Taken together with the effect of TAZ knockdown only in the viability and proliferation of D17 cells, these results suggest that TAZ effects of OSA cells were specific to metastasis-derived cell lines, and whether or not active TGFβ signaling modulates the effect that TAZ or YAP has in OSA cell migration is cell line dependent. The gene discussed is TGFB1; the disease is obstructive sleep apnea syndrome.
