Cell interactions with extracellular matrices play important roles in morphogenetic processes during embryonic development. Extracellular matrix receptors of the integrin family have been implicated in these steps. Recent studies indicate that a variety of integrins can be differentially expressed during development, consistent with diverse roles for… (More)
Genetic changes occurring in the late stages of colonic tumour progression have received much less attention than those occurring in the early stages. As described in the accompanying paper, SW480 and SW620 cell lines provide a useful model for studying the advanced stages of progression for colon cancer. Comparison of the two cell lines by differential… (More)
To produce parvovirus B19 antigen for diagnostic purposes, partially overlapping segments covering the genes encoding the viral structural proteins VP1 and VP2 were cloned into expression vectors. The constructs were induced in Escherichia coli, resulting in the expression of beta-galactosidase fusion proteins. In immunoblotting experiments with sera from… (More)
BACKGROUND The prostate gland represents a multifaceted system in which prostate epithelia and stroma have distinct physiological roles. To understand the interaction between stroma and glandular epithelia, it is essential to delineate the gene expression profiles of these two tissue types in prostate cancer. Most studies have compared tumor and normal… (More)
Integrin receptors for extracellular matrix molecules are thought to play important roles in morphogenesis since they mediate aspects of embryonic cell adhesion and migration. Using in situ hybridization, the mRNA expression pattern of the beta 5 integrin receptor subunit was examined during murine tooth development, a classical system for studying… (More)
