Effect of intravasal LPS (25 μg) or LTA (125 μg) treatment on the mRNA levels of pro-inflammatory genes in the cauda epididymis. (a,b) Relative quantification of Il6, Ifng, Nos2 and Ptgs1 transcripts by RT-qPCR in the cauda epididymis from saline-control, LPS- or LTA-treated rats euthanized 6 h or 24 h after treatment. Samples were normalized to their internal control (Ppia) and expressed as relative values of their respective saline-control groups. Asterisks indicate statistically different from saline-control group (p < 0.05, Student’s t test). Results are expressed as mean ± SEM of experiments performed in duplicate with samples from five (24-h saline-control) or six (6-h saline-control, LPS- and LTA-treated groups) rats per group in (a) and five (6-h saline-control and 24-h LTA) or six (24-h saline-control and 6-h LTA) rats per group in (b).
