Identificazione di geni di normalizzazione per studi trascrizionali con Polymerase Chain Reaction
Identification of genes for normalization of RT-qPCR gene expression data: a review of published literature
<p>Reverse-transcriptase quantitative Polymerase Chain Reaction (RT-qPCR) is a well-established technique to quantify gene expression levels and critically depends on reference genes for data normalization.<br />We performed a review of biomedical literature to analyse the usage of RT-qPCR in relation to other techniques for transcriptional analyses and to describe practices for the identification of suitable reference genes for RT-qPCR.<br />In the 81 analysed studies, 3 genes (GAPD, ACTB, B2M) were included in &ge;70% of cases, but ranked among the most stable genes in &le;1/3 of cases. The most frequently used normalizing algorithm was geNorm(83%), followed by NormFinder(73%) and BestKeeper(32%).<br />We also analysed transparency and good laboratory practices based on adherence to the Minimum Information for Publication of Quantitative Real-Time PCR Experiments (MIQE) guidelines, using selected validated evaluation criteria. Overall, key MIQE criteria were satisfied in &ge;50% of analyzed studies, but only four criteria (details of employed kit/enzyme for reverse transcription, priming method, primers/probes and DNA polymerase) were satisfied in &ge;90% of cases. Data on assay repeatability were reported only in 15% of studies. The presence of pseudogenes as a potential confounder of assay specificity was evaluated only in 13% of studies. Finally, as few as 6% of studies accounted for the presence of known mutations of singly nucleotide polymorphisms when designing assay primers/probes.<br />Better adherence to the MIQE guidelines should be encouraged. Publicly available transcriptomic and genomic data sets could be employed to refine the identification of suitable normalizing genes and to assist assay design.</p>

Analisi dei livelli trascrizionali di ciclina D1 nello studio delle discrasie plasmacellulari: revisione sistematica della letteratura
Analysis of cyclin D1 mRNA expression levels in plasma cell dyscrasias: a systematic review of published literature
<p>Overexpression of cyclin D1 (CCND1) occurs often in tumoral plasma cells, mainly &ndash; but not exclusively &ndash; as a result of the presence of the t(11;14) translocation. Of note, CCND1 mRNA overexpression or the presence of the t(11;14) translocation was shown to impact on the response to anti-plasma cell drugs and influence prognosis, both in patients with multiple myeloma and with immunoglobulin light chain (AL) amyloidosis. In this study, we performed a systematic revision of published literature on molecular assays to measure CCND1 transcript levels in plasma cell dyscrasias, in order to describe currently available assays, their technical characteristics and main applications. Relevant scientific articles were search on PubMed as of October 2020 using combinations of appropriate key words. Of 165 unique studies retrieved, 11 articles fulfilled the inclusion criteria and were further analyzed. Overall, 8 different molecular assays were described and characterized. Most of the studies focused on multiple myeloma, with some studies including also MGUS, plasma cell leukemia and/or AL amyloidosis. Assay design, technical validation and field of application of each assay were systematically reviewed. As more knowledge is gained about the impact of CCND1 expression levels on the biology of tumoral plasma cells and their response to anti-plasma cell drugs, including novel agents specifically targeting t(11;14)-positive clones, molecular assays to quantify CCND1 expression levels in tumoral plasma cells may become a useful complementation to molecular cytogenetics, towards a precision medicine approach to diagnose and treat plasma cell disorders which is based on laboratory medicine.</p>
