Clioquinol (CQ) was associated with cases of transient global amnesia and with the neurodegenerative syndrome subacute myelo-optico-neuropathy (SMON) in humans. However, CQ forms lipophilic chelates with cations and has the potential as a scientific and clinical tool used for selective modulation of histochemically reactive zinc pools. The relationship(More)
Anoikis, apoptosis because of loss of cell anchorage, is crucial for tissue homeostasis. Fibronectin not only provides a scaffold for cell anchorage but also harbors a cryptic antiadhesive site capable of inducing β1-integrin inactivation. In this study, this cryptic antiadhesive site is implicated in spontaneous induction of anoikis. Nontransformed(More)
The acquisition of drug resistance mediated by the interaction of tumor cells with the extracellular matrix (ECM), commonly referred to as cell adhesion-mediated drug resistance (CAM-DR), has been observed not only in hematopoietic tumor cells but also in solid tumor cells. We have previously demonstrated that a 22-mer peptide derived from fibronectin,(More)
Several attempts have been made to classify the cementum-producing tumors, the latest being that proposed by a WHO group (1970) which is used here. The cementifying fibroma is one of these. The lesion is proliferative of fibrous tissue associated with cemental calcification that occurs central or peripheral to the jaw bones. The purpose of the present study(More)
To investigate the adrenal toxicity of a novel inhibitor of acyl-coenzyme A:cholesterol O-acyltransferase, compound X (CX), histopathological examinations, fat staining, adrenal cholesterol measurement, blood biochemistry, plasma corticosterone and ACTH measurement, ACTH-stimulation assay, and adrenal gene-expression analyses were done in rats in(More)
