Curcumin has antileukemic potential that is mediated by dfifferent pathways. Because we could not confirm that the Arylhydrocarbonreceptor, a ligand activated transcription factor, is involved in curcumins antileukemic effects, we performed microarray experiments to have an overall screening of the pathways affected by curcumin in HL-60 cells.

View SamplesThe arylhydrocarbon receptor is a ligand inducible transcription factor. Known to control xenobiotic metabolizing enzymes, it also affects - depending on the cell type - numerous other genes, either directly or indirectly. With respect to the immune system, persistent activation leads to immunosuppression. We asked how the AhR is involved in Langerhans cells. These antigen presenting cells of the skin are responsible for allergies against chemicals (thus xenobiotic metabolism might be relevant) and a recently detected endogenous ligand, FICZ made by UVB radiation from tryptophane, is particularly abundant in the skin.
Langerhans cell maturation and contact hypersensitivity are impaired in aryl hydrocarbon receptor-null mice.

View SamplesTo gain insight into the pathways accounting for the deleterious effects associated with severe mitochondrial dysfunction, we compared the transcriptomic profile in control L3 larvae with that of strong (arrested) nuo-5 RNAi. We also found that the natural compound lutein was able to rescue some of the defective phenotypes we characterized in nuo-5-depleted animals therefore we compared also the transcriptomic profile of stage-matched (L3) cohorts of C. elegans upon strong nuo-5 RNAi, treated and untreated with lutein, with that of animals fed empty vector control.

View SamplesIn this study we compared the transcriptomic profile in control L3 larvae with that of mild or strong (arrested) nuo-5 RNAi. The two treatment (mild and strong) in fact lead to two very different phenotype. The mild supperssion of nuo-5 induces improved healthspand and has pro longevity effect. The strong suppression of the same gene has, on the contrary, deleterious effects such as arrested development.
