  1. Integrin‐mediated calcium signaling and regulation of cell adhesion by intracellular calcium.Michael D. Sjaastad & W. James Nelson - 1997 - Bioessays 19 (1):47-55.
    Integrins are ubiquitous trans‐membrane adhesion molecules that mediate the interaction of cells with the extracellular matrix (ECM). Integrins link cells to the ECM by interacting with the cell cytoskeleton. In cases such as leukocyte binding, integrins mediate cell‐cell interactions and cell‐ECM interactions. Recent research indicates that integrins also function as signal transduction receptors, triggering a number of intracellular signaling pathways that regulate cell behavior and development. A number of integrins are known to stimulate changes in intracellular calcium levels, resulting in (...)

  • Molecular biology and anatomy of Drosophila olfactory associative learning.Gregg Roman & Ronald L. Davis - 2001 - Bioessays 23 (7):571-581.
    Most of our current knowledge of olfactory associative learning in Drosophila comes from the behavioral and molecular analysis of mutants that fail to learn. The identities of the genes affected in these mutants implicate new signaling pathways as mediators of associative learning. The expression patterns of these genes provide insight into the neuroanatomical areas that underlie learning. In recent years, there have been great strides in understanding the molecular and neuroanatomical basis for olfaction in insects. It is now clear that (...)

  • Why do so many stimuli induce tyrosine phosphorylation of FAK?José Luis Rodríguez-Fernández - 1999 - Bioessays 21 (12):1069-1075.
    Engagement of integrins and other adhesion receptors can induce tyrosine phosphorylation of focal adhesion kinase (FAK), a tyrosine kinase present in focal adhesions. Furthermore, in addition to adhesion receptors, a surprising variety of stimuli, acting either on specific surface receptors or on intracellular molecules, such as PKC or Rho, can induce also tyrosine phosphorylation of FAK. I suggest that a potential mechanism by which such distinct factors may modulate the tyrosine phosphorylation of FAK is the promotion of integrin or other (...)

  • The mammalian acrosome reaction: Gateway to sperm fusion with the oocyte?Catherine A. Allen & David P. L. Green - 1997 - Bioessays 19 (3):241-247.
    Mammalian sperm undergo discharge of a single, anterior secretory granule following their attachment to the zona pellucida surrounding the oocyte. This secretory discharge is known for historical reasons as the acrosome reaction. It fulfils a number of purposes and without it, sperm are unable to penetrate the zona pellucida and fuse with the oocyte. In this review, we focus on the role of the acrosome reaction in the development of fusion competence in sperm. Any naturally occurring membrane fusion has two (...)
