Abstract

Background It has been suggested that interleukin-6 (IL-6) may modulate androgen receptor (AR) action to accelerate prostate cancer (PCa) progression. Selenium compounds are highly recommended as a promising chemopreventive agent for PCa. This study was to determine if selenium can repress IL-6 mediated AR action in PCa progression.Methods Cell proliferation, prostate-specific antigen, gene transfer, and Western blot assays were used to study the effects of sodium selenite and methylseleninic acid on IL-6 mediated AR action on an AR expressing human prostate cancer cell line, LNCaP.Results We found that sodium selenite, but not methylseleninic acid, significantly (p<0.05) inhibited IL-6-induced trans-activating activity of AR and cell proliferation in LNCaP cells. Interestingly, although sodium selenite did not show effect on activation of both STAT3 and ERK1/2 in the presence of IL-6, an increased expression of c-Jun was detected in cells after treatment with sodium selenite. Indeed, we showed overexpression of c-Jun blocked IL-6-induced AR activation.Conclusions Taken together, our results suggest that sodium selenite not methylseleninic acid can inhibit IL-6-mediated AR activation by increased c-Jun in LNCaP cells. Sodium selenite may be a proper selenium form for further testing its potency on intervening IL-6-mediated PCa progression.

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.
