Polypropylene microplastics (PP-MPs) are emerging environmental contaminants that have the potential to cause adverse effects on aquatic organisms. Reverse transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) is a valuable tool for assessing the gene expression profiles under PP-MPs stress. To obtain an accurate gene expression profile of tissue inflammation and apoptosis that reflects the molecular mechanisms underlying the impact of PP-MPs on Chinese sturgeon, identifying reliable reference genes is crucial for RT-qPCR analysis...

BACKGROUND: Quantitative real-time PCR (qPCR) is a highly reliable method for validating gene expression data in molecular studies due to its sensitivity, specificity, and efficiency. To ensure accurate qPCR results, it's essential to normalize the expression data using stable reference genes. METHODS: This study aimed to identify suitable reference genes for qPCR studies in goats by evaluating 18 candidate reference genes (ACTB, BACH1, B2M, GAPDH, HMBS, HPRT1, PGK1, PPIA, PPIB, RPLP0, RPL19, RPS9, RPS15, RPS28, SDHA, TBP, UXT, and YWHAZ) in 10 different caprine tissues (heart, intestine, kidney, liver, lung, muscle, rumen, skin, spleen, and testis)...

Quantitative PCR (qPCR) is a widely-used technique for quantifying the expression of target genes across various tissues, as well as under different pathological and physiological conditions. One of the challenges associated with this method is the need to identify optimal reference genes (RGs) that maintain consistent expression levels under diverse experimental settings, thereby ensuring accurate biological interpretation. In this study, we conducted a thorough analysis of 18 candidate RGs (ACTB, BACH1, B2M, GAPDH, HMBS, HPRT1, PGK1, PPIA, PPIB, RPLP0, RPL19, RPS9, RPS15, RPS28, SDHA, TBP, UXT, and YWHAZ) across 10 ovine tissues (muscle, skin, kidney, liver, intestine, rumen, lung, testis, heart, and spleen) obtained from five individual sheep...

Trauma triggers critical molecular and cellular signaling cascades that drive biological outcomes and recovery. Variations in the gene expression of common endogenous reference housekeeping genes (HKGs) used in data normalization differ between tissue types and pathological states. Systematically, we investigated the gene stability of nine HKGs ( Actb , B2m , Gapdh , Hprt1 , Pgk1 , Rplp0 , Rplp2 , Tbp , and Tfrc ) from tissues prone to remote organ dysfunction (lung, liver, kidney, and muscle) following extremity trauma...

Microplastics (MPs) and nanoplastics (NPs) have been deemed to be newly emerged contaminants interfering with various physiological processes closely related with gene expression alteration. Reverse transcriptase quantitative real-time polymerase chain reaction (RT-qPCR) serves as a powerful tool to assess gene expression, however highly dependent on a reliable reference gene. Therefore, it is necessary to identify stable reference genes for gene expression study under MP or NP stress. We constructed a mouse model postexposure to polypropylene microplastics (PP-MPs) to assess PP-MPs bioaccumulation in kidney, evaluate the kidney pathological changes, and then explore potential reference genes via RT-qPCR...

Brown adipose tissue (BAT) is mainly present in young mammals and is important for maintaining body temperature in neonatal mammals because of its ability to produce non-shivering thermogenesis. There is usually a large amount of BAT around the kidneys of newborn kids, but the BAT gradually "whiting" after birth. Screening and validating appropriate reference genes is a prerequisite for further studying the mechanism of goat brown adipose tissue "whiting" during the early stages. In this study, the expression stability of 17 candidate reference genes: 12 COPS8, SAP18, IGF2R, PARL, SNRNP200, ACTG1, CLTA, GANAB, GABARAP, PCBP2, CTSB , and CD151 ) selected based on previous transcriptome data as new candidate reference genes, 3 ( PFDN5, CTNNB1 , and EIF3M ) recommended in previous studies, and 2 traditional reference genes ( ACTB and GAPDH ) was evaluated...

Anguilla spp. is an important aquaculture species for which an increasing number of reference genes are being identified and applied. In this study, five housekeeping genes (RPL7, 18S, EF1A, ACTB, and GAPDH) were chosen to evaluate their reliability as reference genes for quantitative real-time PCR (qPCR) for the study of Anguilla anguilla. The expression of the selected genes in different eel tissues was determined by qPCR at different growth stages or upon challenge by Anguillid herpesvirus (AngHV), and the expression levels of these genes were then compared and evaluated with the geNorm and NormFinder algorithms...

