Verghese,1 Kinsuk Chauhan,1 Girish N. Nadkarni,1 Zhengzhe Li,1 Wenjun Ju,4 Matthias Kretzler ,4 Guang-Yan Cai,2 Xiang-Mei Chen,2 Vivette D. D’Agati,5 Steven G. Coca ,1 Detlef Schlondorff,1 John C. He,1,6 and Kyung Lee1 Due to the number of contributing authors, the affiliations are listed at the end of this article. ABSTRACT Background Glomerular endothelial dysfunction and neoangiogenesis have long been implicated in the pathogenesis of diabetic kidney disease (DKD). However, the specific molecular pathways contributing to these processes in the early stages of DKD are not well understood. Our recent transcriptomic profiling of glomerular endothelial cells identified a number of proangiogenic genes that were upregulated in diabetic mice, including leucine-rich a-2-glycoprotein 1 (LRG1). LRG1 was previously shown to promote neovascularization in mouse models of ocular disease by potentiating endothelial TGF-b/activin receptor- like kinase 1 (ALK1) signaling. However, LRG1’s role in the kidney, particularly in the setting of DKD, has been unclear. Methods We analyzed expression of LRG1 mRNA in glomeruli of diabetic kidneys and assessed its localization by RNA in situ hybridization. We examined the effects of genetic ablation of Lrg1 on DKD progression in unilaterally nephrectomized, streptozotocin-induced diabetic mice at 12 and 20 weeks after diabetes induction. We also assessed whether plasma LRG1 was associated with renal outcome in patients with type 2 diabetes.

Analysis of Gene Expression Data for Gene Ontology
ANALYSIS OF GENE EXPRESSION DATA FOR GENE ONTOLOGY BASED PROTEIN FUNCTION PREDICTION A Thesis Presented to The Graduate Faculty of The University of Akron In Partial Fulfillment of the Requirements for the Degree Master of Science Robert Daniel Macholan May 2011 ANALYSIS OF GENE EXPRESSION DATA FOR GENE ONTOLOGY BASED PROTEIN FUNCTION PREDICTION Robert Daniel Macholan Thesis Approved: Accepted: _______________________________ _______________________________ Advisor Department Chair Dr. Zhong-Hui Duan Dr. Chien-Chung Chan _______________________________ _______________________________ Committee Member Dean of the College Dr. Chien-Chung Chan Dr. Chand K. Midha _______________________________ _______________________________ Committee Member Dean of the Graduate School Dr. Yingcai Xiao Dr. George R. Newkome _______________________________ Date ii ABSTRACT A tremendous increase in genomic data has encouraged biologists to turn to bioinformatics in order to assist in its interpretation and processing. One of the present challenges that need to be overcome in order to understand this data more completely is the development of a reliable method to accurately predict the function of a protein from its genomic information. This study focuses on developing an effective algorithm for protein function prediction. The algorithm is based on proteins that have similar expression patterns. The similarity of the expression data is determined using a novel measure, the slope matrix. The slope matrix introduces a normalized method for the comparison of expression levels throughout a proteome. The algorithm is tested using real microarray gene expression data. Their functions are characterized using gene ontology annotations. The results of the case study indicate the protein function prediction algorithm developed is comparable to the prediction algorithms that are based on the annotations of homologous proteins.

LRG1) As a Target for a Potential Antibody– Drug Conjugate (ADC
University College London Appraisal of leucine-rich alpha-2-glycoprotein 1 (LRG1) as a target for a potential antibody– drug conjugate (ADC) by Faiza Javaid Submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy Declaration of Authorship I, Faiza Javaid, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Faiza Javaid March 2021 i For mumma and daddy. ii Acknowledgements Bismillah, I could never have imagined that the most important undertaking of my life, and indeed the most important year of my PhD would coincide with a global pandemic. But I still maintain the conviction, Alhamdulillah, that pursuing a PhD has been the greatest (albeit the most challenging) decision I have ever made in my life, and it is in no small part due to the support and friendship of the many people I have had the fortune to meet in the process. When I think of my PhD journey, what comes to mind is not merely the untold hours of growing cells and digesting antibodies, but the sounds of AoE II, Rubiks cube contests (the Chud rites of passage - neither of which I was proficient at, but was nevertheless welcomed into the Chud fold), venturing into previously unexplored corners of YouTube (notably lemonade duck and Danny’s goodbye), that weekend in Portugal, 7 days aka the Chud anthem, numerous games of Chameleon, João’s beautiful face contagious energy and the KLB space project amongst many other interesting events.

