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

purposeDuplex drugs are promising anticancer agents. After in vivo cleavage into active nucleoside analogues, they exert their anti-tumour activity with reduced toxicity and side effects. Here we evaluated the impact of two duplex drugs on the viability of hepatoblastoma (HB) cells lines and their toxicity against human fibroblasts.

methodsThe duplex drugs 2'-deoxy-5-fluorouridylyl-(3'-5')- 3'-C-ethynylcytidine (5-FdU(3'-5')ECyd) and 3'-C-ethynylcytidinylyl-(5'→1-O)-2-O-octadecyl-sn-glycerylyl-(3'-Ο→5')-2'-deoxy-5-fluorouridine (ECyd-lipid-5-FdU) were analysed in two HB cell lines (HUH6, HepT1) and fibroblasts by MTT assay. The treatment potential was compared to the single substances 2'-deoxy-5-fluorourindine (5-FdU), 3'-C-ethynylycytidine (ECyd) and an equimolar mixture of both. Cell cycle analyses were performed using flow cytometry after 7-AAD staining.

resultsBoth duplex drugs achieve a potent cytotoxic effect at low μM concentrations, which was more pronounced than the mixture of ECyd + 5-FdU. Further, both substances exert toxicity on fibroblasts of tumour samples, with less toxicity in foreskin fibroblasts cultures. Cell cycle analyses revealed a shift towards apoptotic cells for both drugs in HB cells.

conclusion5-FdU(3'-5')ECyd and ECyd-lipid-5-FdU exert a highly potent anti-tumoural effect on HB cells and might therefore be a treatment option in HB. Pharmacological formulations of both duplex drugs have to be evaluated in vivo to reduce possible side effects.
