Another interesting report draws attention to the PPAR-γ status in primary NSCLC tissues, highlighting that the expression level of PPARG in lung tumours is usually considerably higher in comparison to corresponding histopathologically unchanged samples, however, this intratumoural PPARG overexpression does not exhibit an anticarcinogenic/protective effect because of the lack of PPAR-γ agonists [43, 44]. Here, PPARG is linked to non-small cell lung carcinoma.
