PURPOSE: Prolactin regulatory element-binding protein (PREB), a member of the WD-repeat protein family, has been recognized as a transcriptional factor that regulates prolactin promoter activity in the anterior pituitary of rats. PREB is expressed not only in the pituitary but also in various other tissues, including the adipose tissue. Previous studies have shown that PREB acts as a transcriptional regulator and suppresses the expression of the adiponectin gene in cultured 3T3L1 preadipocytes...

Increased blood plasma concentration of the sulphur amino acid homocysteine (Hcy) is considered as an independent risk factor of the neurodegenerative diseases. However, the detailed molecular mechanisms by which Hcy leads to neurotoxicity have yet to be clarified. Recent research has suggested that neurotoxicity of Hcy may involve negative regulation of neural stem cell (NSC) proliferation. In the current study, primary NSCs were isolated from neonatal rat brain hippocampus and the inhibition in cell growth was observed after exposure to l50 μM and 500 μM L-Hcy...

Diagnosis of invasive pulmonary aspergillosis (IPA) is challenging. The objective of the study was to assess the value of microbiological tests to the diagnosis of IPA in the absence of non-specific radiological data. A retrospective study of 23 patients with suspicion of IPA and positivity of some microbiological diagnostic tests was performed. These tests included conventional microbiological culture, detection of Aspergillus galactomannan (GM) antigen and in some patients (1 → 3)-β-D-glucan (BDG) and Aspergillus fumigatus DNA using the LightCycler(®) SeptiFast test...

American Indian (AI) children are disproportionately affected by unintentional injuries, with injury mortality rates approximately 2.3 times higher than the combined rates for all children in the United States. Although multiple risk factors are known to contribute to these increased rates, a comprehensive, culturally informed curriculum that emphasizes child safety is lacking for this population. In response to this need, academic and tribal researchers, tribal community members, tribal wellness staff, and national child safety experts collaborated to develop a novel child safety curriculum...

The sequential or co-inoculation of grape must with non-Saccharomyces yeast species and Saccharomyces cerevisiae wine yeast strains has recently become a common practice in winemaking. The procedure intends to enhance unique aroma and flavor profiles of wine. The extent of the impact of non-Saccharomyces strains depends on their ability to produce biomass and to remain metabolically active for a sufficiently long period. However, mixed-culture wine fermentations tend to become rapidly dominated by S. cerevisiae, reducing or eliminating the non-Saccharomyces yeast contribution...

Inflammatory signaling pathways induced by Helicobacter pylori remain unclear, having been studied mostly on cell-line models derived from gastric adenocarcinoma with potentially altered signaling pathways and nonfunctional receptors. Here, H. pylori-induced signaling pathways were investigated in primary human gastric epithelial cells. Inflammatory response was analyzed on chemokine mRNA expression and production after infection of gastric epithelial cells by H. pylori strains, B128 and B128ΔcagM, a cag type IV secretion system defective strain...

Alpha-fetoprotein (AFP) is an early serum growth factor in fetal embryonic development and hepatic oncogenesis. A growing number of investigations of AFP as a tumor-specific biomarker have concluded that AFP is an important target for cancer treatment. AFP also plays an immunomodulatory role in the treatment of several autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, myasthenia gravis, and thyroiditis. In an effort to support biochemical screening and drug design and discovery, we attempted to express and purify human AFP in a Bac-to-Bac system...

The transcription factor STAT1 displays antitumor functions for certain forms of cancer via immunoregulatory and cell-autonomous pathways. Paradoxically, STAT1 can promote the survival of different tumor types treated with chemotherapeutic drugs through mechanisms that are not clearly defined. Herein, we demonstrate that STAT1 displays prosurvival effects in human KRAS colon tumor cells by regulating pathways that converge on the initiation of mRNA translation. Specifically, STAT1 increases PI3K class IB signaling and promotes the downregulation of the programmed cell death protein 4 (PDCD4), a protein with tumor-suppressive properties...

