Amino Acid Sequence

Tyr-Ile-Gly-Ser-Arg

Applicazioni

Tyr-Ile-Gly-Ser-Arg (YIGSR) can be used at the interface between the conjugated polymer and the tissue for the engineering of tissue interface. The product can also be used to study the role of integrins β1, α6, and α3 in promoting type II epithelial differentiation during lung maturation in the fetus.

Azioni biochim/fisiol

Tyr-Ile-Gly-Ser-Arg (YIGSR) is a pentapeptide of the protein laminin that reduces the lung colony formation in mice administered with melanoma cells as well as can block the invasiveness of the cells in vitro. It inhibits the increased expression of endothelial nitric-oxide synthase in primary porcine aortic endothelial cells.
Tyr-Ile-Gly-Ser-Arg is a fragment of domain III of the laminin B1 chain . It is a major receptor binding site in laminin. It competes with laminin for the cell surface receptor. It is an inhibitor of tumor growth and metastasis.

Nota sulla preparazione

Tyr-Ile-Gly-Ser-Arg dissolves in water at 1 mg/ml to yield a clear, colorless solution.

Cell penetrating peptide based gene carriers are notably known for low level of gene transfer. To remedy this, as laminin receptor (LR) has been previously linked to tumor metastasis, the LR-binding domain (YIGSR) as well as a scrambled sequence (SGIYR)

It has been suggested that the mechanical forces acting on endothelial cells may be sensed in part by cell-matrix connections. We therefore studied the role of different matrix proteins, in particular laminin I, on a shear stress-dependent endothelial response, namely

YIGSR peptide anchored pegylated nanospheres (YIGSR-SN) loaded with 5-fluorouracil (5-FU) were investigated for selective and preferential presentation of carrier contents at angiogenic endothelial cells over-expressing laminin receptors on and around tumor tissue and thus for assessing their targetability.

Conformationally constrained mimetics of the laminin cell-adhesion site, YIGSR, are described. The site is the natural antagonist of the integrin-associated laminin receptor 1 (LAMR1) known to mediate metastatic tumor adhesion. The attachment of selected metastatic cell lines toward the constrained

Fibroproliferative airway remodelling, including increased airway smooth muscle (ASM) mass and contractility, contributes to airway hyperresponsiveness in asthma. In vitro studies have shown that maturation of ASM cells to a (hyper)contractile phenotype is dependent on laminin, which can be inhibited
