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

The C-terminal domain of the RNA polymerase (RNAP) II largest subunit (CTD) plays a critical role in coordinating multiple events in pre-mRNA transcription and processing. Previously we reported that the peptidyl prolyl isomerase Pin1 modulates RNAP II function during the cell cycle. Here we provide evidence that Pin1 affects multiple aspects of RNAP II function via its regulation of CTD phosphorylation. Using chromatin immunoprecipitation (ChIP) assays with CTD phospho-specific antibodies, we confirm that RNAP II displays a dynamic association with specific genes during the cell cycle, preferentially associating with transcribed genes in S phase, while disassociating in M phase in a matter that correlates with changes in CTD phosphorylation. Using inducible Pin1 cell lines, we show that Pin1 overexpression is sufficient to release RNAP II from chromatin, which then accumulates in a hyperphosphorylated form in nuclear speckle-associated structures. In vitro transcription assays show that Pin1 inhibits transcription in nuclear extract, while an inactive Pin1 mutant in fact stimulates it. Several assays indicate that the inhibition largely reflects Pin1 activity during transcription initiation and not elongation, suggesting that Pin1 modulates CTD phosphorylation, and RNAP II activity, during an early stage of the transcription cycle.
