WNT10B | bioCADDIE Data Discovery Index
Dear DataMed user: DataMed prototype(v3.0) is being developed for the NIH BD2K Data Discovery Index (DDI) by the bioCADDIE project team. DataMed, once completed, will be of use to the scientific community to allow users to search for and find data across different repositories in one space.
We are soliciting your feedback to help us shape DataMeds' future development. Please take a moment to answer this brief Survey Form and give us your thoughts. We believe your voice will be a critical addition to the development of the bioCADDIE prototype.
Thank you, from the bioCADDIE team.

es in gene expression during dedifferentiation of human articular chondrocytes to identify underlying mechanisms. Methods: RNA was isolated from monolayer-cultured primary human articular chondrocytes at serial passages. Gene expression was analyzed by microarray. Based on the microarray analysis, relevant genes and pathways were identified. Their functions in chondrocyte dedifferentiation were further investigated in detail. Results: In vitro expanded
pression during repair and that expression of the Wnt pathway mediator Tcf4 (aka Tcf7l2) within OLPs is specific to lesioned—but not normal—adult white matter. We report that β-catenin signaling is active during oligodendrocyte development and remyelination in vivo. Moreover, we observed similar regulation of Tcf4 in the developing human CNS and lesions of MS. Data mining revealed elevated levels of Wnt pathway mRNA transcripts and proteins within MS lesions, indicating activation of the pathway in this pathological context. We show that dysregulation of Wnt–β-catenin signaling in OLPs results in profound delay of both developmental myelination and remyelination, based on (1) conditional activation of β-catenin in the oligodendrocyte lineage in vivo and (2) findings from APCMin mice, which lack one f...
TX2, EYA2, OAS1, MITF, TCF20), and members of the Wnt signaling pathway (AXIN2, WISP1, SFRP). Remarkably, almost one fourth of the differentially expressed genes encode proteins associated with inflammation and tissue remodeling, including members of the interferon (IFN), tumor necrosis factor (TNF) and transforming growth factor beta (TGF-beta) signaling pathways as well as metalloproteinases (MMP1, 9, 13, 23), urokinase plasminogen activator (PLAU) and cathepsins. Our observations provide the first comparative molecular characterization of desmoid tumors and nodular fasciitis and suggest that selected tyrosine kinases, transcription factors and members of the Wnt, TGF-beta, IFN and TNF signaling pathways may be implicated in influencing and distinguishing their fate.
Keywords: comparative genomic hybridization
Overall design: 12 desmoid tumors and 6 nodular fasciitis were analyzed using MRC5 as common reference.
One duplicate with dye swap was performed (DT1 dye-swap)...

Overall design: The rats were randomly assigned to one of the three following treatment groups (10-12 animals per group): normal control, radiation and...
is on CXCL12- treated T-cells, and found that the Wntfamily of proteins was significantly upregulated during CXCL12 treatment. Confirmation of these results by real-time PCR and Western analysis indicated that the non-canonical Wnt pathway was specifically upregulated during CXCL12 treatment. In vitro and in vivo knockdown studies confirm that b-catenin (the key mediator of canonical
erestingly, all of the QTL signals co-locate with Wnt growth factors and closely interacting genes (Wnt3a, Wnt5a, Wnt6, Wnt7a, Wnt9a, RhoU and RhoV). Our findings therefore suggest that standing genetic variation in the Wnt genes might be linked to avian wing morphology, although there are many other genes that also fall within the confidence regions....
reated cases indicates activation of noncanonical Wnt signaling (P=0.0064). Ectopic expression of Wnt5a in prostate cancer cells attenuates the antiproliferative effect of AR inhibition, while its suppression in drug-resistant cells restores partial sensitivity, a correlation also evident in an established mouse model. Thus, single cell analysis of prostate CTCs reveals heterogeneity in signaling pathways that could contribute to treatment failure. A total of 221 single candidate prostate CTCs were isolated from 18 patients with metastatic prostate cancer and 4 patients with localized prostate cancer. Of these, 133 cells (60%) had RNA of sufficient quality for amplification and next generation RNA sequencing, and 122 (55%) had >100,000 uniquely aligned sequencing reads. In addition to candidate CTCs, we also obtained comprehens...
cle homolog 2 (NKD2), a negative regulator of the Wnt signaling pathway, to be significantly downregulated in metastatic OS. An assessment of human OS tumors revealed downregulation of NKD2 in metastatic and recurrent OS. We determined that downregulation was secondary to methylation of the NKD2 promoter region for both mouse and human tumors. Furthermore, in vivo investigations indicate that NKD2 overexpression significant...
