Candidate gene analysis on MMTV-Cre;Vangl2<sup>flox/flox</sup> and Vangl2<sup>Lp/Lp</sup> tissue reveals a significant reduction in Bmi1 expression, with overexpression of Bmi1 rescuing defects in Vangl2 knockdown cysts.
LPP1-induced decreases in MMPs in mouse tumors created with MDA-MB-231 cells were accompanied by increased collagen in the tumors and fewer lung metastases.
VPA could induce CHD (P < 0.001) and inhibit mRNA or protein expression of Hdac1/2/3 as well as Vangl2/Scrib in fetal hearts, in association with total Hdac activity repression (all P < 0.05).
In addition, by interrogating microarray data from two cohorts of renal patients, we report increased VANGL2 transcript levels in the glomeruli of individuals with focal segmental glomerulosclerosis, suggesting that the molecule may also be involved in certain human glomerular diseases.
Targeted genetic deletion of Vangl2 in mouse glomerular epithelial podocytes enhanced the severity of not only irreversible accelerated nephrotoxic nephritis but also lipopolysaccharide-induced reversible glomerular damage.
Subsequently, using the quantitative RT-PCR analysis, we confirmed that in Wnt signaling pathway, the mRNA levels of Dickkopf WNT Signaling Pathway Inhibitor 2 (DKK2), Sex-determining Region Y-box 17 (SOX17), MYC, Cyclin D1, Calcium/Calmodulin Dependent Protein Kinase II Alpha (CAMK2A), and Wnt Family Member 11 and 5 were increased in facet joint osteoarthritis, while the mRNA levels of WNT Inhibitory Factor 1, Casein Kinase 1 Alpha 1, Transcription Factor 7/Lymphoid Enhancer Binding Factor 1 (TCF7/LEF1), and VANGL Planar Cell Polarity Protein 2 were decreased.
Expression of constitutively active and dominant-negative isoforms of RHOA revealed that it acts downstream of VANGL2 to regulate proliferation and maintenance of TPCs in human RMS.

Here, we show that Van Gogh-like 2 (Vangl2), a core regulator of the non-canonical Wnt/planar cell polarity (Wnt/PCP) pathway, affects TPC self-renewal in rhabdomyosarcoma (RMS)-a pediatric cancer of muscle.
Expression of constitutively active and dominant-negative isoforms of RHOA revealed that it acts downstream of VANGL2 to regulate proliferation and maintenance of TPCs in human RMS.
In a first series of experiments, immortalized macrophages were cultured with LPp1 for 24 h. Then, cytotoxicity of chitinase isoforms (LPp1-P1 to P6) was evaluated against HCT-116 (colon carcinoma), OVCAR-8 (ovarian carcinoma), and SF-295 (glioblastoma) tumor cell lines in 96-well plates.
Here we demonstrate that several components of the planar cell polarity (PCP) arm of non-canonical Wnt signaling including VANGL1, VANGL2 and FZD7 are transcriptionally upregulated in glioma and correlate with poorer patient outcome.
Eleven of 25 diplopic patients (44%) had retinal misregistration as the sole cause (central-peripheral rivalry-type diplopia), 7 (28%) strabismus (1 of 7 initally appeared to have central-peripheral rivalry-type diplopia), 1 (4%) optical/refractive error (monocular diplopia), 2 (8%) mixed retinal misregistration (central-peripheral rivalry-type diplopia) and strabismus, and for 4 (16%) diplopia cause was indeterminate.
AMI, followed by reperfusion, was induced in four groups of male Wistar rats, which subsequently received an intravenous 1 × 10<sup>6</sup> StB bolus 1 day post-AMI (StB1; n = 8), 7 days post-AMI (StB7; n = 9), at both time points (StB1+7; n = 7) or neither (Control; n = 7).

Here we show that high expression of the PCP core genes Prickle1 and Vangl2 is associated with low-risk neuroblastoma, suppression of neuroblastoma cell growth and decreased Wnt/β-catenin signaling.
