Neuroblastoma, the second most common solid childhood tumor, can be a highly invasive and metastatic form of cancer. To assess the role of matrix-degrading proteases in this cancer, we have examined the expression of matrix metalloproteinases (MMPs) and their corresponding tissue inhibitors of metalloproteinases (TIMPs) in 7 human neuroblastoma cell lines(More)
Serine proteases and matrix metalloproteinases have been shown to often cooperate in multiple physiological and pathological processes associated with changes in the extracellular matrix (ECM). We have examined the interaction between the plasminogen activator (PA)-plasmin system and matrix metalloproteinases (MMPs) in HT1080 human fibrosarcoma cells(More)
The gene encoding SCG10 was originally isolated as a neuronal marker from neural crest derivatives, implying that this protein may contribute to fundamental neuronal properties. To examine the developmental change of SCG10 expression in brain, immunoblot analysis and in situ hybridization were performed in embryonic day 15 (E15), E19, postnatal day 0 (P0),(More)
The balance between regulatory and inflammatory immune responses is critical to maintain intestinal homeostasis. Furthermore, the nature of the inflammatory response needs to be tailored to the tissue to provide proper protective immunity while preserving host integrity. TLR2 (Toll-like receptor 2) is a unique TLR in that it has been shown to promote(More)
Proteases of the plasminogen-plasminogen activator (PA) system play an important role in cancer metastasis. We have examined the expression of these proteases and their cell surface receptors and inhibitors in neuroblastoma, a tumor that originates in cells of the neural crest and is the second most common solid tumor in children. This analysis was(More)
The change in dielectric properties caused by the destruction of the transport barrier of yeast cells has been investigated. Dielectric measurements were made over the frequency range of 1 kc to 2 Mc by using "leaky" yeast cells prepared by treatments with HgCl(2) or CTAB (cetyl trimethyl ammonium bromide). The Hg-treated cells were observed to give smaller(More)
Differences in scapular morphology between modern humans and the African and lesser apes are associated with the distinct locomotor habits of these groups. However, several traits, particularly aspects of the supraspinous fossa, are convergent between Homo and Pongo-an unexpected result given their divergent locomotor habits. Many morphological assessments(More)
