With the exception of the divergent β4 and β8 chains, the integrin β subunit cytoplasmic domains are short and highly conserved sequences. Consensus motifs are found among the different cytoplasmic β chains. Experiments using chimeric receptors demonstrated that the 47 amino acids of the β1 subunit cytoplasmic domain contain sufficient information to target integrins to adhesion plaques. Three ...
Integrins are heterodimeric extracellular matrix receptors that are essential for the proper development of the vertebrate nervous system. We report here that selective loss of integrin β1 in excitatory neurons leads to reductions in the size and complexity of hippocampal dendritic arbors, hippocampal synapse loss, impaired hippocampus-dependent learning, and exaggerated psychomotor sensitivity...
Here we show that dynamin 2 (Dnm2) is essential for angiogenesis in vitro and in vivo. In cultured endothelial cells lacking Dnm2, vascular endothelial growth factor (VEGF) signaling and receptor levels are augmented whereas cell migration and morphogenesis are impaired. Mechanistically, the loss of Dnm2 increases focal adhesion size and the surface levels of multiple integrins and reduces the ...
Loss-of-function mutations in the gene encoding the integrin co-activator kindlin-1 cause Kindler syndrome. We report a novel kindlin-1-deficient keratinocyte cell line derived from a Kindler syndrome patient. Despite the expression of kindlin-2, the patient's cells display several hallmarks related to reduced function of β1 integrins, including abnormal cell morphology, cell adhesion, cell spr...
OBJECTIVE To comparatively investigate the expression of several integrins in specimens of human bone metastases and degenerative bone tissue. METHODS Degenerative cancellous tissue was obtained from a sample of human degenerative spine. Thirteen human specimens were obtained from metastatic spine tumors, whose primary cancer was colon cancer (n=3), hepatocellular cancer (n=3), lung cancer (n...
Fucoxanthinol (FxOH), the main metabolite of marine carotenoid fucoxanthin, exerts anti-cancer effects. However, fragmentary information is available on growth-inhibiting effects FxOH breast cancer (BC). We investigated human BC cells (MCF-7 and MDA-MB-231 cells), underlying mechanisms, differently from previous studies, by using comprehensive transcriptome analysis. The molecular mechanisms we...
The prototypic acute phase reactant C-reactive protein (CRP) is not only a marker but also a potential contributor to inflammatory diseases. CRP exists as the circulating native, pentameric CRP (pCRP) and the monomeric isoform (mCRP), formed as a result of a dissociation process of pCRP. mCRP is highly pro-inflammatory, but pCRP is not. The mechanism of pro-inflammatory action of mCRP is unclea...
It was recently demonstrated the penfluridol inhibited breast tumor growth and metastasis and this was associated with downregulation of α6- and β4-integrins. In this study, we observed the penfluridol induced reactive oxygen species (ROS) and this was the primary mechanism of action. Penfluridol-mediated growth inhibition, induction of apoptosis, and inhibition of breast cancer cell migration ...
