Background: Multiple studies have examined the potential of growth factors (GF) to enable mesenchymal stromal cells (MSC) nucleus pulposus (NP) cell-like cell differentiation. Here we screened a wide range GF and combinations for supporting NP Methods: Human MSC were stimulated using 86 different TGF-β1, -2, -3, GDF5, -6, Wnt3a, -5a, -11, Shh. Differentiation potency was assessed by alcian blue...

background: this research studies the effects of activation and inhibition of wnt3a signaling pathway in buffalo (bubalus bubalis) embryonic stem (es) cell-like cells. materials and methods: to carry on this experimental study, the effects of activation and inhibition of wnt3a signaling in buffalo es cell-like cells were examined using bio (0.5 mm) combined with wnt3a (200 ng/ml), as an activat...

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...

Invasion and metastasis are the primary causes of mortality from hepatocellular carcinoma (HCC). Effective inhibition against participants in the tumourigenesis and metastasis process is critical for treatment of HCC. Wnt3a is involved in the development and metastasis of many malignant tumours. However, the specific mechanisms of Wnt3a-mediated cell proliferation, invasion and metastasis in HC...

The dynamic interaction between positive and negative signals is necessary for remodeling of postsynaptic structures at the neuromuscular junction. Here we report that Wnt3a negatively regulates acetylcholine receptor (AChR) clustering by repressing the expression of Rapsyn, an AChR-associated protein essential for AChR clustering. In cultured myotubes, treatment with Wnt3a or overexpression of...

The Wnt signaling pathway plays a critical role in embryogenesis and tumorigenesis. However, biological roles of Wnt growth factors have not been fully characterized in prostate development and the pathogenesis of prostate cancer. In this study, we used Wnt3a-conditioned medium (Wnt3a-CM) and purified Wnt3a proteins to investigate whether there is a direct effect of Wnt3a on androgen receptor (...

BACKGROUND Wnt/beta-catenin signaling is involved in the growth of various types of cancer cells. Wnt3A has been reported to promote the self-renewal of hematopoietic stem cells. MATERIALS AND METHODS The effects of recombinant Wnt3A protein on the in vitro growth of four acute myeloid leukemia (AML) and four acute T-lymphoblastic leukemia (T-ALL) cell lines was examined. RESULTS Wnt3A stim...
