MicroRNAs (miRNAs) are endogenous non-coding small RNAs which play important roles in the regulation of gene expression by cleaving or inhibiting the translation of target gene transcripts. Thereinto, some specific miRNAs show regulatory activities in gonad development via translational control. In order to further understand the role of miRNA-mediated(More)
Glutamate dehydrogenase (GDH) plays a crucial role in amino acid deamination and has been used as an inductor of nutrients metabolism. In this study, we cloned and analyzed the GDH cDNAs in diploids (red crucian carp), triploids and tetraploids and characterized their expression profiles upon dietary treatments. Results showed a high sequence similarity of(More)
Rice stripe disease (RSD), caused by rice stripe virus (RSV), is a serious disease in temperate rice-growing areas. We have created an RNAi construct containing coat protein gene (CP) and disease specific protein gene (SP) sequences from RSV. The RNAi construct was transformed into two susceptible japonica varieties, Suyunuo and Guanglingxiangjing, to(More)
Increasing piRNAs provide RNA-interference pathways to regulate transposons and gene expression in germline cells. We demonstrate that Piwi transcripts are exclusively expressed in adult testes and ovaries in teleosts, with triploids showing the highest Piwi expression in the ovaries. Studies in vivo and in vitro showed that hCG and E2 treatment suppressed(More)
The requirement for caspases (ICE-like proteases) were investigated in mediating apoptosis of WEHI7.2 mouse lymphoma cells in response to two death inducers with different mechanisms of action, the glucocorticoid hormone dexamethasone (DX) and the calcium-ATPase inhibitor thapsigargin (TG). Apoptosis induction by these agents followed different kinetics,(More)
Hybrid Megalobrama amblycephala × Culter alburnus represents a population newly formed by interspecific crossing between two different genera. Here we assessed the expression pattern of mRNA and small RNA in newly formed F1, F2 and their progenitors. Large amounts of nonadditively expressed protein-coding genes showed parental expression level dominance(More)
Polyploidy is much rarer in animals than in plants but it is not known why. The outcome of combining two genomes in vertebrates remains unpredictable, especially because polyploidization seldom shows positive effects and more often results in lethal consequences because viable gametes fail to form during meiosis. Fortunately, the goldfish (maternal) ×(More)
It has been shown that piRNA is the largest class of small non-coding RNA in germline cells of animals which plays key roles in transposons regulation and transcriptional activities. In the present study, piRNAs from two small RNA libraries including ovary and testis of Nile tilapia were identified and characterized. By length and k-mer based small RNA(More)
