Abstract
Background Changes in protein glycosylation have been reported in various diseases, including cancer; however, the consequences of altered glycosylation in meningiomas remains undefined. We established two benign meningioma cell lines-SUT-MG12 and SUT-MG14, WHO grade I-and demonstrated the glycan and glycosyltransferase profiles of the mucin-type O-linked glycosylation in the primary benign meningioma cells compared with two malignant meningioma cell lines-HKBMM and IOMM-Lee, WHO grade III. Changes in O-linked glycosylation profiles in malignant meningiomas were proposed. Methods Primary culture technique, morphological analysis, and immunocytochemistry were used to establish and characterize two benign meningioma cell lines. The glycan profiles of the primary benign and malignant meningiomas cell lines were then analyzed using lectin cytochemistry. The gene expression of O-linked glycosyltransferases, mucins, sialyltransferases, and fucosyltransferases were analyzed in benign and malignant meningioma using the GEO database (GEO series GSE16581) and quantitative-PCR (qPCR). Results Lectin cytochemistry revealed that the terminal galactose (Gal) and N-acetyl galactosamine (GalNAc) were highly expressed in primary benign meningioma cells (WHO grade I) compared to malignant meningioma cell lines (WHO grade III). The expression profile of mucin types O-glycosyltransferases in meningiomas were observed through the GEO database and gene expression experiment in meningioma cell lines. In the GEO database, C1GALT1-specific chaperone (COSMC) and mucin 1 (MUC1) were significantly increased in malignant meningiomas (Grade II and III) compared with benign meningiomas (Grade I). Meanwhile, in the cell lines, Core 2 β1,6-N-acetylglucosaminyltransferase-2 (C2GNT2) was highly expressed in malignant meningiomas. We then investigated the complex mucin-type O-glycans structures by determination of sialyltransferases and fucosyltransferases. We found ST3 β-galactoside α-2,3-sialyltransferase 4 (ST3GAL4) was significantly decreased in the GEO database, while ST3GAL1, ST3GAL3, α1,3 fucosyltransferases 1 and 8 (FUT1 and FUT8) were highly expressed in malignant meningioma cell lines-(HKBMM)-compared to primary benign meningioma cells-(SUT-MG12 and SUT-MG14). Conclusion Our findings are the first to demonstrate the potential glycosylation changes in the O-linked glycans of malignant meningiomas compared with benign meningiomas, which may play an essential role in the progression, tumorigenesis, and malignancy of meningiomas.

Abstract
Objective This study aimed to investigate the expression of O-linked
glycoprotein glycans in tissue of patients with cholangiocarcinoma compared
with adjacent normal tissue. Methods Sixty patients with cholangiocarcinoma were included in the study.
Permethylated O-linked glycans from intrahepatic
cholangiocarcinoma tissue and adjacent normal tissue were analyzed using
nano-spray ionization-linear ion trap mass spectrometry. Histochemistry of
peanut agglutinin lectin was used for detection and localization of
galactose (Gal) 1, N-acetyl-galactosamine (GalNAc) 1. Results O-linked glycans from patients with cholangiocarcinoma were
composed of di- to hexa-saccharides with a terminal galactose and sialic
acids (N-acetylneuraminic acid [NeuAc]). A total of eight
O-linked glycan structures were detected. Gal1GalNAc1 and
Gal2 N-acetyl-glucosamine 1 GalNAc1 expression was significantly higher in
tissue from patients with cholangiocarcinoma compared with adjacent normal
tissue, while NeuAc1Gal1GalNAc1 expression was significantly lower. High
Gal1GalNAc1 expression was significantly associated with the late stage of
cholangiocarcinoma (stages II–IV), lymphatic invasion, and vascular
invasion. Conclusion Our study shows expression of O-linked glycans in
progression of cholangiocarcinoma and highlights the association of
Gal1GalNAc1 with lymphatic and vascular invasion of cholangiocarcinoma.

Abstract
Erythropoietin (Epo) and its receptor (EpoR), critical for erythropoiesis, are expressed in the nervous system. Prior to death in utero because of severe anemia EpoR-null mice have fewer neural progenitor cells, and differentiated neurons are markedly sensitive to hypoxia, suggesting that during development Epo stimulates neural cell proliferation and prevents neuron apoptosis by promoting oxygen delivery to brain or by direct interaction with neural cells. Here we present evidence that neural progenitor cells express EpoR at higher levels compared with mature neurons; that Epo stimulates proliferation of embryonic neural progenitor cells; and that endogenous Epo contributes to neural progenitor cell proliferation and maintenance. EpoR-null mice were rescued with selective EpoR expression driven by the endogenous EpoR promoter in hematopoietic tissue but not in brain. Although these mice exhibited normal hematopoiesis and erythrocyte production and survived to adulthood, neural cell proliferation and viability were affected. Embryonic brain exhibited increased neural cell apoptosis, and neural cell proliferation was reduced in the adult hippocampus and subventricular zone. Neural cells from these animals were more sensitive to hypoxia/glutamate neurotoxicity than normal neurons in culture and in vivo. These observations demonstrate that endogenous Epo/EpoR signaling promotes cell survival in embryonic brain and contributes to neural cell proliferation in adult brain in regions associated with neurogenesis. Therefore, Epo exerts extra-hematopoietic function and contributes directly to brain development, maintenance, and repair by promoting cell survival and proliferation independent of insult, injury, or ischemia.

