Hepatic mRNA expression of FGF21, FGF21 binding, and genes associated with circadian rhythms and insulin signaling in control cows (n = 7) and cows induced to develop ketosis (n = 7) by undernutrition after calving.

1Calculated after normalization with the geometric mean of UXT, GAPDH and RPS9 (see materials and methods).Liver biopsy was performed at d 9 to 14 (ketosis induction) or 14 d postpartum (control) before the morning meal. The 95% confidence interval (CI) is reported.

1. 以UXT、GAPDH及RPS9的几何均值进行归一化处理后计算所得（详见材料与方法）。于妊娠第9至14天（酮症诱导阶段）或产后第14天（对照组）的晨间餐前实施肝脏活检。本研究报告了95%置信区间（Confidence Interval, CI）。
