The expression of the retinoic acid receptor beta (RAR beta) mRNA is absent or down-regulated in most human breast cancer cell lines. To investigate the role RAR beta may have in regulating the proliferation of breast cancer cells, we used retroviral vector-mediated gene transduction to introduce the human RAR beta gene into two RAR beta-negative breast(More)
Retinoids mediate the normal growth of a variety of epithelial cells and may play an important role in the chemoprevention of breast cancer. Despite the widespread clinical use of retinoids, specific target genes that are regulated by retinoids are relatively poorly characterized. We reported previously that all-trans-retinoic acid (ATRA) mediates(More)
Human lactoferrin (LF) has been reported to inhibit in vitro granulopoiesis by means of decreasing colony-stimulating activity production by monocytes. We performed a series of experiments to determine if the reported experimental results could be replicated using highly purified murine LF and murine target cells. Three different types of experiments were(More)
Overexpression of cyclin D1 protein is observed in the majority of breast cancers, suggesting that dysregulated expression of cyclin D1 might be a critical event in breast cancer carcinogenesis. We investigated whether retroviral-mediated expression of cyclin D1 might affect all-trans-retinoic acid (ATRA)-mediated growth inhibition and differentiation of(More)
Aberrant p53 expression is frequently observed in mammary epithelial cells obtained from women at high risk for developing breast cancer and is a predictor for the subsequent development of malignancy. Tamoxifen has recently been shown to reduce the incidence of noninvasive breast cancer in high-risk women, but the molecular mechanism of tamoxifen(More)
The computing for development community knows how to build user interfaces using qualitative methods for text illiterate users, especially on mobile devices. However, little work has been done specifically targeting Deaf users in developing regions who cannot access voice or text. This paper describes a multi-disciplinary collaboration towards iterative(More)
Management of Meloidogyne incognita on soybean as affected by winter small grain crops or fallow, two tillage systems, and nematicides was studied. Numbers of M. incognita did not differ in plots planted to wheat and rye. Yields of soybean planted after these crops also did not differ. Numbers of M. incognita were greater in fallow than in rye plots, but(More)
Application of 1,2-dibromo-3-chloropropane (DBCP) and subsoiling under the row in Tifton sandy loam heavily infested with Meloidogyne incognita increased yields of four soybean cultivars. These cultivars have levels of resistance to M. incognita as follows: 'Hutton', high; 'Essex', intermediate; and 'Davis' and 'Ransom', low. After growing these four(More)
Yields of 'McNair 800' soybeans, Glycine max (L.) Merr., were significantly increased with ethylene dibromide + chloropicrin, DBCP, phenamiphos, and aldicarb applied at-planting and with phenamiphos, aldicarb, and DBCP applied postplant to soil infested with Meloidogyne incognita (Kofoid and White) Chitwood. Yields of 'GaSoy 17' were significantly increased(More)
A liquid culture system employing slide chambers was developed to facilitate the study of proliferation and differentiation of mouse neutrophilic granulocytes and cells of the monocyte-macrophage series. Cultures were initiated with 1-2.5 X 10(4) light density marrow cells which had been fractionated on Ficoll-Hypaque. In the presence of colony-stimulating(More)
