R.G. Goodwin, D. Friend, S.F. Ziegler, R. Jerzy, et al., "Cloning of the human and murine interleukin-7 receptors: Demonstration of a soluble form and homology to a new receptor superfamily," Cell, 60:941-51, 1990. Raymond Goodwin (Immunex Corp., Seattle): "Interleukin-7 (IL-7) was cloned based on its ability to induce the proliferation of pre-B cells, and has subsequently been shown to have effects on immature and mature T cells. The cloning of the receptor for IL-7 allows for studies to iden

Daniel W. Nebert (University of Cincinnati Medical Center): "This review is the third in a series of comprehensive, up- to-date compilations of data about members of the large cytochrome P450 gene superfamily. It serves to organize a large--and growing--body of sequencing and mapping data on 154 P450 genes

Michel Philippe (Universite de Rennes, Rennes Cédex, France): "In yeast, two critical points of the cell cycle (Start and G1/S) are regulated by the same protein. This protein, called p34cdc2, is coded by the genes cdc2 in Schizzosaccharomyces pombe and CDC28 in Saccharomyces cerevisiae. By complementation of yeast mutants, proteins from higher eucaryotes homologous to cdc2 have been cloned. Moreover, p34cdc2 has been shown to be one of the main components of the well-known M-phase promotin
