ALDH1A1 and soft tissue sarcoma: This is in agreement with our survival analysis on soft-tissue sarcomas demonstrating that upregulated expression of ALDH6A1 but not ALDH1A1 or ALDH3A1 significantly correlates with poor survival when combined with other genes identified in our model, i.e., CDH15, MYOD1, SOX4, ARMCX1, and RYK.
