Active RANK expression allows for Ca2+ release from ER dependent on PLCγ-mediated IP3R and Ca2+ influx from the extracellular milieu through STIM1-regulated SOCE. Besides, PLCγ-mediated IP3R axis act upstream of STIM1 to coactivate Ca2+ oscillation. The Ca2+ oscillation in the cytoplasm leads to calcium-dependent calcineurin activation and NFATC1 transcription of osteoclast-specific gene, ACP5, which promotes CRC metastasis.
