Stereochemistry and position-dependent effects of carcinogens on TATA/TBP binding.
Article in Biophysical journal, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 TATA-box binding protein (TBP) is required by eukaryotic RNA polymerases to bind to the TATA box, an eight-basepair DNA promoter element, to initiate transcription. Carcinogen adducts that bind to the TATA box can hamper this important process. Benzo[a]pyrene (BP) is a representative chemical carcinogen that can be metabolically converted to highly reactive benzo[a]pyrene diol epoxides (BPDE), which in turn can form chemically stereoisomeric BP-DNA adducts. Depending on the TATA-bound adduct's location and stereochemistry, TATA/TBP binding can be decreased or increased. Our previous study interpreted the location-dependent effect in terms of conformational freedom and major-groove space available to BP. Here we further explore specific structural changes of the TATA/TBP complex to help interpret the stereochemical effect in terms of the flexibility of the TATA bases that frame the intercalated adduct. Thermodynamic analyses using molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) yield large standard deviations, which make the computed binding free energies the same within the error bars and point to current limitations of free energy calculations of large and highly charged systems like DNA/protein complexes.
