Expression and function of pro‐inflammatory interleukin IL‐17 and IL‐17 receptor in normal, benign hyperplastic, and malignant prostate
Abstract
INTRODUCTION AND OBJECTIVES: To investigate factors involved in inflammation of the prostate besides IL‐15, we screened prostatic cells and tissues for IL‐17 and IL‐17 receptor expression. METHODS: Normal prostate (n = 1), BPH (n = 19), and carcinoma (CaP, n = 12) specimens were screened for IL‐17, IL‐17 receptor, CD45, IL‐6, and IL‐8 mRNA expression. The carcinoma cell lines DU145, PC3, LNCaP, and BPH‐epithelial (EC), stromal cell (SC) preparations, and BPH‐T‐cell lines were analyzed for IL‐17 production by RT‐PCR and ELISA. The effect of IL‐17 on IL‐6, IL‐8, TGF‐β1, and fibroblast growth factor (FGF‐2) mRNA expression and/or release of SC was analyzed using real‐time PCR and/or ELISA. Immunohistochemistry was used to localize both IL‐17 and IL‐17 receptor. RESULTS: In the normal prostate, IL‐17 expression was very weak and restricted to lymphocytes. In 79% of BPH and 58% of CaP specimens, IL‐17 mRNA and protein expression was increased. IL‐17 mRNA expression could be shown for activated BPH‐T‐cells and to some extend for BPH‐EC. Expression of IL‐17 receptor was ubiquitous. Release of IL‐17 was shown only for activated BPH‐T‐cells. IL‐17 stimulated expression of IL‐6 (13‐fold) and IL‐8 (26‐fold) by prostatic BPH‐SC. In situ, however, the amount of IL‐17mRNA in BPH‐tissue did not correlate with the amount of IL‐6 and IL‐8 mRNA. In CaP tissue, significant correlation was found only between the amount of IL‐6 and IL‐8 mRNA. CONCLUSIONS: Activated BPH‐T‐cells abundantly express IL‐17. The increase of IL‐17 in BPH‐tissues goes hand in hand with elevated levels of IL‐15, a pro‐inflammatory cytokine with T‐cell growth factor properties. A clinical relevance of increased IL‐17 expression under pathological conditions is suggested by the demonstration of significant upregulation of IL‐6 and IL‐8 production of prostatic SC by IL‐17.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
