Figure 2. The mRNA expression of key genes involved in lactose synthesis in BMEC.

BMEC were treated for 12 h with various concentration of glucose. Values with different superscripts (a, b) are significantly different (P<0.05), and bars indicate the standard error of means (n = 4). BMEC: bovine mammary epithelial cells, B4GALT : beta-1, 4-galactosyl transferase, LA: α-lactalbumin.
