E2 multimeric scaffold for vaccine formulation: immune response by intranasal delivery and transcriptome profile of E2-pulsed dendritic cells

Background The E2 multimeric scaffold represents a powerful delivery system able to elicit robust humoral and cellular immune responses upon systemic administrations. Here recombinant E2 scaffold displaying the third variable loop of HIV-1 Envelope gp120 glycoprotein was administered via mucosa, and the mucosal and systemic immune responses were analysed. To gain further insights ...

AnaLysis of Expression on human chromosome 21, ALE-HSA21: a pilot integrated web resource

Transcriptome studies have shown the pervasive nature of transcription, demonstrating almost all the genes undergo alternative splicing. Accurately annotating all transcripts of a gene is crucial. It is needed to understand the impact of mutations on phenotypes, to shed light on genetic and epigenetic regulation of mRNAs and more generally to widen our knowledge about cell ...

DDX11L: a novel transcript family emerging from human subtelomeric regions

Background The subtelomeric regions of human chromosomes exhibit an extraordinary plasticity. To date, due to the high GC content and to the presence of telomeric repeats, the subtelomeric sequences are underrepresented in the genomic libraries and consequently their sequences are incomplete in the finished human genome sequence, and still much remains to be learned about ...

Investigation of Gamma-aminobutyric acid (GABA) A receptors genes and migraine susceptibility

Background Migraine is a neurological disorder characterized by recurrent attacks of severe headache, affecting around 12% of Caucasian populations. It is well known that migraine has a strong genetic component, although the number and type of genes involved is still unclear. Prior linkage studies have reported mapping of a migraine gene to chromosome Xq 24–28, a region containing ...

Massive-Scale RNA-Seq Analysis of Non Ribosomal Transcriptome in Human Trisomy 21

Hybridization- and tag-based technologies have been successfully used in Down syndrome to identify genes involved in various aspects of the pathogenesis. However, these technologies suffer from several limits and drawbacks and, to date, information about rare, even though relevant, RNA species such as long and small non-coding RNAs, is completely missing. Indeed, none of published ...

A Novel Pseudoautosomal Human Gene Encodes A Putative Protein Similar to Ac-like Transposases

We report the cloning of a novel gene, called Tramp, in the Xp/Yp PAR region that has a functional homologue on the Y chromosome and escapes X-inactivation. This gene encodes, within a single exon, a putative protein that has amino acid similarity with transposases of the Ac family. Flanking this gene we have identified putative terminal inverted repeats (TIRs) and a duplicate ...

Multiple pathogenic and benign genomic rearrangements occur at a 35 kb duplication involving the NEMO and LAGE2 genes

The X-linked dominant and male-lethal disorder incontinentia pigmenti (IP) is caused by mutations in a gene called NEMO (IKK-γ). We recently reported the structure of NEMO and demonstrated that most IP patients carry an identical deletion that arises due to misalignment between repeats. Affected male abortuses with the IP deletion had provided clues that a second, incomplete copy ...

A Novel Pseudoautosomal Gene Encoding a Putative GTP-Binding Protein Resides in the Vicinity of the Xp/Yp Telomere

We report the cloning of a novel Xp/Yp pseudoautosomal gene called PGPL, and demonstrate that PGPL, like other pseudoautosomal genes, escapes X inactivation and has a functional homologue on the Y chromosome. This gene is expressed in all the tissues examined and is highly conserved across several species. The PGPL gene encodes a protein of 442 amino acids and shows the consensus ...

Long-Range Sequence Analysis in Xq28: Thirteen Known and Six Candidate Genes in 219.4 kb of High GC DNA Between the RCP/GCP and G6PD Loci

DNA comprising 219 447 bp was sequenced in nine cosmids and verified at >99.9% precision. Of the standard repetitive elements, 187 Alus make up 20.6% of the sequence, but there were only 27 MERs (2.9%) and 17 L1 fragments (1.6%). This may be characteristic of such high GC (57%) regions. The sequence also includes an 11.3 kb tract duplicated with 99.2% identity at a distance of 38 ...

Differential Expression Pattern of XqPAR-Linked Genes SYBL1 and IL9R Correlates with the Structure and Evolution of the Region

The recently discovered second pseudoautosomal region (XqPAR) contains at least two genes, IL9R and SYBL1. Recent findings show that, like XpPAR genes, IL9R escapes X inactivation and its Y allele is also expressed, but SYBL1 seems to act like an X-linked gene, expressed from the active X chromosome but not from the inactive X or Y. Here we show that differences are also seen in ...

Differentially regulated and evolved genes in the fully sequenced Xq/Yq pseudoautosomal region

Human sex chromosomes, which are morphologically and genetically different, share few regions of homology. Among them, only pseudoautosomal regions (PARs) pair and recombine during meiosis. To better address the complex biology of these regions, we sequenced the telomeric 400 kb of the long arm of the human X chromosome, including 330 kb of the human Xq/YqPAR and the telomere. ...
