Gouble et al. [30] examined transgenic mice that overexpressed p37AUF1 (HNRNPD), and found that they overexpressed the mRNAs for multiple tumor-associated genes, including c-Myc, c-Jun, c-Fos, granulocyte macrophage colony-stimulating factor, tumor necrosis factor-α and cyclin D1, resulting in the spontaneous formation of soft tissue sarcoma. Here, JUN is linked to soft tissue sarcoma.
