Abstract

Semaphorin 4A (SEMA4A) belonged to a family of membrane-bound proteins that were initially recognized as a kind of axon guidance factors in nervous system. It was preferentially expressed on immune cells and has been proven to play a prominent role in immune function and angiogenesis. In this study, we found that SEMA4A was highly expressed in prostate cancer (PCa) tissues and correlated with Gleason scores and distant metastasis. SEMA4A could induce Epithelial-mesenchymal transition (EMT) of PCa cells and consequently promote invasion by establishing a positive loop with IL-10 in stromal cells. experiments showed more dissemination in mice injected with SEMA4A-overexpressing cells in mouse models and both the number and size of lung metastases were significantly increased in SEMA4A-overexpressing tumors. SEMA4A depletion by genetic means prevents lung metastasis in PCa xenograft models. Our data suggest a crucial role of SEMA4A in PCa and blocking SEMA4A-IL-10 axis represents an attractive approach to improving therapeutic outcomes.
