COPS5 and carcinoma: Cancer is a progressive disease which usually results from genomic instability that could be caused by chromosomal translocations, which leads to aberrant expression of oncogenes, such as Jab1/COPS5 or MYC. Here we searched the GEPIA database (http://gepia.cancer-pku.cn/index.html) to systematically assess the differential expression of Jab1 in a variety of carcinomas.
