Influence of Age on Cerebral Housekeeping Gene Expression for Normalization of Quantitative Polymerase Chain Reaction after Acute Brain Injury in Mice
2015
To prevent methodological errors of quantitative PCR (qPCR) normalization with reference genes is obligatory. Although known to influence gene expression, impact of age on housekeeping gene expression has not been determined after acute brain lesions such as traumatic brain injury (TBI). Therefore, expression of eight common control genes was investigated at 15 min, 24 h, and 72 h after experimental TBI in 2- and 21-month-old C57Bl6 mice. Expression of β2-microglobulin (B2M), β-actin (ActB), and porphobilinogen deaminase (PBGD) increased after TBI in both ages. β2M demonstrated age-dependent differences and highest inter- and intragroup variations. Expression of cyclophilin A, glyceraldehyd…
Selection of endogenous control genes for normalization of gene expression analysis after experimental brain trauma in mice.
2008
Quantitative measurements of gene expression require correction for tissue sample size, RNA quantity, and reverse transcription efficiency. This can be achieved by normalization with control genes. The study was designed to identify candidates not altered after brain trauma. Male C57Bl/6 mice were anesthetized with isoflurane, and a pneumatic brain trauma was induced by controlled cortical impact (CCI) on the right parietal cortex. Brains were removed at 15 min, and 3, 6, 12 and 24 h after CCI and from naive animals (n = 6 each). Absolute copies of six control genes (beta-2-microglobin [B2M], cyclophilin A, beta-actin, hypoxanthine ribosyltransferase [HPRT], porphobilinogen deaminase [PBGD]…
