Other genes in the area include PDGFRB, which plays an important role in tumor neovascularization [43], TGFBI [16], PTTG1, DOCK2 and DUSP1 (the latter three genes were speculated based on our internal studies), which were likely to be involved in ccRCC progression and development. The gene discussed is DUSP1; the disease is nonpapillary renal cell carcinoma.
