Project description:Systemic arterial stenosis, including moyamoya disease (MMD) and middle aortic syndrome (MAS), is a rare condition of unclear etiology. MMD is a cerebral angiopathy, whereas MAS affects abdominal and thoracic aortas, leading to various complications. Although some genetic associations with MAS have been identified, the causes remain elusive. In this study, whole-exome sequencing was used to identify de novo heterozygous missense variants of RING finger protein 213 (RNF213) (p.His4058Pro and p.Thr4155Pro) in two unrelated families exhibiting both MAS and MMD. To understand the significance of these variants, we generated knockin mice carrying the Rnf213 p.His4058Pro variant. Notably, homozygous knockin mice exhibited perinatal lethality due to respiratory failure and lung dysplasia, suggesting that this variant is pathogenic. Lung dysplasia in homozygous knockin mice was associated with upregulated innate immunity and inflammatory responses and downregulated cell proliferation. The findings suggested that in mice, the RNF213 p.His4058Pro variant plays critical roles in lung development, innate immunity, and inflammation, revealing the complexity of RNF213 function in various tissues and species. In conclusion, this study provides insights into the genetic basis of MAS and MMD, highlights the potential involvement of RNF213 variants in systemic vasculopathy, and identifies unexpected associations with lung development and immune processes.

Project description:This is a Phase II, open label, multicentre, multi-arm, study to evaluate the preliminary efficacy and safety of RXC004 as monotherapy and in combination with nivolumab in patients with Ring finger protein 43 (RNF43) or R-spondin (RSPO) aberrated, microsatellite stable (MSS), colorectal cancer (CRC), that have progressed following current standard of care treatment.

Project description:We present the analysis of an osseous finger ring from an early Neolithic context in Denmark. To characterise the artefact and identify the raw material used for its manufacture, we performed micro-computed tomography (Micro CT) scanning, zooarchaeology by mass spectrometry (ZooMS) peptide mass fingerprinting, as well as protein sequencing by liquid chromatography tandem mass spectrometry (LC-MS/MS). We found that the ring was made from long bone or antler due to the presence of osteons (Haversian canals). Subsequent ZooMS analysis of the collagen present indicated that it was made from either elk (Alces alces) or red deer (Cervus elaphus) material. We then used LC-MS/MS analysis to refine our species identification, confirming that the ring was made from red deer, and to examine other proteins present. This study demonstrates the potential of ancient proteomics for species identification of prehistoric artefacts made from osseous material.

Project description:The aim of this study was to help people comprehensively understand the research advances related to ring finger protein 213 (RNF213) in moyamoya disease (MMD) and to understand the disease at the molecular level to provide a new perspective of the diagnosis of the disease.This review was based on data in articles published between 2005 and 2015 that were retrieved from the PubMed database. The search terms included RNF213, MMD, intracranial major artery stenosis /occlusion (ICASO), genotype, phenotype, mutant and variants, and the combinations of these terms.Articles related to MMD and RNF213 were selected for review, and we also reviewed publications related to ICASO.RNF213 is not only associated with MMD but also associated with intracranial major artery stenosis. In addition, RNF213 variants exhibit apparent ethnic diversity; specifically, the c.14576G>A variant is mainly detected in Korean, Chinese, and Japanese populations, particularly the latter population. The genotypes of RNF213 correlate with the phenotypes of MMD; for example, the homozygous c.14576G>A variant is associated with early-onset, severe symptoms, and an unfavorable prognosis. Furthermore, the RNF213 c.14576G>A variant should be considered during the diagnosis of MMD because no patients with quasi-MMD have been reported to carry the RNF213 c.14576G>A variant whereas 66 of 78 patients with definite MMD have been found to carry this variant.The growing literature demonstrates that MMD is primarily caused by the synergy of genetic and environmental factors, and unknown genetic modifiers might play roles in the etiology of MMD. Further research should be conducted to clarify the pathogenic mechanism of MMD.

Project description:Recently, thyroid autoantibodies were found to be associated with moyamoya disease (MMD). The ring finger protein 213 (RNF213) p.R4810K variant represents the most important susceptibility genotype of this disease, but its relationship with thyroid autoantibodies remains to be elucidated. Thus, in this study, we aimed to evaluate the clinical relevance of thyroid autoantibodies in each RNF213 genotype in patients with MMD. Included in this study were patients with MMD without a thyroid disease history and in euthyroid status; they were then classified into the mutated or nonmutated based on the RNF213 p.R4810K genotype and positive or negative based on thyroid autoantibody (thyroperoxidase and thyroglobulin) levels. Clinical data of each group were thereafter evaluated. Among the 209 patients, the mutated RNF213 p.R4810K variant and positive thyroid autoantibodies were detected in 155 and 41 patients, respectively. Positive thyroid autoantibodies were found to be more common in the nonmutated patients than in the mutated patients (31.5% vs. 15.5%; P = 0.011). In the mutated patients, as compared to autoantibody-negative patients, autoantibody-positive patients were determined to be more likely to have advanced disease with posterior cerebral artery involvement (54.2% vs. 29.0%; P = 0.017), white matter infarction (58.3% vs. 37.6%; P = 0.046), and a higher modified Rankin Scale at last visit (16.7% vs. 3.1%; P = 0.021). These results suggest that thyroid autoantibodies can act as an immunity inducer in patients with MMD lacking the susceptibility gene RNF213 p.R4810K variant. Moreover, the simultaneous presence of thyroid autoantibodies and the variant seems to aggravate the disease, which indicates synergy between thyroid autoantibodies and the variant.

Project description:ISG15 is an interferon-stimulated, ubiquitin-like protein that can conjugate to substrate proteins (ISGylation) to counteract microbial infection, but the underlying mechanisms remain elusive. Here, we use a virus-like particle trapping technology to identify ISG15-binding proteins and discover Ring Finger Protein 213 (RNF213) as an ISG15 interactor and cellular sensor of ISGylated proteins. RNF213 is a poorly characterized, interferon-induced megaprotein that is frequently mutated in Moyamoya disease, a rare cerebrovascular disorder. We report that interferon induces ISGylation and oligomerization of RNF213 on lipid droplets, where it acts as a sensor for ISGylated proteins. We show that RNF213 has broad antimicrobial activity in vitro and in vivo, counteracting infection with Listeria monocytogenes, herpes simplex virus 1, human respiratory syncytial virus and coxsackievirus B3, and we observe a striking co-localization of RNF213 with intracellular bacteria. Together, our findings provide molecular insights into the ISGylation pathway and reveal RNF213 as a key antimicrobial effector.

Project description:To determine the role of cardiomyocyte muscle ring finger-1 (MuRF1) in vivo, we employed whole genome microarray expression profiling as a discovery platform to identify genes differentially regulated by MuRF1 using MuRF1-/- and alphaMHC (cardiomyocyte-specific) MuRF1 transgenic mice in a model of pulmonary hypertension-induced right sided heart failure. Mice were placed in hypoxia chambers set at 10.0% oxygen (partial pressure of oxygen roughly 65 mmHg in Albuquerque) and monitored both by the digital feedback control system (Biospherix, Colorado) as well as by a secondary O2/CO2 monitor (O2Cap, OxiGraf, Inc.; Mountain View, CA). The hypoxia exposure lasted 3 weeks with twice-weekly cage changes and standard 12 h light:dark cycle. Multiple genes from the microarray expression profile were quantified in the same RNA samples by real-time PCR to confirm their expression.
