Rajnish A. Gupta,Nilay Shah,Kevin C. Wang,Jeewon Kim,Hugo M. Horlings,David J. Wong,Miao-Chih Tsai,Tiffany Hung,Pedram Argani,John L. Rinn,Yulei Wang,Pius Brzoska,Benjamin Kong,Rui-Chun Li,Robert B. West,Marc J. van de Vijver,Saraswati Sukumar,Howard Y. Chang +17 more
TL;DR: It is shown that lincRNAs in the HOX loci become systematically dysregulated during breast cancer progression, indicating that l incRNAs have active roles in modulating the cancer epigenome and may be important targets for cancer diagnosis and therapy.

TL;DR: In this paper, gene expression and genetic profiles of cells purified from cancerous and normal breast tissue using markers previously associated with stem-cell-like properties were determined using markers from the TGF-β pathway, where its inhibition induced a more epithelial phenotype.

TL;DR: In this article, an ultra-high-density array that tiles the promoters of 56 cell-cycle genes was used to interrogate 108 samples representing diverse perturbations, identifying 216 transcribed regions that encode putative lncRNAs, many with RT-PCR-validated periodic expression during the cell cycle.

Direct mutagenesis of Ha- ras -1 oncogenes by N -nitroso- N -methylurea during initiation of mammary carcinogenesis in rats
TL;DR: Each of the Ha-ras-1 oncogenes present in tumours induced by N-nitroso-N-methylurea, but not in those induced by 7,12-dimethylbenz(a)anthracene, became activated by the same G → A transition, the type of mutation induced by W → N → G → M transition.
