MLE-12 cells were inoculated in 6-well plates and grown to 60% confluence. The cells were incubated with Coumermycin A1, JAK-IN-21, Colivelin TFA, and Stattic in culture medium for 48 h. The medium was then refreshed, followed by a 24-h pretreatment with EGCG, and finally exposure to LPS for 10 h. Protein levels of JAK2, p-JAK2, STAT3, and p-STAT3 were measured by western blotting.
