RAB10 and acute myeloid leukemia: Additional studies were performed on AML bone marrow samples; Ping et al. (2019a) identified circ_0009910 as a circRNA that sponged the tumor-suppressor microRNA miR-20a-5p, thus promoting cancer growth, while Fan et al. (2018) reported that circ_100290 promoted AML cell proliferation and inhibited apoptosis by sponging miR-293, ultimately increasing the expression of Rab10, a member of the oncogenic RAS family.
