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

backgroundLong non-coding RNAs (lncRNA) have an essential role in progression and chemoresistance of hepatocellular carcinoma (HCC). In-depth study of specific regulatory mechanisms is of great value in providing potential therapeutic targets. The present study aimed to explore the regulatory functions and mechanisms of lncRNA TINCR in HCC progression and oxaliplatin response.

methodsThe expression of TINCR in HCC tissues and cell lines was detected by quantitative reverse transcription PCR (qRT-PCR). Cell proliferation, migration, invasion, and chemosensitivity were evaluated by cell counting kit 8 (CCK8), colony formation, transwell, and apoptosis assays. Luciferase reporter assays and RNA pulldown were used to identify the interaction between TINCR and ST6 beta-galactoside alpha-2,6-sialyltransferase 1 (ST6GAL1) via miR-195-3p. The corresponding functions were verified in the complementation test and in vivo animal experiment.

resultsTINCR was upregulated in HCC and associated with poor patient prognosis. Silencing TINCR inhibited HCC proliferation, migration, invasion, and oxaliplatin resistance while overexpressing TINCR showed opposite above-mentioned functions. Mechanistically, TINCR acted as a competing endogenous (ceRNA) to sponge miR-195-3p, relieving its repression on ST6GAL1, and activated nuclear factor kappa B (NF-κB) signaling. The mouse xenograft experiment further verified that knockdown TINCR attenuated tumor progression and oxaliplatin resistance in vivo.

conclusionsOur finding indicated that there existed a TINCR/miR-195-3p/ST6GAL1/NF-κB signaling regulatory axis that regulated tumor progression and oxaliplatin resistance, which might be exploited for anticancer therapy in HCC.
