in this paper we investigate a new notion of bases in hilbert spaces and similarto fusion frame theory we introduce fusion bases theory in hilbert spaces. we also introducea new denition of fusion dual sequence associated with a fusion basis and show that theoperators of a fusion dual sequence are continuous projections. next we dene the fusionbiorthogonal sequence, bessel fusion basis, hilbe...

As previously established in yeast, two sequences within mRNAs are responsible for their specific localization to the mitochondrial surface-the region coding for the mitochondrial targeting sequence and the 3'UTR. This phenomenon is conserved in human cells. Therefore, we decided to use mRNA localization as a tool to address to mitochondria, a protein that is not normally imported. For this pur...

Most lipomas are characterized by translocations involving the HMGA2 gene in 12q14.3. These rearrangements lead to the fusion of HMGA2 with an ectopic sequence from the translocation chromosome partner. Only five fusion partners of HMGA2 have been identified in lipomas so far. The identification of novel fusion partners of HMGA2 is important not only for diagnosis in soft tissue tumors but also...

All retroviruses and retrotransposons studied to date regulate the relative levels of gag and pol/int gene products post-transcriptionally from a single mRNA. In these genetic elements the production of protein encoded by the pol and int genes is attenuated by a translational stop or frameshift in the reading frame preceding their coding regions in the mRNA. We show here that the Drosophila ret...

In vitro display technologies such as mRNA and cDNA display are powerful tools to create and select functional peptides. However, in some cases, efficiency of mRNA-protein fusion is very low, which results in decreased library size and lower chance of successful selection. In this study, to improve mRNA-protein fusion efficiency, we prepared an mRNA display library of a protein with random N- a...

The functionally undefined Stac3 gene, predicted to encode a SH3 domain- and C1 domain-containing protein, was recently found to be specifically expressed in skeletal muscle and essential to normal skeletal muscle development and contraction. In this study we determined the potential role of Stac3 in myoblast proliferation and differentiation, two important steps of muscle development. Neither ...

Antisense technology has great potential for the control of RNA expression, but there remain few successful applications of the technology. Expressed antisense RNA can effectively down-regulate expression of a gene over long periods, but cannot differentiate partly identical sequences, such as the mRNA of fusion genes or those with point mutants. We have designed a structured form of expressed ...

BACKGROUND Pandemic strains of HIV-1 (group M) encode a total of nine structural (gag, pol, env), regulatory (rev, tat) and accessory (vif, vpr, vpu, nef) genes. However, some subtype A and C viruses exhibit an unusual gene arrangement in which the first exon of rev (rev1) and the vpu gene are placed in the same open reading frame. Although this rev1-vpu gene fusion is present in a considerable...
