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

backgroundMantle cell lymphoma (MCL) is an incurable B cell-derived malignant tumor with a median overall survival of 4-5 years. Mer tyrosine kinase (MerTK) has been reported to be aberrantly expressed in leukemia, melanoma, and gastric cancer, and plays a pivotal role in the process of oncogenesis. This study assessed the role of MerTK in MCL for the first time.

methodsImmunohistochemistry and western blot were performed to figure out expression of MerTK in MCL. MerTK inhibition by either shRNA or treatment with UNC2250 (a MerTK-selective small molecular inhibitor) was conducted in MCL cell lines. MCL-cell-derived xenograft models were established to evaluate the anti-tumor effects of UNC2250 in vivo.

resultsMerTK was ectopically expressed in four of six MCL cell lines. Sixty-five of 132 (48.9%) MCL patients showed positive expression of MerTK. MerTK inhibition by either shRNA or treatment with UNC2250 decreased activation of downstream AKT and p38, inhibited proliferation and invasion in MCL cells, and sensitized MCL cells to treatment with vincristine in vitro and doxorubicin in vitro and in vivo. UNC2250 induced G2/M phase arrest and prompted apoptosis in MCL cells, accompanied by increased expression of Bax, cleaved caspase 3 and poly (ADP-ribose) polymerase, and decreased expression of Bcl-2, Mcl-1 and Bcl-xL. Moreover, UNC2250 delayed disease progression in MCL-cell-derived xenograft models.

conclusionsOur data prove that ectopic MerTK may be a novel therapeutic target in MCL, and further pre-clinical or even clinical studies of UNC2250 or new MerTK inhibitors are essential and of great significance.
