Megjegyzések:	Background: A number of human inflammatory diseases and tumors have been shown to cause alterations in the glycosylation pattern of plasma proteins in a specific manner. These highly variable and versatile post-translational modifications finetune protein functions by influencing sorting, folding, enzyme activity and subcellular localization. However, relatively little is known about regulatory factors of this procedure and about the accurate causative connection between glycosylation and disease. Objective: The aim of the present study was to investigate whether certain single nucleotide polymorphisms (SNPs) in genes encoding glycosyltransferases and glycosidases could be associated with elevated risk for chronic obstructive pulmonary disease (COPD) and lung adenocarcinoma. Methods: A total of 32 SNPs localized in genes related to N-glycosylation were selected for the association analysis. Polymorphisms with putative biological functions (missense or regulatory variants) were recruited. SNPs were genotyped by a TaqMan OpenArray platform. A single base extension-based method in combination with capillary gel electrophoresis was used for verification. Results: The TaqMan OpenArray approach provided accurate and reliable genotype data (global call rate: 94.9%, accuracy: 99.6%). No significant discrepancy was detected between the obtained and expected genotype frequency values (Hardy?Weinberg equilibrium) in the healthy control sample group in case of any SNP confirming reliable sampling and genotyping. Allele frequencies of the rs3944508 polymorphism localized in the 3' UTR of the MGAT5 gene significantly differed in the sample groups compared. Conclusion: Our results suggest that the rs34944508 SNP might modulate the risk for lung cancer by influencing the expression of MGAT5. This enzyme catalyzes the addition of N-acetylglucosamine (GlcNAc) in beta 1-6 linkage to the alpha-linked mannose of biantennary N-linked oligosaccharides, thus, increasing branching that is the characteristic of invasive malignancies.

Megjegyzések:	AIMS: To apply capillary electrophoresis with laser induced fluorescence detection (CE-LIF) to identify the N-glycosylation structures of serum and saliva IgA from healthy controls and patients with malignant hematological diseases having cytostatic treatment induced mild oral mucosal lesions. BACKGROUND: Altered N-glycosylation of body fluid glycoproteins can be effective indicators of most inflammatory processes. Immunoglobulin A (IgA) is the second highest abundant of the immunoglobulins and has a major role in the immune-defense against potential pathogen attacks. While IgA is abundant in serum, secretory immunoglobulin A (sIgA) is one of the most prevalent proteins in mucosal surfaces such as in saliva. OBJECTIVE: Our aim was to investigate the changes of IgA glycosylation in serum and saliva as a response to an administered cytostatic treatment in patients with malignant hematological disorders. MATERIALS: Capillary electrophoresis with laser induced fluorescent detection (CE-LIF) was used to analyze the N-glycosylation profiles of Z(IgA1) partitioned immunoglobulin A in pooled serum and saliva of 10 control subjects and 8 patients with malignant hematological diseases having cytostatic treatment induced mild oral mucosal lesions. RESULTS: Eight of 31 and four of 38 N-glycans in serum and saliva, respectively, showed significant (p<0.05) differences upon comparison to the control group. Thirteen glycans were present in the saliva but not in the serum, on the other hand six structures were found in the serum samples not present in the saliva. CONCLUSION: The developed Z(IgA1) partitioning and the high resolution CE-LIF based glyocoanalytical methods provided an efficient and sensitive workflow to detect and monitor IgA glycosylation alterations in serum and saliva with the scope for widespread molecular medicinal use.
