Abstract
Structural changes of glycans are observed in different (patho)physiological conditions. Human placental membrane (glyco)proteins were isolated from the first and third trimester placentas of mothers at different ages. By using lectin microarray, we demonstrated that the placental membrane N-glycome contains several N-glycan groups: high mannose, asialylated and sialylated biantennary moieties, bisected, core fucosylated, fucosylated at other positions (bearing terminal and/or antennary Fuc), α2-6 and α2-3 sialylated structures. Employing MALDI-TOF MS enabled identification of over sixty different N-glycan structures in all samples, with 17 moieties exceeding the relative abundance of 2%. The major MS peaks originated from: 1) biantennary complex type N-glycan with a bisecting GlcNAc residue and 2) a core Fuc paucimannosidic and high mannose type structures M3-M9. Age of mothers and the stage of placental development affected N-glycome. The work presented in this article is the first comprehensive mass spectrometric study of the N-glycome of human placental membrane proteins. Our results may be seen as the baseline which can serve for future MALDI MS profiling of the placental membrane N-glycome in different pathophysiological conditions.

Abstract
Posttranslational modifications (PTM) which accompany pathological conditions affect protein structure, characteristics and modulate its activity. Glycosylation is one of the most frequent PTM influencing protein folding, localisation and function. Hypertension is a common gestational complication, which can lead to foetal growth restriction (IUGR) and even to foetal or maternal death. In this work we focused on the impact of preeclampsia complicated with IUGR on placental membrane N-glycome. Results have shown that preeclampsia reduced fucosylation of placental glycans, increased the appearance of paucimannosidic and mannosidic structures with lower number of mannose residues and decreased the amount of glycans with more mannose residues. Since preeclampsia is tightly connected to IUGR, glycosylation changes were investigated also on the functional membrane receptors responsible for growth: insulin receptor and the type 1 insulin-like growth factor receptor (IR and IGF1R). It was found that IR present in the IUGR placenta contained significantly less α2,6-Sia. Therefore, glycans on placental membranes alter due to preeclampsia, but changes seen at the level of the entire N-glycome may be different from the changes detected at the level of a specific glycoprotein. The difference recorded due to pathology in one membrane molecule (IR) was not found in another homologous molecule (IGF1R). Thus, besides studying the glycosylation pattern of the entire placental membrane due to preeclampsia, it is inevitable to study directly glycoprotein of interest, as no general assumptions or extrapolations can be made.

Abstract
Aberrant changes in specific glycans have been shown to be associated with immunosurveillance, tumorigenesis, tumor progression and metastasis. In this study, the N-glycan profiling of membrane proteins from human breast cancer cell lines and tissues was detected using modified DNA sequencer-assisted fluorophore-assisted carbohydrate electrophoresis (DSA-FACE). The N-glycan profiles of membrane proteins were analyzed from 7 breast cancer cell lines and MCF 10A, as well as from 100 pairs of breast cancer and corresponding adjacent tissues. The results showed that, compared with the matched adjacent normal tissue samples, two biantennary N-glycans (NA2 and NA2FB) were significantly decreased (p <0.0001) in the breast cancer tissue samples, while the triantennary glycan (NA3FB) and a high-mannose glycan (M8) were dramatically increased (p = 0.001 and p <0.0001, respectively). Moreover, the alterations in these specific N-glycans occurred through the oncogenesis and progression of breast cancer. These results suggested that the modified method based on DSA-FACE is a high-throughput detection technology that is suited for analyzing cell surface N-glycans. These cell surface-specific N-glycans may be helpful in recognizing the mechanisms of tumor cell immunologic escape and could be potential targets for new breast cancer drugs.
