Abstract
Cholesterol increases the risk of colorectal cancer. Liver X receptor (LXR), retinoid X receptor (RXR)α and sterol regulatory element binding protein (SREBP)-1c are transcriptional regulators of lipid metabolism. Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) serves an essential role in angiogenesis and development, but its role in cancer is controversial. The expression of COUP-TFII, LXR, RXRα and SREBP-1c in colorectal cancer, as well as their association with clinicopathologic features, was assessed, and their utility as prognostic indicators in colorectal cancer evaluated. Colorectal cancer samples (n=707 patients) were analyzed for COUP-TII, LXR, RXRα and SREBP-1c expression by immunohistochemistry. Overall survival curves of patients with tumors expressing different levels of these proteins were produced and risk factors were assessed. Of the 707 patients, 32.7, 50.9, 56.4, and 41.7% were positive for COUP-TFII, LXR, RXRα, and SREBP-1c, respectively. The lack of COUP-TFII or LXR expression was associated with lower overall survival rates (P=0.0154 for COUP-TFII, and 0.0113 for LXR). Following adjustment for other clinical risk factors (age, sex, tumor size, grade, vascular invasion, and Tumor-Node-Metastasis stage), the lack of COUP-TFII or LXR expression was a negative independent prognostic factor for survival. The expression of COUP-TFII and LXR alone or in combination may be biomarkers to indicate a positive prognosis in patients with colorectal cancer.

Abstract
INTRODUCTION Club cell protein 16 (CC16) is the most abundant protein in bronchoalveolar lavage fluid. CC16 has anti-inflammatory properties in smoke-exposed lungs, and chronic obstructive pulmonary disease (COPD) is associated with CC16 deficiency. Herein, we explored whether CC16 is a therapeutic target for COPD. AREAS COVERED We reviewed the literature on the factors that regulate airway CC16 expression, its biologic functions and its protective activities in smoke-exposed lungs using PUBMED searches. We generated hypotheses on the mechanisms by which CC16 limits COPD development, and discuss its potential as a new therapeutic approach for COPD. EXPERT OPINION CC16 plasma and lung levels are reduced in smokers without airflow obstruction and COPD patients. In COPD patients, airway CC16 expression is inversely correlated with severity of airflow obstruction. CC16 deficiency increases smoke-induced lung pathologies in mice by its effects on epithelial cells, leukocytes, and fibroblasts. Experimental augmentation of CC16 levels using recombinant CC16 in cell culture systems, plasmid and adenoviral-mediated over-expression of CC16 in epithelial cells or smoke-exposed murine airways reduces inflammation and cellular injury. Additional studies are necessary to assess the efficacy of therapies aimed at restoring airway CC16 levels as a new disease-modifying therapy for COPD patients.

Abstract
BACKGROUND COUP transcription factors are required for the regulation of gene expression underlying development, differentiation, and homeostasis. They have an evolutionarily conserved function, being a known marker for neurogenesis from cnidarians to vertebrates. A homologue of this gene was shown previously to be a neuronal and nematocyte differentiation marker in Hydra. However, COUP-TFs had not previously been studied in a colonial cnidarian. METHODOLOGY/PRINCIPAL FINDINGS We cloned a COUP-TF homologue from the colonial marine cnidarian Hydractinia echinata. Expression of the gene was analysed during normal development, allorecognition events and ectopic Wnt activation, using in situ hybridisation and quantitative PCR. During normal Hydractinia development, the gene was first expressed in post-gastrula stages. It was undetectable in larvae, and its mRNA was present again in putative differentiating neurons and nematocytes in post-metamorphic stages. Global activation of canonical Wnt signalling in adult animals resulted in the upregulation of COUP-TF. We also monitored a strong COUP-TF upregulation in stolons undergoing allogeneic interactions. COUP-TF mRNA was most concentrated in the tissues that contacted allogeneic, non-self tissues, and decreased in a gradient away from the contact area. Interestingly, the gene was transiently upregulated during initial contact of self stolons, but dissipated rapidly following self recognition, while in non-self contacts high expression levels were maintained. CONCLUSIONS/SIGNIFICANCE We conclude that COUP-TF is likely involved in neuronal/nematocyte differentiation in a variety of contexts. This has now been shown to include allorecognition, where COUP-TF is thought to have been co-opted to mediate allorejection by recruiting stinging cells that are the effectors of cytotoxic rejection of allogeneic tissue. Our findings that Wnt activation upregulates COUP-TF expression suggests that Wnts' role in neuronal differentiation could be mediated through COUP-TF.

