(1) Background: The purpose of this study was to investigate the effects low-dose non-thermal atmospheric plasma (NTP) on proliferation and migration human immortalized keratinocytes (HaCaT cells) its molecular mechanisms. (2) Methods: NTP HaCaT cells were detected by cell viability, wound healing assay, cycle, mitochondrial membrane potential detection, western blot, role reactive oxygen speci...
The Wnt signaling pathways play pivotal roles in carcinogenesis. Modulation of the cell-surface abundance of Wnt receptors is emerging as an important mechanism for regulating sensitivity to Wnt ligands. Endocytosis and degradation of the Wnt receptors Frizzled (Fzd) and lipoprotein-related protein 6 (LRP6) are regulated by the E3 ubiquitin ligases zinc and ring finger 3 (ZNRF3) and ring finger...
Wnt/β-catenin and hedgehog (Hh) signaling are essential for transmitting signals across cell membranes in animal embryos. Early patterning of the principal insect model, Drosophila melanogaster, occurs in the syncytial blastoderm, where diffusion of transcription factors obviates the need for signaling pathways. However, in the cellularizedgrowth zoneof typical short germ insect embryos, signal...
of a dissertation at the University of Miami. Dissertation supervised by Professor Abigail S. Hackam. No. of pages in text. (112) Retinal degeneration is characterized by the irreversible loss of photoreceptors. A key research question is the identification and characterization of photoreceptor protective factors that prevent or delay vision loss. The Wnt pathway is a critical cellular communic...
This study examined the effect of sodium fluoride (NaF) on the Wnt and RhoA signaling pathways in murine ameloblast-lineage cells (ALCs) to better understand the developmental mechanisms of dental fluorosis. Wnt and Rho pathway activities were investigated when ALCs were treated with 1.5 mM NaF, dickkopf-related protein-1 (Dkk-1), secreted frizzled related-protein-2 (sFRP-2), β-catenin siRNA do...

Activation of the Wnt/beta-catenin signaling pathway is a hallmark of a number of solid tumors. We analyzed the regulation of the Wnt/beta-catenin pathway in acute lymphoblastic leukemia (ALL) and its role in the pathogenesis of the disease. We found that expression of the Wnt inhibitors sFRP1, sFRP2, sFRP4, sFRP5, WIF1, Dkk3, and Hdpr1 was down-regulated due to abnormal promoter methylation in...
Activation of the canonical Wnt signaling pathway is an attractive anabolic therapeutic strategy for bone. Emerging data suggest that activation of the Wnt signaling pathway promotes bone mineral accrual in osteoporotic patients. The effect of Wnt stimulation in fracture healing is less clear as Wnt signaling has both stimulatory and inhibitory effects on osteogenesis. Here, we tested the hypot...
