Key Points GPIb-IX signaling cooperates with PAR signaling to promote platelet response to low concentrations of thrombin, which are important in vivo. Thrombin induces a GPIb-IX–specific signaling pathway that requires the cytoplasmic domain of GPIbα, 14-3-3 protein, Rac1, and LIMK1.

Understanding living systems requires an in depth knowledge of the signaling networks that drive cellular homeostasis, regulate intercellular communication and contribute to cell fates during development. Several resources exist to provide high-throughput datasets or manually curated interaction information from human or invertebrate model organisms. We previously developed SignaLink, a uniformly curated, multi-layered signaling resource containing information for human and for the model organisms nematode Caenorhabditis elegans and fruit fly Drosophila melanogaster. Until now, the use of the SignaLink database for zebrafish pathway analysis was limited. To overcome this limitation we created SignaFish (http://signafish.org), a fish-specific signaling resource, built using the concept of SignaLink. SignaFish contains more than 200 curation based signaling interactions, 132 further interactions listed in other resources, and it also lists potential miRNA based regulatory connections for 7 major signaling pathways. From the SignaFish website, users can reach other web resources, such as ZFIN. SignaFish provides signaling or signaling-related interactions that can be examined for each gene, or downloaded for each signaling pathway. We believe that the SignaFish resource will serve as a novel navigating point for experimental design and evaluation for the zebrafish community and for researchers focusing on non-model fish species, such as cyclids.

Abstract BACKGROUNDMesangial proliferative glomerulonephritis is characterized by the proliferation of mesangial cells (MCs). Endothelial cells (ECs) are affected by signals from MCs, resulting in capillary proliferation, but the specific signaling pathway associated with this activity remains unclear.RESULTSIn this study, the expression of PCNA, RECA-1 and CD34 in the glomeruli increased on the 7th day after anti-Thy-1 nephritis establishment, indicating the occurrence of ECs proliferation. After coculturing MCs and ECs in vitro, we observed that activated MCs could promote ECs proliferation, migration and α-SMA expression. Moreover, activated ECs had the same effects on MCs. RT-qPCR showed that activated MCs could increasingly secrete VEGFA, and Angpt2 expression in VEGFA-activated ECs was enhanced. Considering that Angpt2-mediated inhibition of ECs surface receptor Tie2 phosphorylation causes ECs proliferation, we hypothesized that VEGFA/VEGFR2 and Angpt2/Tie2 signaling is involved in the interaction between MCs and ECs. Our results showed that blocking VEGFA or adding the Angpt2 antagonist Angpt1 to the coculture system decreased the number of EdU-positive cells，Angpt2，p-VEGFR2 and p-MAPK expression, but increased p-Tie2 in ECs. To determine whether Angpt1 could effectively alleviate the pathological changes of anti-Thy-1 nephritis, we performed Vasculotide (Angpt1 mimic peptide) treatment assays in vivo. The results confirmed that the addition of Vasculotide could effectively reduce PCNA, RECA-1 and α-SMA expression and promote p-Tie2.CONCLUSIONIn summary, the study showed that the VEGFA/VEGFR2 and Angpt2/Tie2 signaling pathway mediate interactions between MCs and ECs, providing an important theoretical basis for the treatment of mesangial proliferative glomerulonephritis.
