  • Dissection of the Role of VIMP in Endoplasmic Reticulum-Associated
    www.nature.com/scientificreports OPEN Dissection of the Role of VIMP in Endoplasmic Reticulum-Associated Degradation of CFTRΔF508 Received: 10 November 2017 Xia Hou1,2, Hongguang Wei1, Carthic Rajagopalan1, Hong Jiang1, Qingtian Wu2, Accepted: 6 March 2018 Khalequz Zaman3, Youming Xie4 & Fei Sun1 Published: xx xx xxxx Endoplasmic reticulum (ER)-associated protein degradation (ERAD) is an important quality control mechanism that eliminates misfolded proteins from the ER. The Derlin-1/VCP/VIMP protein complex plays an essential role in ERAD. Although the roles of Derlin-1 and VCP are relatively clear, the functional activity of VIMP in ERAD remains to be understood. Here we investigate the role of VIMP in the degradation of CFTRΔF508, a cystic fbrosis transmembrane conductance regulator (CFTR) mutant known to be a substrate of ERAD. Overexpression of VIMP markedly enhances the degradation of CFTRΔF508, whereas knockdown of VIMP increases its half-life. We demonstrate that VIMP is associated with CFTRΔF508 and the RNF5 E3 ubiquitin ligase (also known as RMA1). Thus, VIMP not only forms a complex with Derlin-1 and VCP, but may also participate in recruiting substrates and E3 ubiquitin ligases. We further show that blocking CFTRΔF508 degradation by knockdown of VIMP substantially augments the efect of VX809, a drug that allows a fraction of CFTRΔF508 to fold properly and mobilize from ER to cell surface for normal functioning. This study provides insight into the role of VIMP in ERAD and presents a potential target for the treatment of cystic fbrosis patients carrying the CFTRΔF508 mutation. Elimination of misfolded endoplasmic reticulum (ER) proteins by the ER-associated protein degradation (ERAD) pathway is an important physiological adaptation to ER stress1,2.

  • The Hippo Pathway Component Wwc2 Is a Key Regulator of Embryonic Development and Angiogenesis in Mice Anke Hermann1,Guangmingwu2, Pavel I
    Hermann et al. Cell Death and Disease (2021) 12:117 https://doi.org/10.1038/s41419-021-03409-0 Cell Death & Disease ARTICLE Open Access The Hippo pathway component Wwc2 is a key regulator of embryonic development and angiogenesis in mice Anke Hermann1,GuangmingWu2, Pavel I. Nedvetsky1,ViktoriaC.Brücher3, Charlotte Egbring3, Jakob Bonse1, Verena Höffken1, Dirk Oliver Wennmann1, Matthias Marks4,MichaelP.Krahn 1,HansSchöler5,PeterHeiduschka3, Hermann Pavenstädt1 and Joachim Kremerskothen1 Abstract The WW-and-C2-domain-containing (WWC) protein family is involved in the regulation of cell differentiation, cell proliferation, and organ growth control. As upstream components of the Hippo signaling pathway, WWC proteins activate the Large tumor suppressor (LATS) kinase that in turn phosphorylates Yes-associated protein (YAP) and its paralog Transcriptional coactivator-with-PDZ-binding motif (TAZ) preventing their nuclear import and transcriptional activity. Inhibition of WWC expression leads to downregulation of the Hippo pathway, increased expression of YAP/ TAZ target genes and enhanced organ growth. In mice, a ubiquitous Wwc1 knockout (KO) induces a mild neurological phenotype with no impact on embryogenesis or organ growth. In contrast, we could show here that ubiquitous deletion of Wwc2 in mice leads to early embryonic lethality. Wwc2 KO embryos display growth retardation, a disturbed placenta development, impaired vascularization, and finally embryonic death. A whole-transcriptome analysis of embryos lacking Wwc2 revealed a massive deregulation of gene expression with impact on cell fate determination, 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; cell metabolism, and angiogenesis. Consequently, a perinatal, endothelial-specific Wwc2 KO in mice led to disturbed vessel formation and vascular hypersprouting in the retina.

