Desmocollins are cadherin-like glycoproteins that are localized in desmosomes. They are thought to play a role in cell adhesion but direct evidence for this is currently unavailable. For this reason we have expressed cDNAs encoding full-length bovine desomocollin type 1a and type 1b in mouse fibroblast (L929) cells. This system has previously been used to(More)
The adhesive core of the desmosome is composed of cadherin-like glycoproteins of two families, desmocollins and desmogleins. Three isoforms of each are expressed in a tissue-specific and developmentally regulated pattern. In bovine nasal epidermis, the three desmocollin (Dsc) isoforms are expressed in overlapping domains; Dsc3 expression is strongest in the(More)
In view of the increasing incidence of primary hepatocellular carcinoma in western Europe and concern that this may in part be related to long-term use of drugs which cause hepatic microsomal enzyme induction, we undertook a comparison of long-term drug use in 105 patients with hepatocellular carcinoma and equal numbers of age and sex-matched patients with(More)
Although the transition from early- to advanced-stage ovarian cancer is a critical determinant of survival, little is known about the molecular underpinnings of ovarian metastasis. We hypothesize that microarray analysis of global gene expression patterns in primary ovarian cancer and metastatic omental implants can identify genes that underlie the(More)
Neurofibrillary tangles and amyloid plaques are considered to be hallmarks of Alzheimer's disease (AD), and the toxic effects of amyloid-beta peptide (A beta) lead to activation of stress-related signaling and neuronal loss. The small heat shock protein Hsp27 is reported to be increased in AD brains and to accumulate in plaques, but whether this represents(More)
Desmocollins are cadherin-like adhesion molecules of desmosomes. We have determined the full cDNA sequence of a murine desmocollin, the homologue of human and bovine type 2 desmocollins (DSC2), and studied its tissue distribution and expression in stratified epithelia. An 8.5 day mouse embryo cDNA library was screened yielding overlapping clones which(More)
Previous studies have suggested that the small heat shock protein, HspB1, has a direct influence on the dynamics of cytoskeletal elements, in particular, filamentous actin (F-actin) polymerization. In this study we have assessed the influence of HspB1 phosphorylation on its interaction(s) with F-actin. We first determined the distribution of endogenous(More)
Desmocollins are cadherin-like glycoproteins involved in cell adhesion and plaque formation in desmosome junctions. Three distinct isoforms, the products of different genes, have been found in bovine tissues. We have reported previously that one of these, DSC3, is expressed only in basal and lower suprabasal layers of stratified epithelia. Using RT-PCR we(More)
The murine Hox-3.3 homeobox containing gene and its Xenopus homologue (XlHbox 1) produce two embryonic transcripts from two distinct promoters located approximately 9 kb apart. In order to begin to characterise one of these promoter regions (PRII), we have sequenced 3 kb of DNA immediately upstream of the transcription start site of the PRII transcript and(More)
Alzheimer's disease is a progressive neurodegenerative disease that has links with other conditions that can often be modified by dietary and life-style interventions. In particular, coconut oil has received attention as having potentially having benefits in lessening the cognitive deficits associated with Alzheimer's disease. In a recent report, we showed(More)
