DLK2 and nonpapillary renal cell carcinoma: In addition, the expressions of branched chain keto acid dehydrogenase E1 subunit β (BCKDHB) (r = −0.4698, p = 1.293 × 10−30), pleckstrin homology domain containing B2 (PLEKHB2) (r = −0.4499, p = 6.472 × 10−28), GTP binding elongation factor GUF1 (GUF1) (r = −0.447, p = 1.51 × 10−27), adenosine deaminase like (ADAL) (r = −0.4282, p = 3.533 × 10−25), and ELMO domain containing 2 (ELMOD2) (r = −0.4245, p = 9.855 × 10−25) were highly and negatively correlated to the DLK2 levels in the ccRCC tumors (Figure 7).