Correspondence to: Xiang Xie. Department of Cardiology, First Affiliated Hospital of Xinjiang Medical University, No. 137, Liyushan Road, Urumqi 830011, China. Email: [email protected]. Background: Selenoprotein S (SelS) is a novel selenoprotein encoded by the SelS gene on chromosome 15q26.3. SelS is associated with the development of diabetes, dyslipidemia and macrovascular complications. However, the relationship between genetic polymorphisms of SelS and coronary artery disease (CAD) remains unclear. Methods: In the present study, we genotyped four single nucleotide polymorphisms (rs117613208, rs117512970, rs986500879, rs542989868) of SelS gene using direct sequencing method in a case-control study (576 CAD cases and 452 control subjects). Furthermore, we developed a predictive model using SelS genetic variation and clinical variables to predict risk of CAD. Results: We found that rs117613208 T allele was more frequent in the CAD cases than that in the controls.

The effect of -tocotrienol, a vitamin E isomer, in modulating gene expression in cellular aging of human diploid fibroblasts was studied. Senescent cells at passage 30 were incubated with 70 Mof-tocotrienol for 24 h. Gene expression patterns were evaluated using Sentrix HumanRef-8 Expression BeadChip from Illumina, analysed using GeneSpring GX10 software, and validated using quantitative RT-PCR. A total of 100 genes were differentially expressed ( < 0.001)byatleast1.5foldinresponseto-tocotrienol treatment. Amongst the genes were IRAK3, SelS, HSPA5, HERPUD1, DNAJB9, SEPR1, C18orf55, ARF4, RINT1, NXT1, CADPS2, COG6,andGLRX5. Significant gene list was further analysed by Gene Set Enrichment Analysis (GSEA), and the Normalized Enrichment Score (NES) showed that biological processes such as inflammation, protein transport, apoptosis, and cell redox homeostasis were modulated in senescent fibroblasts treated with -tocotrienol.

  • Drosophila and Human Transcriptomic Data Mining Provides Evidence for Therapeutic
    Drosophila and human transcriptomic data mining provides evidence for therapeutic mechanism of pentylenetetrazole in Down syndrome Author Abhay Sharma Institute of Genomics and Integrative Biology Council of Scientific and Industrial Research Delhi University Campus, Mall Road Delhi 110007, India Tel: +91-11-27666156, Fax: +91-11-27662407 Email: [email protected] Nature Precedings : hdl:10101/npre.2010.4330.1 Posted 5 Apr 2010 Running head: Pentylenetetrazole mechanism in Down syndrome 1 Abstract Pentylenetetrazole (PTZ) has recently been found to ameliorate cognitive impairment in rodent models of Down syndrome (DS). The mechanism underlying PTZ’s therapeutic effect is however not clear. Microarray profiling has previously reported differential expression of genes in DS. No mammalian transcriptomic data on PTZ treatment however exists. Nevertheless, a Drosophila model inspired by rodent models of PTZ induced kindling plasticity has recently been described. Microarray profiling has shown PTZ’s downregulatory effect on gene expression in fly heads. In a comparative transcriptomics approach, I have analyzed the available microarray data in order to identify potential mechanism of PTZ action in DS. I find that transcriptomic correlates of chronic PTZ in Drosophila and DS counteract each other. A significant enrichment is observed between PTZ downregulated and DS upregulated genes, and a significant depletion between PTZ downregulated and DS dowwnregulated genes. Further, the common genes in PTZ Nature Precedings : hdl:10101/npre.2010.4330.1 Posted 5 Apr 2010 downregulated and DS upregulated sets show enrichment for MAP kinase pathway. My analysis suggests that downregulation of MAP kinase pathway may mediate therapeutic effect of PTZ in DS. Existing evidence implicating MAP kinase pathway in DS supports this observation.

