The hormonal stimulation of mammary gland morphogenesis is believed to occur through growth factor receptor signaling pathways. To determine the importance of the epidermal growth factor receptor (EGFR) pathway, we examined extracts of inguinal mammary glands from prepubertal and pubertal mice for tyrosine-phosphorylated EGFR and other erbB receptors.(More)
BACKGROUND Data on integrase inhibitor resistance come primarily from clinical trials and in vitro studies. We examined results of all clinically indicated integrase genotypic resistance tests (GRTs) performed at a US national referral lab from 2009 through 2012. METHODS Integrase sequences and demographic data were compiled with paired protease-reverse(More)
The discovery of multiple EGF-like ligands and erbB receptors offers the potential for a highly diverse signaling system allowing specific ligand/receptor complexes to be created in response to a certain hormone(s) or stage of mammary development. The known erbB receptors and several of the erbB-related ligands are synthesized by the normal mammary gland(More)

BACKGROUND Transmitted drug resistance (TDR) limits antiretroviral options and thus complicates the management of HIV-positive patients. HIV disproportionately affects the southern US, but available national estimates of TDR prevalence principally reflect large metropolitan centres outside this region. METHODS The Duke/UNC Acute HIV Program has collected(More)
The signaling pathways associated with estrogen-induced proliferation of epithelial cells in the reproductive tract have not been defined. To identify receptor tyrosine kinases that are activated in vivo by 17 beta-estradiol (E2), uteri from ovariectomized mice were examined for enhanced tyrosine phosphorylation of various receptors and a receptor substrate(More)
Transgenic mice harboring the ovine FSHbeta (oFSHbeta) promoter plus first intron (from -4741 to +759 bp) linked to a luciferase reporter gene (oFSHbetaLuc) were generated to determine whether this promoter can direct tissue-specific expression in vivo and serve as a model for studying hormonal regulation of the FSHbeta gene. Of six lines of transgenic mice(More)
