In order to investigate whether c-Src is involved in carcinogenesis and progression of breast carcinoma, we examined the expression of activated c-Src in tissue sections from surgically resected human breast specimens. First, we confirmed the specificity of the antibody against activated c-Src (Clone 28) using six cell lines established from human breast(More)
BACKGROUND A pathway consisting of bombesin, G-protein coupling receptors (GPCRs), metalloproteases, pro-heparin-binding epidermal growth factor (proHB-EGF), and epidermal growth factor receptor (EGFR) has been reported in prostate cancer cells. The occurrence of HB-EGF shedding from proHB-EGF in this pathway, however, has not been proven directly. In(More)
To clarify the roles of integrin and extracellular matrix (ECM) in the process of non-small cell lung cancer (NSCLC) brain metastasis, we established an in vivo model of brain metastasis of human NSCLC cell line EBC-1/original in athymic mice, and established highly brain metastatic subclone EBC-1/brain and highly bone metastatic subclone EBC-1/bone.(More)
A dextran sulphate gel column removed anti-double-stranded DNA antibodies (anti-dsDNA) selectively, efficiently, and safely from the circulation of a patient with systemic lupus erythematosus (SLE). The mechanism of the removal is thought to be due to cross reactivity of anti-dsDNA with dextran sulphate, which has negatively charged units. Selective removal(More)
The trophoblast, an important component of the mammalian placenta, has several essential biological roles in the maintenance of pregnancy. First, trophoblast cells must attach to the uterine endometrium, and then they must invade to a depth at which the vascular network exists. Here, we investigated the effects of epidermal growth factor (EGF) on alpha2(More)
Osteoclasts which appeared in an early stage of parathyroid hormone (PTH) administration were examined using cytochrome c oxidase activity. In the period of 1-2 hr after intraperitoneal administration of PTH, two types of osteoclasts were observed. The first type had a well-developed ruffled border characterized by deeply infolded extracellular channels,(More)

It has been strongly suggested that the periapical lesion develop as a result of immunopathological response to continuous antigenic stimulation. Bacteria from root canal systems might be most important pathogenesis capable of inducing immunological reactions in periapical tissue. The purpose of this study, therefore, was clarify the immunological(More)
Recently, microwave technology has drawn considerable interests not only in wireless communication systems, but also in wireless power transmissions[1], chemical reactions, and heating systems[2-3]. We are currently exploring the effects of microwave illumination upon plant growth. Different from conventional oil-based greenhouse heating systems, in which(More)
