However, ALDH1L1 showed totally different presentation in distinct types of cancers; mRNA high expressions of ALDH1L1 were reported to be correlated to higher overall survival rate for breast cancer patients but were revealed as a poor prognostic factor in gastric and prostatic cancers (Prakasam et al., 2014; Wu et al., 2015; Ren et al., 2016). This evidence concerns the gene ALDH1L1 and prostate carcinoma.
