SNRPB and cancer: The candidate metastasis suppressor genes in the differential region of deletion of chromosome 2 that we identified, based on prior evidence of metastasis suppressor function and down-regulation in cancer, consisted of Slc27a2, Mall, Snrpb, and Rassf2. All of these genes demonstrated decreased expression in the metastasizing compared to the non-metastasizing NE-10 tumors by quantitative RT-PCR.
