In a mouse model of elastase-induced emphysema, the effect of tetomilast against the emphysema development observed in C57BL/6J (C57) could be also detected in phosphodiesterase (PDE) 4D(+/+) but not in PDE4B(+/+), PDE4B(-/-), and PDE4D(-/-) mice. Based on this result, we hypothesized that the difference in the efficacy of tetomilast among these strains of mice might result from the differences in the levels of the target molecules of tetomilast other than PDE4 in each mouse strain. To test this hypothesis, we used microarrays to compare the expression levels of genes in the lungs of each mouse strain. The expression profiling by array demonstrated that the levels of cyclin-dependent kinase inhibitor 1 (CDKN1a) in PDE4B(+/+), PDE4B(-/-), and PDE4D(-/-) were higher than those in C57 and PDE4D(+/+).

View SamplesLactic acid bacteria confer a variety of health benefits. Here we investigate the mechanisms by which Lactobacillus brevis KB290 enhances cell-mediated cytotoxic activity. We fed a diet containing KB290 (3 10^9 colony-forming units/g) , or potato starch, to 9-week-old female BALB/c mice for 1, 4, 7, or 14 days and examined the cytotoxic activity of splenocytes was measured. RNA was extracted from the spleen and analyzed for gene expression by DNA microarray.

View SamplesA total of 40 female mice 129/SV aged 3-6 months and weighting 18-25 g were used (Janvier, Le Genest-St-Isle, France). NTS was injected in mice (10 l/gBW/day) during three consecutive days. The total number of mice was divided to five treatment groups as followed: 8 mice were injected with PBS and fed with vehicle, 8 mice were injected with NTS and fed with vehicle, 8 mice were injected with NTS and fed with low dose DDR1i, 8 mice were injected with NTS and fed with high dose DDR1i and 8 mice were injected with NTS and fed with Imatinib. All treatments were provided by oral gavage. Treatment was started one day [PM{1}] prior first injection of NTS or PBS. The average food intake was controlled by weighing the food every three days. Mice were found to consume about 4g/day/mouse [PM{2}] which was similar to all groups.

View SamplesExpression data from mice exposed to intermittent hypoxia and mice reared for 12 months. We used microarrays to analyze the transcriptome of hippocampus from mice exposed to intermittent hypoxia or aged mice.
Treatment of intermittent hypoxia increases phosphorylated tau in the hippocampus via biological processes common to aging.

View SamplesThis array set was used to identify the genes that are highly expressed in the mouse suprachiasmatic nucleus (SCN). Because pharmacological inhibition of Gai/o activity with pertussis toxin hampers intercellular synchronization and causes dampened rhythms of the entire SCN, we hypothesized that member(s) of the Regulator of G protein Signaling (RGS) family might contribute to synchronized cellular oscillations in the SCN. To test this hypothesis, we surveyed all known mouse Rgs genes for their expression by using GeneChip and selected the genes that are highly expressed in the SCN for further analysis.
Circadian regulation of intracellular G-protein signalling mediates intercellular synchrony and rhythmicity in the suprachiasmatic nucleus.

View SamplesBisphenol A (BPA), an endocrine-disrupting chemical (EDC), is a well-known, ubiquitous estrogenic chemical. To investigate the effects of fetal exposure to low-dose BPA on the development of the prostate, we first examined the alterations of in situ sex steroid hormonal environment in the mouse urogenital sinus (UGS).
