HSV-1 inhibits melanogenesis of PIG1 cells through downregulation of VN1R5/ERK pathway.

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
Herpes simplex virus type 1 (HSV-1) is an ubiquitous pathogen that can infect humans through skin or mucous regions. This study was to explore the effects and underlying mechanism of HSV-1 as examined within the human epidermal melanocyte cell line, PIG1. Our results showed that following HSV-1 infection, PIG1 cells shrank and acquired a rounded shape, while the numbers and lengths of their dendrites decreased and melanogenesis was inhibited. Meanwhile, the HSV-1 receptors (nectin-1, herpes virus entry mediator, paired immunoglobulin-like type 2 receptor alpha) and phospho-extracellular signal-regulating kinase (p-ERK) were all substantially decreased, while vomeronasal type-1 receptor 5 (VN1R5) increased. Results of RNA interference and protein inhibitor assays revealed that knockdown of VN1R5 increased the expression of p-ERK and microphthalmia-associated transcription factor (MITF), while an inhibition of ERK decreased VN1R5 expression. Taken together, our study provides the first evidence that HSV-1 can infect human normal melanocytes and inhibit melanogenesis through VN1R5/ERK pathway.
