Temporal gating of nuclear import: How Merkel cell polyomavirus exploits the cell cycle for nuclear entry.
Article in PLoS pathogens, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
Merkel cell polyomavirus (MCPyV) is a small, DNA tumor virus that is causally linked to an aggressive form of human skin cancer called Merkel cell carcinoma. MCPyV is the only polyomavirus definitively shown to cause cancer in humans, yet little is known about how it establishes infection in target cells. In this study, we report an unconventional mechanism by which MCPyV enters the host cell nucleus, where viral genome replication occurs. We demonstrate that, unlike other known polyomaviruses, MCPyV does not require the nuclear pore complex during entry. Instead, it takes advantage of cell cycle-dependent nuclear envelope breakdown to deliver its genetic material into the nucleus. We further show that the VP1 major capsid protein is sufficient to facilitate this process. Overall, our findings reveal a novel mechanism of polyomavirus nuclear entry and provide insight into the diverse mechanisms that these viruses use to cause infection.
