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

Hepatocellular carcinoma (HCC) is a lethal malignancy with limited treatment options. Sorafenib is the only Food and Drug Administration (FDA)-approved first-line targeted drug for the treatment of advanced HCC. However, its effect on patient survival is limited. Recently, studies have demonstrated that the imbalance between apoptosis and autophagy plays a critical role in chemoresistance, and it is hypothesised that restoring the balance between these processes is a potential treatment strategy for improving chemoresistance in cancer. However, there is currently no evidence supporting this hypothesis. We aimed to investigate if vaccinia-related kinase 2 (VRK2), a serine/threonine protein kinase, confers sorafenib resistance in HCC cells. Here, we found that VRK2 was enriched in sorafenib-resistant HCC cells and patient-derived xenografts. Both in vivo and in vitro evidences showed that VRK2 blunts the efficacy of sorafenib against hepatocellular carcinoma by disturbing the balance between apoptosis and autophagy. Mechanistically, VRK2 promotes the phosphorylation of Bcl-2 by activating JNK1/MAPK8, thereby enhancing the dissociation of Bcl-2 from Beclin-1 and promoting the formation of the Beclin-1-Atg14-Vps34 complex, which facilitates autophagy. Furthermore, VRK2-induced phosphorylation of Bcl-2 promotes the interaction of Bcl-2 with BAX, thereby inhibiting apoptosis. In conclusion, targeting VRK2 for modulation of the balance between autophagy and apoptosis may be a novel strategy for overcoming sorafenib resistance in HCC.
