SERPINH1 enhances the malignancy of osteosarcoma via PI3K-Akt signaling pathway

Background: Serpin Family H Member 1 (SERPINH1) may be involved in the regulation of occurrence and development of tumors. However, the role and mechanism of SERPINH1 in osteosarcoma remain poorly un-derstood. The aim of this study is to investigate the expression and role of SRPINH1 in osteosarcoma and to elucidate its underlying mechanisms.Methods: First, we examined the expression of SERPINH1 in osteosarcoma and analyzed publicly available datasets to investigate whether SERPINH1 expression was associated with the prognosis of osteosarcoma. Then we constructed SERPINH1 overexpression and knockdown systems in osteosarcoma cells, and examined the proliferation, migration and invasion ability of osteosarcoma cells after SERPINH1 expression changes using CCK-8 assay, wound healing assay and transwell invasion assay. In addition, we constructed a subcutaneous xenograft tumor model to study the function of SERPINH1 in vivo. We also examined the downstream pathways of SERPINH1 by functional analysis and performed subsequent validation.Results: SERPINH1 was upregulated and associated with poor survival in patients with osteosarcoma. SERPINH1 promoted the proliferation, migration and invasion of osteosarcoma cells and promotes the growth of osteo-sarcoma in vivo by activating the PI3K-Akt signaling pathway.Conclusion: SERPINH1 partakes in the biological process of osteosarcoma as a tumor promotor and may be an emerging biomarker in osteosarcoma.
