Adrenomedullin; Leukocyte; RNA; RT-PCR

Blood samples are used as a biological source to discover biomarkers of hematological and non-hematological disorders. The present study shows the impact of different experimental conditions associated with cell lysis buffer, TRI-reagent protocol and blood cell storage buffer and their correlation with the quantity, quality and Adrenomedullin gene expression levels of total ... more

Germin; In situ hybridization; RT-PCR; Salt stress; Wheat development

The response of plants to biotic and abiotic stress factors involves biochemical, physiological, morphological, and developmental changes. Salt stress has been the subject of extensive studies due to the low salt tolerance of many crop plants. Germin and germin-like gene products are known to be involved in various aspects of plant development, such as defense, embryonic development and ... more

Cytokinin; Duplication; Maize (Zea mays); Phylogenetic analysis; RT-PCR; Two-component signal system

Cytokinins play many vital roles in plant development and physiology. In plants, cytokinin signals are sensed and transduced by the two-component signal system. This signaling cascade is typically composed of three proteins: a sensory histidine kinase, a histidine phosphotransfer protein, and a response regulator. Through a comprehensive genome-wide analysis of the maize (Zea mays ... more

Cell wall; Polygalacturonase; RT-PCR; Sweet pepper; Transmission electron microscopy; Ultrastructure

Activity and expression of polygalacturonase (PG), a hydrolytic enzyme involved in ultrastructural changes in the pericarp of sweet pepper (Capsicum annaum), were investigated at different ripening stages of the pepper cultivars Mandi and Talanduo. Molecular cloning of CaPG was carried out by constructing a cDNA library from three stages of fruit ripening. Morphological ... more

Clone; Differential expression; Invariant chain; Muscovy duck; RACE; RT-PCR

The invariant chain (Ii) plays an important role as a chaperone for MHC II maturation and facilitates antigen presentation in vertebrates. We cloned, characterized and made a homology analysis of healthy adult muscovy duck Ii (MDIi), from a poultry farm in the suburban district of Hefei city in China, by rapid amplification of cDNA ends (RACE)-PCR and by measuring expression of the ... more

Apoptosis; CDV; Fas receptor; RT-PCR; Vero cells

We evaluated the expression of the Fas receptor gene in Vero cells infected with the Lederle vaccine strain of canine distemper virus using RT-PCR. Vero cells were plated, and after being grown for 24 h in MEM with 5% FBS, 80-90% confluent monolayer cultures were infected with the virus. The cells were harvested at 3, 6, 9, and 15 h post-infection. Uninfected Vero cells were used as a ... more

Follicular development; Growth factors; RT-PCR

The components of the insulin-like growth factor (IGF) system appear to be involved in regulation of ovarian follicular growth and atresia in the pig. We investigated the expression pattern of mRNAs for IGF1 (IGF1), its binding proteins (IGFBP1, IGFBP2, IGFBP3, and IGFBP5), and epidermal growth factor in swine follicle cells and ovarian tissue ... more

IHHNV; Litopenaeus vannamei; Molecular diagnosis; RT-PCR; Shrimp aquaculture; Shrimp virus

The Pacific whiteleg shrimp Litopenaeus vannamei (Penaeidae) is one of the most important cultivated species in world aquaculture. In Brazil, the northeastern states are home to the main shrimp producers. As shrimp aquaculture has expanded and intensified, diseases have progressively become one of the most serious threats to this industry. Infectious hypodermal and hematopoietic ... more

Cytokinin; Response regulator; Rice; RT-PCR

Response regulators are part of a two-component regulatory system. The type-A Arabidopsis response regulators act as negative regulators. To understand the function of type-A response regulators in the model monocot plant, rice (Japonica cultivar-group: Zhonghua11), we overexpressed two type-A OsRR genes, OsRR3 and OsRR5 (pACT1:OsRR3 and pACT1:OsRR5). We hoped to gain insight ... more
