Previously, for another tumor type, e.g., clear cell renal cell carcinoma, Zhang et al. [32] presented high LTB4R expression as an important cancer marker and possibly a highly specific target associated with a poor prognosis due to the promotion of cancer cell proliferation, migration, development, and progression via the Akt/mTOR pathway. The gene discussed is LTB4R; the disease is clear cell renal carcinoma.
