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

backgroundResistance to chemotherapy is a major obstacle in the treatment of human hepatocellular carcinoma (HCC). Despite playing an important role in chemoprevention, nuclear factor erythroid 2-related factor 2 (NRF2) also contributes to chemo- and radio-resistance. The current study focusses on camptothecin as a novel NRF2 inhibitor to sensitise HCC to chemotherapy.

methodsThe expression and transcriptional activity of NRF2 in human HCC biopsies and camptothecin-treated culture cells were determined using immunostaining, western blot, reverse-transcription quantitative real-time PCR (RT-qPCR) and luciferase reporter assay. The effect of camptothecin on chemosensitivity of cancer cells was assessed in vitro and in xenografts.

resultsThe expression and transcriptional activity of NRF2 were substantially elevated in HCC biopsies compared with corresponding adjacent tissues, and positively correlated with serum α-fetoprotein, a clinical indicator of pathological progression. In searching chemicals targeting NRF2 for chemotherapy, we discovered that camptothecin is a potent NRF2 inhibitor. Camptothecin markedly suppressed NRF2 expression and transcriptional activity in different types of cancer cells including HepG2, SMMC-7721 and A549. As a result, camptothecin sensitised these cells to chemotherapeutic drugs in vitro and in xenografts.

conclusionsCamptothecin is a novel NRF2 inhibitor that may be repurposed in combination with other chemotherapeutics to enhance their efficacy in treating high NRF2-expressing cancers.
