PLOD2 and nonpapillary renal cell carcinoma: Additionally, a strong correlation was detected between PLOD2 and DCLK1-L in the tumor samples of this ccRCC cohort (r = 0.7640, p = 0.0009, Fig. 7B), which was further supported by significant coexpression of PLOD2 and DCLK1 isoform 1 (Fig. 7C) and isoform 2 (Fig. 7D) in the TCGA ccRCC cohort.
