Many genes are regulated as an innate part of the eukaryotic cell cycle, and a complex transcriptional network helps enable the cyclic behavior of dividing cells. This transcriptional network has been studied in Saccharomyces cerevisiae (budding yeast) and elsewhere. To provide more perspective on these regulatory mechanisms, we have used microarrays to(More)
Although it is increasingly evident that cancer is influenced by signals emanating from tumor stroma, little is known regarding how changes in stromal gene expression affect epithelial tumor progression. We used laser capture microdissection to compare gene expression profiles of tumor stroma from 53 primary breast tumors and derived signatures strongly(More)
OBJECTIVE To determine the prevalence of carpal tunnel syndrome (CTS) in Latino poultry-processing workers. METHODS Symptoms and nerve conduction studies were used to prospectively assess 287 Latino poultry-processing workers and 226 Latinos in other manual-labor occupations. RESULTS The prevalence of CTS was higher in poultry-processing (8.7%) compared(More)
Leukotriene B4 (LTB4) and prostaglandin E2 (PGE2) are shown to be potent immunoregulatory lipid mediators. Here, we examined the effects of LTB4 and PGE2 on the differentiation of immunosuppressive CD4+CD25+Foxp3+ T regulatory cells (Treg) and pro-inflammatory IL-17-producing cells (Th17) from murine naïve CD4+ T cells. Using MACS-purified murine CD4+CD62L+(More)
Studies investigating the association between endothelial nitric oxide synthase (eNOS) gene polymorphisms and preeclampsia reported contradictory or nonconclusive results. We performed a meta-analysis of 18 genetic association studies that examined the relationship between preeclampsia and the G894T, 4a/b and T-786C polymorphisms of the eNOS gene. Subgroup(More)
CONTEXT In trials, thiazolidinediones (TZDs) increase fracture risk in women, but the effects of discontinuation are unknown. OBJECTIVE The objective was to investigate the effects of TZD use and discontinuation on fractures in women and men. DESIGN This was a longitudinal observational cohort study using data from the Action to Control Cardiovascular(More)
Endothelial progenitor cells (EPCs) are essential in vasculogenesis and wound healing, but their circulating and wound level numbers are decreased in diabetes. This study aimed to determine mechanisms responsible for the diabetic defect in circulating and wound EPCs. Since mobilization of BM EPCs occurs via eNOS activation, we hypothesized that eNOS(More)
Adult bone marrow-derived mesenchymal stem cells (MSCs) are able to differentiate into myofibroblasts and be recruited into wound lesions and contribute to wound healing. The cellular and molecular mechanisms responsible for MSC trafficking and differentiation, however, are poorly understood. Local resting resident fibroblasts are activated after injury and(More)
OBJECTIVE Neovascularization, angiogenesis, and collagen constriction are essential for wound healing. We tested whether vascular endothelial growth factor-C (VEGF-C) can promote collagen constriction, capillary sprouting (angiogenesis), and invasion/migration of bone marrow-derived endothelial progenitor cells into collagen (vasculogenesis). METHODS We(More)
Following the first human infection with the influenza A (H10N8) virus in Nanchang, China in December 2013, we identified two additional patients on January 19 and February 9, 2014. The epidemiologic, clinical, and virological data from the patients and the environmental specimen collected from 23 local live poultry markets (LPMs) were analyzed. The three(More)
