Background: Line of HIF-1α / Notch signaling regulate cell proliferation, apoptosis, and metabolism of the intervertebral disc (IVD) and is involved in disc degeneration. The nucleus pulposus (NP) is an important structure adjacent to the IVD. However, the role of HIF-1α / Notch signaling pathway in NP cells obtained from patients with different Modic changes (MC) is still unclear. The purpose of this study was to investigate the role of HIF-1α and components of the Notch pathway in NP obtained from patients with various MC.
Methods: A total of 85 NP tissue samples collected from patients who underwent diskectomy for the treatment of low back pain. NP network were divided into four groups based on the adjacent endplate degeneration, namely, MC I, II, III, and negative MC group. Expression of HIF-1α and Notch-related component is measured and compared.
Results: The expression of HIF-1α, Notch1 and Notch2 gradually increased in the first MC and MC II group than in the negative group MC. HIF-1α and Notch-related components are rarely detected in MC group III. Conclusion: The expression of HIF-1α / Notch increased in cells of patients with NP MC MC I and II. HIF-1α and components related to the potential biomarkers Notch and HIF-1α / Notch signaling pathway may serve as a promising therapeutic target for disc degeneration in patients with MC.
Correlation between the HIF-1α/Notch signaling pathway and Modic changes in nucleus pulposus cells isolated from patients with low back pain
Targeting the Notch signaling pathway and TGF-β to prevent retinal fibrosis in vitro and in vivo
Rationale: Notch and transforming growth factor-β (TGFβ) two signaling pathways that control intracellular mechanisms of fibrosis in general, but if they play a major role in retinal fibrosis is less clear. Here we learn how these two signal pathways regulate cell Müller-dominated retinal fibrosis in vitro and in vivo. Methods: Human cells MIO-M1 Müller and TGFβ1 treated with Notch ligands, either alone or in combination. Western blot was conducted to study the changes protease γ-Secretase, Notch downstream effectors, endogenous TGFβ1, Smad3 phosphorylated (p-Smad3) and the extracellular matrix (ECM) proteins.
We also studied the effects RO4929097, a selective inhibitor of γ-Secretase, the ECM protein expression after ligand stimulation. Müller cell viability and cytotoxicity was studied by AlamarBlue to test the cytotoxicity of lactate. Finally, we studied the changes in Notch and TGFβ signaling and test the effect of an intravitreal injection of Notch pathway inhibitors RO4929097 on retinal fibrosis resulting from sodium iodate (NaIO3) -induced retinal injury in rats.
We also studied the security of RO4929097 intravitreal injection of normal mice. Results: Treatment of Muller cells with protease deregulated Notch ligand and Notch γ-Secretase downstream effector, with an increased expression of endogenous TGFβ1, TGFβ receptor and p-Smad3. TGFβ1 regulated expression of proteins associated with both signal paths in the same way. Notch ligands and TGFβ1 have an additive effect on ECM protein overexpression in Müller cells were inhibited by RO4929097. Notch and TGFβ ligand stimulates proliferation of Müller cells were inhibited by RO4929097 without damaging the cells. NaIO3-induced injury to the retina enabled both Notch and TGFβ signaling pathway in vivo intravitreal injection RO4929097 prevented gliosis Müller cells and inhibit excessive ECM proteins in this murine model.
