Dose-increased expression of cytokine genes. Transcriptional expression of H. leucospilota cytokines gene, with the β-actin as reference gene, in the sea cucumber coelomocytes treated respectively with LPS concentration of 10.0 μg/ml, 20.0 μg/ml, 50.0 μg/ml for 24 h. The data presented are expressed as the mean ± S.E. (n = 3). The same letter in the experimental groups represent a similar level (p > 0.05, ANOVA followed by Fisher’s LSD test)
