LGALS1 and neoplasm: We found that the levels of LGALS1 transcripts were significantly lower in tumor tissues than in the normal urothelium in KSCGMH cohort (p < 0.001; Figure 1A); however, this trend was not observed in the TCGA cohort (p = 0.74; Figure 1B); the difference in trend was possibly attributable to the small number of normal tissue samples (n = 19) in the TCGA cohort.
