ALDH1A1 and neoplasm: The top differentially expressed transcripts between tumor and non-tumor were TPX2, DCBLD2 and ANLN which were significantly increased in tumors (T∶N ratio>2.0, P<0.01), and CDO1, DPEP1, C7, ALDH1A1 and NR3C2 which were significantly decreased in tumors (T∶N ratio<0.2, P<0.01).
