All animal studies were performed in the Laboratory Animal Center of Sun Yat-sen University and conducted in accordance with the institutional policies for animal care. Approximately 5 x 10⁶ MMQ_vector cells or MMQ_circOMA1 cells in 150 uL were injected into the right flank of BALB/c nude mice (total of 12 female mice, 4-6 weeks, SCXK2021-0029). After tumor formation (10 days), mice were randomly divided into four groups (n = 3 mice/group) as follows: vector (saline solution, intraperitoneally injected), circOMA1 (saline solution, intraperitoneally injected), vector + CAB (0.5 mg/kg, intraperitoneally injected), and circOMA1 + CAB (0.5 mg/kg, intraperitoneally injected) in accordance with previous studies. CAB was injected intraperitoneally every 2 days for 14 days. The size of the tumor was measured every 3 days. On Day 15, mice were anesthetized with 0.3% pentobarbital sodium solution and then sacrificed by cervical dislocation, and the xenograft tumors were removed and weighed.
