Abstract
The 37/67-kDa laminin receptor (LAMR/RPSA) was originally identified as a 67-kDa binding protein for laminin, an extracellular matrix glycoprotein that provides cellular adhesion to the basement membrane. LAMR has evolutionary origins, however, as a 37-kDa RPS2 family ribosomal component. Expressed in all domains of life, RPS2 proteins have been shown to have remarkably diverse physiological roles that vary across species. Contributing to laminin binding, ribosome biogenesis, cytoskeletal organization, and nuclear functions, this protein governs critical cellular processes including growth, survival, migration, protein synthesis, development, and differentiation. Unsurprisingly given its purview, LAMR has been associated with metastatic cancer, neurodegenerative disease and developmental abnormalities. Functioning in a receptor capacity, this protein also confers susceptibility to bacterial and viral infection. LAMR is clearly a molecule of consequence in human disease, directly mediating pathological events that make it a prime target for therapeutic interventions. Despite decades of research, there are still a large number of open questions regarding the cellular biology of LAMR, the nature of its ability to bind laminin, the function of its intrinsically disordered C-terminal region and its conversion from 37 to 67 kDa. This review attempts to convey an in-depth description of the complexity surrounding this multifaceted protein across functional, structural and pathological aspects.

Abstract
We have demonstrated previously that kinin-free high molecular weight kininogen, its domain 5 (D5H, Gly402-Lys502), and peptides derived from D5H inhibited vitronectin-mediated migration and invasion of cancer cells in vitro (Kamiyama, F., Maeda, T., Yamane, T., Li, Y. H., Ogikubo, O., Otsuka, T., and Ohkubo, I. (2001) Biochem. Biophys. Res. Commun. 288, 975-980). In this study, we found that the amino acid sequence His-Gly-Lys (HGK) in D5H is the core motif for inhibition of adhesion and invasion of MDA-MB-231 cells in vitro. P-5m (484GHGKHKNK491, Gly484-Lys491), an octapeptide including the HGK motif derived from D5H, and HGK, a tripeptide, inhibited both cell adhesion and invasion in vitro. However, an octapeptide designated P-5m (K487R), in which Lys487 was changed to Arg, did not inhibit either cell adhesion or invasion, and peptides HGR and HGG also had no inhibitory effect. Recombinant GST-D5H expressed in Escherichia coli had a stronger inhibitory effect on cell adhesion and invasion in vitro than did GST-D5H (K487R) in which Lys487 was changed to Arg. Furthermore, P-5m (Gly484-Lys491) peptide clearly suppressed lung metastasis in mice experimentally induced by using B16-F10 cells, but P-5m (G487R) had no effect. These data strongly indicate that both the HGK motif and lysine residue (Lys487) play essential roles in inhibition of cell adhesion and invasion in vitro and in prevention of metastasis of cancer cells in vivo. We tried to identify the HGK motif binding protein on the surface of cancer cells. A 95-kDa surface biotin-labeled membrane protein was specifically detached from GST-D5H by P-5 (His479-Lys493) peptide but not by P-1 (Gly402-Lys420) peptide originating from the N-terminal region of D5H.

Abstract
Considering that chronic elevation of shear stress results in remodeling of the vasculature, we analyzed whether mechanical load could mediate basic fibroblast growth factor (bFGF) release and whether bFGF would act as mediator of shear stress-induced endothelial proliferation and differentiation. Supernatant media of shear stress-exposed endothelial cells (EC) contained significantly higher amounts of bFGF than medium from static cells. Released bFGF was fully intact with regard to its function as an inductor of proliferation and differentiation. Shear stress-conditioned media induced capillary-like structure formation, whereas static control medium did not. Likewise, only shear stress-conditioned medium induced proliferation of serum starved EC. Both capillary-like structure formation and proliferation could be inhibited by neutralization of bFGF or its receptor. The release of bFGF was subject to specific, integrin-mediated control, since inhibition of alpha(v)beta(3) integrin prevented it, whereas inhibition of alpha(5)beta(1) integrin had no effect. We conclude that shear stress induces the release of bFGF from EC in a tightly controlled manner. The release is dependent on specific cell-matrix interactions via alpha(v)beta(3) integrins. The effects on cell proliferation and differentiation suggest that release of bFGF is functionally significant and may represent a necessary initial step in adaptive remodeling processes induced by shear stress.

Abstract
The strength of adhesion of NG108-15 cells to glass substrates modified with adsorbed proteins (laminin and poly-ornithine) or modified with covalently bound peptides (tri-ornithine and Tyr-Ile-Gly-Ser-Arg) was quantitatively assessed, by determining the shear stresses necessary to denude the cells from substrates using a spinning disk device. The shear stresses required to detach NG108-15 cells from glass modified with either adsorbed poly-ornithine or with both poly-ornithine and laminin were significantly (P < 0.05) higher than the shear stresses required to detach the cells from plain glass substrates. Covalent surface modifications resulted in higher strengths of NG108-15 adhesion than were exhibited on surfaces modified with adsorbed proteins. NG108-15 cell adhesion strength was maximal on surfaces covalently modified with only amine groups (without any peptides or proteins). These results indicate that general (i.e., not necessarily receptor-specific) surface modification strategies, which increase the net surface charge of a substrate, will elicit strong adhesion of NG108-15 cells.

