how to identify a gene on human chromsome 11

[Soonmyoung Paik, M.D.]

You may be interested in reading the article by Jeff Trent's group 
published in Nature Genetics December 1996 issue. They used cDNA 
microarray to identify the genes whose expression have changed when 
chromosome 6 was inserted into tumorigenic cells which resulted in 
suppression of tumorigenic phenotype.