  • Identification of Intima-To-Media Signals for Flow-Induced Vascular Remodeling Using Correlative Gene Expression Analysis
    www.nature.com/scientificreports OPEN Identifcation of intima‑to‑media signals for fow‑induced vascular remodeling using correlative gene expression analysis John Kolega1,2*, Kerry E. Poppenberg1,3, Hee‑Woong Lim4, Liza C. Gutierrez1,3, Sricharan S. Veeturi1,5, Adnan H. Siddiqui1,3, Hamidreza Rajabzadeh‑Oghaz1,3 & Vincent M. Tutino1,2,3,5 Changes in blood fow can induce arterial remodeling. Intimal cells sense fow and send signals to the media to initiate remodeling. However, the nature of such intima‑media signaling is not fully understood. To identify potential signals, New Zealand white rabbits underwent bilateral carotid ligation to increase fow in the basilar artery or sham surgery (n = 2 ligated, n = 2 sham). Flow was measured by transcranial Doppler ultrasonography, vessel geometry was determined by 3D angiography, and hemodynamics were quantifed by computational fuid dynamics. 24 h post‑surgery, the basilar artery and terminus were embedded for sectioning. Intima and media were separately microdissected from the sections, and whole transcriptomes were obtained by RNA‑seq. Correlation analysis of expression across all possible intima‑media gene pairs revealed potential remodeling signals. Carotid ligation increased fow in the basilar artery and terminus and caused diferential expression of 194 intimal genes and 529 medial genes. 29,777 intima‑media gene pairs exhibited correlated expression. 18 intimal genes had > 200 medial correlates and coded for extracellular products. Gene ontology of the medial correlates showed enrichment of organonitrogen metabolism, leukocyte activation/immune response, and secretion/exocytosis processes. This demonstrates correlative expression analysis of intimal and medial genes can reveal novel signals that may regulate fow‑induced arterial remodeling.

  • Protein Folding and Quality Control in the ER

The ERQC facilitates folding and modification of secretory and mem- brane proteins and eliminates terminally misfolded polypeptides through ER-associated degradation (ERAD) or autophagic degradation. This mechanism of ER protein surveillance is closely linked to redox and calcium homeostasis in the ER, whose balance is presumed to be regulated by a specific cellular compartment. The potential to modulate proteostasis and metabolism with chemical compounds or targeted siRNAs may offer an ideal option for the treatment of disease. he endoplasmic reticulum (ER) serves as a complex in the ER membrane (Johnson and Tprotein-folding factory where elaborate Van Waes 1999; Saraogi and Shan 2011).

  • A Membrane Protein Complex Mediates Retro-Translocation from the ER Lumen Into the Cytosol
    articles A membrane protein complex mediates retro-translocation from the ER lumen into the cytosol Yihong Ye1, Yoko Shibata1, Chi Yun2, David Ron2 & Tom A. Rapoport1 1Howard Hughes Medical Institute and Department of Cell Biology, Harvard Medical School, 240 Longwood Avenue, Boston, Massachusetts 02115, USA 2Skirball Institute, New York University School of Medicine, New York, New York 10016, USA ........................................................................................................................................................................................................................... Elimination of misfolded proteins from the endoplasmic reticulum (ER) by retro-translocation is an important physiological adaptation to ER stress. This process requires recognition of a substrate in the ER lumen and its subsequent movement through the membrane by the cytosolic p97 ATPase. Here we identify a p97-interacting membrane protein complex in the mammalian ER that links these two events. The central component of the complex, Derlin-1, is a homologue of Der1, a yeast protein whose inactivation prevents the elimination of misfolded luminal ER proteins. Derlin-1 associates with different substrates as they move through the membrane, and inactivation of Derlin-1 in C. elegans causes ER stress. Derlin-1 interacts with US11, a virally encoded ER protein that specifically targets MHC class I heavy chains for export from the ER, as well as with VIMP, a novel membrane protein that recruits the p97 ATPase and its cofactor. Many proteins of eukaryotic cells undergo folding and modification the ER lumen and the function of p97 in the cytosol. Here we report in the lumen of the endoplasmic reticulum (ER). Properly folded the identification of a membrane protein complex that provides this polypeptides leave the ER along the secretory pathway, whereas link.
