17495450-9	2007	In summary, sera and supernatants from IgG-secreting cell lines from patients with IgAN were characterized by high levels of IgG antibodies with specificity to the Gal-deficient O-linked glycans of IgA1.	o-linked glycans	178-194	IGAN1	Homo sapiens	83-87	
17495449-9	2007	In humans, serum IgA derived from patients with IgAN has aberrant beta3-galactosylation and sialylation on its O-linked glycans of the hinge region.	o-linked glycans	111-127	IGAN1	Homo sapiens	48-52	
17495450-1	2007	The circulating immune complexes in IgA nephropathy (IgAN) are composed of galactose (Gal)-deficient IgA1 bound to IgG or IgA1 antibodies specific for hinge-region O-linked glycans of Gal-deficient IgA1.	o-linked glycans	164-180	IGAN1	Homo sapiens	36-51	
17495450-1	2007	The circulating immune complexes in IgA nephropathy (IgAN) are composed of galactose (Gal)-deficient IgA1 bound to IgG or IgA1 antibodies specific for hinge-region O-linked glycans of Gal-deficient IgA1.	o-linked glycans	164-180	IGAN1	Homo sapiens	53-57	
17712550-2	2007	In IgAN, IgA1 molecules with incompletely galactosylated O-linked glycans in the hinge region (HR) are present in mesangial immunodeposits and in circulating immune complexes.	o-linked glycans	57-73	IGAN1	Homo sapiens	3-7	
17495451-1	2007	IgA1 in the circulation and glomerular deposits of patients with IgA nephropathy (IgAN) is aberrantly glycosylated; the hinge-region O-linked glycans are galactose-deficient.	o-linked glycans	133-149	IGAN1	Homo sapiens	82-86	
11518779-8	2001	Patients with IgAN displayed increased levels of IgA glycoforms exposing sialic acid in alpha2,6 linkage with N-acetylgalactosamine (Neu5Acalpha2,6GalNAc) (P < 0.02) and GalNAc (P < 0.05), indicating truncation of O-linked glycans of IgA1.	o-linked glycans	220-236	IGAN1	Homo sapiens	14-18	
10393701-1	1999	Circulating immune complexes (CICs) isolated from sera of patients with IgA nephropathy (IgAN) consist of undergalactosylated, mostly polymeric, and J chain-containing IgA1 and IgG antibodies specific for N-acetylgalactosamine (GalNAc) residues in O-linked glycans of the hinge region of IgA1 heavy chains.	o-linked glycans	248-264	IGAN1	Homo sapiens	89-93	
9140997-1	1997	BACKGROUND: Reduced galactosylation of the O-linked glycans of the IgA1 hinge region in IgAN has recently been described.	o-linked glycans	43-59	IGAN1	Homo sapiens	88-92
