Human hRad1 but not hRad9 protects hHus1 from ubiquitin-proteasomal degradation.
Article in Oncogene, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Three of the Rad family proteins, Rad9, Rad1, and Hus1, can interact with each other and form a heterotrimeric complex that is thought to play a role in the sensing step of the DNA integrity checkpoint pathways, but the nature of the Rad9-Rad1-Hus1 complex assembly remains enigmatic. Here, we demonstrate that the human hRad1 protein plays a significant role as molecular chaperone in the process of the hRad9-hRad1-hHus1 heterotrimeric complex formation. In contrast to hRad1, hHus1 is an unstable protein that is actively degraded via the ubiquitin-proteasome pathway. We show that treating cells with proteasome-specific inhibitors stabilizes hHus1 expression. Moreover, hRad1 can associate with hHus1 in the absence of hRad9 and protect hHus1 from ubiquitination and degradation in the cytoplasm. Importantly, genotoxic stress induces hRad1 expression and stabilizes the hHus1 protein. Taken together, these findings suggest a novel role of hRad1 as a potential intrinsic chaperone in the stabilization of hHus1 for the hRad9-hRad1-hHus1 checkpoint complex formation.
