Abstract

Slit/Robo signaling was originally identified as a repulsive guidance cue in regulating axon branching and neuronal migration. Hepatic stellate cells (HSCs) are the key fibrogenic cells in the liver, which are migratory when activated, and express neural crest markers. The aim of the present study was to investigate the functional significance of Slit/Robo signaling in liver fibrogenesis and in HSCs. By transcriptomic analysis it was found that axon guidance signaling pathways were significantly upregulated in both diethylnitrosamine (DEN) and thioacetamide (TAA)-induced experimental liver fibrosis. The up-regulation of the ligand Slit2 and membrane receptor Robo2 genes within this pathway was further validated in TAA-induced fibrotic livers. By immunofluorescence staining, Robo2 was localized in fibrotic septa of fibrotic liver and on the surface of HSCs. By Western blot analysis, recombinant Slit2 (rSlit2) was found to promote fibrogenic protein expression in JS1 cells, an immortalized mouse HSC line, while activating PI3K/Akt signaling pathway. This effect was abrogated by LY294002, a PI3K/Akt pathway inhibitor. In addition, rSlit2 stimulation markedly inhibited JS1 cells migration in transwell migration assays, which was abrogated by small interfering RNA (siRNA) knockdown of Robo2 in the cells. The present study provides evidence that Slit2/Robo2 signaling mediates the pathogenesis of hepatic fibrogenesis and regulates HSCs biology, thus providing potential markers for HSCs, and therapeutic and diagnostic target toward liver fibrosis.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 27 April 2018.
All research outputs
#10,266,665
of 12,861,409 outputs
Outputs from Life Sciences
#3,701
of 4,471 outputs
Outputs of similar age
#203,701
of 270,038 outputs
Outputs of similar age from Life Sciences
#30
of 63 outputs
Altmetric has tracked 12,861,409 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,471 research outputs from this source. They receive a mean Attention Score of 3.9. This one is in the 10th percentile – i.e., 10% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 270,038 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
