GPCPD1 and renal cell carcinoma: Specifically, Huang et al. [58] found that circSNX6 promoted sunitinib resistance in RCC by suppressing the inhibitory effect of miR-1184 on its target gene, GPCPD1, and increasing intracellular lysophosphatidic acid (LPA) levels. Tan et al. [59] showed that circRNA-001895 expression in sunitinib-resistant RCC was higher than that in chemotherapy-sensitive tissues.
