Surprisingly , MF plus ethanol significantly elevated protein expression of medium - chain acyl - CoA dehydrogenase ( MCAD ) , long - chain acyl - CoA dehydrogenase ( LCAD ) and very long chain acyl - CoA dehydrogenase but did not significantly affect mRNA expression of other proteins involved in beta - oxidation and fatty acid synthesis .
