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. The gene discussed is PIM1; the disease is posterior cortical atrophy.
