Figure 3: ERK-like protein detection in Taenia crassiceps. Total ERK-like protein in T. crassiceps was not modified by 17-estradiol or ERK inhibitor treatments (a), contrary to that observed in ERK-like gene expression. Nevertheless, 17-estradiol specifically induced phosphorylation of ERK-like by four-fold respect to control groups (b). Optical densitometry was performed on 10% acrylamide gel from six independent experiments. Control Parasites treated with the vehicle where hormone and inhibitors were dissolved; .
