Transcriptome analysis and prognosis of ALDH isoforms in human cancer.

ABSTRACT: Overexpression of ALDH is associated with cancer stem-like features and poor cancer prognosis. High ALDH activity has been observed in cancer stem-like cells. There are a total of 19 human ALDH isoforms, all of which are associated with reducing oxidative stress and protecting cells from damage. However, it is unknown whether all ALDHs are associated with poor cancer prognosis and which ones play a significant role in cancer progression. In this study, we used RNA sequencing data from The Cancer Genome Atlas (TCGA) to evaluate the differential expression of 19 ALDH isoforms in 5 common human cancers. The 19 ALDH genes were analyzed with an integrating meta-analysis of cancer prognosis. Genotyping and next-generation RNA sequencing for 30 pairwise samples of head and neck squamous cell carc
