Determination of internal control for gene expression studies in equine tissues and cell culture using quantitative RT-PCR.
Abstract: Quantitative reverse transcription polymerase chain reaction (RT-PCR) has become a basic, reliable and sensitive modern technique, in both biological research and clinical diagnosis, for investigation of gene expression and validation of cDNA microarray analysis. Accurate mRNA quantification using quantitative RT-PCR commonly requires data normalization through stable housekeeping genes (HKGs). Selection of HKGs for data normalization is critical for accurate mRNA quantification. Our objective was to evaluate a set of candidate HKGs as internal controls for gene expression studies using quantitative RT-PCR in equine tissues and cell culture. One-step quantitative RT-PCR for 6 HKGs was performed using total RNA from equine tissue samples and cultured peripheral blood mononuclear cells (PBMCs). The stability of HKGs was mainly evaluated by analysis of variance, analyses of the standard deviation and coefficient of variation of Ct, and change of Ct of HKGs between control and treated samples. 18S rRNA consistently showed the smallest standard deviation and coefficient of variation, and the least change of Ct between control and treated samples, thus was identified as the most stable HKG for mRNA data normalization in quantitative RT-PCR for studying gene expression in equine tissues and cultured PBMCs.

This research article focuses on finding the most reliable internal controls for gene expression studies in equine tissues and cell cultures through the use of quantitative reverse transcription polymerase chain reaction (RT-PCR). The study identifies 18S rRNA as the most stable housekeeping gene, thus making it suitable for data normalization in this context.
Objective and Methodology
- The research aimed to identify a suitable set of housekeeping genes (HKGs) as internal controls for accurate mRNA quantification in equine tissues and cell culture gene expression studies using RT-PCR.
- The candidate HKGs were evaluated through a one-step quantitative RT-PCR process, applied to total RNA extracted from equine tissue samples and cultured peripheral blood mononuclear cells (PBMCs).
Evaluation of Housekeeping Genes
- Housekeeping genes considered for the study were evaluated based on several criteria such as their stability—which was assessed through analysis of variance, standard deviation analyses, coefficient of variation of Ct, and change of Ct of HKGs between control and treated samples.
- The selection process was determined by identifying the gene that showed minimum changes, relating to these measures, between the control and treated samples.
Study Findings
- The study revealed that 18S rRNA was the most stable HKG, as it demonstrated the smallest standard deviation and coefficient of variation, and the least change of Ct between control and treated samples.
- Based on these results, the study concluded that 18S rRNA is the most suitable for mRNA normalization during quantitative RT-PCR for studying gene expression in equine tissues and cultured PBMCs.
Study Implications and Significance
- The accurate selection of housekeeping genes as internal controls is crucial for precise mRNA quantification, as this affects the validity of gene expression studies. Incorrect normalization can lead to misinterpretation of results.
- By identifying 18S rRNA as a reliable HKG in studies using equine tissues and cultured PBMCs, the study contributes to enhancing the accuracy of gene expression analysis in these contexts.
- Such findings may play a crucial role in both biological research and clinical diagnostic processes, improving their overall reliability and validity.
