Figure 4.
Relative expression of butyrate-related genes in HCT (a) and PMF (b) cells. Expression (GPR109A, GPR109B, and SLC5A8) is shown relative to that of GAPDH. Data are expressed as means ± SD of triplicate experiments. Significant differences were determined using Student's t-test (∗p value<0.05, ∗∗p value<0.01).
