Abstract

Platelets (PLTs) facilitate tumor progression and the spread of metastasis. They also interact with cancer cells in various cancer types. Furthermore, PLTs form complexes with gastric cancer (GC) cells via direct contact and promote their malignant behaviors. The objective of the present study was to explore the molecular mechanisms driving these interactions and to evaluate the potential for preventing peritoneal dissemination by inhibiting PLT activation in GC cells. The present study examined the roles of PLT activation pathways in the increased malignancy of GC cells facilitated by PLT‑cancer cells. Transforming growth factor‑β receptor kinase inhibitor (TRKI), Src family kinase inhibitor (PP2) and Syk inhibitor (R406) were used to identify the molecules influencing these interactions. Their therapeutic effects were verified via cell experiments and validated using a mouse GC peritoneal dissemination model. Notably, only the PLT activation pathway‑related inhibitors TRKI and PP2, but not R406, inhibited the PLT‑enhanced migration and invasion of GC cells. In vivo analyses revealed that PLT‑enhanced peritoneal dissemination was suppressed by PP2. Overall, the present study revealed the important role of the Srk family in the interactions between PLTs and GC cells, suggesting kinase inhibitors as promising therapeutic agents to mitigate the progression of peritoneal metastasis in patients with GC.
