Mammalian genomes harbor a larger than expected number of complex loci, in which multiple genes are coupled by shared transcribed regions in antisense orientation and/or by bidirectional core promoters. To determine the incidence, functional significance, and evolutionary context of mammalian complex loci, we identified and characterized 5,248 cis-antisense(More)
AntiHunter is a new web-based tool for the identification of expressed sequence tag (EST) antisense transcripts from BLAST output. In order to perform an analysis, user is required to input a genomic sequence plus an associated list of transcript names and coordinates of the genomic region (i.e. genome annotation). After masking the repeated regions (if(More)
An increasing number of eukaryotic and prokaryotic genes are being found to have natural antisense transcripts (NATs). There is also growing evidence to suggest that antisense transcription could play a key role in many human diseases. Consequently, there have been several recent attempts to set up computational procedures aimed at identifying novel NATs.(More)
(ROS) are present in low amounts and their action can be effectively counteracted by the antioxidant system of the cells. However, cancer cells have higher ROS levels as a consequence of their increased metabolic activity, leading to a state of chronic oxidative stress. Increased levels of ROS are indeed involved in tumorigenesis and progression, conferring(More)
We recently identified the long non-coding RNA (ncRNA) TRPM2-AS as a key regulator of survival in prostate cancer [1]. This essential role, coupled to the TRPM2-AS low-expression levels in healthy tissues, makes this ncRNA a suitable therapeutic target for further clinical studies. To get insights into the survival mechanism controlled by this molecule, we(More)
Discovering cooperative Transcription Factors (TF's) within the genome is a computationally challenging problem, tackled through Monte Carlo-like analysis by the Co-Bind code, developed at the Department of Genetics of the St. Louis Washington University. Due to its statistical nature, Co-Bind is characterized by very long execution times, order of days on(More)
UNLABELLED TargetFinder is a new software tool to search a database of annotated sequences for transcription factor binding sites located in context with other important transcription regulatory signals and regions, like the TATA element, the promoter, and so on, thereby greatly reducing the background usually associated with this kind of search.
