Article Title: Serelaxin alleviates cardiac fibrosis through inhibiting endothelial-to-mesenchymal transition via RXFP1

doi: 10.7150/thno.38640

Figure Lengend Snippet: Serelaxin promotes the preservation of endothelial cell properties in both in vivo and in vitro by regulating candidate genes. (A) Heat map and (B) scatter plot show the genes with altered mRNA expression level in only TGFβ1-treated (x-axis) or in both TGFβ1- and Serelaxin-treated (y-axis) HCAECs. STEAP1, NOTCH1, JAGGED1, RAC1, DSP, GSC, ERBB3, FZD7, GSK3B and TGFB2 were significantly regulated by Serelaxin treatment, which is shown by separation from dot lines (cut-off by 4 folds). (C-D) qPCR analysis showing the expression of candidate genes, which were identified from qPCR array in TGFβ1- and Serelaxin-treated MCECs. Cells without any treatment were used as control. (E) qPCR analysis of the panel of candidate genes in vivo in sham and AAC-operated mice treated with vehicle or Serelaxin. Serelaxin significantly rescued the effects of AAC on all genes except for Gsc and Steap1. Student t-test was used for single comparison and one-way ANOVA with Bonferroni post-hoc analysis was used for multiple group comparisons.

doi: 10.7150/thno.38640

Figure Lengend Snippet: Serelaxin rescues the Notch1 pathway in AAC-operated hearts. Immunofluorescence staining of (A) Jagged1, (B) Notch1 and (C) NICD in combination with WGA and DAPI in sham and AAC-operated hearts treated with vehicle or Serelaxin. Quantifications showed that protein expressions of (D) Jagged1, (E) Notch1 and (F) NICD were downregulated in AAC-operated hearts and could be restored by Serelaxin. (G) Western blot analysis shows the amount of the soluble form of Jagged1 in the medium of TGFβ1-treated MCECs. Ponceau-S stained membrane picture indicates that an equal amount of total precipitated protein was loaded for both the control and TGFβ1-treated MCECs. Soluble Jagged1 was reduced in TGFβ1-treated MCECs as quantified by densitometry analysis (right panel). Student t-test was used for single comparison and one-way ANOVA with Bonferroni post-hoc analysis was used for multiple group comparisons.

Figure Lengend Snippet: CSCs or non-CSCs were isolated from 231BrM cells, and a limiting dilution analysis was done by intracardially injecting various numbers of cells into nude mice followed by monitoring the incidence of brain metastasis by BLI.

CSCs were prepared from MDA231 and MDA231-IL1β, and 10 5 cells were intracardially injected into nude mice followed by measuring the total photon flux in the brain ex vivo at the end point (left panel). The result of brian metastasis-free survival was shown in the right panel. CSCs were prepared from 231BrM cells and 5 × 10 4 cells were intracardially injected to each group of mice ( n = 12) followed by treatment with Compound E or vehicle only followed by measuring the total photon flux in the brain for 32 days. Proposed model for the growth of breast CSCs in the brain. IL-1β secreted from metastatic CSCs up-regulates JAG1 on the reactivated astrocytes which in turn promote self-renewal of CSCs through JAG1-Notch-HES5 axis. P values were calculated by a two-tailed Student's t test. Proposed model for the growth of breast CSCs in the brain.
