The localization of the extracellular matrix glycoprotein laminin was studied using polyclonal anti-laminin antibodies. The laminin patterns of the basement membranes of the muscular epithelial sheath that envelops the ovariole were conspicuously different from those of the basement membrane of the follicular epithelium. In the latter structure laminin was stained in a pattern of parallel strip...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
The interactions between cancer cells and the extracellular matrix (ECM) regulate cancer progression. The beta1C and beta1A integrins, two cytoplasmic variants of the beta1 integrin subfamily, are differentially expressed in prostate cancer. Using gene expression analysis, we show here that the beta1C variant, an inhibitor of cell proliferation, which is down-regulated in prostate cancer, up-re...
Agrin is a large, multidomain heparan sulfate proteoglycan that is associated with basement membranes of several tissues. Particular splice variants of agrin are essential for the formation of synaptic structures at the neuromuscular junction. The binding of agrin to laminin appears to be required for its localization to synaptic basal lamina and other basement membranes. Here, electron microsc...
A bovine BAC clone containing a processed laminin receptor pseudogene (LAMR1P) has been isolated and characterized. A 2,901-bp sequence was produced from the clone, of which 1,187 bp represented seven identifiable exon-like domains, but no intervening sequences. The pseudogene sequence reveals several transversions and transitions, as well as insertions and deletions. A premature stop codon mot...
Background and Objective: It is obviously approved that Fibronectin and Laminin α-5 (LAMA5) expression will change, in some organs of fetuses that their mothers were smoking during pregnancy period. For example, the expression of mentioned proteins in newborns decreases in parenchyma of their lungs. In present study, we evaluated the effects of maternal nicotine exposure on LAMA5 expres...
objective: biomaterial technology, when combined with emerging human induced pluripotent stem cell (hipsc) technology, provides a promising strategy for patient-specific tissue engineering. in this study, we have evaluated the physical effects of collagen scaffolds fabricated at various freezing temperatures on the behavior of hipsc-derived neural progenitors (hipsc-nps). in addition, the coati...
A laminin receptor was isolated from human MG-63 osteosarcoma cells by affinity chromatography on human laminin. The isolated receptor was defined as the alpha 3 beta 1 integrin by immunoprecipitation with subunit-specific antibodies. A previously unclassified laminin-binding integrin from rat cells was shown also to contain the alpha 3 subunit. Both receptors bound to human and mouse laminin i...
