1 · What the graph read from it

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.

2 · The registry

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

Despite multiple new-drug approvals in recent years, prostate cancer remains a global health challenge because of the prostate cancers are resistant to androgen deprivation therapy. Here we show that a small D-phosphopeptide undergoes prostatic acid phosphatase (PAP)-instructed self-assembly for inhibiting castration-resistant prostate cancer (CRPC) cells. Specifically, the installation of phosphate at the C-terminal of a D-tripeptide results in the D-phosphopeptide. Dephosphorylating the D-phosphopeptide by PAP forms uniform nanofibers that inhibit VCaP, a castration-resistant prostate cancer cell. A non-hydrolyzable phosphate analogue of the D-phosphopeptide, which shares similar self-assembling properties with the D-phosphopeptide, confirms that PAP-instructed assembly is critical for the inhibition of VCaP. This work, for the first time, demonstrates PAP-instructed self-assembly of peptides for selective inhibiting castration-resistant prostate cancer (CRPC) cells.
