Core Tip
Core tip: The activation of the stem cell factor/c-Kit receptor (c-KitR) pathway in mast cells (MCs), and tryptase release upon MCs degranulation have a pivotal role in tumor angiogenesis in several human malignancies. MCs positive to tryptase (MCPT) have been implicated in primary gastric cancer (GC) angiogenesis. Our preliminary findings indicated that bone metastasis angiogenesis from GC is also supported by infiltrating MCPTs. Overall, the evidence provides a rationale to evaluate c-KitR inhibitors that block MCs degranulation, or tryptase inhibitors that inhibit tryptase and/or the Proteinase-Activated Receptor-2 pathway, in clinical trials for bone metastasis GC patients.
