In experimental research using mice, 18S rRNA, glyceraldehyde-3-phosphate dehydrogenase (Gapdh) or beta-actin (Actb) 7 are most frequently used as single reference genes. Histological evidence: housekeeping genes beta-actin and GAPDH are of limited value for normalization of gene expression. Housekeeping genes are usually expressed quite regularly and often are not changed by treatment protocols. Some of the housekeeping genes commonly used as expression controls include glyceraldehyde-3-phosphate dehydrogenase (GAPDH), β-actin, β2-microglobulin, cyclooxygenase 1, hypoxanthine phosphoribosyl transferase 1, glucose-6-phosphate dehydrogenase, cyclophilin A, tubulin, transferrin receptor and 18S ribosomal RNA,. β-actin has been frequently used as an internal control (gene) or as a housekeeping gene to normalize the expression of the target gene (s) or mRNA levels between different samples. The utility of 18S rRNA, β-actin mRNA and GAPDH mRNA as housekeeping genes for normalization of gene expression, estimated as mRNA level, was investigated. However, it is well documented that β-actin and GAPDH Accepted: 28 September 2012. Several mutations in the ACTB gene have been found to cause Baraitser-Winter syndrome, a rare condition that affects the development of the brain, eyes, and other facial features. levels has led to the common use of β-actin and GAPDH housekeeping genes as denominators for com-parison of samples. https://www.spandidos-publications.com/10.3892/ijmm.2014.2040 Q-RT-PCR cycle threshold values for 7 candidate housekeeping genes among 31 adult human reticulocyte samples. This is one of the However, the β-actin expression has been shown to be influenced by the sample type and experimental conditions. Schistosomiasis japonica, caused by Schistosoma japonicum infection, continues to be a significant health problem that leads to human morbidity and mortality, especially in lake and marshland regions of China, the Philippines, and Sri Lanka, as well as the area near Lindu Lake (Barsoum et al., 2013; Colley et al., 2014). Beta-actin can be used as a reference gene to normalize mRNA or protein levels in quantitative studies of expression. Although some evidence suggests variation in tissue types and developing embryos (PMID: 23099774) if expression is stable across conditions, beta-actin is still considered by many to be a suitable gene for normalization. Gene provides a unified query environment for genes defined by sequence and/or in NCBI's Map Viewer.

These genes were selected based on expression stability from data collected from more than 25 experimental conditions in various CHO cell lines using our custom microarray platform. GAPDH is a key regulatory enzyme, which catalyzes the oxidative phosphorylation of glyceraldehyde-3-phosphate during glycolysis. The average cellular expression levels of mRNA for IL-2, IL-4, IL-10, IFN-γ, TNF-α and TGF-β1 were determined in freshly isolated PBMCs and PBMCs stimulated with anti-CD3 MoAb for 4-96 h by using real-time qRT-PCR … The known mutations change single protein building blocks (amino acids) in β-actin. This is particularly so if housekeeping gene expression is the sole arbiter of the assay. Background: Several studies suggested that beta-actin, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and 18S rRNA are expressed constitutively and contribute to the fundamental reference actions essential for cell viability and maintenance. Beta Actin and GAPDH: The Importance of Loading Controls. Western blotting is an essential technique to probe protein expression in complex cell or tissue lysates. To accurately determine protein expression and interpret Western blot results, it is important to use loading controls.

GAPDH is a housekeeping gene and used as controls in both Western blot and qPCR. What is beta actin housekeeping gene? ; GAPDH is listed as a Top 20 housekeeping gene with the highest and most consistent average expression (She et al., 2009).Therefore GAPDH, together with beta actin and tubulin is one of the most commonly used loading controls. Housekeeping-type promoters, such as cytomegalovirus (CMV) enhancer/chikin β-actin (CAG), thymidine kinase (TK), Simian virus 40 (SV40), and ROSA26, drive general expression of reporter genes. Issue Date: November 2012 Beta-actin (or β-actin) is a cytoskeletal actin isoform, highly conserved and ubiquitously expressed in eukaryotic organisms, making it a commonly used "housekeeping gene" in many laboratory techniques. Housekeeping Gene Primer Sets - From $69.95. After 24 h of storage outdoors with an average temperature of 25.5 degrees C, beta-2 microglobulin (B2M), beta actin (ACTB) and phosphoglycerate kinase 1 (PGK1) were the most highly expressed transcripts in saliva, blood, vaginal secretions, and menstrual blood samples, and cyclophilin (PPIA), PGK1, and B2M were the most highly expressed transcripts in semen. Vice versa, beta-actin is more strongly expressed in the gizzard than GAPDH, but it is almost absent from cardiac muscle cells. Perform up to 1000 assays (based on 20 ul assay volume) for each housekeeping gene. Baraitser-Winter syndrome. Dev Genes Evol 222, 369–376 (2012).

Gene expression levels and stability of candidate reference genes for exosomes predicted with RNA-Seq data. Download citation. There are a variety of transgenic lines that express a reporter gene extensively in their organs, driven by ubiquitous promoters. Results show that despite being commonly used housekeeping genes neither GAPDH mRNA nor beta-actin mRNA is expressed in all cell types or tissues at high levels. Beta-actin is a major constituent of the contractile apparatus. Candidate housekeeping genes include AHSP, B2M, GAPDH, HBS1L, HPRT1 and SDHA. https://doi.org/10.1186/s12867-017-0089-9. I used both GAPDH and BETA ACTIN as my housekeeping genes (HK) but there is some small variation both between each of the HK genes and between samples. The expression levels of this protein do not vary drastically due to cellular treatment, which is another reason the protein makes a suitable control. Did you know? We are the first to report a novel panel of species-specific housekeeping genes (HKG) for CHO cells. I agree that it's helpful to use more than one internal control. Housekeeping protein levels are unfortunately not as stable we once thought. For w... According to the current study, the ubiquitous genes also previously called housekeeping genes such as PPIase, GAPDH, and beta-actin are expressed in all tissues with significant difference in their expression levels. The present study investigated hypothalamic expression of the housekeeping genes glyceraldehyde-3-phosphate dehydrogenase (GAPDH), beta-actin and 18s ribosomal RNA (18s rRNA) in offspring subjected to this pre- and postnatal dietary mismatch. Download citation. Published: 26 October 2012. Biochemical studies on transcription initiation of the housekeeping gene promoters have been difficult, partly due to the less-characterized promoter motifs and transcription initiation process. β-Actin, a cytoskeletal protein, and GAPDH, an enzyme of glycolysis, are the two most widely used housekeeping genes, 1 on the basis of rather anecdotal evidence of their consistency of Beta-actin is one of six different actin isoforms which have been identified in humans. beta-Actin and GAPDH housekeeping gene expression in asthmatic airways is variable and not suitable for normalising mRNA levels. Some literature would suggest that Both GAPDH and Beta actin are too variable across different tissue types. BMC Molecular Biol 18, 12 (2017). But this isn’t always so. @Jiaqi Shi In the reference you provided the investigators use actin for what appears to be whole cell lysates (Fig 5a). For their fractionation bl...