Mouse Lrg1 Conditional Knockout Project (CRISPR/Cas9)-Va
http://www.alphaknockout.com/ Mouse Lrg1 Conditional Knockout Project (CRISPR/Cas9)-vA Objective: To create a Lrg1 conditional knockout mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Lrg1 gene ( NCBI Reference Sequence: NM_029796 ; Ensembl: ENSMUSG00000037095 ) is located on mouse chromosome 17. 2 exons are identified , with the ATG start codon in exon 1 and the TGA stop codon in exon 2 (Transcript: ENSMUST00000041357). Exon 2 will be selected as conditional knockout region (cKO region). the second loxP will be inserted downstream of the TGA stop codon. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-180H19 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for a knock-out allele exhibit Tgfbr1-dependent increased growth of LCC tumor allografts. The knockout of Exon 2 will result in frameshift of the gene, and covers 97.47% of the coding region. The size of intron 1 for 5'-loxP site insertion: 916 bp. The size of effective cKO region: ~1341 bp. This strategy is designed based on genetic information in existing databases. Due to the complexity of biological processes, all risk of loxP insertion on gene transcription, RNA splicing and protein translation cannot be predicted at existing technological level. The cKO region contains functional region of the Plin5 gene. Knockout the region may

The Plasminogen Protein Is Associated with High Myopia As
www.nature.com/scientificreports OPEN The plasminogen protein is associated with high myopia as revealed by the iTRAQ‑based proteomic analysis of the aqueous humor Kai Wen1,3, Xianfeng Shao1,3, Yahong Li1, Yaoling Li1, Yongtao Li1, Qing Wang1, Ruihong Su1, Lujie Zhang2, Yang Cai1, Jing Sun1* & Yan Zhang1* To explore the pathogenesis of high myopia (HM) using quantitative proteomics. The aqueous humor of patients with simple nuclear cataract and nuclear cataract complicated with HM (hereinafter referred to as “C” and “HM” groups, respectively) were collected. The isobaric tags for relative and absolute quantitation (iTRAQ)‑based liquid chromatography–tandem mass spectrometry (LC– MS/MS) proteomics approach was employed to explore diferentially expressed proteins (DEPs). Bioinformatics was used to interpret the proteomic results. Furthermore, the plasminogen (PLG) protein was confrmed by enzyme‑linked immunosorbent assay (ELISA) as the candidate biomarker for HM through a receiver operating characteristic curve analysis. The study showed 32 upregulated and 26 downregulated proteins. The gene ontology analysis demonstrated that 58 DEPs corresponded to 325 biological processes, 33 cell components, and 45 molecular functional annotations. The Kyoto Encyclopedia of Genes and Genomes analysis showed that the upregulated DEPs were highly enriched in the coagulation and complement cascades, consistent with the gene set enrichment analysis. Our data suggested that some DEPs might be hallmarks of the development of HM. ELISA confrmed that the PLG expression levels were signifcantly upregulated in HM. This was a new study investigating alterations in protein levels and afected pathways in HM using iTRAQ‑based quantitative proteomics. Our study provided a comprehensive dataset on overall protein changes and shed light on its potential molecular mechanism in human HM.

LRG1 Downregulation in Allergic Airway Disorders and Its Expression
Hao et al. J Transl Med (2016) 14:202 DOI 10.1186/s12967-016-0929-2 Journal of Translational Medicine RESEARCH Open Access LRG1 downregulation in allergic airway disorders and its expression in peripheral blood and tissue cells Lijing Hao1,2†, Hua Xie3†, Bin Zhang2†, Dong Chen1, Shufen Wang1,2, Huiyun Zhang1 and Shaoheng He1* Abstract Background: Increased leucine-rich α2-glycoprotein-1 (LRG1) has been observed in plasma of individuals with vari- ous diseases. However, the role of LRG1 in allergic airway disease has not been investigated. Objective: To explore the involvement of LRG1 in allergy and its cell origins. Methods: The expression levels of LRG1 and its receptor transforming growth factor-beta receptor II (TGFBR2) in patients with allergic rhinitis (AR) and asthma (AS) were examined by flow cytometry, and enzyme-linked immuno- sorbent assay (ELISA). Results: LRG1 and soluble TGFBR2 expression in plasma of patients with AR and AS were markedly lower than that of healthy control (HC) subjects. Large proportions of CD123 HLA-DR , CD16 , CD4 , CD8 , CD14 , and CD19 cells expressed LRG1, although the percentages of LRG1 cells+ in these− cell populations+ + were lower+ in +AR and AS + patients. Up to 89.8 and 15.5 % of dispersed mast cells expressed+ LRG1 and TGFBR2. Moreover, allergen extract expo- sure significantly reduced LRG1 and TGFBR2 expression in the plasma and leukocytes of patients with AR and AS. Conclusions: Reduced LRG1 and TGFBR2 levels in patients with allergic airway disorders are likely caused by inhibi- tory actions of allergens in LRG1 producing cells. Thus, LRG1 may be a key regulatory factor of allergic responses.
