Effect of size-based CWE fractions on signaling molecules. Peritoneal macrophages were 1 h pretreated with 120 μg/ml of low molecular weight(MW) fraction(L), 30 μg/ml of middle MW fraction (M), and 50 μg/ml of high MW fraction (H) according to the yield ratio relative to total CWE. After LPS stimulation for 15 min, signaling molecules in whole protein extracts were examined by Western blot analysis. One of the five experiments is shown.
