Screening and analysis of differentially expressed genes of human melanocytes in skin cells mixed culture.
Article in American journal of translational research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThis study aims to screen the key genes and possible signaling pathways involved in the differentiation and proliferation of human melanocytes (MCs) by in vitro culture of mixed skin cells. This will be helpful to further study the mechanisms and treatment strategies of pigment-related diseases such as vitiligo.
methodsMixed skin cells were obtained by digesting and separating normal human foreskin tissues. Ribonucleic acid (RNA) was extracted from sorting cells and high-throughput transcriptome sequencing was performed at different culture time points. Differentially expressed genes (DEGs) were obtained by comparing the expression abundance of genes at different culture time points. Then the key genes and signaling pathways involved in the differentiation and proliferation of MCs were screened and verified by real-time quantitative polymerase chain reaction (qPCR) test.
resultsTwenty one DEGs were finally screened for further qPCR validation, mainly involved in 4 signaling pathways. The expressions of Wnt5A, Wnt5B, FZD2 and FZD3 in Wnt pathway were continuously up-regulated, and that of Wnt4 gene was continuously down-regulated, however, all the above hadn't been verified by qPCR. The expressions of COL5A2, COL6A3, ITGB1, ITGA4, ITGAV, AKT3, PIK3CD, PIK3R1 and PIK3R2 in phosphoinositide 3-kinase (PI3K) pathway were continuously up-regulated, of which PIK3CD, PIK3R2, COL5A2, ITGA4, ITGAV and AKT3 were verified by qPCR. PDGFB and GRB2 gene expressions were down-regulated in platelet-derived growth factor (PDGF) pathway, while PDGFRB was continuously up-regulated, of which PDGFB and PDGFRB were verified. The DHRS3, DHRS9, RDH10 and SDR16C5 genes in retinol metabolic pathway were continuously down-regulated and verified by qPCR.
conclusionWe suggested that Wnt5A gene in Wnt/β-catenin classical pathway, integrin combining with extracellular matrix through PI3K signaling pathway, retinoic acid catabolism-related genes could promote the differentiation and proliferation of MCs; however, PDGFB gene might have a negative regulatory effect on the growth of MCs.
