Adhesive Interactions in Normal and Transformed Cells describes the basic mechanisms of the ability of tissue cells to attach to each other and to the extracellular matrix. These adhesive interactions are pivotal regulators of main cellular functions, such as proliferation, survival and migration. The adhesive interactions are involved in embryonic development, regeneration, and also in inflammation and degeneration processes, which are at the basis of many diseases. Serious alterations in cell adhesion caused by the oncogenic transformation play a key role in cancer invasion and metastasis. This volume provides comprehensive information about structural, mechanistic and signaling aspects of adhesive interactions in both normal and cancer cells in comparison. Integration of such aspects of the adhesive process as structure, relation to cell systems of receptors and cytoskeleton, function, signaling pathways, and the alterations in tumor cells constitutes the strongest point of this work. The results of the long-time author's research are included in the book. The author was one of pioneers, who used scanning electron microscopy (SEM) to study the cell surface morphology of normal cultured cells and the cells underwent the oncogenic transformation, processes of their attachment to and spreading on the surfaces of a solid substratum, and also surprising ability of the cells to respond to various geometric configurations of the substrata surfaces. Adhesive Interactions in Normal and Transformed Cells has both biological and medical aspects and, therefore, it can be interesting not only for cell biologists, developmental biologists and cancer researchers, but also for physicians. It is intended for researchers, postdocs, undergraduate and graduate students.
The increasing awareness on the varied consequences of hypogonadism in distinct organs and systems has supported the notion of estrogens as systemic agents. This observation is congruent with the variety of tissues affected by - trogens when used in hormone therapy formulations on hypogonadic women. Apart from the genital tract and the breast, recognized as traditional targets for estrogens, the skeleton, the vascular tree, or the central nervous system, are good examples of territories that have demonstrated sensitivity to estrogens. This evidence has created great interest, as shown by the great amount of lit- ature that has been produced on the bene?ts and risks associated with the use of estrogens. In parallel to the clinical interest, basic research has improved our kno- edge on the complexities involved in estrogen action at the molecular level. Together with effects mediated through speci?c receptors, a concept that has been the mainstay of the interpretation of estrogen action for years, there is enough evidence to hold the notion of receptor-independent effects. The substantial advances in modern technology applied to research have helped in enlightening the particulars of this versatile action of estrogens. This more detailed knowledge on the sophisticated mechanism of action of estrogens has nourished the emergence of multiple hypotheses speculating with the p- sibility of manipulating estrogen action. The notion that a widely extended regulatory system of cell function, as it is the estrogen receptor machinery, might be modulated at wish has arisen as an attractive, although still elusive postulate.
International Review of Cytology presents current advances and comprehensive reviews in cell biology--both plant and animal. Articles in this volume address topics such as class A macrophage scavenger receptors, microtubule transport in the axon, G-protein-coupled receptors, genes involved in the initiation of DNA replication in yeast, phenotype switching in polymorphic tetrahymena, and mitosis and motor proteins. Authored by some of the foremost scientists in the field, each volume provides up-to-date information and directions for future research.
A royal seductionÂ
Crown prince Kristian DeSaunters has been groomed since birth to take his place as leader of his tropical kingdom?with the proper princess by his side. Never one to lose his control, he's stunned by his attraction to the free-spirited American stylist who arrives at the palace in his father's fiancee's entourage. Soon Kris and Landry Norris are sharing an instant sultry attraction that shows no signs of slowing down.Â
Landry couldn't turn down the opportunity of a lifetime to dress the princess-to-be on a private Caribbean island. Falling for Kris is definitely not part of her plan, but the independent LA beauty soon finds herself yearning for a fairy-tale ending of her own. Until someone sets out to sabotage the upcoming nuptials?and Landry becomes the prime suspect. Will Kris and Landry be able to stop a hidden enemy bent on destroying the DeSaunters reign?and save the possibility of a future together?
