Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in children and adults. This study examined the relationship between hepatic nuclear receptor (NR) expression and histologic features of NAFLD. Drugs targeting a variety of NRs for nonalcoholic steatohepatitis (NASH) are in clinical trials. Liver messenger RNA was isolated from 40 children (10-19 years) undergoing end-of-treatment biopsy in the Treatment of NAFLD in Children (TONIC) trial. High-throughput quantitative polymerase chain reaction assayed NR messenger RNA. Cluster analysis was used to group 36 NRs, and NR levels were related to histologic measures of specific NAFLD features. Cluster analysis determined five groupings of NRs. Significant (P < 0.05) differential expressions of specific NRs associated with histologic measures include farnesoid X receptor alpha and retinoic acid receptor (RAR beta and RAR beta) for steatosis; estrogen receptor alpha (ER alpha) and peroxisome proliferator-activated receptor gamma 3 (PPAR gamma 3) for hepatocellular ballooning; ER and PPAR gamma 2 for lobular inflammation; PPAR alpha/delta/gamma 1/gamma 2, ER alpha, constitutive androstane receptor, chicken ovalbumin upstream promoter transcription factor 1, RAR alpha, RAR beta 1, retinoid X receptor, pregnane X receptor, thyroid hormone receptors a and beta, and nuclear receptor related-1 for fibrosis; and ER alpha and RAR beta/beta 1/alpha for diagnosis of NASH. Conclusion: Differential expression of specific NRs correlates with histologic severity of specific NAFLD features. These NRs are pleiotropic transactivators regulating basal metabolic functions and inflammatory responses. Derangement of activity of these receptors in NAFLD provides a rationale for exploiting their ability with receptor-specific ligands to ameliorate NASH and its consequences.
