PPAR-α is highly expressed in the liver, heart, kidney, muscle, brown adipose tissue, and gut tissues which exhibit high carbolic rates towards fatty acid.8 PPAR-β is expressed ubiquitously, and its function is relatively unknown.9 Recent studies suggest that PPAR-β may be a target for NSAID-induced tumor suppression in colorectal tumors. The gene discussed is PPARD; the disease is neoplasm.
