IFT88 and prostate carcinoma: Using siRNA for intraflagellar transport protein 88 (IFT88) to knockdown osteocyte primary cilia, we found that this disrupted osteocyte mechanosensitivity did indeed abrogate the mechano‐regulated control of breast cancer cell proliferation, as we observed previously.[19] However, no effect on prostate cancer cells was observed (Figure S6B, Supporting Information).
