About the Edition

In this thesis I investigated the role of the inhibitory Bmp signaling pathway during mouse kidney renal development using (i) genetic haploinsufficiency models to investigate the functions of Bmp2 and Gpc3-Bmp2 interactions during renal development in vivo and (ii) conditional Alk3 loss-of-function in the UB lineage to investigate the function of Alk3-dependent Bmp signaling during RBM in vivo.During embryonic development, the collecting duct system of the kidney arises through iterative growth and branching of the ureteric bud (UB) and daughter collecting ducts, a process termed renal branching morphogenesis (RBM). Previous work in our lab identified an inhibitory ALK3-dependent BMP signaling pathway that controls cellular and morphogenetic events during RBM in vitro and in transgenic over-expression mouse models. However, the early embryonic lethality of homozygous Bmp2-/- and Alk3-/- mice has precluded complementary conventional loss-of-function studies to define the role of Bmp signaling during renal development in vivo.Results from this thesis provide the first genetic evidence that an inhibitory Bmp2 signaling pathway controls UB cell proliferation and branching during RBM in vivo, and that Bmp2 signaling is genetically modulated by Gpc3. Further, these results demonstrate an essential requirement of ALK3-dependent Bmp signaling for normal kidney development in vivo, and identify a critical architectural role for ALK3 in establishing and maintaining the primary UB branching pattern.

  IGFBP-2 represents a multifunctional protein with effects on growth, reproductive development, aging, and metabolism. For the expression of these diverse effects in vivo, IGFBP-2 has a number of binding sites for IGFs, integrins, and order to assess the relative contributions of these binding sites to the multiple effects of IGFBP-2, we have developed transgenic mouse models Author: Andreas Hoeflich, Anja Reyer, Nancy Schindler, Daniela Ohde, Elisa Wirthgen, Julia Brenmoehl. Clear cell renal cell carcinoma (ccRCC) is characterized by BAP1 and PBRM1 mutation, which are associated with tumors of different grade and prognosis. However, whether BAP1 and PBRM1 loss causes ccRCC and determines tumor grade is unclear. We conditionally targeted Bap1 and Pbrm1 (with Vhl) in the mouse using several Cre drivers. Here, we investigated Clock δ"19/+ heterozygous (Clk/+) mice, known to display lengthened periodicity and dampened amplitude, as a model of partially perturbed clocks. Interestingly, Clk/+ mice exhibited improved glycemic control and resistance to circadian period lengthening under high-fat diet (HFD).Cited by:   Acquired resistance towards apoptosis is a hallmark of cancer.

Inhibitory BMO signaling controls mammalian renal branching morphogenesis in vivo by Sunny Sun-Hee Hartwig Download PDF EPUB FB2

The role of Fgf signaling in branching morphogenesis of the mammalian kidneys is not as well known as in the lungs (reviewed in Blake & Rosenblum, ; Costantini & Kopan, ). Yet, Fgf7-null. Branching morphogenesis, defined as the growth and branching of epithelial tubules, is a fundamental developmental process involved in the formation of a variety of mammalian tissues, including the kidney.

Defective renal branching may result in a number of clinically relevant abnormalities, including renal agenesis, renal dysplasia, multiplex kidneys, and by:   Branching morphogenesis assays.

Branching morphogenesis was induced using slight modifications of previously published protocols (Hirai et al., ; Simian et al., Inhibitory BMO signaling controls mammalian renal branching morphogenesis in vivo book clusters were prepared as follows: EpH4 cells suspended in growth medium containing DNase I were placed on top of agarose-coated wells and incubated at rpm and 37°C on an orbital shaker overnight, yielding Cited by: Inhibitory BMO signaling controls mammalian renal branching morphogenesis in vivo book   Abstract.

The sex of an individual is determined by the fate of the gonad. While the expression of Sry and Sox9 is sufficient to induce male development, we here show that female differentiation requires activation of the canonical β-catenin signaling pathway.

β-catenin activation is controlled by Rspo1 in XX gonads and Rspo1 knockout mice show masculinized by: HGF mediates branching morphogenesis in renal epithelial cells by activating c-met, which then sets into motion a series of downstream signaling pathways.

Our laboratory and others have shown that HGF-induced cell migration and branching morphogenesis are dependent on activation of both the Erk and phosphatidylinositol 3-kinase (PI3-K Cited by:   A considerable body of research indicates that mammary gland branching morphogenesis is dependent, in part, on the extracellular matrix (ECM), ECM-receptors, such as integrins and other ECM receptors, and ECM-degrading enzymes, including matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs).

Recent studies have reported that NF-κB mediated down-regulation of miRNA and lower expression of miRNA promoted the deposition of collagens in fibrotic liver. Our previous research demonstrated that the increased Hedgehog (Hh) signaling, a key regulator for hepatic fibrogenesis, induced the severe hepatic fibrosis in the livers with impaired NF-κB by: Hh signaling also controls the migration of basal epidermal cells to more superficial aspects of adult skin (63, 64).
