Chick embryo retinal ganglion cell (RGC) axons grow to the optic tectum along a stereotyped route, as if responding to cues distributed along the pathway. We showed previously that, in culture, RGCs from embryonic Day 6 retina are responsive to the neurite-promoting effects of the extracellular matrix glycoprotein laminin and that this response is lost by(More)
The decisive role played by adhesive interactions between neuronal processes and the culture substrate in determining the form and extent of neurite outgrowth in vitro has greatly influenced ideas about the mechanisms of axonal growth and guidance in the vertebrate nervous system. These studies have also helped to identify adhesive molecules that might be(More)
BACKGROUND Whereas the antimicrobial peptides hBD-2 and -3 are related to inflammation, the constitutively expressed hBD-1 might function as 8p tumour suppressor gene and thus play a key role in control of transcription and induction of apoptosis in malignant epithelial tumours. Therefore this study was conducted to characterise proteins involved in cell(More)
BACKGROUND Periodontitis is an inflammatory disease caused by pathogenic microorganisms, such as Porphyromonas gingivalis, and characterized by the destruction of the periodontium. Obese individuals have an increased risk for periodontitis and show decreased serum levels of adiponectin. This in-vitro study was established to examine whether adiponectin(More)
Because of the infrequence of salivary gland tumours and their complex histopathological diagnosis it is still difficult to exactly predict their clinical course by means of recurrence, malignant progression and metastasis. In order to define new proliferation associated genes, purpose of this study was to investigate the expression of human α-defensins(More)
Myelin-deficient mutant mice, such as shiverer, can provide information about the normal mechanisms involved in myelination. The shiverer mouse carries a recessive, autosomal mutation resulting in an extreme deficiency in central myelin, and the small amount of myelin present is poorly compacted; the peripheral myelin, however, appears essentially normal.(More)
The preceding discussion documents the diverse ways in which monoclonal antibodies have contributed to neuroscience research. They provide highly specific reagents to membrane-associated proteins, such as pumps, channels, receptors, and cell-adhesion molecules, that are useful for purifying these proteins, studying their structures at high resolution, and(More)
Adipokines, such as nicotinamide phosphoribosyltransferase (NAMPT), are molecules, which are produced in adipose tissue. Recent studies suggest that NAMPT might also be produced in the tooth-supporting tissues, that is, periodontium, which also includes the gingiva. The aim of this study was to examine if and under what conditions NAMPT is produced in(More)
Small cell lung carcinomas (SCLCs) represent highly aggressive tumors with an overall five-year survival rate in the range of 5 to 10%. Here, we show that four out of five SCLC cell lines reversibly develop a neuron-like phenotype on extracellular matrix constituents such as fibronectin, laminin or thrombospondin upon staurosporine treatment in an(More)
The objective of this study was to investigate gene expression levels of oncogenic relevant human defensins and their impact on proliferation rates of 29 cell lines derived from main types of different tumor origins. Differential gene expression analysis of human defensins was performed by real-time PCR experiments. The proliferation rate of tumor cells(More)
