Identification of microRNA clusters cooperatively acting on epithelial to mesenchymal transition in triple negative breast cancer.

abstract：:Antigenic variation of the pilus is an essential component of Neisseria gonorrhoeae pathogenesis. Unidirectional recombination of silent pilin DNA into an expressed pilin gene allows for substantial sequence variation of this highly immunogenic surface structure. While the RecA protein is required for pilin gene recom...

abstract：:Gene promoters are enriched in guanine clusters that potentially fold into quadruplex structures. Such quadruplexes were implicated in the regulation of gene expression, plausibly by interacting with transcription factors. We showed previously that homodimers of the myogenic transcription factor MyoD bound in vitro mo...
