Description
We examined the effect of quercetin on the gene expression and function of epididymal adipose tissue (EAT) in Western diet-induced obese mice. Quercetin suppressed the increase in the number of macrophages and the decrease in the ratio of CD4+ to CD8+ T cells in EAT, and the elevation of plasma leptin and TNF levels in mice fed the Western diet. Comprehensive gene expression analysis revealed that quercetin suppressed gene expression associated with the accumulation and activation of immune cells, including macrophages and lymphocytes in EAT. It also improved the expression of the oxidative stress-sensitive transcription factor NFB, NADPH oxidases, and antioxidant enzymes. Quercetin markedly increased gene expression associated with mitochondrial oxidative phosphorylation and mitochondrial DNA Quercetin most likely universally suppresses the accumulation and activation of immune cells, including anti-inflammatory cells, whereas it specifically increased gene expression associated with mitochondrial oxidative phosphorylation. Suppression of oxidative stress and NFB activity likely contributed to the prevention of the accumulation and activation of immune cells and resulting chronic inflammation.

Description
We examined early and late gene expression changes using the IT LPS model of Acute Lung Injury (ALI). In this model, injury peaks at day 4 and is almost completely resolved by day 10 in wild type (WT) C57BL/6 mice. In contrast to the pattern in WT mice, lymphocyte-deficient Rag-1 -/- mice exhibit strikingly delayed resolution despite similar initial injury.

Description
Sustained Akt activation induces cardiac hypertrophy (LVH), which may lead to heart failure. This study tested the hypothesis that Akt activation contributes to mitochondrial dysfunction in pathological LVH. Akt activation induced LVH and progressive repression of mitochondrial fatty acid oxidation (FAO) pathways. Preventing LVH by inhibiting mTOR failed to prevent the decline in mitochondrial function but glucose utilization was maintained. Akt activation represses expression of mitochondrial regulatory, FAO, and oxidative phosphorylation genes in vivo that correlate with the duration of Akt activation in part by reducing FOXO-mediated transcriptional activation of mitochondrial-targeted nuclear genes in concert with reduced signaling via PPAR/PGC-1 and other transcriptional regulators. In cultured myocytes Akt activation disrupted mitochondrial bioenergetics, which could be partially reversed by maintaining nuclear FOXO, but not by increasing PGC-1. Thus, although short-term Akt activation may be cardioprotective during ischemia by reducing mitochondrial metabolism and increasing glycolysis, long-term Akt activation in the adult heart contributes to pathological LVH in part by reducing mitochondrial oxidative capacity.

Description
Objectives: Sex hormone receptors are reported to be present in human dental pulp (HDP) cells. The purpose of this study was to examine the biological significance of estrogen and androgen receptors (ER and AR, respectively) in HDP cells. Design: We isolated HDP cells expressing ER- and AR-mRNAs and investigated the expression status of the receptors and the response to sex hormones in the cells. Results: HDP cells expressing ER- and/or AR-mRNAs had the ability to form alizarin red S-positive nodules in which calcium and phosphorus were deposited in vitro and to differentiate into odontoblasts-like cells and dentin-like tissue in vivo. Individual clones isolated from HDP cells exhibited a different expression pattern of mRNA for ER and AR. Some clones expressed ER- and/or ER-mRNAs and the others coexpressed ER- and AR-mRNAs. Using the Ingenuity software, we found that 17-estradiol (E2) and dihydrotestosterone (DHT) could act directly on HDP cells through ER- or androgen signaling-mediated mechanisms. E2 or DHT stimulated the mRNA expression for genes related to odontogenesis of dentin-containing teeth and odontoblast differentiation, suggesting that ER and AR in HDP cells may be involved in dentinogenesis. Conclusions: Our findings provide new insights into the biological significance of sex hormone receptors in HDP cells.

Description
Cancer cells consume large amounts of glucose because of their specific metabolic pathway. However, cancer cells exist in tumor tissue where glucose is insufficient. To survive, cancer cells likely have the mechanism to elude their glucose addiction. Here we show that functional mitochondria are essential if cancer cells are to avoid glucose addiction.

Description
We performed a global analysis of both miRNAs and mRNAs expression across sixteen human cell lines and extracted negatively correlated pairs of miRNA and mRNA which indicate miRNA-target relationship. The many of known-target of miR-124a showed negative correlation, suggesting our analysis were valid. We further extracted physically relevant miRNA-target gene pairs, applying computational target prediction algorism with inverse correlations of miRNA and mRNA expression. Furthermore, Gene Ontology-based annotation and functional enrichment analysis of the extracted miRNA-target gene pairs indicated putative functions of miRNAs.

Description
Excessive MS is known to result in disappearance of the alveolar hard line, enlargement of thePDL space, and destruction of alveolar bone, leading to occlusal traumatism. The regulatory role of MS is believed to play a critical role in the process of alveolar bone remodeling. However, little is known about the effect of excessive MS on expression of osteoclastogenesis-related genes in human PDL cells.

Description
MicroRNAs are small non-coding RNA species, some of which are playing important roles in cell differentiation. However, the level of participations of microRNAs in epithelial cell differentiation is largely unknown. Here, we found that expression levels of four microRNAs (miR-210, miR-338-3p, miR-33a and miR-451) were significantly increased in differentiated stage of T84 cells, compared with undifferentiated stage. Additionally, we demonstrate that miR-338-3p and miR-451 contribute to the formation of epithelial basolateral polarity by facilitating translocalization of beta1 integrin to the basolateral membrane. However, candidate target mRNAs of miR-338-3p and miR-451 and the mechanism behind observed phenomena is uncertain. Then, we performed comprehensive gene expression analysis to identify candidate target mRNAs and understand their mechanisms.
