1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND &

objectivesDerivatives of isatin are known to have cytotoxicity against human carcinoma cell lines. This compound therefore, has a potential to be used as a chemotherapeutic agent against cancer. This study was done to investigate the antioxidant and anticancer activities of isatin, extracted from flower of a folklore medicinal plant Couroupita guianensis against human promylocytic leukemia (HL60) cells.

methodsActive fractions demonstrating anticancer and antioxidant activities were isolated from the extracts of shade-dried flowers of C. guianensis by bioassay guided fractionation. The free radical scavenging activity was determined using lipid peroxidation assay. Cytotoxicity against human promylocytic leukemia HL60 cells was determined by MTT assay. Apoptotic activity was analyzed by DNA fragmentation and flowcytometry.

resultsIsatin isolated from the active fraction showed antioxidant activity with the EC(50) value of 72.80 μg/ml. It also exhibited cytotoxicity against human promylocytic leukemia HL60 cells in dose-dependant manner with the CC(50) value of 2.94 μg/ml. The isatin-treated cells underwent apoptosis and DNA fragmentation. Apoptosis was confirmed by the FACS analysis using FITC-annexin V markers. INTERPRETATION &

conclusionsIsatin showed antioxidant activity and was cytotoxic to the HL60 cells due to induction of apoptosis. The isatin can be further evaluated to be used as a prophylactic agent to prevent the free radical-induced cancer and as a chemotherapeutic agent to kill the cancer cells.
