ABSTRACT; The effects of DHEA were compared with those of DHT using gene expression array profiles in human LNCaP prostate cancer cells. LNCaP cells were exposed to DHEA (300 nM), DHT (300 nM), or vehicle for 48 hrs, and mRNA was isolated. mRNA expression was measured using Affymetrix HU-95 gene chi...

Multi-walled carbon nanotubes (MWCNT) cause lung fibrosis in rodents and exacerbate airway fibrosis in the mouse ovalbumin model of allergic asthma. Interleukin 13 (IL-13) is a key cytokine secreted by T helper type 2 (Th2) cells. IL-13 is up-regulated in human asthma and animal models that activat...

Exposure to vanadium pentoxide (V2O5) is a cause of occupational bronchitis. We evaluated gene expression profiles in cultured human lung fibroblasts exposed to V2O5 in vitro in order to identify candidate genes that could play a role in airway remodeling associated with V2O5-induced bronchitis. Gen...

Surface topography impacts on cell growth and differentiation, but it is not trivial to generate homogeneous surface structures and to define the specific morphological parameters of relevance. In this study, we have compared gene expression profiles of mesenchymal stem cells (MSCs) on nanostructure...

Entomopathogenic nematodes (EPNs) of the genera Heterorhabditis are obligate and lethal insect parasites. In recent years they have been used increasingly as biological control agents. These EPNs are symbiotically associated with bacteria of the genera Photorhabdus. The bacterial symbionts are essen...

Although intestinal microbiota play a pivotal role in the development of host immune system this biological issue was not so far studied in great detail. In this study we examined immune response of Caco-2 enterocytes after incubation with common probiotic Bifidobacterium animalis subsp. lactis BB-1...
