SOX12 and renal cell carcinoma: Hsa_circ_001895 is upregulated in RCC specimens; knocked down hsa_circ_001895 can inhibit RCC progression and promote apoptosis by reducing the adsorption of miR-296-5p and decreasing the expression of sex-determining region Y (SRY)-box 12 (SOX12) (Chen et al., 2020).
