Abstract The lack of efficacious treatments for clear cell renal carcinoma (ccRCC) has led to a poor 5-year survival rate. Here, we found that the expression ADAM metallopeptidase with thrombospondin type 1 motif 9 (ADAMTS9) antisense RNA (ADAMTS9-AS1) is commonly decreased in ccRCC tissues. Decreased ADAMTS9-AS1 associated advanced stages and prognosis patients. Additionally, promoter hypermet...

BACKGROUND Autism spectrum disorders (ASD) manifest with neurodevelopmental phenotypes including communicative, social and behavioral impairments that affect as many as 1 in 88 children. The majority of autism cases have no known genetic cause, suggesting complex genetics of the disorder, but a few genes of large effect have been identified. METHODS In order to identify novel ASD genetic corr...

Antisense RNA was a rather uncommon term in a physiology environment until short interfering RNAs emerged as the tool of choice to knock down the expression of specific genes. As a consequence, the concept of RNA having regulatory potential became widely accepted. Yet, there is more to come. Computational studies suggest that between 15 and 25% of mammalian genes overlap, giving rise to pairs o...

Antisense molecules are emerging as a powerful tool to correct splicing defects. Recently, we identified a homozygous deep-intronic mutation (F5 c.1296+268A>G) activating a cryptic donor splice site in a patient with severe coagulation factor V (FV) deficiency and life-threatening bleeding episodes. Here, we assessed the ability of 2 mutation-specific antisense molecules (a morpholino oligonucl...

BACKGROUND Although genome-wide transcriptional analysis has been used for many years to study bacterial gene expression, many aspects of the bacterial transcriptome remain undefined. One example is antisense transcription, which has been observed in a number of bacteria, though the function of antisense transcripts, and their distribution across the bacterial genome, is still unclear. METHOD...

Antisense-based molecules targeting HIV-1 RNA have the potential to be used as part of gene or drug therapy to treat HIV-1 infection. In this study, HIV-1 RNA was screened to identify more conserved and accessible target sites for ribozymes based on the hepatitis delta virus motif. Using a quantitative screen for effects on HIV-1 production, we identified a ribozyme targeting a highly conserved...

Gene therapy may be of benefit in human immunodeficiency virus type 1 (HIV-1)-infected individuals by virtue of its ability to inhibit virus replication and prevent viral gene expression. It is not known whether anti-HIV-1 gene therapy strategies based on antisense or transdominant HIV-1 mutant proteins can inhibit the replication and expression of clinical HIV-1 isolates in primary CD4+ T lymp...

Retroviruses display a strong selective pressure to maintain the dimeric nature of their genomic RNAs, suggesting that dimerization is essential for viral replication. Recently, we identified the cis-element required for initiation of human immunodeficiency virus type I (HIV-I) RNA dimerization in vitro. The dimerization initiation site (DIS) is a hairpin structure containing a self-complementa...

Specific gene silencing has been demonstrated in a number of organisms by the introduction of antisense RNA. Mutagenesis of host-encoded factors has begun to unravel the mechanism of several forms of RNA-mediated gene silencing and has suggested that it may have been conserved through evolution. This has led to the identification of certain host genes, which, when mutated, abrogate this phenome...
