The PlA2 polymorphism of integrin β3 enhances outside-in signaling and adhesive functions

Bray, Paul F.; Vijayan, K. Vinod; Roos, Christine; Goldschmidt-Clermont, Pascal J.

Genetic factors are believed to influence the development of arterial thromboses. Because integrin αIIbβ3 plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney embryonal 293 cells overexpressing the PlA1 or PlA2 polymorphic ...

Growth as a solid tumor or reduced glucose concentrations in culture reversibly induce CD44-mediated hyaluronan recognition by Chinese hamster ovary cells.

Kincade, P W; Zheng, Z; Pummill, P E; Cummings, R D

The density, molecular isoform, and posttranslational modifications of CD44 can markedly influence growth and metastatic behavior of tumors. Many CD44 functions, including some involving tumors, have been attributed to its ability to recognize hyaluronan (HA). However, only certain CD44-bearing cell...

The Chinese hamster cell lines E36 and CHOK1 dramatically differ in susceptibility to amphotropic murine leukemia virus (A-MuLV) and gibbon ape leukemia virus (GALV); E36 cells are highly susceptible to both viruses, CHOK1 cells are not. We have previously shown that GALV can infect E36 cells by usi...