Abstract
BACKGROUND Clara cell 10-kDa protein (CC10) is a multifunction protein with anti-inflammatory and immunomodulatory effects; hence we compared the CC10 expression between chronic rhinosinusitis (CRS) patients with and without nasal polyps (NPs), analyzed its association with disease severity and response to surgery, and explored its regulation via cytokines. METHODS The plasma and tissue CC10 levels were compared between controls and CRS patients with and without NPs by means of quantitative RT-PCR, ELISA, and immunohistochemistry. Computed tomography (CT) scan and endoscopy findings and symptoms were scored. Nasal explant culture was used to explore the effect of TNF-alpha, IL-1beta, IL-4, INF-gamma, and IL-10 on CC10 gene regulation. RESULTS Compared with controls, the CC10 expression in sinonasal mucosa was significantly inhibited in both CRS patients with and without NPs. There was a significant further decrease of CC10 expression in patients with NPs and asthma. No difference in CC10 plasma levels was found between controls and patients. CC10 levels inversely correlated with preoperative CT scores, and postoperative endoscopy and symptom scores. TNF-alpha, IL-1beta and IL-4 inhibited, whereas INF-gamma and IL-10 promoted CC10 production in nasal mucosa. A significantly faster decay of CC10 transcripts was seen after IL-1beta treatment. IL-1beta and IL-10 induced thyroid transcription factor-1 expression. INF-gamma increased, whereas IL-4 inhibited hepatocyte nuclear factor-3alpha expression. CONCLUSION CC10 may take part in the pathogenesis of CRS and correlates with disease severity and response to surgery. Different cytokines can regulate CC10 expression in nasal mucosa differentially through modulating mRNA stability and certain transcriptional factors expression.

Abstract
Analysis of the transcriptional regulation of the Clara cell secretory protein (CCSP) gene has resulted in the characterization of several trans-acting factors that regulate the activity of this gene. However, little is known about negative regulatory elements involved in CCSP gene transcription. Using transient transfections of luciferase reporter constructs driven by various fragments of the Neotomodon CCSP (nCCSP) promoter, we identified an inhibitory region that contains an inverted CCAAT box located -225 to -221 bp upstream of the transcriptional start site. Sequence analysis in a broad region of the nCCSP promoter (-744/+33) identified another potentially important CCAAT motif (-459/-455). Gel shift and supershift assays indicated that the transcription factor NF-Y binds to both CCAAT boxes. Mutation of the CCAAT motif prevented the in vitro binding of NF-Y and led to a significant increase of CCSP promoter activity in both pulmonary (H441) and non-pulmonary (HeLa and MCF-7) cells, suggesting that NF-Y is involved in a negative transcriptional regulation that may potentially contribute to the highly cell-specific expression of the anti-inflammatory CCSP gene.

Abstract
The chicken ovalbumin upstream promoter transcription factor II, COUP-TFII, is a member of the orphan nuclear receptor transcription factor family. Genetic ablation of COUP-TFII results in early embryonic lethality and demonstrates that this gene is required for cardiac and vascular development. Expression of COUP-TFII persists throughout postnatal life in various tissues including the female reproductive tract. However, the physiological function of COUP-TFII in female reproduction has not been extensively analyzed. Here, we provide phenotypic evidences that haploinsufficiency of COUP-TFII in mice demonstrates an important role of COUP-TFII for normal female reproduction. COUP-TFII +/- females show significantly reduced fecundity, irregular estrus cycles, delayed puberty, and retarded postnatal growth. Analysis of the reduced fertility revealed that although ovarian function was normal with respect to ovulation, the ovaries have reduced ability to synthesize progesterone in response to exogenous gonadotropins. This reduction is due to the reduction of the expression of steroidogenic enzymes important for progesterone synthesis and the reduction of vascularization in COUP-TFII heterozygotes. Analysis of uterine function demonstrated a reduced response to an experimentally induced decidual cell reaction indicating that the ability of the uterus to support embryo implantation was reduced. Taken together, our data show global impact of gene dosage effects of COUP-TFII on female postnatal life and indicates requirement of COUP-TFII in normal female reproduction, in particular for uterine endometrial functions during the peri-implantation period.

Abstract
Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII) plays an essential role in angiogenesis and development. It is differentially expressed in tumor cell lines, but its role in carcinogenesis is largely unknown. We demonstrate here that noninvasive human lung cancer cells become invasive when COUP-TFII was expressed. The expression of extracellular matrix degrading proteinases, such as matrix metalloproteinase 2 and urokinase-type plasminogen activator, was up-regulated in these cells. This finding was confirmed by transduction of different human lung cancer cell lines with COUP-TFII protein and also by using antisense expression. We observed disorganization of actin filaments and focal adhesion kinase phosphorylation in COUP-TFII-transfected human lung cancer cells in addition to the increase in extracellular metalloproteinase activity. These results suggest that COUP-TFII may be considered as a new target for anticancer therapies.
