Wnt signaling is an evolutionarily conserved signaling route required for development and homeostasis. While canonical, β-catenin-dependent Wnt signaling is well studied and has been linked to many forms of cancer, much less is known about the role of non-canonical, β-catenin-independent Wnt signaling. Here, we aimed at identifying a β-catenin-independent Wnt target gene signature in order to understand the functional significance of non-canonical signaling in colon cancer cells. Gene expression profiling was performed after silencing of key components of Wnt signaling pathway and an iterative signature algorithm was applied to predict pathway-dependent gene signatures...

OBJECTIVE: Elevated expression of the ROR1 and ROR2 Wnt receptors has been noted in both the tumour and stromal compartments of ovarian cancer patient tissue samples. In vitro studies have suggested these receptors play a role in ovarian cancer metastasis. However, these previous studies have utilised simple 2D in vitro models to investigate cancer cell growth and migration, which does not allow investigation of stromal involvement in Wnt driven metastasis. AIM: To investigate targeting ROR1 and ROR2 using a primary co-culture 3D model of epithelial ovarian cancer dissemination to the omentum...

As well-characterized ligands involved in neurogenesis, Wnts are emerging as promising targets in pain pathogenesis. Our previous pilot study showed that intrathecal inhibition of Wnt5a, but not Wnts, relieves chronic post-thoracotomy pain (CPTP) in rats. In the present study, we aimed to further explore the regulatory mechanism of Wnt5a in CPTP development. Increased protein levels of Wnt5a, transmembrane receptor Ror2, and activated non-canonical Wnt pathway members were found in the thoracic dorsal root ganglions from postoperative day (POD) 7 to POD 21...

Schwann cells play a critical role in peripheral nerve regeneration through dedifferentiation and proliferation. In a previous study, we performed microarray analysis of the sciatic nerve after injury. Accordingly, we predicted that long non-coding RNA NONMMUG014387 may promote Schwann cell proliferation after peripheral nerve injury, as bioinformatic analysis revealed that the target gene of NONMMUG014387 was collagen triple helix repeat containing 1 (Cthrc1). Cthrc1 may promote cell proliferation in a variety of cells by activating Wnt/PCP signaling...

Receptor tyrosine kinase-like orphan receptor 1 (ROR1) expresses at high level in many cancers and has been suggested as a potential therapeutic target. It was reported that the Kringle (KNG) domain of ROR1 extracellular region is involved in ROR1/ROR2 heterooligomerization. Monoantibodies that target KNG domain of ROR1 could induce apoptosis of chronic lymphocytic leukemia cells. Here we present the backbone and side chain assignments of KNG domain of ROR1, which lays a foundation for its further structural and function research...

Locus heterogeneity characterizes a variety of skeletal dysplasias often due to interacting or overlapping signaling pathways. Robinow syndrome is a skeletal disorder historically refractory to molecular diagnosis, potentially stemming from substantial genetic heterogeneity. All current known pathogenic variants reside in genes within the noncanonical Wnt signaling pathway including ROR2, WNT5A, and more recently, DVL1 and DVL3. However, ∼70% of autosomal-dominant Robinow syndrome cases remain molecularly unsolved...

Background: We have reported that the phosphatidylinositol-3 kinase (PI3K)/Akt/RhoA signaling pathway mediates Wnt5a-induced cell migration of osteosarcoma cells. However, the specific receptors responding to Wnt5a ligand remain poorly defined in osteosarcoma metastasis. Methods: Wound healing assays were used to measure the migration rate of osteosarcoma cells transfected with shRNA or siRNA specific against ROR2 or indicated constructs. We evaluated the RhoA activation in osteosarcoma MG-63 and U2OS cells with RhoA activation assay...

BACKGROUND: In addition to additive genetic effects, epistatic interactions can play key roles in the control of phenotypic variation of traits of interest. In the current study, 475 male birds from lean and fat chicken lines were utilized as a resource population to detect significant epistatic effects associated with growth and carcass traits. RESULTS: A total of 421 significant epistatic effects were associated with testis weight (TeW), from which 11 sub-networks (Sub-network1 to Sub-network11) were constructed...

BACKGROUND: Solid epidemiological evidences connect obesity with incidence, stage, and survival in pancreatic cancer. However, the underlying mechanistic basis linking adipocytes to pancreatic cancer progression remain largely elusive. We hypothesized that factors secreted by adipocytes could be responsible for epithelial-to-mesenchymal transition (EMT) induction and, in turn, a more aggressive phenotype in models of pancreatic preneoplastic lesions. METHODS: We studied the role of factors secreted by two adipogenic model systems from primary human Bone Marrow Stromal Cells (hBMSC) in an in vitro experimental cell transformation model system of human pancreatic ductal epithelial (HPDE) cell stably expressing activated KRAS (HPDE/KRAS),RESULTS:We measured a significant induction of EMT and aggressiveness in HPDE and HPDE/KRAS cell lines when cultured with medium conditioned by fully differentiated adipocytes (ADIPO(CM)) if compared with the same cells cultured with medium conditioned by hBMSC (hBMSC(CM)) from two different healthy donors...

