Multicellular network analysis of melanoma heterogeneity by scRNA-seq.
Article in American journal of translational research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveMelanoma neoplasia is a complicated process. Not only melanocytes are involved, stromal cells and immune cells would also regulate cancer development. However, the cell type composition and tumor immune microenvironment of melanoma are poorly understood.
methodHere we report a map of the cellular landscape of human melanoma via analyzing published single-cell RNA sequencing (scRNA-seq) dataset. Transcriptional profiles of 4645 cells obtained from 19 melanoma tissues were dissected.
resultUsing gene expression patterns and flow cytometry, 8 discrete cell populations were identified including endothelial cells (ECs), cancer related fibroblasts (CAFs), macrophages, B cells, T cells (NK cells), memory T cells (MTCs), melanocytes and podocytes. By constructing the cell-specific network (CSN) for each cell population, scRNA-seq data can be used for clustering and pseudo-trajectory analyzing from network perspective. In addition, the differentially expressed genes (DEGs) between malignant and non-malignant melanocytes were identified and analyzed together with clinical data from The Cancer Genome Atlas (TCGA).
conclusionThis study shows a comprehensive view of melanoma at the single cell resolution which outlines the characteristics of resident cells in tumor. Particular, it provides an immune microenvironment map of melanoma.
