Furthermore, PIM1 has been observed to enhance MYC‐induced tumorigenicity in human PCa in a mouse xenograft model,17 while coexpression of PIM1 and MYC in human PCa is associated with higher Gleason scores, suggesting that these oncoproteins synergize to induce advanced prostate carcinoma.17, 18. This evidence concerns the gene PIM1 and prostate carcinoma.
