BACKGROUND: We previously reported that Wnt5a/CaMKIIδ (calcium/calmodulin-dependent protein kinase II delta) pathway was involved in the embryonic tongue deformity induced by excess retinoic acid (RA). Our latest study found that the expression of miR-31-5p, which was predicted to target the 3'UTR of CamkIIδ, was raised in the RA-treated embryonic tongue. Thus, we hypothesized that the excess RA regulated Wnt5a/CaMKIIδ pathway through miR-31-5p in embryonic tongue. METHODS: C2C12 myoblast line was employed as an in vitro model to examine the suppression of miR-31-5p on CamkIIδ expression, through which RA impaired the myoblast proliferation and differentiation in embryonic tongue...

To investigate the effects and the possible underlying mechanisms of nicotine stimulation on tongue squamous cell carcinoma (TSCC) progression, a TSCC cell line Cal27 and 34 samples of paraffin-embedded TSCC were examined. Immunofluorescence, western blot analysis, and TOP/FOP flash, CCK-8, wound healing and Transwell invasion assays were used to evaluate Cal27 in response to nicotine stimulation. We also investigated expression levels of related proteins of Wnt/β-catenin and Wnt/PCP pathways in paraffin-embedded TSCC samples with or without a history of smoking by immunohistochemistry...

SOX family proteins SOX2 and SOX18 have been reported as being essential in determining hair follicle type; however, the role they play during development remains unclear. Here, we demonstrate that Sox18 regulates the normal differentiation of the dermal papilla of all hair types. In guard (primary) hair dermal condensate (DC) cells, we identified transient Sox18 in addition to SOX2 expression at E14.5, which allowed fate tracing of primary DC cells until birth. Similarly, expression of Sox18 was detected in the DC cells of secondary hairs at E16...

Wnt5a is involved in activating several noncanonical Wnt signaling pathways, which can inhibit or activate canonical Wnt/β-catenin signaling pathway in a receptor context-dependent manner. Wnt5a signaling is critical for regulating normal developmental processes, including stem cell self-renewal, proliferation, differentiation, migration, adhesion, and polarity. Moreover, the aberrant activation or inhibition of Wnt5a signaling is emerging as an important event in cancer progression, exerting both oncogenic and tumor suppressive effects...

Here we investigated the impact of WNT5A signaling on aerobic glycolysis and evaluated its effects on breast cancer cell migration/invasion. WNT5A signaling reduced migration and lactate production and caused selective down-regulation of the glycolytic enzyme phosphofructokinase platelet-type (PFKP). These events occurred in parallel with a WNT5A-induced inhibition of β-catenin signaling. Support for essential involvement of β-catenin and PFKP in lactate production and migration/invasion was obtained by siRNA knockdown of their expression...

Chondrosarcoma (CS) is a rare cancer, but it is the second most common primary malignant bone tumor and highly resistant to conventional chemotherapy and radiotherapy. Aberrant DNA methylation in the promoter CpG island of Wnt inhibitory factor 1 (WIF1) has been observed in different cancers. However, no studies have shown the relationship between WIF1 methylation and CS. In this study, we found promoter methylated WIF1 in both CS cell lines (CS-1 and SW1353) and tumor tissues. Western blot analysis confirmed loss WIF1 expression and activation of Wnt pathway proteins (Wnt5a/b, LRP6, and Dvl2)...

The Ror-family of receptor tyrosine kinases (RTKs) are involved critically in tissue-genesis and organo-genesis during development. In mammals, Ror1 and Ror2, members of the Ror-family RTKs, have been shown to mediate cell polarity, migration, proliferation, and differentiation through the activation of non-canonical Wnt signaling by acting as receptors or co-receptors for Wnt5a. Nematodes bearing mutations within the cam-1 gene, encoding a Ror2 ortholog, exhibit defects in various developmental processes of the nervous system, including neuronal cell migration, polarization, axonal extension, and synaptic transmission...

The mesenchymal stem cell (MSC) shows potential in degenerative disc disease (DDD) treatment. However, little is known about the function of heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) in modulating the chondrogenic differentiation of MSCs. This study aimed to investigate the role of hnRNPA1 in the chondrogenic differentiation of MSCs and potential mechanisms. Mouse MSCs C3H10 and chondrogenic ATDC5 cells were used to quantify hnRNPA1 expression. The hnRNPA1 overexpression vectors were transfected into C3H10 cells, cell viability and chondrogenic factors expressions were assessed by MTT assay, qPCR and Western blot, respectively...

CYR61-CTGF-NOV (CCN)1 is a dynamically expressed extracellular matrix (ECM) protein with critical functions in cardiovascular development and tissue repair. Angiogenic endothelial cells (ECs) are a major cellular source of CCN1 which, once secreted, associates with the ECM and the cell surface and tightly controls the bidirectional flow of information between cells and the surrounding matrix. Endothelium-specific CCN1 deletion in mice using a cre/lox strategy induces EC hyperplasia and causes blood vessels to coalesce into large flat hyperplastic sinuses with no distinctive hierarchical organization...

ROR1 is a conserved, oncoembryonic surface-antigen expressed in chronic lymphocytic leukemia (CLL). We found that ROR1 associates with Hematopoietic-lineage-cell-Specific protein 1 (HS1) in freshly-isolated CLL cells or in CLL cells cultured with exogenous Wnt5a. Wnt5a also induced HS1 tyrosine phosphorylation, recruitment of ARHGEF1, activation of RhoA, and enhanced chemokine-directed migration; such effects could be inhibited by cirmtuzumab, a humanized anti-ROR1 mAb. We generated truncated forms of ROR1 and found its extra-cellular cysteine-rich domain or kringle domain was necessary for Wnt5a-induced HS1 phosphorylation...

Wnt5a can activate Rho GTPases in chronic lymphocytic leukemia cells by inducing the recruitment of ARHGEF2 to ROR1. Mass spectrometry on immune-precipitates of Wnt5a-activated ROR1 identified 14-3-3ζ, which was confirmed by co-immunoprecipitation. The capacity of Wnt5a to induce ROR1 to complex with 14-3-3ζ could be blocked in CLL cells treated with cirmtuzumab, a humanized mAb targeting ROR1. Silencing 14-3-3ζ via siRNA impaired the capacity of Wnt5a to: (1) induce recruitment of ARHGEF2 to ROR1, (2) enhance in vitro exchange activity of ARHGEF2, and (3) induce activation of RhoA and Rac1 in CLL cells...

Human bone marrow stromal cells (hBMSCs) may contribute to the growth of tyrosine kinase inhibitor (TKI)-resistant chronic myelogenous leukemia (CML). However, there are certain differences in biology between CML and Philadelphia-positive acute lymphoblastic leukemia (Ph(+) ALL). Little is known about the role and mechanism of hBMSCs on the growth of TKI-resistant Ph(+) ALL. The current study co-cultured hBMSCs with the TKI-resistant SUP-B15. Next, the proliferation of SUP-B15 was detected using a Cell Counting Kit-8...

Bladder cancer is the fourth most common cancer in men and the most common malignancy of the urinary tract. Bladder cancers detected at an early stage have a very high five-year survival rate, but when detected after local metastasis the rate is only about 50%. Our group recently reported a positive correlation between the expression of Wnt5a, a member of the Wnt proteins family, and histopathological grade and stage of urothelial carcinoma (UC). The objective of this study was to analyze UC cases reported in Athens, Ohio and investigate the major components of Wnt5a / planar cell polarity (PCP) signaling pathway in UC human tissue samples and UC cell lines...
