BACKGROUND Internal ribosomal entry sites (IRESs) provide alternative, cap-independent translation initiation sites in eukaryotic cells. IRES elements are important factors in viral genomes and are also useful tools for bi-cistronic expression vectors. Most existing RNA structure prediction programs are unable to deal with IRES elements. RESULTS We(More)
The internal ribosomal entry site (IRES) functions as cap-independent translation initiation sites in eukaryotic cells. IRES elements have been applied as useful tools for bi-cistronic expression vectors. Current RNA structure prediction programs are unable to predict precisely the potential IRES element. We have designed a viral IRES prediction system(More)
The baculovirus/insect cell-expression system has proven to be a valuable tool for rapid expression of abundant recombinant proteins for research purposes and has been increasingly exploited for the production of vaccine candidates for commercial use. Furthermore, baculovirus has been discovered to be capable of efficiently transducing a wide variety of(More)
Alzheimer's disease (AD) is the most common form of dementia. Severe memory loss, confusion, and impaired cognitive abilities characterize AD. It was only a century after Alzheimer's discovery that scientists were able to shed light on the mystery of its cause, but AD has also become a globally important health issue and the treatment of AD is a challenge(More)
A bi-cistronic baculovirus transfer vector was constructed based on the 5'UTR internal ribosome entry site (IRES) of the Rhopalosiphum padi virus (RhPV). Recombinant baculoviruses containing the red fluorescent protein gene and green fluorescent protein gene flanking the RhPV 5'UTR IRES can simultaneously produce dual fluorescence in recombinant(More)
Traditional Chinese medicines have been widely investigated for the treatment of Alzheimer's disease (AD) because none of the current therapies-either the cholinesterase inhibitors or antagonist of N-methyl-d-aspartate receptors-has profound effects on halting the progression of AD. In recent years, scientists have isolated many active compounds from herbs,(More)
Recombinant baculoviruses are suitable for the high-level production of large multi-protein complexes. A tri-cistronic expression vector was constructed by the inclusion of two internal ribosome entry sites (IRESs). In this novel polycistronic vector, one single polyhedrin promoter controlled the transcription of a tri-cistronic transcript. Also, the first(More)
UNLABELLED Enterovirus 71 (EV71), a member of Picornaviridae, is associated with severe central nervous system complications. In this study, we identified a cellular microRNA (miRNA), miR-197, whose expression was downregulated by viral infection in a time-dependent manner. In miR-197 mimic-transfected cells, EV71 replication was inhibited, whereas the(More)
The interaction between the synaptic adhesion molecules neuroligins and neurexins is essential for connecting the pre- and post-synaptic neurons, modulating neuronal signal transmission, and facilitating neuronal axogenesis. Here, we describe the simultaneous expression of the extracellular domain of rat neuroligin-1 (NL1) proteins along with the enhanced(More)
The advantages of using traceable fluorescent protein (enhanced green fluorescent protein; EGFP) and a secretory alkaline phosphatase (SEAP) have been used to generate a reporter gene: the secretory fluorescent protein (SEFP). Sf21 cells, infected with the recombinant baculovirus containing the SEFP gene, revealed both traceable fluorescence and easily(More)
