Expression of RAD51, BRCA1 and P53 does not correlate with cellular radiosensitivity of normal human fibroblasts.
Article in Irish journal of medical science, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsTo evaluate the potential role of key DNA repair proteins in the sensitivity of normal human fibroblasts to ionising radiations.
methodsRadiosensitivity of six human fibroblast strains established from skin biopsies of women who had undergone conservative breast surgery and received a curative breast conserving radiotherapy was measured by colony-formation assay. The expression level of RAD51, BRCA1 and p53 proteins were studied using western blot analysis.
resultsThe six fibroblast strains represent a typical spectrum of normal human radiosensitivity with the surviving fraction measured for a dose of 3.5 Gy (SF3.5) ranging from 0.21 to 0.40. We found that these differences in cell survival did not correlate with the expression of RAD51, BRCA1 nor p53 in the tested normal human fibroblast strains.
conclusionsWe conclude that measurement of protein expression of the three tested genes (RAD51, BRCA1 and p53) did not reflect sensitivity of normal fibroblasts to IR.
