To further explore the molecular mechanism about how lncRNA TRAF3IP2-AS1 contribute to the progression phenotype of NONO-TFE3 tRCC cells, we first analyzed the RNA sequences of TRAF3IP2-AS1 using the Encyclopedia of RNA Interactomes (ENCORI) (http://starbase.sysu.edu.cn/) [28]. This evidence concerns the gene PTGDR and renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions.
