A. qPCR analysis of CaMKIIδ expression after 3h IL-6/sIL-6r treatment following a 30-minute treatment with 2 μM ruxolitinib. n = 4, Two-way ANOVA, p < 0.05 B. Immunoblot of confluent HUVEC treated with or without 2 μM ruxolitinib and 3, 24h IL-6/sIL-6r treatment. Normalization of pan-CaMKII expression relative to the β-actin expression is shown. n = 3, Two-way ANOVA, (*) p < 0.05.
