Selection of reference genes for gene expression studies in ultraviolet B-irradiated human skin fibroblasts using quantitative real-time PCR.

ABSTRACT:

Background

Reference genes are frequently used to normalise mRNA levels between different samples. The expression level of these genes, however, may vary between tissues or cells and may change under certain circumstances. Cytoskeleton genes have served as multifunctional tools for experimental studies as reference genes. Our previous studies have demonstrated that the expression of vimentin, one cytoskeletal protein, was increased in ultraviolet B (UVB)-irradiated fibroblasts. Thus, we examined the expression of other cytoskeleton protein genes, ACTB (actin, beta), TUBA1A (tubulin, alpha 1a), and TUBB1 (tubulin, beta 1), in human dermal fibroblasts irradiated by UVB to determine which of these candidates were the most appropriate reference genes.
