Estrogens are thought to promote labor by increasing the expression of pro-contraction genes in myometrial cells. The specific estrogen receptors ((ERs: ERα and ERβ (also known as ESR1 and ESR2)) and G protein-coupled receptor 30 (GPR30; also known as G protein-coupled estrogen receptor 1)) and signaling pathways that mediate these actions are not clearly(More)
Members of the Ras superfamily of small GTP-binding proteins, gamma-subunits of heterotrimeric G proteins and nuclear lamin B are subject to a series of post-translational modifications that produce prenylcysteine methylester groups at their carboxyl termini. The thioether-linked polyisoprenoid substituent can be either farnesyl (C15) or geranylgeranyl(More)
An asporogenous strain of Bacillus subtilis, IS53, transformed with plasmid pPA102, produces the protective antigen (PA) component of the tripartite toxin of B. anthracis. Addition of yeast extract was required to support growth and PA production in all the media examined. Protective antigen expression was down-regulated during exponential growth and(More)
