Description
Dorsomorphin is a small molecule inhibitor of type I bone morphogenic protein receptors (BMPRs). We have found that dorsomorphin affects a wide range of T cell function. In order to obtain the bigger picture of the effects of DM in T cell activation. transcriptomic analysis was performed using mouse primary CD25-CD4+ T cells with either DM (4 M) or vehicle in the presence or absence of stimulation by anti-CD3 and -CD28 antibodies.

Description
Invasion into deep myometrium and/or lymphovascular space is a well-known risk factor for endometrial cancer metastasis, resulting in poor prognosis. It is therefore clinically important to identify novel molecules that suppress tumor invasion. Reduced expression of the metastasis suppressor, KISS1 (kisspeptin), and its endogenous receptor, GPR54, has been reported in several cancers, but the significance of the KISS1/GPR54 axis in endometrial cancer metastasis has not been clarified. Metastin-10 is the minimal bioactive sequence of genetic products of KISS1. Clinicopathological analysis of 92 endometrial cancers revealed overall survival is improved in cancers with high expression of GPR54. Through RNAi and mousemodel analyses, metastin-10 was predicted to suppress invasion and metastasis of GPR54-expressing endometrial cancers. These data suggest that metastin-10 may induce genetic changes in the metastatic character of endometrial cancers.

Description
Using killer cell lectin-like receptor G1 as a marker to distinguish terminal effector cells from memory precursors, we found that despite their diverse cell fates both subsets possessed remarkably similar gene expression profiles and functioned as equally potent killer cells. However, only the memory precursors were capable of making IL-2 thus defining a novel effector cell that was cytotoxic, expressed granzyme B, and produced inflammatory cytokines in addition to IL-2. This effector population then differentiated into long-lived protective memory T cells capable of self-renewal and rapid re-call responses. Mechanistic studies showed that cells that continued to receive antigenic stimulation during the later stages of infection were more likely to become terminal effectors. Importantly, curtailing antigenic stimulation towards the tail-end of the acute infection enhanced the generation of memory cells. These studies support the decreasing potential model of memory differentiation and show that the duration of antigenic stimulation is a critical regulator of memory formation

Description
Ascorbic acid (AA) is a powerful antioxidant and play as a cofactor for various enzymes in vivo. In this study, we investigated the effect of AA depletion on gene expression in the liver and lipid metabolism by using SMP30/GNL knockout (KO) mice which are unable to biosynthesis AA. First, we performed microarray analysis. Briefly, SMP30/GNL KO mice were weaned and divided into two groups; AA-depleted and supplemented groups, which mice were free access to water containing 1.5 g/L AA. After 4 weeks, mRNA was isolated and purified from the liver. In this study, Affymetrix GeneChip was used for microarray analysis. Actually, AA-depletion altered many gene expressions related to lipid metabolism. Especially, Cytochrome P450 7a1 (Cyp7a1), a late-limiting enzyme of bile acid biosynthesis, gene expression was significantly up-regulated. We also confirmed Cyp7a1 protein levels by Western blotting. Next, we investigated the influence of AA depletion on lipid metabolism. We examined the lipid and bile acid levels in the liver, plasma, and gallbladder from SMP30/GNL KO mice. Amount of total bile acid (TBA), free fatty acid (FA), total cholesterol (TC), triglyceride (TG), and phospholipids (PL) were measured by colorimetric method. AA depletion reduced TBA levels in the liver and gallbladder. However, FA, TC, TG, and PL in the plasma and liver were not changed by AA depletion. Although Cyp7a1 gene expression and protein levels were increased by AA depletion, amount of bile acid were reduced. Conclusively, we have shown that AA depletion reduced bile acid biosynthesis and elevated Cyp7a1 gene expression and protein levels. Thus, AA is an essential for bile acid biosynthesis pathway.

Description
Epithelial ovarian cancer is the leading cause of death among gynecologic malignancies. Diagnosis usually occurs after metastatic spread, largely reflecting vague symptoms of early disease combined with lack of an effective screening strategy. Epigenetic mechanisms of gene regulation, including DNA methylation, are fundamental to normal cellular function and also play a major role in carcinogenesis. To elucidate the biological and clinical relevance of DNA methylation in ovarian cancer, we conducted expression microarray analysis of 39 cell lines and 17 primary culture specimens grown in the presence or absence of DNA methyltransferase (DNMT) inhibitors. Two parameters, induction of expression and standard deviation among untreated samples, identified 378 candidate methylated genes, many relevant to TGF-beta signaling. We analyzed 43 of these genes and they all exhibited methylation. Treatment with DNMT inhibitors increased TGF-beta pathway activity. Hierarchical clustering of ovarian cancers using the 378 genes reproducibly generated a distinct gene cluster strongly correlated with TGF-beta pathway activity that discriminates patients based on age. These data suggest that accumulation of age-related epigenetic modifications leads to suppression of TGF-beta signaling and contributes to ovarian carcinogenesis.
