More than 90% of Rett syndrome (RTT) patients have heterozygous mutations in the X-linked methyl-CpG binding protein 2 (MECP2) gene that encodes the methyl-CpG-binding protein 2, a transcriptional modulator. Because MECP2 is subjected to X chromosome inactivation (XCI), girls with RTT either express the wild-type or mutant allele in each individual cell. To test the consequences of MECP2 mutati...

background: there are many therapeutic methods for allergic conditions. cpg oli-gonucleotides play a critical role in immunity via the augmentation of th1 and suppres-sion of th2 responses. objective: in the present study we aimed to estimate the effec-tiveness of intranasal administration of cpg odn plus chenopodium album allergen in allergic asthma compared with the administration of allergen...

Minimally modified oligonucleotides belong to the second-generation antisense class. They are phosphodiester oligonucleotides with a minimum of phosphorothioate linkages in order to be protected against serum and cellular exonucleases and endonucleases. They activate RNase H, have weak interactions with proteins, and have thus a better antisense efficiency. Two of them have been designed from a...

Genomic homogeneity is investigated for a broad base of DNA sequences in terms of dinucleotide relative abundance distances (abbreviated delta-distances) and of oligonucleotide compositional extremes. It is shown that delta-distances between different genomic sequences in the same species are low, only about 2 or 3 times the distance found in random DNA, and are generally smaller than the betwe...

A negative regulating protein (MDBP-2) from rooster liver nuclear extracts binds preferentially to a methylated promoter region 5'TTCACCTTmCGCTATGAGGGGGATCATACTGG3' of the avian vitellogenin II gene (Nucleic Acids Res. 19, 1029-1034, 1991). Treatment of adult and immature roosters with estradiol results in a 90% decrease in the binding activity of MDBP-2 within three days. This corresponds to t...

Progress with antisense oligonucleotide therapies opens a path for future development

An optical tweezers directed parallel DNA oligonucleotide synthesis methodology is described in which controlled pore glass (CPG) beads act as solid substrates in a two-stream microfluidic reactor. The reactor contains two parallel sets of physical confinement features that retain beads in the reagent stream for synthetic reaction but allow the beads to be optically trapped and transferred betw...

We profiled the expression of genes in benign and untreated human prostate cancer tissues using oligonucleotide microarrays. We report here 50 genes with distinct expression patterns in metastatic and confined tumors (Gleason score 6 and 9; lymph node invasive and noninvasive). Validation of expression profiles of 6 genes by quantitative PCR revealed a strong inverse correlation in the expressi...

Objective(s): In this study, for the first time, MF59 adjuvant was used to develop a cholesteryl ester transfer protein (CETP) vaccine. The efficacy of the vaccine was compared with the efficacy of CETP vaccine formulated with Alum/CpG, the formulation that its immunogenicity has been already demonstrated in rabbit and mice. Materials and Methods: Tetanus toxoid- CETP peptide (TT-CETP) was mixe...

To implement the various movement control of hexapod robot, a motion controller based on double-layered central pattern generator (CPG) is proposed in this paper. The novel CPG network composed rhythm layer and layer. neurons are constructed Kuramoto nonlinear oscillator. parameters including frequency, coupling strength, phase difference matrix for four typical gaits planned. mapping relations...
