High-throughput RNA sequencing has revealed more pervasive transcription of the human genome than previously anticipated. However, the extent of natural antisense transcripts' (NATs) expression, their regulation of cognate sense genes, and the role of NATs in cancer remain poorly understood. Here, we use strand-specific paired-end RNA sequencing (ssRNA-seq) data from 376 cancer samples covering...

The Arabidopsis genome contains a large number of gene pairs that encode sense and antisense transcripts with overlapping 3' regions, indicative for a potential role of natural antisense transcription in regulating sense gene expression or transcript processing. When we mapped poly(A) transcripts of three plant gene pairs with long overlapping antisense transcripts, we identified an unusual tra...

A surprise that has emerged from transcriptomics is the prevalence of genomic antisense transcription, which occurs counter to gene orientation. While frequent, the roles of antisense transcription in regulation are poorly understood. We built a synthetic system in Escherichia coli to study how antisense transcription can change the expression of a gene and tune the response characteristics of ...

Antisense transcription is a pervasive phenomenon, but its source and functional significance is largely unknown. We took an expression-based approach to explore microRNA (miRNA)-related antisense transcription by computational analyses of published whole-genome tiling microarray transcriptome and deep sequencing small RNA (smRNA) data. Statistical support for greater abundance of antisense tra...

OBJECTIVE Coagulation factor XI is proposed as therapeutic target for anticoagulation. However, it is still unclear whether the antithrombotic properties of factor XI inhibitors influence atherosclerotic disease and atherothrombosis. Our aim is to investigate whether factor XI antisense oligonucleotides could prevent thrombus formation on acutely ruptured atherosclerotic plaques. APPROACH AND...

The mu opioid receptor mediates ingestive behavior: mu-selective agonists stimulate food intake and antagonists reduce intake in many ingestive situations. Antisense oligodeoxynucleotides directed against each of the four exons of the MOR-1 clone were equally effective in reducing spontaneous food intake and body weight in rats. However, antisense probes directed against only exon 1 or 4 of the...

Retroviral vectors were engineered to express either sense (MoTiN-TRPsie+) or sense and antisense (MoTN-TRPsie+/-) RNAs containing the human immunodeficiency virus type-1 (HIV-1) trans -activation response (TAR) element and the extended packaging (Psie) signal. The Psie signal includes the dimer linkage structure (DLS) and the Rev response element (RRE). Amphotropic vector particles were used t...

The putative primase gene and other genes associated with the Sfi21-prototype genome replication module are highly conserved in Streptococcus thermophilus bacteriophages. Expression of antisense RNAs complementary to the putative primase gene (pri3.1) from S. thermophilus phage kappa 3 provided significant protection from kappa 3 and two other Sfi21-type phages. Expression of pri3.10-AS, an ant...

Antisense technologies consist of the utilization oligonucleotides or oligonucleotide analogs to interfere with undesirable biological processes, commonly through inhibition expression selected genes. This field holds a lot promise for treatment very diverse group diseases including viral and bacterial infections, genetic disorders, cancer. To date, drugs approved in clinics clinical trials tar...

The expression of an antisense RNA revealed that an Mn-catalase was required in Thermus thermophilus for aerobic but not for anaerobic growth. The antisense system is based on the constitutive expression of a "bicistronic" transcript consisting of the kanamycin resistance gene mRNA followed by the antisense RNA against the selected target.
