Figure 3. In vitro effect of arginine level on the expression of casein genes in mammary epithelial cells from lactating dairy cattle.

Figure 3

And: Panel A, CSN1S2 gene; and Panel B, CSN3 gene. Arg 0X, control without supplemental Arg (0.00 mg/L); Arg 0.25X, deficiency in casein (69.50 mg/L); Arg 0.5X, deficiency in casein (139.00 mg/L); Arg 1X, to match its concentration in casein (278.00 mg/L); Arg 2X, excess in casein (556.00 mg/L); Arg 4X, excess in casein (1,112 mg/L); and Arg 8X, excess in casein (2,224 mg/L). Different letters indicate significant difference between means (P<0.05).
