p53-independent association between SV40 large T antigen and the major cytosolic heat shock protein, HSP90.
Article in Oncogene, 2000. 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
The simian double strand DNA tumor virus SV40 encodes the 90-kDa multi-functional protein, large T antigen (LT). LT functions by binding to DNA, as well as to many cellular target proteins such as p53 and retinoblastoma protein (pRB). We report here the identification of a cellular heat shock protein, HSP90, as a previously undescribed LT-associated protein. Immunoprecipitates by anti-HSP90 antibodies from LT-expressing cell lysates contained LT protein, as revealed by Western blotting. Conversely, anti-LT antibody co-immunoprecipitated HSP90. Co-immunoprecipitation of HSP90 and LT was observed even after complete immuno-depletion of p53, indicating that the association of LT with HSP90 is p53-independent. LT-HSP90 complexes can be reconstituted from purified HSP90 and unfolded-LT in vitro in an ATP-independent manner but not from HSP90 and native LT, suggesting that non-mature conformation of LT is required for the efficient association with HSP90. Moreover, geldanamycin, an anti-tumor drug that specifically binds and inhibits HSP90, reduced the intracellular concentration of LT by destabilizing newly synthesized LT. The above results suggest that HSP90 associates with immature forms of LT both in vivo and in vitro, and thus might assist LT in the formation of a functional, mature structure.
