(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...

background: hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. on the other hand, mesenchymal stem cells (mscs) are regarded as potent cells with a property of cartilage regeneration. we aimed to optimize marrow-derived msc chondrogenic culture using a small bioactive molecule referred to as bio. methods: mscs from the ma...

Colorectal cancer (CRC) is the third most frequent and second leading cause of cancer-related deaths globally. Evidence shows that over 90% CRC cases are initiated by a deregulated Wingless Integrated Type-1 (WNT)/β-catenin signaling pathway. The WNT/β-catenin pathway also promotes cell proliferation, stemness, metastasis. Therefore, modulators may serve as promising regimens for CRC. This stud...

Wnt signaling has emerged as a central regulator of skeletal modeling and remodeling. Loss- or gain-of-function mutations in two Wnt co-receptors, Lrp5 and (more recently) Lrp6, have drawn attention to the importance of the Wnt pathway in bone biology. This review summarizes our current understanding of how the Wnt pathway operates on bone and the implications this has for skeletal physiology a...

The WNT signal transduction cascade is a main regulator of development throughout the animal kingdom. Wnts are also key drivers of most types of tissue stem cells in adult mammals. Unsurprisingly, mutated Wnt pathway components are causative to multiple growth-related pathologies and to cancer. Here, we describe the core Wnt/β-catenin signaling pathway, how it controls stem cells, and contribut...

Background: Telomerase up-regulation is found in about 90% human cancer specimens and contributes actively to carcinogenesis. Results: β-catenin/TCF4 plays an important role in telomerase activation. Conclusion: hTERT is a direct transcriptional target of the Wnt/β-catenin pathway. Significance: Identifying the function of Wnt/β-catenin pathway in telomerase regulation provides better insight i...

Pancreatic ductal adenocarcinoma (PDA) is an extremely aggressive malignancy, which carries a dismal prognosis. Activating mutations of the Kras gene are common to the vast majority of human PDA. In addition, recent studies have demonstrated that embryonic signaling pathway such as Hedgehog and Notch are inappropriately upregulated in this disease. The role of another embryonic signaling pathwa...

Using yeast-two hybrid screening followed by co-immunoprecipitation assay, we have found that the Lafora disease ubiquitin ligase malin interacts with dishevelled2, a key mediator of Wnt signaling pathway. Overexpression of malin enhances the degradation of dishevelled2 and inhibits Wnt signaling, which is evident from the down-regulation of β-catenin target genes and the decrease in β-catenin-...

Wg/Wnt signals specify cell fates in both invertebrate and vertebrate embryos and maintain stem-cell populations in many adult tissues. Deregulation of the Wnt pathway can transform cells to a proliferative fate, leading to cancer. We have discovered that two Drosophila proteins that are crucial for cytokinesis have a second, largely independent, role in restricting activity of the Wnt pathway....

Mammary glands, like other skin appendages such as hair follicles and teeth, develop from the surface epithelium and underlying mesenchyme; however, the molecular controls of embryonic mammary development are largely unknown. We find that activation of the canonical WNT/beta-catenin signaling pathway in the embryonic mouse mammary region coincides with initiation of mammary morphogenesis, and t...
