Procollagen-lysine, 2-oxoglutarate 5-dioxygenases 1, 2, and 3 are potential prognostic indicators in patients with clear cell renal cell carcinoma

Figure 4. Relationship between transcriptional expressions of distinct PLODs family members and individual cancer stages and pathological grade of ccRCC patients. (AC) Transcriptional expressions of PLOD1, PLOD2 and PLOD3 were significantly correlated with individual cancer stages, patients who were in more advanced stages tended to express higher mRNA expression of PLODs. (DF) Transcriptional expressions of PLOD1, PLOD2 and PLOD3 were significantly correlated with individual pathological grade, patients who were in more advanced grade score tended to express elevated mRNA expression of PLODs. The highest mRNA expressions of PLODs were found in stage 4 or grade 4. *p<0.05, **p<0.01, ***p<0.001. (G) Hierarchical partitioning was performed using transcriptional expression profiles of PLODs in a heat map. Color gradients suggest high (red) or low (blue) expression level, indicating a trend that higher AJCC stage was associated with elevated PLODs expression.
