PPARA and non-small cell lung carcinoma: NSCLC cell lines (H157 and H2122) were transiently transfected with either an empty vector or a panel of constitutively active Gα subunits of G-proteins (Gαi2Q205L, GαoQ205L, GαqQ209L, GαzQ205L, Gα12Q229L, or Gα16Q212L) together with a PPAR-Response Element (RE) luciferase reporter vector.