The tyrosine kinase-like orphan receptor 2 (ROR2) has a wnt-mediated, pro-tumorigenic role in certain types of cancer. The present study was designed to assess the protein expression level of ROR2 and its putative ligand Wnt member 5a (Wnt5a), as well as the association with clinicopathological features in papillary thyroid carcinoma (PTC). A total of 58 patients were recruited, resulting in 58 human PTC tissue samples and their paired adjacent noncancerous tissue samples being obtained. The protein expression levels of ROR2 and Wnt5a were evaluated by immunohistochemistry and western blotting, and messenger RNA expression levels were determined by reverse transcription-quantitative polymerase chain reaction...

The submandibular gland (SMG) is one of the major salivary glands that play important roles for variety of physiological functions, such as digestion of foods, prevention of infection, and lubrication of the mouth. Dysfunction of the SMG, often associated with a salivary inflammation, adversely influences a person's quality of life. However, the mechanism underlying inflammation-driven dysfunction of the SMG is largely unknown. Here, we used a mouse model in which the main excretory duct of the SMG is ligated unilaterally to induce inflammation of the gland and examined the expression of Wnt5a, Ror1 and Ror2 genes, encoding Wnt5a ligand and its cognate receptors, which have been implicated in tissue damage or inflammatory responses in variety of tissues...

A recent study indicated that high Wnt5a expression is associated with poor prognosis in NSCLC patients, however, the underlying mechanism was not clear yet. Immunohistochemistry and Western blotting was performed to examine the protein expression level in NSCLC tissues and cell lines. The role of Wnt5a in clone formation, invasiveness, migration and epithelial-to-mesenchymal transition (EMT) of NSCLC cells were studied. Luciferase reporter assay was used to evaluate the Tcf/Lef transcriptional activity. For assessing the effects of Wnt5a on tumor growth and metastasis in vivo , A549 cells transfected with sh-Wnt5a were subcutaneously or orthotopically injected into nude mice...

Specific syntaxins, such as Arabidopsis AtPEN1 and its barley ortholog ROR2, play a major role in plant defense against powdery mildews. Indeed, the impairment of these genes results in increased fungal penetration in both host and non-host interactions. In this study, a genome-wide survey allowed the identification of 21 tomato syntaxins. Two of them, named SlPEN1a and SlPEN1b, are closely related to AtPEN1. RNAi-based silencing of SlPEN1a in a tomato line carrying a loss-of-function mutation of the susceptibility gene SlMLO1 led to compromised resistance toward the tomato powdery mildew fungus Oidium neolycopersici...

Wnt signaling controls multiple biological process, particularly the embryonic development of metazoans. Sustained expression of Wnt signaling components in the mature mammalian CNS and their apparent deregulation in certain neuropathologies suggest that it also plays a part beyond embryonic development to regulate normal brain function. We describe a noncanonical Wnt/Ca(2+) signaling cascade that regulates the electrophysiological intrinsic properties of rat neurons, resulting in sustained membrane depolarization and the mobilization of Ca(2+) from internal stores...

Cytoskeletal reorganization in osteoclasts to form actin rings is necessary for these cells to attach to bone and resorb bone matrices. We delineated the pathway through which Wnt5a signaling through receptor tyrosine kinase-like orphan receptor 2 (Ror2) promoted the bone-resorbing activity of osteoclasts. Wnt5a binding to Ror2 stimulated Rho, a small GTPase involved in cytoskeletal reorganization. Subsequently, the Rho effector kinase Pkn3 bound to and enhanced the activity of c-Src, a nonreceptor tyrosine kinase that is critical for actin ring formation...

Effective targeting of cancer stem cells (CSCs) requires neutralization of self-renewal and chemoresistance, but these phenotypes are often regulated by distinct molecular mechanisms. Here we report the ability to target both of these phenotypes via CD55, an intrinsic cell surface complement inhibitor, which was identified in a comparative analysis between CSCs and non-CSCs in endometrioid cancer models. In this context, CD55 functions in a complement-independent manner and required lipid raft localization for CSC maintenance and cisplatin resistance...

Multipotent mesenchymal stem cells (MSCs) have enormous potential in tissue engineering and regenerative medicine. However, until now, their development for clinical use has been severely limited as they are a mixed population of cells with varying capacities for lineage differentiation and tissue formation. Here, we identify receptor tyrosine kinase-like orphan receptor 2 (ROR2) as a cell surface marker expressed by those MSCs with an enhanced capacity for cartilage formation. We generated clonal human MSC populations with varying capacities for chondrogenesis...

Owing to their high affinities and specificities, rabbit monoclonal antibodies (mAbs) have demonstrated value and potential primarily as basic research and diagnostic reagents, but, in some cases, also as therapeutics. To accelerate access to rabbit mAbs bypassing immunization, we generated a large naïve rabbit antibody repertoire represented by a phage display library encompassing >10 billion independent antibodies in chimeric rabbit/human Fab format and validated it by next-generation sequencing. Panels of rabbit mAbs selected from this library against two emerging cancer targets, ROR1 and ROR2, revealed high diversity, affinity, and specificity...
