Modulation of reactive oxygen levels and gene expression in sensitive and resistant tumoral cells by C-phyocyanin.
Article in Molecular biology reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
In this work we investigated the possible cellular changes induced by C-phycocyanin (C-PC) in erythroleukemic cells with (K562-Lucena and FEPS) and without (K562) the multidrug resistance (MDR) phenotype. The reactive oxygen levels (ROS) (evaluated by fluorimetry) were increased relative to the control in K562 and K562-Lucena cells treated with 100 µg/mL and were not increased in FEPS cells. The expression of the following genes related to resistance was evaluated by real-time PCR: COX2, ALOX5, ABCB1 and ABCC1. Treatment with 100 µg/mL of C-PC increased COX2 and ABCB1 expression in K562-Lucena cells and reduced expression of ALOX5 in K562-Lucena and FEPS cells. ROS levels appear to be involved in biological responses to C-PC in K562 and K562-Lucena cells, although expression of the genes studied here was only modified by C-PC in the K562-Lucena cell line. Thus, it is possible to suggest that C-PC modulates the expression of COX2 and ABCB1 for the K562-Lucena in a ROS-dependent manner and the expression of ALOX5 for the FEPS in a ROS-independent manner; however, more studies are needed to elucidate these mechanisms.