Abstract
Agarose hydrogel scaffolds were engineered to stimulate and guide neuronal process extension in three dimensions in vitro. The extracellular matrix (ECM) protein laminin (LN) was covalently coupled to agarose hydrogel using the bifunctional cross-linking reagent 1,19- carbonyldiimidazole (CDI). Compared to unmodified agarose gels, LN-modified agarose gels significantly enhanced neurite extension from three-dimensionally (3D) cultured embryonic day 9 (E9) chick dorsal root ganglia (DRGs), and PC 12 cells. After incubation of DRGs or PC 12 cells with YIGSR peptide or integrin beta1 antibody respectively, the neurite outgrowth promoting effects in LN-modified agarose gels were significantly decreased or abolished. These results indicate that DRG/PC 12 cell neurite outgrowth promoting effect of LN-modified agarose gels involves receptors for YIGSR/integrin beta1 subunits respectively. 1,2-bis(10, 12-tricosadiynoyl)-sn-glycero-3-phosphocholine (DC(8,9)PC)-based lipid microcylinders were loaded with nerve growth factor (NGF), and embedded into agarose hydrogels. The resulting trophic factor gradients stimulated directional neurite extension from DRGs in agarose hydrogels. A PC 12 cell-based bioassay demonstrated that NGF-loaded lipid microcylinders can release physiologically relevant amounts of NGF for at least 7 days in vitro. Agarose hydrogel scaffolds may find application as biosynthetic 3D bridges that promote regeneration across severed nerve gaps.

Abstract
Monoclonal nonspecific suppressor factor (MNSF), a lymphokine produced by murine T cell hybridoma, possesses pleiotrophic antigen-nonspecific suppressive functions. A cDNA clone encoding MNSF-beta, an isoform of the MNSF, has been isolated and characterized. MNSF-beta cDNA encodes a fusion protein consisting of a ubiquitin-like segment (Ubi-L) and ribosomal protein S30. Ubi-L appears to be cleaved from the ribosomal protein and released extracellularly in association with T cell receptor-like polypeptide. In the current study we have characterized the biochemical nature of the Ubi-L receptor on D.10 G4.1, a murine T helper clone type 2. Biotinylated Ubi-L bound preferentially to concanavalin A-stimulated but not to unstimulated D.10 cells. Detergent-extracted membrane proteins were applied to an immobilized Ubi-L column. SDS-polyacrylamide gel electrophoresis of eluted fraction revealed a band of Mr = 82,000. Biotinylated Ubi-L specifically recognized this band, confirming that the 82-kDa protein is the Ubi-L receptor. A complex of Mr = 90,000 was visualized by immunoprecipitation of 125I-Ubi-L cross-linked to the purified receptor followed by SDS-polyacrylamide gel electrophoresis and autoradiography. In addition, a 105-kDa protein was coimmunoprecipitated by anti-Ubi-L receptor (82-kDa polypeptide) antibody, indicative of the association of this protein with the Ubi-L receptor complex. Amino acid sequence analysis of the 82-kDa polypeptide revealed that the Ubi-L receptor may be a member of a cytokine receptor family.

Abstract
We have examined the mechanism of signaling by the 67 kDa YIGSR binding protein of laminin and its properties in neuroblastoma cells. Ligand displacement analysis showed that the interaction with the C(YIGSR)3-NH2 peptide amide is of intermediate affinity (1.5 x 10[-7] M). Cross-linking experiments with sulfo-MBS detected an additional protein with a molecular mass of 116 kDa that binds the YIGSR sequence. Incubation of neuroblastoma cells with C(YIGSR)3-NH2 peptide amide or antibody directed against the 67 kDa laminin binding protein induces tyrosine phosphorylation of proteins with a molecular mass ranging from 115 to 130 kDa and another heterogeneous protein group of 32 kDa.

Abstract
Apical ectodermal ridge (AER)-mesoderm interaction is important for morphogenesis in the developing chick limb bud. Genes whose expression is dependent upon the presence of AER, are likely to play important roles in the AER-mesoderm interaction. We report here the gene expression pattern of the chick homolog of the 67 kDa laminin binding protein (LBP), which is a non-integrin laminin receptor whose function relates to cell attachment, spreading, and polarization. Northern analysis showed that a single 1.4 kb transcript exists in stage 20 limb buds and which is dramatically reduced 24 hr after removal of AER. In situ hybridization analysis revealed that the chick 67 kDa laminin binding protein gene (cLbp) was expressed in the mesodermal region overlapping the Msx1-expressing domain and in the AER in early stage limb buds. Expression in the mesoderm was gradually restricted to the distal region underneath the AER as development proceeds. The expression in the limb mesoderm could be induced by local application of FGF-2 which could thus mimic the AER functions. These results indicated that the expression of cLbp depends on AER signals and that the 67 kDa non-integrin receptor binding to laminin plays a role in the AER-mesoderm interaction.

Abstract
The laminins are a family of extracellular matrix glycoproteins expressed throughout developing neural tissues. The laminins are potent stimulators of neurite outgrowth in vitro for a variety of cell types, presumably reflecting an in vivo role in stimulating axon outgrowth. In recent years, the laminins have been shown to occur in several distinct isoforms; currently, the precise functional differences between the laminin variants are not well understood. A variety of neuronal surface receptors have been identified for one laminin isoform, laminin-1. These receptors include several members of the integrin family, as well as non-integrin laminin-binding proteins such as LBP-110, the 67 kDa laminin-receptor, alpha-dystroglycan, and beta 1,4 galactosyltransferase. Little is currently known about receptors for other laminin isoforms.
