This study investigated whether Bone morphogenetic protein 1 (BMP1) contributes to endometriosis lesion development by examining BMP1-3 expression in a mouse endometriosis model and using anti-BMP1 antibodies. In vivo and in vitro, anti-BMP1 treatment or si-BMP1 suppressed lesion-relevant signaling, including dose-dependent reductions in MMP2, MMP9, TGF-β, IL-17, IL-1β, and collagen genes (Col1a1/Col1a2) and suppression of the TGF-β/PI3K/Akt pathway. A major limitation is that the work relies on an animal model and cell assays rather than direct demonstration in human endometriosis tissue. This paper is centrally about endometriosis — it tests BMP1 inhibition with anti-BMP1 antibodies and si-BMP1 to attenuate endometriosis lesions and linked inflammatory/fibrotic and PI3K/Akt signaling changes.

Abstract

PURPOSE: To investigate the potential role of Bone morphogenetic protein 1 (BMP1) in endometriosis lesions. METHODS: Endometriosis model in mice was established. The expression of BMP1-3 expression in mice of endometriosis lesions was evaluated. The effect of the treatment with anti-BMP1 antibodies on the expression of MMP2, MMP9, TGF-β, IL-17, IL-1β, Col1a1 and Col1a2 levels in mice was evaluated. In endometriosis cell model, the expression of IL-17, IL-1β, MMP2 and MMP9 levels and MIF, YWHAZ, β-catenin and CAP39 mRNA levels was also detected. RESULTS: The expression of BMP1-3 expression was upregulated in mice of endometriosis lesions (p < 0.01). Treatment with anti-BMP1 antibodies dose-dependently reduced MMP2, MMP9, TGF-β, IL-17, IL-1β, Col1a1 and Col1a2 levels in mice (p < 0.01). Treatment with anti-BMP1 antibodies suppressed TGF-β/PI3K/Akt signaling pathway. In vitro cell, si-BMP1 suppressed TGF-β/PI3K/Akt signaling pathway. CONCLUSION: The data support the hypothesis that the inhibition of BMP1 is involved in the pathogenesis of endometriosis lesions.

Abstract

Purpose To investigate the potential role of Bone morphogenetic protein 1 (BMP1) in endometriosis lesions.

Methods

Endometriosis model in mice was established. The expression of BMP1-3 expression in mice of endometriosis lesions was evaluated. The effect of the treatment with anti-BMP1 antibodies on the expression of MMP2, MMP9, TGF-β, IL-17, IL-1β, Col1a1 and Col1a2 levels in mice was evaluated. In endometriosis cell model, the expression of IL-17, IL-1β, MMP2 and MMP9 levels and MIF, YWHAZ, β-catenin and CAP39 mRNA levels was also detected.

Results

The expression of BMP1-3 expression was upregulated in mice of endometriosis lesions (p < 0.01). Treatment with anti-BMP1 antibodies dose-dependently reduced MMP2, MMP9, TGF-β, IL-17, IL-1β, Col1a1 and Col1a2 levels in mice (p < 0.01). Treatment with anti-BMP1 antibodies suppressed TGF-β/PI3K/Akt signaling pathway. In vitro cell, si-BMP1 suppressed TGF-β/PI3K/Akt signaling pathway.

Conclusion

The data support the hypothesis that the inhibition of BMP1 is involved in the pathogenesis of endometriosis lesions. Similar content being viewed by others
