Figure 5. Overexpression of iRhom1 does not prevent the depletion of mature ADAM17.

Figure 5

(A) The influence of PMA on ADAM17 in HEK293 cells overexpressing iRhom1 was analysed. Therefore, cells were transfected either with an empty vector (vec) or with iRhom1_M6P (iR1). After 48 hours cells were left unstimulated (unstim) or were stimulated with 100 nM PMA for 5 minutes. 8 hours or 24 hours after PMA stimulation the cells were harvested. Glycosylated proteins were enriched by precipitation with ConA-Sepharose and immunoblotted. (B,C) Amount of mature ADAM17 and its proform was measured by densitometry of immunoblots (A). The results are mean values of three independent experiments. (B) Shown are the ratios of mature ADAM17 to the total amount of ADAM17 normalised to unstimulated and untransfected cells (vec/0 h). (C) Comparison of the rate of downregulation and recovery. Each setup (vector and iRhom1 overexpression) was normalised to its initial amount of mature ADAM17 (0 h).
