Abstract
Neurturin (NRTN) is one of the glial cell line-derived neurotrophic factor family ligands crucial for neuron growth, differentiation and maintenance. Recent studies showed NRTN promotes an aggressive pancreatic cancer phenotype, and predicts shorter survival in lung cancer patients. However, its expression and function in colorectal cancer (CRC) remain unclear. Herein, we found NRTN was enriched in CRC cells, and predicted poor patients outcomes. Upregulated NRTN enhanced the migration and invasion of CRC cells and vascularization of endothelial cells. In mechanism, NRTN promoted ZEB1/N-cadherin and vascular endothelial growth factor (VEGF)-A expression in CRC cells, which were responsible for tumor cell motility and angiogenesis, respectively. More importantly, NRTN inhibition prevented CRC metastasis and angiogenesis in vivo. In conclusion, NRTN promotes CRC cells motility and tumor angiogenesis via inducing ZEB1/N-cadherin and VEGF-A overexpression. It is a potential therapeutic target and negative prognostic biomarker for CRC patients.

Abstract
Wilms tumour (WT) is an embryonal tumour that recapitulates kidney development. The normal kidney is formed from two distinct embryological origins: the metanephric mesenchyme (MM) and the ureteric bud (UB). It is generally accepted that WT arises from precursor cells in the MM; however whether UB-equivalent structures participate in tumorigenesis is uncertain. To address the question of the involvement of UB, we assessed 55 Wilms tumours for the molecular features of MM and UB using gene expression profiling, immunohistochemsitry and immunofluorescence. Expression profiling primarily based on the Genitourinary Molecular Anatomy Project data identified molecular signatures of the UB and collecting duct as well as those of the proximal and distal tubules in the triphasic histology group. We performed immunolabeling for fetal kidneys and WTs. We focused on a central epithelial blastema pattern which is the characteristic of triphasic histology characterized by UB-like epithelial structures surrounded by MM and MM-derived epithelial structures, evoking the induction/aggregation phase of the developing kidney. The UB-like epithelial structures and surrounding MM and epithelial structures resembling early glomerular epithelium, proximal and distal tubules showed similar expression patterns to those of the developing kidney. These observations indicate WTs can arise from a precursor cell capable of generating the entire kidney, such as the cells of the intermediate mesoderm from which both the MM and UB are derived. Moreover, this provides an explanation for the variable histological features of mesenchymal to epithelial differentiation seen in WT.

Organ, cellular, and subcellular localization of brain-specific anion transporter BSAT1. Bull Exp Biol Med 2013; 155:491-7.

Abstract
Organ, cellular, and subcellular localization of brain-specific anion transporter BSAT1 was studied in rats using antibodies to the extracellular fragment (451-557 a.a). The antibodies were shown to recognize the antigen predominantly localized in the nervous tissue, tumors of glial origin, and primordial ovarian follicles. The absence of BSAT1 immunofluorescence signal in kidney and liver sections and accumulation of (125)I labeled antibodies to BSAT1 in these organs indicate that these antibodies do not cross-react with the most common isoforms of OATP expressed in these organs. Analysis of the cellular localization suggests that in the brain, BSAT1 is localized predominantly in astrocytes, but not in endothelial cells, as was previously reported. Laser scanning confocal microscopy with a set of relevant trackers revealed membrane localization of BSAT1. Taking into account the data on the of localization, we can conclude that antibodies to BSAT1 451-557 can be used for basic research of the transport of thyroxin and prostaglandins across the blood brain barrier and for testing the systems for targeted transport of diagnostic preparations and drugs across the blood brain barrier, e.g. to astroglial tumors.

Abstract
Nephrogenic rests (NR) are foci of embryonal renal tissue that persist beyond the normal period of renal morphogenesis. They are commonly found in kidneys bearing Wilms tumor but may also rarely occur in different locations. Nephrogenic rests have been reported in the lumbosacral area in a total of nine cases, including our case. Of the nine cases, only one case prior to ours showed agenesis of one kidney in association with the NR. We report a 2-year-old female with a lipomyelomeningocele containing NRs and agenesis of the right kidney and discuss the molecular genetic basis of lumbosacral NR.
