Identification of optimal reference genes for gene expression studies in a focal cerebral ischaemia model-Spatiotemporal effects.

ABSTRACT: A proper reference gene (RG) is required to reliably measure mRNA levels in biological samples via quantitative reverse transcription PCR (RT-qPCR). Various experimental paradigms require specific and stable RGs. In studies using rodent models of brain ischaemia, a variety of genes, such as β-actin (Actb), hypoxanthine phosphoribosyltransferase 1 (Hprt1), peptidyl-propyl isomerase A (Ppia) and glyceraldehyde-3-phosphate dehydrogenase (Gapdh), are used as RGs. However, most of these genes have not been validated in specific experimental settings. The aim of this study was to evaluate the time- and brain region-dependent expression of RG candidates in a rat model of transient middle cerebral artery occlusion (tMCAO). The following genes were selected: Actb, Hprt1, Ppia, Gapdh, tyrosine 3-mon
