GNAT3 and hepatocellular carcinoma: Compression of metabolic profile of HCC (n=40) versus cirrhosis (n=49) led to identification of decrease of GCA, GDCA, GCDCA, oleyol carnitine, 3beta, 6betadihydroxy- 5beta-cholan-24- oic acid and up regulation of Phe-Phe (48).  In a biochemical study on urine, it has been suggested disruption of primary and secondary steps of bile acid biosynthesis  in HCC patients (49).
