1 · What the graph read from it

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.

2 · The registry

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 genes encoding ubiquitin-congugating enzyme (Ubc)-like proteins have been isolated from both human and yeast cells. The CROC-1 gene was isolated by its ability to transactivate c- fos expression in cell culture through a tandem repeat enhancer sequence. The yeast MMS2 gene was cloned by its ability to complement the methyl methanesulfonate sensitivity of the mms2-1 mutant and was later shown to be involved in DNA post-replication repair. We report here the identification of a human MMS2 ( hMMS2 ) cDNA encoding a novel human Ubc-like protein. hMMS2 and CROC-1 share >90% amino acid sequence identity, but their DNA probes hybridize to distinct transcripts. hMMS2 and CROC-1 also share approximately 50% identity and 75% similarity with the entire length of yeast Mms2. Unlike CROC-1 , whose transcript appears to be elevated in all tumor cell lines examined, the hMMS2 transcript is only elevated in some tumor cell lines. Collectively, these results indicate that eukaryotic cells may contain a highly conserved family of Ubc-like proteins that play roles in diverse cellular processes, ranging from DNA repair to signal transduction and cell differentiation. The hMMS2 and CROC-1 genes are able to functionally complement the yeast mms2 defects with regard to sensitivity to DNA damaging agents and spontaneous mutagenesis. Conversely, both MMS2 and hMMS2 were able to transactivate a c- fos - CAT reporter gene in Rat-1 cells in a transient co-transfection assay. We propose that either these proteins function in a common cellular process, such as DNA repair, or they exert their diverse biological roles through a similar biochemical interaction relative to ubiquitination.
