Data supporting the design and evaluation of a universal primer pair for pseudogene-free amplification of HPRT1 in real-time PCR.

ABSTRACT: Hypoxanthine-guanine phosphoribosyltransferase 1 (HPRT1) is a common housekeeping gene for sample normalization in the quantitative reverse transcriptase polymerase chain (qRT-PCR). However, co-amplification of HPRT1 pseudogenes may affect accurate results obtained in qRT-PCR. We designed a primer pair (HPSF) for pseudogene-free amplification of HPRT1 in qRT-PCR [1]. We showed specific amplification of HPRT1 mRNA in some common laboratory cell lines, including HeLa, NIH/3T3, CHO, BHK, COS-7 and VERO. This article provides data supporting the presence and location of HPRT1 pseudogenes within human and mouse genome, and the strategies used for designing primers that avoid the co-amplification of contaminating pseudogenes in qRT-PCR. In silico analysis of human genome showed three homologous sequences for HPRT1 on chromosomes 4, 5 and 11. The mRNA sequence of HPRT1 was aligned with the pseudogenes, and the primers were designed toward 5' end of HPRT1 mRNA that was only specific to HPRT1 mRNA not to the pseudogenes. The standard curve plot generated by HPSF primers showed the correlation coefficient of 0.999 and the reaction efficiency of 99.5%. Our findings suggest that HPSF primers can be recommended as a candidate primer pair for accurate and reproducible qRT-PCR assays.

Project description:Ribosomal DNA has been a reliable source of taxonomic and phylogenetic markers due to its high copy number in the genome and stable variation with few polymorphisms due to the homogenizing effect of concerted evolution. Typically specific regions are amplified through polymerase chain reaction (PCR) with multiple primer pairs that generate often incomplete and overlapping regions between adjacent segments of 18S, ITS1, 5.8S, ITS2, and 28S rDNA nucleotide sequences when combined in tandem. To improve the efficiency of this effort, a strategy for generating all these molecular sequences at once through PCR amplification of a large ribosomal 3.3 to 4.2?kb DNA target was developed using primer 18S-CL-F3 paired with D3B or a new alternative 28S PCR primer (28S-CL-R) and other well-positioned and ribosomal-specific sequencing primers (including novel primers 18S-CL-F7, 18S-CL-R6, 18S-CL-R7, 18S-CL-F8, 5.8S-CL-F1, 5.8S-CL-R1, 28S-CL-F1, 28S-CL-R3, 28S-CL-F3, 28S-CL-R1, and 28S-CL-F2). The D1 region between ITS2 and 28S boundaries and the flanking sequence between 18S and ITS1 boundaries were fully revealed in this large nucleotide segment. To demonstrate the value of this strategy, the long rDNA segment was amplified and directly sequenced in 17 agriculturally important nematodes from the Tylenchida, Aphelenchida, and Dorylaimida. The primers and their positions may be employed with traditional Sanger sequencing and with next-generation sequencing reagents and protocols.Ribosomal DNA has been a reliable source of taxonomic and phylogenetic markers due to its high copy number in the genome and stable variation with few polymorphisms due to the homogenizing effect of concerted evolution.
