Fig 1. Gene expression of candidate transcription factors in bovine mammary epithelial cells.

(A) Gene expressions were measured at 24, 40, 48, 60 h after lysine or methionine subtraction to ¼ the normal concentration. (B) Values are least square means ± SE (n = 3) in arbitrary units. (C) CTL = control; LK = low lysine; LM = low methionine. (D) *P ≤ 0.05, ^†0.05 < P ≤ 0.15 compared to CTL.
