Many of the commonly used HKGs are regulated and vary under experimental conditions and disease stages. Alcoholic liver disease (ALD) is associated with several different liver histological lesions that may modulate HKG expression. We investigated the variability of commonly used HGKs (18S, \u03b2\u2010actin, glyceraldehyde\u20103\u2010phosphate [GAPDH], and arginine\/serine\u2010rich splicing factor [SFRS4]) in the liver of patients with ALD.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:\u2002<\/jats:bold>\n                    Fifty consecutive patients at different stages of ALD underwent liver biopsy.

GAPDH and SFRS4 COD were 2.8 and 2.1, respectively. GAPDH was decreased with steatosis and increased with alcoholic hepatitis and fibrosis. 18S had the lowest COD (1.4). Both 18S and SFRS4 levels were not significantly modified with respect to all alcohol\u2010induced liver histological lesions.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:\u2002<\/jats:bold>\n                    In patients with ALD, the most constantly expressed HKGs are 18S and SFRS4. These genes are appropriate reference genes for normalization of RT\u2010qPCR in the liver of patients with ALD. The use of other HKGs such as \u03b2\u2010actin or GAPDH would lead to misinterpretation of the results.\n
