The process of glycan modification is directed by different glycosyltransferases, depending on the cell in which it is expressed. These small carbohydrate molecules consist of multiple glycan families that facilitate cell–cell interactions, protein interactions, and downstream signaling. An alteration of several types of O-glycan core structures have been implicated in multiple cancers, largely due to differential glycosyltransferase expression or activity. Consequently, aberrant O-linked glycosylation has been extensively demonstrated to affect biological function and protein integrity that directly result in cancer growth and progression of several diseases.

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

  • C1GALT1 Enhances Proliferation of Hepatocellular Carcinoma Cells Via Modulating MET Glycosylation and Dimerization
    Published OnlineFirst July 5, 2013; DOI: 10.1158/0008-5472.CAN-13-0869 Cancer Tumor and Stem Cell Biology Research C1GALT1 Enhances Proliferation of Hepatocellular Carcinoma Cells via Modulating MET Glycosylation and Dimerization Yao-Ming Wu1,3, Chiung-Hui Liu2, Miao-Juei Huang2,3, Hong-Shiee Lai1, Po-Huang Lee1, Rey-Heng Hu1, and Min-Chuan Huang2,3 Abstract Altered glycosylation is a hallmark of cancer. The core 1 b1,3-galactosyltransferase (C1GALT1) controls the formation of mucin-type O-glycans, far overlooked and underestimated in cancer. Here, we report that C1GALT1 mRNA and protein are frequently overexpressed in hepatocellular carcinoma tumors compared with nontumor liver tissues, where it correlates with advanced tumor stage, metastasis, and poor survival. Enforced expression of C1GALT1 was sufficient to enhance cell proliferation, whereas RNA interference– mediated silencing of C1GALT1 was sufficient to suppress cell proliferation in vitro and in vivo.Notably, C1GALT1 attenuation also suppressed hepatocyte growth factor (HGF)–mediated phosphorylation of the MET kinase in hepatocellular carcinoma cells, whereas enforced expression of C1GALT1 enhanced MET phosphorylation. MET blockade with PHA665752 inhibited C1GALT1-enhanced cell viability. In support of these results, we found that the expression level of phospho-MET and C1GALT1 were associated in primary hepatocellular carcinoma tissues. Mechanistic investigations showed that MET was decorated with O-glycans, as revealed by binding to Vicia villosa agglutinin and peanut agglutinin. Moreover, C1GALT1 modified the O-glycosylation of MET, enhancing its HGF-induced dimerization and activation. Together, our results indicate that C1GALT1 overexpression in hepatocellular carcinoma activates HGF signaling via modulation of MET O-glycosylation and dimerization, providing new insights into how O-glycosylation drives hepatocellular carcinoma pathogenesis.

Rehder, and Paolo Boffetta † Molecular Biomarkers Unit, The Biodesign Institute at Arizona State University, Tempe, Arizona 85287, United States ‡ Institute for Translational Epidemiology and Tisch Cancer Institute, Mount Sinai School of Medicine, New York, New York 10029, United States *S Supporting Information ABSTRACT: Dysregulated glycotransferase enzymes in can- cer cells produce aberrant glycanssome of which can help facilitate metastases. Within a cell, individual glycotransferases promiscuously help to construct dozens of unique glycan structures, making it difficult to comprehensively track their activity in biospecimensespecially where they are absent or inactive. Here, we describe an approach to deconstruct glycans in whole biospecimens then analytically pool together resulting monosaccharide-and-linkage-specific degradation products (“glycan nodes”) that directly represent the activities of specific glycotransferases. To implement this concept, a reproducible, relative quantitation-based glycan methylation analysis methodology was developed that simultaneously captures information from N-, O-, and lipid linked glycans and is compatible with whole biofluids and homogenized tissues; in total, over 30 different glycan nodes are detectable per gas chromatography−mass spectrometry (GC-MS) run. Numerous nonliver organ cancers are known to induce the production of abnormally glycosylated serum proteins. Thus, following analytical validation, in blood plasma, the technique was applied to a group of 59 lung cancer patient plasma samples and age/gender/ smoking-status-matched non-neoplastic controls from the Lung Cancer in Central and Eastern Europe (CEE) study to gauge the clinical utility of the approach toward the detection of lung cancer.

  • Deep Evolutionary Analysis Reveals the Design Principles of Fold A
    RESEARCH ARTICLE Deep evolutionary analysis reveals the design principles of fold A glycosyltransferases Rahil Taujale1,2, Aarya Venkat3, Liang-Chin Huang1, Zhongliang Zhou4, Wayland Yeung1, Khaled M Rasheed4, Sheng Li4, Arthur S Edison1,2,3, Kelley W Moremen2,3, Natarajan Kannan1,3* 1Institute of Bioinformatics, University of Georgia, Athens, Georgia; 2Complex Carbohydrate Research Center, University of Georgia, Athens, Georgia; 3Department of Biochemistry and Molecular Biology, University of Georgia, Athens, Georgia; 4Department of Computer Science, University of Georgia, Athens, Georgia Abstract Glycosyltransferases (GTs) are prevalent across the tree of life and regulate nearly all aspects of cellular functions. The evolutionary basis for their complex and diverse modes of catalytic functions remain enigmatic. Here, based on deep mining of over half million GT-A fold sequences, we define a minimal core component shared among functionally diverse enzymes. We find that variations in the common core and emergence of hypervariable loops extending from the core contributed to GT-A diversity. We provide a phylogenetic framework relating diverse GT-A fold families for the first time and show that inverting and retaining mechanisms emerged multiple times independently during evolution. Using evolutionary information encoded in primary sequences, we trained a machine learning classifier to predict donor specificity with nearly 90% accuracy and deployed it for the annotation of understudied GTs. Our studies provide an evolutionary framework for investigating complex relationships connecting GT-A fold sequence, structure, function and regulation. *For correspondence: [email protected] Introduction Competing interests: The Complex carbohydrates make up a large bulk of the biomass of any living cell and play essential authors declare that no roles in biological processes ranging from cellular interactions, pathogenesis, immunity, quality con- competing interests exist.
