To understand the genes involved in breast cancer invasion and metastasis, we analyzed a novel candidate metastasis-associated gene, mta1, which was isolated by differential cDNA library screening using the 13762NF rat mammary adenocarcinoma metastatic system. Northern blot analyses showed that the mRNA expression level of the mta1 gene was 4-fold higher in(More)
To understand the genes and gene products involved in breast cancer invasion and metastasis, we previously isolated ten differentially expressed genes by differential cDNA library screening techniques, using the 13762NF rat mammary adenocarcinoma metastatic system. In this study, we further analysed a novel candidate metastasis-associated gene, mta1,(More)
Annexin I is a phospholipid and actin binding protein which may play a role in signal transduction to the cytoskeleton. Previous work reported the differential expression of annexin I mRNA among rat adenocarcinoma cell lines of various metastatic potential (MTLn3, MTLn2, MTC.4: highest to lowest, respectively) (Pencil et al. 1993, Breast Cancer Res Treat,(More)
Differential hybridization was used to isolate genes potentially involved in the process of metastasis. Ten complementary DNAs (cDNAs) that were differentially expressed between a highly metastatic (MTLn3) and a nonmetastatic (MTC.4) line of the rat 13762NF mammary adenocarcinoma were isolated and sequenced. Examination of the EMBL/GenBank database revealed(More)
Secretion of lipid as very low density lipoprotein (VLDL) by isolated hepatocytes was studied in a system in which the cells were exposed to a constant concentration of carbon tetrachloride (CCl4) throughout the duration of the incubation. Inhibition of secretion was characterized in terms of CCl4 concentration and duration of incubation. Half-maximum(More)
A consensus does not exist regarding the nature of mechanisms linking the initial events of CCl4 metabolism to emergence of the classical indices of CCl4 liver cell injury. The possibility that a CCl4-dependent disturbance of intrahepatocellular calcium homeostasis might be a linking mechanism was investigated with isolated hepatocytes in suspension.(More)
Our objective was to investigate the value of postmortem autopsy blood cultures performed with an iodine-subclavian technique relative to the classical method of atrial heat searing and antemortem blood cultures. The study consisted of a prospective autopsy series with each case serving as its own control relative to subsequent testing, and a retrospective(More)
Whole body hyperthermia can be used for the treatment of metastatic cancer and human immunodeficiency virus infections. The therapeutic effects of hyperthermia are dependent upon the actual temperature of the target tissues. Therefore, homogeneous distribution of heat and precise control of temperature gradients is critical. To describe heat distribution(More)
A method for treating isolated hepatocytes with a known and toxicologically meaningful concentration of CCl4 was used to study the effect of the haloalkane on the calcium sequestration capacity of microsomal vesicles derived from the hepatocytes. The essence of the method is to allow a very small volume of CCl4 to come to diffusion equilibrium in a closed(More)
Halogenated hydrocarbons (CCl4, BrCCl3, 1,1-dichloroethylene, bromobenzene) cause a wide spectrum of dysfunction and injury in liver cells. An early effect of CCl4, BrCCl3, and 1,1-dichloroethylene is destruction of the Ca2+-sequestering ability of the endoplasmic reticulum, and it has been suggested that this lesion leads to subsequent disruption of other(More)
