Colon cancer; Expression; NPRL2; Real-time PCR; Tumor suppressor gene

Genetic and epigenetic factors affecting DNA methylation and gene expression are known to be involved in the development of colon cancer, but the full range of genetic alterations and many key genes involved in the pathogenesis of colon cancer remain to be identified. NPRL2 is a candidate tumor suppressor gene identified in the human chromosome 3p21.3 region. We evaluated the role of this ... more

Colon cancer; EpCAM; Wnt/β-catenin

The aims of this study were to explore the correlation between the expression of EpCAM and the Wnt/β-catenin pathway in human colon cancer and its clinical significance for the evaluation of cancer prognosis. Samples from colon cancer, para-carcinoma, or benign intestinal tissue from individual patients (50) and from normal intestinal mucosal tissues (20) were obtained from the Pathology ... more

Chromosome instability; Colon cancer; Hec1; Metastasis; Nuclear division cycle 80; Proliferation

Chromosome instability is a common feature of tumor cells, and may be an important mechanism in tumor formation. Nuclear division cycle 80 (NDC80) is closely associated with the stability of chromosomes. Therefore, we investigated the relationship between NDC80 and development of colon cancer using a range of methods. Western blotting and immunohistochemistry were employed to determine ... more

Gene expression; Hypoxia; Muscle; Pig

Hypoxia influences many physiological processes, such as respiration, cardiovascular, neurophysiology, and digestion. Skeletal muscle is an important motor organ, which relies on oxygen of oxidation; however, the study of hypoxia in skeletal muscle is lacking. In order to understand the effect of hypoxia on skeletal muscle, we determined the expression level of four hypoxia-related genes ( ... more

Gene expression; Hyperplasia and hypertrophy; Megalobrama amblycephala; Morphological analysis; Muscle fiber

Skeletal muscle growth is regulated by both positive and negative factors, such as myogenic regulatory factors (MRFs) and myostatin (MSTN), and involves both hyperplasia and hypertrophy. In the present study, morphological changes during muscle development in Megalobrama amblycephala were characterized and gene expression levels were measured by quantitative real-time polymerase chain ... more

Annual Medicago; Gene expression; Microarray analysis; Salinity

The present study was conducted to evaluate the responses of three annual Medicago species (M. truncatula, M. laciniata, and M. polymorpha) to salinity. We analyzed publicly available microarray data in NCBI pertaining to salinity-response genes in M. truncatula. Our data search identified Tubby C2 (TLP) and ethylene responsive ... more

Amino acid transporter; Branched-chain amino acid; Gene expression; Pigs

Excess Leu reduces the availability of Ile and Val in pigs likely by reducing absorption of the latter amino acids (AA). Twenty-four crossbred pigs were used to evaluate the effect of excess Leu alone or with surplus Ile and Val on the expression of cationic (b0,+AT and CAT1) and neutral (B0AT1) AA transporters in the small intestine, liver, and skeletal ... more

Carotenoid; Citrus; Gene expression; Stability

Red-fleshed oranges (Citrus sinensis) contain high levels of carotenoids and lycopene. The growing consumer demand for products with health benefits has increased interest in these types of Citrus cultivars as a potential source of nutraceuticals. However, little is known about the physiology of these cultivars under Brazilian conditions. Transcriptome and gene ... more

Bovine mammary epithelial cells; Deep sequencing; Escherichia coli; Gene expression; Klebsiella pneumoniae; Staphylococcus aureus

The goal of this study was to characterize the transcriptome of primary bovine mammalian epithelial cells (pBMECs) and to identify candidate genes for response and resistance to Staphylococcus aureus (strain S108), Escherichia coli (strain E23), and Klebsiella pneumoniae (strain K96) infection. Using Solexa sequencing, approximately 4.9 million total sequence tags ... more

Barley; Drought stress; Gene cloning; Gene expression; HbSINA4; Hordeum vulgare

Hulless barley is an important crop cereal in Tibetan, China. Drought is a major abiotic stress in barley production. In this study, we cloned the drought-related HbSINA4 gene from the variety ‘Himalaya 10’ and analyzed its expression patterns under different drought and rehydration conditions. The cDNA of HbSINA4 was 1052 bp long, including an open reading frame of 771 ... more
