PPARG and squamous cell carcinoma: Humanprimary squamous cellcarcinoma, lymph node metastasis, and squamouscell carcinoma cell lines express high levels of PPARγ [69].The specific PPARγ antagonists T0070907, GW9662, andBADGE, but not agonists (i.e., pioglitazone and rosiglitazone) induced apoptosisin squamous cell carcinoma cell lines by interfering with adhesionto the extracellular matrix and disrupting survival signals, andthus inducing anoikis.
