Differential display is an easily applied method for comparing gene expression in a variety of systems. We used a nonradioactive differential display technique to analyze X-ray-induced lymphomas derived from Eμ-pim-1 transgenic and nontransgenic mice. Fragments of 11 differentially regulated genes were identified, three of which are novel sequences. One of the cloned fragments contained sequences of a mouse VL30 retro-element that was significantly overexpressed in a subset of lymphomas as compared with non- lymphomatous tissue. Interestingly, these lymphomas also displayed high levels of c-myc transcripts. An altered expression pattern of a glutathione S-transferase homologue was identified in several lymphomas. Moreover, a cytotoxic T-lymphocyte lipase appeared to be overexpressed specifically in lymphoma-containing spleen tissue, and the results suggest that it may be related to the endogenous immune response against lymphoma development.
