5-AzadC reduced IL-1β-mediated cell proliferation.

FLS were treated with 5 ng/mL IL-1β alone for 4 days, or with IL-1β for 24 h and then with 1 μM 5-AzadC for 3 days, or without any treatments (control). Cell proliferation was estimated as described in the Materials and Methods. Cell growth was represented either individually (left) or on the average(right). #, comparison with the IL-1β group, p< 0.05.
