TRPCs are cation channels, mainly permeable to Ca2+ ions. TRPC6 plays a crucial role in tumor development. TRPC3 controls fibronectin expression, thereby regulating wound healing process. TRPC7 is involved in the proliferation of osteoblasts.
PPZ2 selectively activates DAG-activated TRPC3/TRPC6/TRPC7 channels. PPZ2 activates native TRPC6-like channels in smooth muscle cells isolated from the rabbit portal vein. PPZ2 induces BDNF-like neurite growth and neuroprotection in cultured neurons.
