流式细胞术分析: 一个代表性批次产品已在SKOV3、OVCAR3和IGROV1人卵巢癌细胞中检测到αvβ3的表达。在用来自小鼠顶叶卵黄囊的SPARC(酸性的分泌蛋白,富含半胱氨酸)处理后,其表面表达被下调(Said, N., et al. (2007).Am. J. Pathol.170(3):1054–1063)。 流式细胞术分析:一个代表性的批次产品检测到玻尿酸受体(VnR)复合体在与αv和野生型β3或Glanzmanns′血友病伴Asp119Tyr突变(β3cam)的Cam变体共转染的CHO细胞的表面表达(Loftus,JC,et al.(1990).Science.249(4971):915-918)。 影响功能:一个代表性批次产品以整合素αvβ3依赖性方式阻止了M21人黑素瘤细胞粘附到纤维蛋白原(Fg)、血管性血友病因子(VWF)或纤连蛋白(FN)包被的表面(Pilch,J.,et al.(2002).J. Biol. Chem. 277(24): 21930-21938)。 影响功能:一个代表性批次产品阻止了转移性人类乳腺癌细胞粘附至胶原蛋白I基质上(Felding-Habermann,B.,et al.(2001).《美国Natl.Acad.Sci. U. S. A. 98(4):1853-1858).

Shear-resistant arrest of circulating tumor cells is required for metastasis from the blood stream. Arrest during blood flow can be supported by tumor cell interaction with attached, activated platelets. This is mediated by tumor cell integrin alpha(v)beta3 and cross-linking plasma

The ligand-binding function of integrin adhesion receptors depends on divalent cations. A mutant alpha IIb beta 3 integrin (platelet gpIIb/IIIa) that lacks ligand recognition shows immunologic evidence of a perturbed interaction with divalent cations. This was found to be caused
The vascular barrier is heavily injured following SARS-CoV-2 infection and contributes enormously to life-threatening complications in COVID-19. This endothelial dysfunction is associated with the phlogistic phenomenon of cytokine storms, thrombotic complications, abnormal coagulation, hypoxemia, and multiple organ failure. The mechanisms

Metastasis is the primary cause of death in human breast cancer. Metastasis to bone, lungs, liver, and brain involves dissemination of breast cancer cells via the bloodstream and requires adhesion within the vasculature. Blood cell adhesion within the vasculature depends

Periostin is a critical extracellular regulator in the pathogenesis of liver disorders such as hepatosteatosis, non-alcoholic steatohepatitis, inflammation, and fibrosis. Periostin is also involved in the progression of hepatocellular carcinoma (HCC). However, the molecular mechanisms of periostin in hepatic stellate
