Growth cones are actively influenced by substrate-bound adhesion molecules.

As axons advance to appropriate target tissues during development, their growth cones encounter a variety of cell adhesion molecules (CAMs) and extracellular matrix molecules (ECM molecules). Purified CAMs and ECM molecules influence neurite outgrowth in vitro and are thought to have a similar function in vivo. For example, when retinal ganglion cell (RGC) neurons are grown on different CAM and...

Distribution and possible interactions of actin-associated proteins and cell adhesion molecules of nerve growth cones.

Actin filaments and their interactions with cell surface molecules have key roles in tissue cell behaviour. Axonal pathfinding during embryogenesis, an especially complex cell behaviour, is based on the migration of nerve growth cones. We have used fluorescence immunocytochemistry to examine the distribution in growth cones, their filopodia and lamellipodia of several actin-associated proteins ...

Multiple substrate binding by cytochrome P450 3A4: estimation of the number of bound substrate molecules.

Cytochrome P450 3A4, a major drug-metabolizing enzyme in man, is well known to show non-Michaelis-Menten steady-state kinetics for a number of substrates, indicating that more than one substrate can bind to the enzyme simultaneously, but it has proved difficult to obtain reliable estimates of exactly how many substrate molecules can bind. We have used a simple method involving studies of the ef...

Cadherins are a superfamily of adhesion molecules

Cadherins are a family of membrane receptors that mediate calcium dependent homophilic cell–cell adhesion. Cadherins play a key role in the regulation of organ and tissue development during embryogenesis. In adult organisms, these proteins are responsible for formation of stable cell–cell junctions and maintenance of normal tissue structure. Disruption in expression or function of cadherins may...

Cell adhesion molecules regulate Ca2+-mediated steering of growth cones via cyclic AMP and ryanodine receptor type 3

Axonal growth cones migrate along the correct paths during development, not only directed by guidance cues but also contacted by local environment via cell adhesion molecules (CAMs). Asymmetric Ca2+ elevations in the growth cone cytosol induce both attractive and repulsive turning in response to the guidance cues (Zheng, J.Q. 2000. Nature. 403:89-93; Henley, J.R., K.H. Huang, D. Wang, and M.M. ...
