Retinoic-Acid-Induced Downregulation of the 67 KDa Laminin Receptor Correlates with Reduced Biological Aggressiveness of Human Neuroblastoma Cells
2012
Neuroblastoma is a common tumor of the childhood arising from embryonal sympathetic neural cell precursors. Despite of the improved therapeutic strategies, the survival rate of high-risk neuroblastoma patients is poor. Although complete clinical remissions can be achieved, relapse is relatively frequent, indicating a role for the persistence of the minimal residual disease (for review, Maris, 2010). Treatments with derivatives of retinoic acid (RA), the biologically active form of vitamin A, produce significant improvements on the therapy of high-risk neuroblastoma patients, when used together with intensive multimodal therapies (Reynolds et al., 2003, for review). Despite some controversy …
Adhesion of 8701-BC breast cancer cells to type V collagen and 67 kDa receptor
1992
Ductal infiltration carcinomas (d.i.c.) of the breast are potentially highly metastatic tumours, associated with drastic alterations of the architecture and molecular composition of the extracellular matrix at the tumour-host interface. 8701-BC, a recently characterized cell line, isolated from primary d.i.c., was used to study different aspects of tumor cell-substratum interactions. Since type V collagen deposition is augmented in d.i.c. we have examined the ability of 8701-BC cells to interact with this collagen species. We have found that cell binding to type V collagen was mediated by protein homologous to the 67 kDa laminin receptor (67-R). This conclusion is substantiated by the follo…
