p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001; ∗∗∗∗p < 0.0001.
