The genetic contribution to human T2D and related metabolic disorders is evident, and mostly follows polygenic inheritance. The TALLYHO/ JngJ (TH) mice are a polygenic model for T2D characterized by obesity, hyperinsulinemia, impaired glucose uptake and tolerance, hyperlipidemia, and hyperglycemia. -

The Role of Primary Cilia in the Crosstalk Between the Ubiquitin–Proteasome System and Autophagy
cells Review The Role of Primary Cilia in the Crosstalk between the Ubiquitin–Proteasome System and Autophagy Antonia Wiegering, Ulrich Rüther and Christoph Gerhardt * Institute for Animal Developmental and Molecular Biology, Heinrich Heine University, 40225 Düsseldorf, Germany; [email protected] (A.W.); [email protected] (U.R.) * Correspondence: [email protected]; Tel.: +49-(0)211-81-12236 Received: 29 December 2018; Accepted: 11 March 2019; Published: 14 March 2019 Abstract: Protein degradation is a pivotal process for eukaryotic development and homeostasis. The majority of proteins are degraded by the ubiquitin–proteasome system and by autophagy. Recent studies describe a crosstalk between these two main eukaryotic degradation systems which allows for establishing a kind of safety mechanism. If one of these degradation systems is hampered, the other compensates for this defect. The mechanism behind this crosstalk is poorly understood. Novel studies suggest that primary cilia, little cellular protrusions, are involved in the regulation of the crosstalk between the two degradation systems. In this review article, we summarise the current knowledge about the association between cilia, the ubiquitin–proteasome system and autophagy. Keywords: protein aggregation; neurodegenerative diseases; OFD1; BBS4; RPGRIP1L; hedgehog; mTOR; IFT; GLI 1. Introduction Protein aggregates are huge protein accumulations that develop as a consequence of misfolded proteins. The occurrence of protein aggregates is associated with the development of neurodegenerative diseases, such as Huntington’s disease, prion disorders, Alzheimer’s disease and Parkinson’s disease [1–3], demonstrating that the degradation of incorrectly folded proteins is of eminent importance for human health. In addition to the destruction of useless and dangerous proteins (protein quality control), protein degradation is an important process to regulate the cell cycle, to govern transcription and also to control intra- and intercellular signal transduction [4–6]. -
Renal Cystic Disorders Infosheet 6-14-19
Next Generation Sequencing Panel for Renal Cystic Disorders Clinical Features: Renal cystic diseases are a genetically heterogeneous group of conditions characterized By isolated renal disease or renal cysts in conjunction with extrarenal features (1). Age of onset of renal cystic disease ranges from neonatal to adult onset. Common features of renal cystic diseases include renal insufficiency and progression to end stage renal disease (ESRD). Identification of the genetic etiology of renal cystic disease can aid in appropriate clinical management of the affected patient. Our Renal Cystic Disorders Panel includes sequence and deletion/duplicaton analysis of all 79 genes listed below.

Molecular Studies of Phenotype Variation in Canine RPGR-XLPRA1 Abstract Purpose: Canine X-linked progressive retinal atrophy 1 (XLPRA1) caused by a mutation in retinitis pigmentosa (RP) GTPase regulator (RPGR) exon ORF15 showed significant ariabilityv in disease onset in a colony of dogs that all inherited the same mutant X chromosome. Defective protein trafficking has been detected in XLPRA1 before any discernible degeneration of the photoreceptors. We hypothesized that the severity of the photoreceptor degeneration in affected dogs may be associated with defects in genes involved in ciliary trafficking.o T this end, we examined six genes as potential disease modifiers. eW also examined the expression levels of 24 genes involved in ciliary trafficking (seven), visual pathway (five), neuronal maintenance genes (six), and cellular stress response (six) to evaluate their possible involvement in early stages of the disease. Methods: Samples from a pedigree derived from a single XLPRA1-affected male dog outcrossed to unrelated healthy mix-bred or purebred females were used for immunohistochemistry (IHC), western blot, mutational and haplotype analysis, and gene expression (GE). -
Selective Loss of RPGRIP1-Dependent Ciliary Targeting of NPHP4, RPGR and SDCCAG8 Underlies the Degeneration of Photoreceptor Neurons
Citation: Cell Death and Disease (2012) 3, e355; doi:10.1038/cddis.2012.96 & 2012 Macmillan Publishers Limited All rights reserved 2041-4889/12 www.nature.com/cddis Selective loss of RPGRIP1-dependent ciliary targeting of NPHP4, RPGR and SDCCAG8 underlies the degeneration of photoreceptor neurons H Patil1,3, N Tserentsoodol1,3, A Saha1, Y Hao1, M Webb1 and PA Ferreira*,1,2 The retinitis pigmentosa GTPase regulator (RPGR) and nephrocystin-4 (NPHP4) comprise two key partners of the assembly complex of the RPGR-interacting protein 1 (RPGRIP1). Mutations in RPGR and NPHP4 are linked to severe multisystemic diseases with strong retinal involvement of photoreceptor neurons, whereas those in RPGRIP1 cause the fulminant photoreceptor dystrophy, Leber congenital amaurosis (LCA). Further, mutations in Rpgrip1 and Nphp4 suppress the elaboration of the outer segment compartment of photoreceptor neurons by elusive mechanisms, the understanding of which has critical implications in uncovering the pathogenesis of syndromic retinal dystrophies. Here we show RPGRIP1 localizes to the photoreceptor connecting cilium (CC) distally to the centriole/basal body marker, centrin-2 and the ciliary marker, acetylated-a- tubulin. NPHP4 abuts proximally RPGRIP1, RPGR and the serologically defined colon cancer antigen-8 (SDCCAG8), a protein thought to partake in the RPGRIP1 interactome and implicated also in retinal–renal ciliopathies. Ultrastructurally, RPGRIP1 localizes exclusively throughout the photoreceptor CC and Rpgrip1nmf247 photoreceptors present shorter cilia with a ruffled membrane. Strikingly, Rpgrip1nmf247 mice without RPGRIP1 expression lack NPHP4 and RPGR in photoreceptor cilia, whereas the SDCCAG8 and acetylated-a-tubulin ciliary localizations are strongly decreased, even though the NPHP4 and SDCCAG8 expression levels are unaffected and those of acetylated-a-tubulin and c-tubulin are upregulated. -

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in
