Fig. 4From: 10-hydroxy-2-decenoic acid of royal jelly exhibits bactericide and anti-inflammatory activity in human colon cancer cellsEffect of 10-HDA on human IL-1ra production in WiDr cells. Supernatants of WiDr cultures, treated with or without 10-HDA (0.1, 0.5, 1, 2, 3, and 5 mM), were collected after 24 h and tested by ELISA for detecting IL-1ra. CTL represents the control group (without 10-HDA). Each point is a mean ± SD of the triplicates from one representative experiment. * = p ≤ 0.05 compared to controlBack to article page
