IL6 and hydrops fetalis: [23] In the present study, IL6 expression was substantially up-regulated in the liver of Ath+HF diet mice and STAMTM mice, and this induction of IL6 was predominant in older mice (from 38 weeks to 68 weeks in the Ath+HF diet model and 22 weeks in STAMTM mice) (Figure 2 and Supplemental Figure 2D).
