Dynein Light-Chain Dynlrb2 Is Essential for Murine Leukemia Virus Traffic and Nuclear Entry.
Article in Journal of virology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Murine leukemia virus (MLV) requires the infected cell to divide to access the nucleus to integrate into the host genome. It has been determined that MLV uses the microtubule and actin network to reach the nucleus at the early stages of infection. Several studies have shown that viruses use the dynein motor protein associated with microtubules for their displacement. We have previously reported that dynein light-chain roadblock type 2 (Dynlrb2) knockdown significantly decreases MLV infection compared to nonsilenced cells, suggesting a functional association between this dynein light chain and MLV preintegration complex (PIC). In this study, we aimed to determine if the dynein complex Dynlrb2 subunit plays an essential role in the retrograde transport of MLV. For this, an MLV mutant containing the green fluorescent protein (GFP) fused to the viral protein p12 was used to assay the PIC localization and speed in cells in which the expression of Dynlrb2 was modulated. We found a significant decrease in the arrival of MLV PIC to the nucleus and a reduced net speed of MLV PICs when Dynlrb2 was knocked down. In contrast, an increase in nuclear localization was observed when Dynlrb2 was overexpressed. Our results suggest that Dynlrb2 plays an essential role in MLV retrograde transport.
