Inhibition of HDAC6 activity through interaction with RanBPM and its associated CTLH complex.
Article in BMC cancer, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundHistone deacetylase 6 (HDAC6) is a microtubule-associated deacetylase that promotes many cellular processes that lead to cell transformation and tumour development. We previously documented an interaction between Ran-Binding Protein M (RanBPM) and HDAC6 and found that RanBPM expression inhibits HDAC6 activity. RanBPM is part of a putative E3 ubiquitin ligase complex, termed the C-terminal to LisH (CTLH) complex. Here, we investigated the involvement of the CTLH complex on HDAC6 inhibition and assessed the outcome of this regulation on the cellular motility induced by HDAC6.
methodsCell lines (Hela, HEK293 and immortalized mouse embryonic fibroblasts) stably or transiently downregulated for several components of the CTLH complex were employed for the assays used in this study. Interactions of HDAC6, RanBPM and muskelin were assessed by co-immunoprecipitations. Quantifications of western blot analyses were employed to evaluate acetylated α-tubulin levels. Confocal microscopy analyses were used to determine microtubule association of HDAC6 and CTLH complex members. Cell migration was evaluated using wound healing assays.
resultsWe demonstrate that RanBPM-mediated inhibition of HDAC6 is dependent on its association with HDAC6. We show that, while HDAC6 does not require RanBPM to associate with microtubules, RanBPM association with microtubules requires HDAC6. Additionally, we show that Twa1 (Two-hybrid-associated protein 1 with RanBPM) and MAEA (Macrophage Erythroblast Attacher), two CTLH complex members, also associate with α-tubulin and that muskelin, another component of the CTLH complex, is able to associate with HDAC6. Downregulation of CTLH complex members muskelin and Rmnd5A (Required for meiotic nuclear division homolog A) resulted in decreased acetylation of HDAC6 substrate α-tubulin. Finally, we demonstrate that the increased cell migration resulting from downregulation of RanBPM is due to the relief in inhibition of HDAC6 α-tubulin deacetylase activity.
conclusionsOur work shows that RanBPM, together with the CTLH complex, associates with HDAC6 and restricts cell migration through inhibition of HDAC6 activity. This study uncovers a novel function for the CTLH complex and suggests that it could have a tumour suppressive role in restricting HDAC6 oncogenic properties.
