Description
Wnt-4 signaling is critical for embryonic female sexual development. When Wnt-4 gene is deleted during embryonic development, the knock-out females present a partial sex reversal.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Three-dimensional (3D) organoids provide a new way to model various diseases, including cancer. We made use of recently developed kidney-organ-primordia tissue-engineering technologies to create novel renal organoids for cancer gene discovery. We then tested whether our novel assays can be used to examine kidney cancer development. First, we identified the transcriptomic profiles of quiescent embryonic mouse metanephric mesenchyme (MM) and of MM in which the nephrogenesis program had been induced ex vivo. The transcriptome profiles were then compared to the profiles of tumor biopsies from renal cell carcinoma (RCC) patients, and control samples from the same kidneys. Certain signature genes were identified that correlated in the developmentally induced MM and RCC, including components of the caveolar-mediated endocytosis signaling pathway. An efficient siRNA-mediated knockdown (KD) of Bnip3, Gsn, Lgals3, Pax8, Cav1, Egfr or Itgb2 gene expression was achieved in mouse RCC (Renca) cells. The live-cell imaging analysis revealed inhibition of cell migration and cell viability in the gene-KD Renca cells in comparison to Renca controls. Upon siRNA treatment, the transwell invasion capacity of Renca cells was also inhibited. Finally, we mixed the nephron progenitors with yellow fluorescent protein (YFP)-expressing Renca cells to establish chimera organoids. Strikingly, we found that the Bnip3-, Cav1- and Gsn-KD Renca-YFP+ cells as a chimera with the MM in 3D organoid rescued, in part, the RCC-mediated inhibition of the nephrogenesis program during epithelial tubules formation. Altogether, our research indicates that comparing renal ontogenesis control genes to the genes involved in kidney cancer may provide new growth-associated gene screens and that 3D RCC-MM chimera organoids can serve as a novel model with which to investigate the behavioral roles of cancer cells within the context of emergent complex tissue structures.

Description
Bile acids play multiple roles in vertebrate metabolism by facilitating lipid absorption in the intestine and acting as a signaling molecule in lipid and carbohydrate metabolism. Bile acids are also the main route to excrete excess cholesterol out of the body. Alpha-methyl-Coa racemase (Amacr) is one of the enzymes needed to produce bile acids from cholesterol. The mouse model lacking Amacr can produce only minor (less than 10%) amounts of bile acids, but still they are symptomless in normal laboratory conditions.

Description
Transforming growth factor beta 1 (TGF-1) is the most extensively studied growth factor in dentin-pulp complex, with pleiotropic effects on pulp response and healing. Our main objective was to analyze the expression profile of pulp tissue and odontoblasts, and the effects of TGF-1 on these profiles in cultured human pulp and odontoblasts with a specific interest in the anti- and pro-inflammatory cytokines.

Description
Multiple miliary osteoma cutis (MMOC) is a rare skin disorder characterized by heterotopic ossification in dermis and subcutis. The etiology and disease mechanism is unknown, but earlier data indicates that it seems to be different from other diseases containing heterotopic intramembranous ossification. The purpose of this study was to further investigate the pathogenesis of MMOC by comparing patients osteoma affected skin area to their unaffected healthy skin area, as well as to skin from controls. This comparison was made by using osteogenic differentiation studies in cell cultures and by gene expression experiments. Both patient and control dermal fibroblast-like cells were able to differentiate into osteoblast-like matrix mineralizing cells. The differentiation seems to diminish with bone morphogenetic protein (BMP) 4 and 2/7 exposures and seems to correlate with proportion of stem cell associated cell surface marker CD105 positive cells. Microarray analysis revealed altered gene expression patterns between skin samples of patients and controls, as well as between samples taken from different skin areas. BMP receptor II and G-protein -stimulatory subunit genes were among downregulated and -catenin among upregulated genes in patient compared to control samples. Genes for homeobox proteins were among downregulated and gene for secreted frizzled related protein 2 among upregulated genes when compared patients osteoma area to their unaffected area. Differences in unaffected skin area in patients and controls suggest that the nature of MMOC may be more systemic than previously thought. Detected differences in separate skin areas may, in turn, provide new information for understanding the localized characteristics of MMOC. BMPs inhibitory effect to osteogenic differentiation of human dermal fibroblast-like cells may provide a new perspective to the clinical use of BMPs.
