Antiproliferative effect of a synthetic aptamer mimicking androgen response elements in the LNCaP cell line.
Article in Cancer gene therapy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Prostate cancer usually develops to a hormone-refractory state that is irresponsive to conventional therapeutic approaches. Therefore, new methods for treating aggressive prostate cancer are under development. Because of the importance of androgen receptors (ARs) in the development of the hormone-refractory state and AR mechanism of action, this study was designed. A single-stranded DNA as an aptamer was designed that could mimic the hormone response element (HRE). The LNCaP cells as an AR-rich model were divided into three sets of triplicate groups: the test group was transfected with Aptamer Mimicking HRE (AMH), Mock received only transfection reagents (mock) and a negative control. All three sets received 0, 10 and 100 nM of dehydroepiandrosterone (DHEA) separately. Data analysis showed hormone dependency of LNCaP cells in the negative control group upon treatment with 10 and 100 nM DHEA (compared with cells left untreated (P=0.001)). Transfection of AMH resulted in significant reduction of proliferation in the test group when compared with the negative control group with 10 (P=0.001) or 100 nM DHEA (P=0.02). AMH can form a hairpin structure at 37 °C and mimic the genomic HRE. Hence, it is capable of effectively competing with genomic HRE and interrupting the androgen signaling pathway in a prostate cancer cell line (LNCaP).
