Identification of reference genes for quantitative PCR analyses in developing mouse gonads

Area of Science:

• Developmental Biology
• Molecular Biology
• Genetics

Background:

• Accurate gene expression analysis, particularly using quantitative PCR (qPCR), relies on the selection of stable reference genes.
• Identifying reliable reference genes is critical for studying gene expression in developing mouse gonads, a complex biological process.

Purpose of the Study:

• To systematically evaluate the stability of 15 candidate reference genes in developing mouse gonads.
• To identify the most suitable reference genes for accurate gene expression analysis across different developmental stages and genders.

Main Methods:

• Utilized multiple algorithms to assess the expression stability of 15 candidate reference genes.
• Analyzed gene expression fluctuations based on developmental period and gender in mouse gonads.

Main Results:

• Significant variations in gene expression were observed for most candidate genes, influenced by developmental timing and gender.
• Peptidylprolyl isomerase A (Ppia) and polymerase (RNA) II (DNA directed) polypeptide A (Polr2a) emerged as the most stable reference genes over a broad analysis period.
• Rankings of stable reference genes were provided, specific to developmental period and/or gender.

Conclusions:

• The choice of reference gene is critical and must be validated for specific experimental conditions in developing mouse gonads.
• Ppia and Polr2a are recommended as reliable reference genes for broad applications, while period/gender-specific options offer enhanced precision.
