Furthermore, blockading potential PGI(2) receptors, including immunoprecipitation (IP) receptors and peroxisome proliferator-activated receptors alpha (PPAR alpha) and delta, revealed that siRNA-mediated blockage of PPAR alpha considerably reduced the anti-proliferation effect of L-carnitine.
The authors used the luciferase reporter assay and Western blot analysis to determine COX-2 induction by Cr(VI); dominant negative mutant, genetic knockout, gene knockdown, and chromatin immunoprecipitation approaches were used to elucidate the signaling pathway leading to COX-2 induction.
