In addition, FMT from butyrate-treated donors tended to decrease fasting plasma levels of glucose (–11%, P = 0.07; Figure 2E) and insulin (–25%, P = 0.07; Figure 2F) and markedly reduced homeostatic model assessment of insulin resistance (HOMA-IR) (–32%, P < 0.05; Figure 2G) in recipient mice. Here, INS is linked to Insulin resistance.
