In this study, eight candidate reference genes were evaluated for RT-qPCR normalization in the drone testis of honey bees (Apis cerana) during meiosis. The goal was to identify stable reference genes across meiosis stages to enable accurate measurement of target gene expression.

Stability assessments were performed using multiple algorithms: BestKeeper, delta-CT, GeNorm, NormFinder, and RefFinder. The ranking of the most stable reference genes varied among methods, but integrating results identified gapdh as the most stable reference gene overall for the drone testis during meiosis.

Additionally, the combination of gapdh and rps18 emerged as an optimal approach for normalization, with both individual gene stability and combined performance supporting their utility. The expression patterns of two target genes, stat92e and dicer1, were used to validate the selected reference genes, confirming that gapdh (and, when used together with rps18, enhanced normalization reliability) provided robust normalization for evaluating target gene expression during meiosis.

The findings establish a foundation for more accurate quantification of gene expression in drone testes across meiosis stages, acknowledging that stability can differ by algorithm.

Clinical Editorial

Reference context and objective

The study addresses normalization for RT-qPCR in the drone testis of the honey bee (Apis cerana) during meiosis stages, aiming to identify stable reference genes for accurate target gene quantification.

Study design and methods

Eight candidate reference genes were evaluated for stability using multiple computational tools: BestKeeper, delta-CT, GeNorm, NormFinder, and RefFinder.
The validation of selected reference genes employed expression patterns of two target genes, stat92e and dicer1, to corroborate stability.

Population and biological scope

The analysis focuses on drone testis throughout meiosis stages in the honey bee species Apis cerana.

Key findings on reference gene stability

Stability rankings varied depending on the algorithm used.
When integrating results across the different algorithms, gapdh emerged as the most stable reference gene for normalization during meiosis stages.
Additional satisfactory reference genes identified include rps18.
The combination of gapdh and rps18 was also deemed optimal for normalization in this biological context.

Validation and practical implications

The stability of gapdh (and the gapdh-rps18 combination) was supported by the expression patterns of stat92e and dicer1, providing practical validation for their use as references.
The results offer a foundation for accurate quantification of gene expression in drone testis across meiosis stages, facilitating downstream molecular analyses in this developmental window.

Contextual notes and limitations

The report emphasizes that optimal reference gene choice can differ by algorithm; thus, integrative selection is recommended.
Explicit limitations or methodological caveats beyond algorithmic variability were not detailed in the provided content.
