Integrin-mediated cell adhesion to type I collagen fibrils.
In the integrin family, the collagen receptors form a structurally and functionally distinct subgroup. Two members of this subgroup, alpha(1)beta(1) and alpha(2)beta(1) integrins, are known to bind to monomeric form of type I collagen. However, in tissues type I collagen monomers are organized into large fibrils immediately after they are released from cells. Here, we studied collagen fibril re...
متن کاملShort-hairpin RNA-mediated MTA2 silencing inhibits human breast cancer cell line MDA-MB231 proliferation and metastasis.
OBJECTIVE To observe the effects of metastasis-associated tumor gene family 2 (MTA2) depletion on human breast cancer cell proliferation and metastasis. METHODS A short-hairpin RNA targeting MTA2 was chemically synthesized and transfected into a lentivirus to construct Lv-shMTA2 for infection into the MDA-MB231 human breast cancer cell line. At 48 hours after infection cells were harvested an...
متن کاملDisialyl GD2 ganglioside suppresses ICAM-1-mediated invasiveness in human breast cancer MDA-MB231 cells
The disialoganglioside GD3 has been considered to be involved in tumor progression or suppression in various tumor cells. However, the significance of the biological functions of GD3 in breast cancer cells is still controversial. This prompted us to study the possible relationship(s) between GD3 expression and the metastatic potential of a breast cancer MDA-MB231 cells as an estrogen receptor n...
متن کاملCooperativity between cell contractility and adhesion.
In living cells, the cytoskeleton connects to the extracellular environment through focal adhesions, multimolecular structures that can sense applied force. A model is presented that for the first time explains why the focal adhesions tend to high-curvature regions at the cell periphery. It is based on experimental evidence for positive feedback between adhesion formation and assembly of actomy...
متن کاملXanthohumol inhibits cellular proliferation in a breast cancer cell line (MDA-MB231) through an intrinsic mitochondrial-dependent pathway.
AIMS Xanthohumol isolated from hops has been reported to exhibit anticancer effects in diverse human cancers. However, its effect on breast cancer has not yet been clearly defined. The purpose of this study was to investigate the effects of xanthohumol on breast cancer cell proliferation. MATERIALS AND METHODS After treatment with 5 μM, 10 μM, and 20 μM xanthohumol for 48 h, cells from the hu...
