PG - 305-313 LID - 10.3727/096504016X14666990347437 [doi] AB - Tumor necrosis factor-alpha (TNF-alpha)-induced protein 8-like 2 (TNFAIP8L2, TIPE2) is involved in the invasion and metastasis of human tumors. However, the functional role of TIPE2 in prostate cancer remains unclear. In the present study, we explored the role of TIPE2 in prostate cancer and cancer progression including the molecular mechanism that drives TIPE2-mediated oncogenesis. Our results showed that TIPE2 was lowly expressed in human prostate cancer tissues and cell lines. In addition, restored TIPE2 obviously inhibits proliferation in prostate cancer cells. TIPE2 overexpression also suppresses the epithelial-mesenchymal transition (EMT) process and migration/invasion in prostate cancer cells. Mechanistically, TIPE2 overexpression obviously inhibits the phosphorylation levels of phosphatidylinositol 3-kinase (PI3K) and Akt in prostate cancer cells. In conclusion, for the first time we demonstrated that TIPE2 overexpression may suppress proliferation, migration, and invasion in prostate cancer cells by inhibiting the PI3K/Akt signaling pathway. Therefore, TIPE2 might serve as a potential therapeutic target for human prostate cancer.
