BACKGROUND The concentration gradient of Bicoid protein which determines the developmental pathways in early Drosophila embryo is the best characterized morphogen gradient at the molecular level. Because different developmental fates can be elicited by different concentrations of Bicoid, it is important to probe the limits of this specification by analyzing(More)
Laccase (EC is a member of multicopper oxidases that have been found in higher plants, fungus, bacterium, and insects. Two types of laccase genes have been detected in many species of insects: laccase1 and laccase2. It has been identified that laccase2 enzyme may play a key role in sclerotization and pigmentation of insect cuticle. But few(More)
The availability of highly sensitive immunoassays enables the detection of antidrug antibody (ADA) responses of various concentrations and affinities. The analysis of the impact of antibody status on drug pharmacokinetics (PK) is confounded by the presence of low-affinity or low-concentration antibody responses within the dataset. In a phase 2 clinical(More)
Activation-associated secreted protein (ASP) had been found in many helminthes, which was associated with pathogenesis and stage transition. A complementary DNA (cDNA) sequence encoding a putative two-domain ASP was obtained from an Angiostrongylus cantonensis fourth-stage larvae cDNA library, which we designated as AgASP. The cDNA of AgASP contains an open(More)
Wolbachia are maternal endosymbiotic bacterium, which infect a diverse range of arthropods, ranging from 20 to 76 % in nature. They are capable of inducing a wide range of reproductive abnormalities to their hosts, such as cytoplasmic incompatibility (CI), which has been proposed to be used as a tool to modify mosquitoes that are resistant to the(More)
Arabidopsis thaliana 5′-3′ EXORIBONUCLEASE4 (AtXRN4) is involved in the degradation of multiple unstable mRNAs and plays important roles in ethylene response, disease resistance and miRNA-mediated RNA decay. However, XRN4-like genes are completely unknown in tomato—an important model system for studying the biological basis of fleshy fruit development. The(More)
BACKGROUND The goal of this study was to assess the association between endometrial thickness on the chorionic gonadotropin (hCG) day and in vitro fertilization and embryo transfer (IVF-ET) outcome in normal responders after GnRH antagonist administration. METHODS A retrospective cohort study was performed in normal responders with GnRH antagonist(More)
β-N-acetylglucosaminidase (GlcNAcase) is a key enzyme in the chitin decomposition process. In this study, we investigated the gene expression profile of GlcNAcases and the regulation mechanism for one of these genes, BmGlcNAcase1, in the silkworm. We performed sequence analysis of GlcNAcase. Using dual-spike-in qPCR method, we examined the expression of(More)
IE-2 of Bombyx mori nucleopolyhedrovirus (BmNPV) has been shown to play important roles in baculovirus infection, which are involved in gene expression and viral replication. However, the mechanism remains unknown. In this paper, by TargetP software, four genes, i.e.-2, odv-e26, odv-e56 and BmNPV-gp101 (Ac-orf116) of BmNPV and Autographa californica(More)
The open reading frame 7a of the Bombyx mori nucleopolyhedrovirus (BmNPV orf7a, Bm7a) encodes a predicted polypeptide consisting of 53 amino acid residues. While this polypeptide’s homologues were found in certain baculoviruses, its function has not yet been studied. A protein structural assay revealed that the polypeptide expressed from this gene contained(More)
