With regards to chronic myeloid leukemia, a lncRNA, BGL3, was found to act as a ceRNA and cross-control PTEN expression by sponging six miRNAs (miR-106a, miR-93, miR-106b, miR-20a, miR-17, and miR-20b) [25]. The gene discussed is PTEN; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
