ALDH1A1 and neoplasm: We further checked the protein expression of TRIB3, ALDH1A1, and c-MYC in lysates of xenografted tumors and results showed that TRIB3 was slightly decreased in the only one small engrafted tumor of TRIB3-knockdown AN3CA cells, while the expression levels of ALDH1A1 and c-MYC were greatly reduced (Figure 4e).
