Effects of seminal plasma on cytokine mRNA expression by HeLa cells. Quantitative real-time PCR was used to determine the mRNA expression of (C) IL-6, (A) IL-8, (B) IL-1β, (E) GM-CSF, (D) MIP3α, and (F) VEGF by HeLa cells treated with 1:50 dilution of seminal plasma from HIV-negative (white bars) or HIV-positive individuals (black bars) for 8 h (n = 4) and 24 h (n = 3). The mRNA levels were normalized by housekeeping gene Human cyclophilin A. Data are represented as the mean ± SEM of duplicate wells in each experiment. Wilcoxon matched pairs (non-parametric) and standard matched pairs t-tests (parametric) were used to compare the control and treatment groups. *p < 0.05.
