Abstract Background The HIF-1α/Notch signaling pathway has been shown to regulate proliferation, apoptosis, and metabolism in the intervertebral disc (IVD). The NP is an important structure adjacent to the disc. However, the roles of HIF1α and Notch signaling pathways in NP cells of patients with different Modic changes (MCs) are unclear. The purpose of this research was to assess the expression and association of HIF-1α and components of the Notch pathway in nucleus pulposus (NP) tissue of patients with various MCs. Methods Eighty-five surgical NP tissue samples were obtained from patients undergoing microdiscectomy procedures for the treatment of low back and root pain caused by prolapse of the IVD. The NP tissues were divided into four groups based on the adjacent endplate degeneration: MC I, II, III, and negative MC groups. The expression of HIF-1α and Notch-related components were measured and compared. Results The expression of HIF-1α, Notch1, and Notch2 were gradually increased in the MC I and MC II groups compared with that of the negative MC group. Meanwhile, HIF-1α and Notch-related components were rarely detected in MC III group. Conclusions The expression of HIF-1α/Notch is increased in the NP cells of patients with MC I and MC II. Application of the association between HIF-1α/Notch signaling pathway could be promising target for clinical diagnosis and treatment of disc degeneration in MC patients.

Abstract Background Breast cancer (BC) is one of the commonest female cancers, which is characterized with high incidence. Although treatments have been improved, the prognosis of BC patients in advanced stages remains unsatisfactory. Thus, exploration of the molecular mechanisms underneath BC progression is necessary to find novel therapeutic methods. Frizzled class receptor (FZD2) belongs to Frizzled family, which has been proven to promote cell growth and invasion in various human cancers. The purpose of our study was to detect the functions of FZD2 and explore its mechanism in BC. Methods The level of FZD2 was measured in BC tissues by quantitative realtime polymerase chain reaction (qRT-PCR), western blot, immunohistochemistry (IHC) respectively. Cell Counting Kit-8 (CCK-8), standard colony formation, transwell aasays, wound healing and flow cytometry experiments were adopted separately to test cell viability, invasion, migration, apoptosis and cell cycle distribution. Epithelial-mesenchymal transition (EMT) biomarker were determined by using Immunofluorescence assay. Xenograft tumorigenicity assay was performed to assess the effect of FZD2 on tumor growth in vivo. Results We determined that FZD2 mRNA and protein expression was abundant in BC tissues. Moreover, high level of FZD2 had significant correlation with poor prognosis. In vitro functional assays revealed that silencing of FZD2 had suppressive effects on BC cell growth, migration and invasion. Animal study further demonstrated that FZD2 silencing inhibited BC cell growth in vivo. In addition, FZD2 induced EMT in BC cells in a transforming growth factor (TGF)-β1-dependent manner. Mechanistically, knockdown of FZD2 led to the inactivation of Notch signaling pathway. Conclusion Based on all these data, we concluded that FZD2 facilitates BC progression and promotes TGF-β1-inudced EMT process through activating Notch signaling pathway.

Abstract Background Breast cancer (BC) is one of the commonest female cancers, which is characterized with high incidence. Although treatments have been improved, the prognosis of BC patients in advanced stages remains unsatisfactory. Thus, exploration of the molecular mechanisms underneath BC progression is necessary to find novel therapeutic methods. Frizzled class receptor 2 (FZD2) belongs to Frizzled family, which has been proven to promote cell growth and invasion in various human cancers.
