Sıçanlarda Dokuya Özel Referans Genler: Kardiyak, Kas ve İskelet Sistemlerine Bakış

Öz

mRNA ekspresyon çalışmalarında doğru normalizasyon, stabil referans genlerin seçilmesine bağlıdır. Bu derleme, normal ve çeşitli deneysel koşullar altında sıçan modellerinde kalp, kas ve kemik dokuları arasında referans gen önerilerini ortaya koymaktadır. 2000-2024 yılları arasında bildirilen çalışmalar, erkek sıçanların daha sık kullanıldığını ve Wistar ve Sprague-Dawley sıçanlarına odaklandığını göstermektedir. Çalışmalar sonucunda, sık kullanılan referans genlerin (GAPDH ve ACTB gibi) sınırlılıkları olduğu kanıtlanmıştır. geNorm, NormFinder ve BestKeeper gibi gelişmiş algoritmalar, stabilite kavramını belirlemekte ve kullanıcılar için serbestçe kullanılabilir durumdadır. Çalışmalar, referans gen seçiminde bölgesel ve zamansal faktörlerin önemini vurgulamaktadır. Ayrıca, cinsiyet ve gelişimsel aşama farklılıkları sıklıkla göz ardı edilmiştir ve bu anlamda literatürde hala bir boşluk vardır. Bu derleme, RT-PCR çalışmalarında güvenilirliği ve tekrarlanabilirliği sağlamada referans genlerin kritik rolünün altını çizmektedir. Farklı hastalık modellerinde normalizasyon için referans genlerin stabilitesine ve seçimine katkıda bulunacaktır. 12 öncü çalışmadan elde edilen bulguların sentezlenmesi, belirli dokular ve deneysel koşullar için sağlam referans genlerin seçilmesi için mevcut verileri sağlayarak, mRNA ekspresyon çalışmalarında gen ekspresyonunun doğru yorumlanmasına katkıda bulunacaktır.

Tissue-Specific Reference Genes in Rats: Insights into Cardiac, Muscular, and Skeletal Systems

Öz

Correct normalization in mRNA expression studies depends on selecting stable reference genes. This review reveals reference gene suggestions among cardiac, muscle, and bone tissues in rat models under normal and various experimental conditions. Studies reported between 2000-2024 show that male rats were used more frequently and focused on Wistar and Sprague-Dawley rats. As a result of the studies, it has been proven that frequently used reference genes (such as GAPDH and ACTB) have limitations. Advanced algorithms such as geNorm, NormFinder, and BestKeeper determine the concept of stability and are freely available to users. Studies emphasize the importance of regional and temporal factors in reference gene selection. Moreover, gender and developmental stage differences have often been overlooked, and there is still a gap in the literature in this sense. This review underlines the critical role of reference genes in ensuring reliability and reproducibility in RT-PCR studies. It will contribute to the stability and selection of reference genes for normalization in different disease models. Synthesizing the findings from 12 pioneering studies will contribute to the accurate interpretation of gene expression in mRNA expression studies by providing existing data for selecting robust reference genes for specific tissues and experimental conditions.
