This practice is being questioned as it becomes increasingly clear that the level of housekeeping genes expression may vary considerably in certain biological samples. To date, the validation of reference genes in aging has received little attention and suitable reference genes have not yet been defined. Our aim was to evaluate the expression stability of frequently used reference genes in human peripheral blood mononuclear cells with respect to aging. Using quantitative RT-PCR, we carried out an extensive evaluation of five housekeeping genes, i.e. 18s rRNA, [[ACTB]], [[GAPDH]], [[HPRT1]] and [[GUSB]], for stability of expression in samples from donors in the age range 35-74 years. The consistency in the expression stability was quantified on the basis of the coefficient of variation and two algorithms termed geNorm and NormFinder. Our results indicated [[GUSB]] be the most suitable transcript and 18s the least for accurate normalization in PBMCs. We also demonstrated that aging is a confounding factor with respect to stability of 18s, [[HPRT1]] and [[ACTB]] expression, which were particularly prone to variability in aged donors.<br /> |mesh-terms=* Adult<br /> * Aged<br /> * Aging<br /> * Algorithms<br /> * Gene Expression<br /> * Genes<br /> * Humans<br /> * Hypoxanthine Phosphoribosyltransferase<br /> * Leukocytes, Mononuclear<br /> * Middle Aged<br /> * RNA, Messenger<br /> * Reference Standards<br /> * Reproducibility of Results<br /> * Reverse Transcriptase Polymerase Chain Reaction<br /> <br /> |full-text-url=https://sci-hub.do/10.1016/j.mad.2009.12.005<br /> }}</div>
