Androgen receptor coregulators NOCR1, TIF2, and ARA70 may account for the hydroxyflutamide insensitivity of prostate cancer cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionProstate cancer cells can switch from an androgen-dependent state to an androgen-independent state after a continuous androgen ablation therapy. However, the molecular mechanisms underlying this switch are still unclear. Therefore, we explored the change in androgen receptor (AR)-related gene expression during this transition in a novel cell model. MATERIAL AND
methodsProstate cancer cells were continuously treated with competitive androgen receptor inhibitor hydroxyflutamide for 1.5 years, which yielded an flutamide-insensitive LNCaP subline, LNCaP-flu, as confirmed by MTT assays, flow cytometry, and electron microscopy. We analyzed the differences in gene expression in LNCaP-flu cells and LNCaP cells using gene chips and follow-up RT-PCR.
resultsOver 2,428 genes were differentially expressed between these cell lines: 1,194 were down-regulated and 1,234 were up-regulated. Three genes in particular were considered related to the androgen-dependent transition: NCOR1, TIF2 (NCOA2), and ARA70 (NCOA4). There were no apparent changes in expression of the androgen receptor or prostate-specific antigen.
conclusionARs and associated coregulators play a central role in the flutamide-insensitive transition of prostate cancer cells. Although AR expression does not change during this transition, the change in AR coregulators may be a critical factor in the development of antiandrogen insensitivity.
