Considering the association of increased fructose intake with the rise in
metabolic syndrome and gender differences in its incidence, this study was
aimed at evaluating and identifying the optimal reference genes for the
relative quantification of gene expression by real-time PCR in the adipose
tissue of female rats exposed to a fructose-enriched diet as an animal model
of metabolic syndrome. The transcription of four commonly used reference
genes, BA, HPRT1, TBP and B2M, was quantified by TaqMan real-time PCR. The
expression stability of these genes was evaluated by direct comparison of Ct
values and by using the geNorm and NormFinder algorithms. NormFinder revealed
HPRT1 as the most stable gene, and both programs identified HPRT1 and TBP as
the most stable combination of genes in this experimental paradigm. In
addition, HPRT1 was shown to be reliable enough as the sole reference gene.
