In present study, array comparative genomic hybridization was performed in seven typical , four ‐like variants, six diffuse lymphomas DLBCL derived from . The number aberrations higher compared...
Recent evidence suggests that the observed clinical distinctions between lung tumors in smokers and never (NS) extend beyond specific gene mutations, such as EGFR, EML4-ALK, KRAS, some of which have been translated into targeted therapies. However, molecular alterations identified thus far cannot explain all biological disparities NS smokers. To this end, we performed an unbiased genome-wide, comparative study to identify novel genomic aberrations differ NS. High resolution whole genome DNA...
