TRiC/CCT chaperonin governs RNA polymerase II activity in the nucleus to support RNA homeostasis.

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
Eukaryotic tailless complex polypeptide 1 ring complex/Chaperonin containing tailless complex polypeptide 1 (TRiC/CCT) chaperonin is typically considered a cytosolic machine mediating polypeptide folding and assembly of protein complexes. Here, we investigated the nuclear role of TRiC/CCT. Use of a TRiC/CCT temperature-sensitive allele revealed increased production of nascent RNA leading to the accumulation of noncoding transcripts. TRiC/CCT was associated with RNA polymerase II (RNAPII) in vitro and in vivo, including when bound to DNA. Heat treatment of the TRiC/CCT ts chaperonin stabilized the RNAPII complex association and binding to the actin and tubulin substrates. Expression of the Huntingtin protein Htt correlated with lowered RNA production and a decreased association between the RNAPII and TRiC/CCT complexes. Together, our presented data support a model where TRiC/CCT regulates the global activity of RNAPII in reaction to the status of proteostasis. Overall, our work reveals an avenue by which TRiC/CCT contributes to homeostasis by regulating the activity of nuclear RNAPII.