Abstract
Multi-tissue erythropoietin receptor (EPO-R) expression provides for erythropoietin (EPO) activity beyond its known regulation of red blood cell production. This review highlights the role of EPO and EPO-R in brain development and neuroprotection. EPO-R brain expression includes neural progenitor cells (NPC), neurons, glial cells and endothelial cells. EPO is produced in brain in a hypoxia sensitive manner, stimulates NPC proliferation and differentiation, and neuron survival, and contributes to ischemic preconditioning. Mice lacking EPO or EPO-R exhibit increased neural cell apoptosis during development before embryonic death due to severe anemia. EPO administration provides neural protection in animal models of brain ischemia and trauma, reducing the extent of injury and damage. Intrinsic EPO production in brain and EPO stimulation of endothelial cells contribute to neuroprotection and these are of particular importance since only low levels of EPO appear to cross the blood-brain barrier when administered at high dose intravenously. The therapeutic potential of EPO for brain ischemia/trauma and neurodegenerative diseases has shown promise in early clinical trial and awaits further validation.

Abstract
There is evidence that developing thalamic cells become dependent for their survival on the integrity of their afferent and/or efferent connections, which may provide required levels of neural activity and/or essential neurotrophic factors. These connections develop in the second half of gestation in mice and, during this time (embryonic days 17-19), isolated thalamic cells either grown as explants or dissociated from each other lose their ability to survive. Here we show that the loss of viability of explants, but not of dissociated cells, is delayed if the cultures are treated with depolarizing stimuli. The survival of dissociated thalamic cells is promoted by culture medium conditioned by thalamic explants grown with depolarizing stimuli, indicating that the effect of depolarization involves trophic factors released by thalamic cells. This survival promoting effect is found prenatally, but not postnatally, and is prevented by the neurotrophin blocker K252a. Culture medium conditioned by cortex also promotes the survival of thalamic cells and this effect does occur postnatally. These findings suggest that diffusible factors, possibly members of the neurotrophin family, and depolarizing stimuli regulate thalamic cell survival before birth, but trophic support from cortex becomes crucial after birth. This culture model may provide a means of investigating the mechanisms of thalamic cell survival during development.

Abstract
Many neurons die as the normal brain develops. How this is regulated and whether the mechanism involves neurotrophic molecules from target cells are unknown. We found that cultured neurons from a key forebrain structure, the dorsal thalamus, develop a need for survival factors including brain-derived neurotrophic factor (BDNF) from their major target, the cerebral cortex, at the age at which they innervate it. Experiments in vivo have shown that rates of dorsal thalamic cell death are reduced by increasing cortical levels of BDNF and are increased in mutant mice lacking functional BDNF receptors or thalamocortical projections; these experiments have also shown that an increase in the rates of dorsal thalamic cell death can be achieved by blocking BDNF in the cortex. We suggest that the onset of a requirement for cortex-derived neurotrophic factors initiates a competitive mechanism regulating programmed cell death among dorsal thalamic neurons.

Abstract
The cerebral cortex develops from the dorsal telencephalon, at the anterior end of the neural tube. Neurons are generated by cell division at the inner surface of the telencephalic wall (in the ventricular zone) and migrate towards its outer surface, where they complete their differentiation. Recent studies have suggested that the transcription factor Pax6 is important for regulation of cell proliferation, migration and differentiation at various sites in the CNS. This gene is widely expressed from neural plate stage in the developing CNS, including the embryonic cerebral cortex, where it is required for radial glial cell development and neuronal migration. We report new findings indicating that, in the absence of Pax6, proliferative rates in the early embryonic cortex are increased and the differentiation of many cortical cells is defective. A major question concerns the degree to which cortical defects in the absence of Pax6 are a direct consequence of losing the gene function from defective cells themselves, rather than being secondary to abnormalities in other cells. Cortical defects in the absence of Pax6 become much more pronounced later in cortical development, and we propose that many result from a compounding of abnormalities in proliferation and differentiation that first appear at the onset of corticogenesis.

Abstract
The effect of melatonin administration on nerve growth factor (NGF) was studied in the submandibular glands of adult Swiss male mice. Melatonin injection, at 1 microg daily for 30 days, resulted in an increase in the NGF content as detected by immunohistochemistry. The submandibular gland weight and the area of the granular convoluted tubules, which contained NGF, were also increased significantly. These effects were not observed when the dose of melatonin was increased to 10 and 50 microg daily. None of the melatonin treatments used influenced the weights or histology of the testes or seminal vesicles of the mice. The results suggest that melatonin, at physiological concentrations, directly regulates NGF synthesis in the mouse submandibular gland.