Amar Bahadur Singh, Jingwen Liu
Peroxisome proliferator-activated receptor δ (PPARδ) regulates many genes involved in lipid metabolism. Hepatic lysophosphatidylcholine acyltransferase 3 (LPCAT3) has critical functions in triglycerides transport and ER stress response due to its unique ability to catalyze the incorporation of polyunsaturated fatty acids into phospholipids. Previous studies identified liver X receptor as the transcription factor controlling LPCAT3 expression in mouse liver tissue. Here we show that the hepatic LPCAT3 gene is transcriptionally regulated by PPARδ...

Living cells receive biochemical and physical information from the surrounding microenvironment and respond to this information. Multiscale hierarchical substrates with micro- and nanogrooves have been shown to mimic the native extracellular matrix (ECM) better than conventional nanopatterned substrates; therefore, substrates with hierarchical topographical cues are considered suitable for investigating the role of physical factors in tissue functions. In this study, precisely controllable, multiscale hierarchical substrates that could mimic the micro- and nanotopography of complex ECMs were fabricated and used to culture various cell types, including fibroblasts, endothelial cells, osteoblasts, and human mesenchymal stem cells...

Proteasome-dependent turnover of mitochondrial outer membrane (OMM)-associated proteins is one of the mechanisms for maintaining proper mitochondrial quality and function. However, the underlying pathways and their implications in human disease are poorly understood. Huntington's disease (HD) is a fatal, inherited neurodegenerative disorder caused by expanded CAG repeats in the N terminal of the huntingtin gene (mutant Huntingtin, mtHtt). In this study, we show an extensive degradation of the OMM protein MCL1 (Myeloid cell leukemia sequence 1) in both HD mouse striatal cells and HD patient fibroblasts...

Adipose-derived stem cells (ASCs) are abundantly present in the mammary microenvironment and can promote breast cancer malignancy by differentiating into myofibroblasts. However, it remains largely unclear which role tumor-derived extracellular vesicles (TEVs) play in this process. Here, we used microfabricated, type I collagen-based 3-D tissue culture platforms to investigate the effect of breast cancer cell-derived TEVs on ASCs myofibroblast differentiation and consequential changes in extracellular matrix remodeling and vascular sprouting...

We examine associations between childhood sexual abuse (CSA) and substance abuse, the role of mental health indicators as mediators in these associations and whether or not associations differ by gender. Data are from 14,063 respondents aged 18-76 years from the 2004-2005 Canadian Gender, Alcohol, and Culture: An International Study (GENACIS). Multiple logistic regression models were used to examine associations between CSA and substance abuse variables, controlling for socio-demographic factors. Odds were adjusted by indicators of mental health to assess if these variables mediated associations between CSA and substance abuse...

Connective tissue disease related pulmonary arterial hypertension (CTD-PAH) is characterized by vascular remodeling, endothelial dysfunction and inflammation. Endocan is a novel endothelial dysfunction marker. The aim of the present study was to investigate the role of endocan in CTD-PAH. Monocrotaline (MCT)-induced PAH rats were used as the CTD-PAH model. Short hairpin RNA packed in a lentiviral vector used to inhibit endocan expression was intratracheally instilled in rats prior to the MCT injection. Endocan was found to be increased in the serum and lung of MCT-induced PAH rats...

The Müllerian duct develops into the oviduct, uterus, and vagina, all of which are quite distinct in their morphology and function. The epithelial fate of these female reproductive organs in developing mice is determined by factors secreted from the stroma; however, how stromal differentiation occurs in the female reproductive organs derived from the Müllerian duct is still unclear. In the present study, roles of retinoic acid (RA) signaling in developing female reproductive tracts were investigated. Retinol dehydrogenase 10 (RDH10) and aldehyde dehydrogenase family 1 subfamily A2 (ALDH1A2) mRNAs and proteins and transactivation activity of endogenous RA were found in the stroma of proximal Müllerian ducts and gradually decreased from the proximal to caudal regions in fetal mice...
