PSA reduced IL-1βinduced IL-8 in H4 cells.

<p>H4 cells were pretreated with or without PSA at an optimal dose and then exposed to IL-1β or treated with PSA alone. The supernatants were collected to measure IL8 levels by Elisa. The mean and SEM were from triplicate wells and were representative of three separate experiments with similar results. **P<0.01 (one-way ANOVA and post-hoc tests).
