This difference in the estimated expression status of TOB1-2 has potentially important biological implications because TOB1 is a tumor suppressor (Kundu et al. 2012), and in gastric cancer cells, miR-25 represses TOB1 by binding to a 3′-UTR region that is present in TOB1-1 but absent in TOB1-2 (Li et al. 2015). Here, TOB1 is linked to gastric cancer.
