In vitro long-term treatment with MAPK inhibitors induces melanoma cells with resistance plasticity to inhibitors while retaining sensitivity to CD8 T cells.

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.
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
The development of BRAF V600 and MEK inhibitors constitutes a breakthrough in the treatment of patients with BRAF-mutated metastatic melanoma. However, although there is an increase in overall survival, these patients generally confront recurrence, and several resistance mechanisms have already been described. In the present study we describe a different resistance mechanism. After several weeks of long‑term in vitro treatment of two different V600E BRAF‑mutated melanoma cell lines with MARK inhibitors, PLX4032 and/or GDC-0973, the majority of the cells died whereas some remained viable and quiescent (SUR). Markedly, discontinuing treatment of SUR cells with MAPK inhibitors allowed the population to regrow and these cells retained drug sensitivity equal to that of the parental cells. SUR cells had increased expression levels of CD271 and ABCB5 and presented senescence-associated characteristics. Notably, SUR cells were efficiently lysed by cytotoxic T lymphocytes recognizing MART-1 and gp100 melanoma differentiation antigens. We propose quiescent plasticity as a mechanism of resistance to BRAF and MEK inhibitors while retaining sensitivity to immune effectors.
