Analysis by western-blot of protein lysates showed a dramatic overexpression of both eIF4E and eIF2 in liposarcomas arisen both in FUS-DDIT3 mice and human liposarcomas cell lines FUS-DDIT3 positives (Figure 6A), explaining the shift towards the truncated p30 isoform of C/EBPα in liposarcomas. The gene discussed is EIF4E; the disease is liposarcoma.
