Induction of erythroid differentiation and increased globin mRNA production with furocoumarins and their photoproducts.

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
Differentiation-therapy is an important approach in the treatment of cancer, as in the case of erythroid induction in chronic myelogenous leukemia. Moreover, an important therapeutic strategy for treating beta-thalassemia and sickle-cell anemia could be the use of drugs able to induce erythroid differentiation and fetal hemoglobin (HbF) accumulation: in fact, the increased production of this type of hemoglobin can reduce the clinical symptoms and the frequency of transfusions. An important class of erythroid differentiating compounds and HbF inducers is composed by DNA-binding chemotherapeutics: however, they are not used in most instances considering their possible devastating side effects. In this contest, we approached the study of erythrodifferentiating properties of furocoumarins. In fact, upon UV-A irradiation, they are able to covalently bind DNA. Thus, the erythrodifferentiation activity of some linear and angular furocoumarins was evaluated in the experimental K562 cellular model system. Quantitative real-time reverse transcription polymerase-chain reaction assay was employed to evaluate the accumulation of different globin mRNAs. The results demonstrated that both linear and angular furocoumarins are strong inducers of erythroid differentiation of K562 cells. From a preliminary screening, we selected the most active compounds and investigated the role of DNA photodamage in their erythroid inducing activity and mechanism of action. Moreover, some cytofluorimetric experiments were carried out to better study cell cycle modifications and the mitochondrial involvement. A further development of the work was carried out studying the erythroid differentiation of photolysis products of these molecules. 5,5'-Dimethylpsoralen photoproducts induced an important increase in γ-globin gene transcription in K562 cells.
