Expression of SAA in the mammary gland during gestation and lactation, as determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Upper panel: Profiles of bands obtained for SAA and cyclophilin in porcine MG. Lower panel: Kinetics of SAA mRNA production from the virgin state through gestation and lactation in porcine MG. The relative signal intensities were obtained by normalization with respect to the cyclophilin signal (mean ± SEM of 2–3 animals). (*) Levels of SAA mRNA did not vary during gestation or lactation, until day-80 of gestation, after which they increased significantly, reaching a peak on day 15 of lactation L15: p < 0.05 in Student's t tests.
