Objective: To investigate the influence of Notch signaling on osteoprotegerin(OPG)expression in a human oral squamous cell carcinoma cell ***: Activation of Notch signaling was performed by seeding cells on Jagged1 immobilized surfaces. In other experiments, a g-secretase inhibitor was added to the culture medium to inhibit intracellular Notch signaling. OPG m RNA and protein were determined by real-time PCR and ELISA, respectively. Finally, publicly available microarray database analysis was performed using connection up- or down-regulation expression analysis of microarrays ***: Jagged1-treatment of HSC-4 cells enhanced HES1 and HEY1 m RNA expression, confirming the intracellular activation of Notch signaling. OPG m RNA and protein levels were significantly suppressed upon Jagged1 treatment. Correspondingly, HSC-4 cells treated with a g-secretase inhibitor resulted in a significant reduction of HES1 and HEY1 m RNA levels, and a marked increase in OPG protein expression was *** results implied that Notch signaling regulated OPG expression in HSC-4 ***, Jagged1 did not alter OPG expression in another human oral squamous cell carcinoma cell line(HSC-5) or a human head and neck squamous cell carcinoma cell line(HN22).Conclusions: Notch signaling regulated OPG expression in an HSC-4 cell line and this mechanism could be cell line specific.

Objective: To investigate the effect of Tinospora crispa(T. crispa) extract on matrix metalloproteinase 13(MMP-13) expression and cell migration. Methods: The cytotoxicity of T. crispa extract was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay on head and neck squamous cell carcinoma(HNSCC) cell lines. The effect on expression of MMP-13 was analysed by RT-PCR and ELISA. The migration was assessed by wound healing assay. Results: MMP-13 m RNA was highly expressed in the metastatic human HNSCC cell lines, HN22 and HSC-3. T. crispa extract at a concentration of 100.0 μg/m L caused about 50% reduction of cell survival. T. crispa extract at a non-toxic concentration of 12.5, 25.0 and 50.0 μg/m L signii cantly suppressed MMP-13 m RNA expression and secreted MMP-13 in both HN22 and HSC-3. The expression of tissue inhibitors of metalloprotease by HSC-3 cells was attenuated by 25.0 and 50.0 μg/m L of T. crispa extract. Addition of the extract to cells in a wound healing assay showed inhibition of cell migration by HN22 cells. Conclusions: These data suggest that T. crispa could be considered as a potential therapeutic drug to prevent metastasis of HNSCC.

New insights on the role of chondroitin sulfate proteoglycans in neural stem cell–mediated repair in spinal cord injury

Extensive neurodegeneration is a hallmark of traumatic spinal cord injury (SCI) that underlies permanent sensorimotor and autonomic impairments (Alizadeh et al.,2019).Following the primary impact,the spinal cord undergoes a cascade of secondary injury mechanisms that are driven by disruption of the blood-spinal cord ba rrier,vascula r inju ry,glial reactivity,neu roinfla mmation,oxidative stress,lipid peroxidation,and glutamate excitotoxicity that culminate in neuronal and oligodendroglial cell death,demyelination,and axonal damage(Alizadeh et al.,2019).To achieve a meaningful functional recovery after SCI,regeneration of new neurons and oligodendrocytes and their successful growth and integration within the neural network are critical steps for reconstructing the damaged spinal cord tissue (Fischer et al.,2020).

TGF-β/BMP signaling and other molecular events: regulation of osteoblastogenesis and bone formation

引用

Bone research 2015年第1期3卷 11-30页

Transforming growth factor-beta（TGF-β）/bone morphogenetic protein（BMP） plays a fundamental role in the regulation of bone organogenesis through the activation of receptor serine/threonine kinases. Perturbations of TGF-β/BMP activity are almost invariably linked to a wide variety of clinical outcomes, i.e., skeletal, extra skeletal anomalies, autoimmune, cancer, and cardiovascular diseases. Phosphorylation of TGF-β（I/II） or BMP receptors activates intracellular downstream Smads, the transducer of TGF-β/BMP signals. This signaling is modulated by various factors and pathways, including transcription factor Runx2. The signaling network in skeletal development and bone formation is overwhelmingly complex and highly time and space ***, positive, negative, or synergistic effects are observed when TGF-β/BMP interacts with the pathways of MAPK, Wnt, Hedgehog（Hh）, Notch, Akt/m TOR, and mi RNA to regulate the effects of BMP-induced signaling in bone dynamics. Accumulating evidence indicates that Runx2 is the key integrator, whereas Hh is a possible modulator, mi RNAs are regulators, and b-catenin is a mediator/regulator within the extensive intracellular network. This review focuses on the activation of BMP signaling and interaction with other regulatory components and pathways highlighting the molecular mechanisms regarding TGF-β/BMP function and regulation that could allow understanding the complexity of bone tissue dynamics.
