Abstract


Housekeeping genes, by definition and function, should be constitutively and stably expressed in all cells of the organism, regardless of the cell type and function they accomplish. However, it was observed that expression of housekeeping genes, used as reference genes in gene expression analysis, varies greatly in different cells and tissue types and is also dependent on the experimental conditions and treatments. The aim of our study was to examine the expression patterns of the most frequently used reference genes (GAPDH, ACTB and RRN18S) in the samples of human subcutaneous adipose tissue (scWAT) and benign adipose tissue tumors (lipomas). The obtained results have shown that the expression of all three examined housekeeping genes is slightly lower in lipoma samples compared to scWAT samples and that GAPDH is the most stable housekeeping gene in examined samples so it can be recommended as an optimal reference gene for gene expression analysis in human scWAT and lipoma samples.
