Effects of 2-methoxystypandrone (2-MS) on Janus kinase 2 (JAK2) and activities of other human kinases. (a) HeLa cells were incubated with indicated concentrations of 2-MS for 2 h before stimulation with interleukin-6 (IL-6) (30 ng/mL) for 15 min. Whole cell lysates were processed for western blot analysis and probed with anti-P-JAK2 (Y1007/1008), anti-JAK2 or anti-GP130 antibodies. Anti-α-Tubulin antibody was used as a loading control. (b) HeLa cells were incubated with indicated concentrations of 2-MS for 2 h before being processed for western blot analysis. (c) In vitro kinase assay of JAK2. JAK2 protein immunoprecipitated from HeLa cells was subjected to in vitro kinase assay in the presence of indicated concentrations of 2-MS. (d) Effects of 2-MS on activities of human kinases. In vitro kinase assays were processed by Millipore Kinase Services. (e) In vitro kinase assay of IKKβ. IKKβ protein immunoprecipitated from HEK293 cells was subjected to in vitro kinase assay in the presence of indicated concentrations of 2-MS.