BACKGROUND: Quantitative real time PCR (qPCR) is a powerful tool to evaluate mRNA expression level. However, reliable qPCR results require normalization with validated reference gene(s). In this study, we investigated stable reference genes in seven tissues according to four developmental stages in minipigs. Six candidate reference genes and one target gene (ACE2) were selected and qPCR was performed. BestKeeper, geNorm, NormFinder, and delta Ct method through the RefFinder web-based tool were used to evaluate the stability of candidate reference genes...

The genus Aeromonas is found worldwide in freshwater and marine environments and has been implicated in the etiology of human and animal diseases. In fish, among Aeromonas species, A. salmonicida causes massive mortality and great economic losses in marine and continental aquaculture species. Currently, several aspects of the clinical signs and pathogenesis of this Gram-negative bacterium have been described; however, determination of an appropriate reference gene is essential to normalize cellular mRNA data remain unknown...

The identification of the best reference gene is a critical step to evaluate the relative change in mRNA expression of a target gene by RT-qPCR. In this work, we evaluated nineteen genes of different functional classes using Real Time Human Reference Gene Panel (Roche Applied Sciences), to identify the internal housekeeping genes (HKGs) most suitable for gene expression normalization data in human cell lines. Normal cell lines CCD-19LU (lung fibroblast), HEK-293 (epithelial cell of embryonic kidney), WI-26 VA4 (lung fibroblast), and human cancer cells, BT-549 (breast cancer), Hs 578T (breast cancer), MACL-1 (breast cancer), HeLa (cervical carcinoma), U-87 MG (glioblastoma/astrocytoma), RKO-AS45-1 (colorectal carcinoma), and TOV-21G (ovarian adenocarcinoma) were cultivated according to manufacturer's protocol...

The majority of kidney diseases arise from the loss of podocytes and from morphological changes of their highly complex foot process architecture, which inevitably leads to a reduced kidney filtration and total loss of kidney function. It could have been shown that microRNAs (miRs) play a pivotal role in the pathogenesis of podocyte-associated kidney diseases. Due to their fully functioning pronephric kidney, larval zebrafish have become a popular vertebrate model, to study kidney diseases in vivo. Unfortunately, there is no consensus about a proper normalization strategy of RT-qPCR-based miRNA expression data in zebrafish...

Quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) has become a popular technique to assess gene expression. Suitable reference genes are normally identified first to ensure accurate normalization. The aim of the present study was to select the most stable genes in embryonic developmental stages, the early development of immune organs, and cells infected with Chinese rice-field eel rhabdovirus (CrERV) of the rice-field eel (Monopterus albus). Four reference genes, including those encoding 18S ribosomal RNA (18SrRNA), beta actin (β-actin), elongation factor 1 alpha (EF1ɑ), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were assessed using geNorm, NormFinder, BestKeeper, and RefFinder software...

The screening of reference genes for real-time quantitative PCR (qPCR) in forest musk deer (FMD) tissue is of great significance to the basic research on FMD. However, there are few reports on the stability analysis of FMD reference genes so far. In this study, We used qPCR to detect the expression levels of 11 reference gene candidates (18S rRNA, beta-actin [ACTB], glyceraldehyde-3-phosphate dehydrogenase [GAPDH], TATA box-binding protein [TBP], hypoxanthine phosphoribosyltransferase 1 [HPRT1], tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta polypeptide [YWHAZ], hydroxymethylbilane synthase [HMBS], eukaryotic translation elongation factor 1 alpha 1 [EEF1A1], succinate dehydrogenase complex flavoprotein subunit A [SDHA], peptidylprolyl isomerase B [PPIB], and ubiquitin C [UBC]) in heart, liver, spleen, lung and kidney of FMD...

BACKGROUND: Real-time PCR remains currently the gold standard method for gene expression studies. Identification of the best reference gene is a key point in performing high-quality qPCR, providing strong support for results, and performing as a source of bias when inappropriately chosen. Mesangial cells and podocytes, as essential cell lines to study diabetic kidney disease (DKD) physiopathology, demand accurate analysis of the reference genes used thus far to enhance the validity of gene expression studies, especially regarding high glucose (HG) and DKD treatments, with angiotensin II receptor blockers (e...

The accuracy of quantitative real time PCR (RTqPCR) can be attained only when a suitable reference gene is used. The gene expression for a particular gene may vary within different cells at different conditions. Hence, the suitability and stability of various potential reference genes have to be determined for expression studies. In this study, we have examined the potential of four different reference genes including β-Actin (ACTB), 18S ribosomal RNA (18S), glyceraldehyde-3P-dehydrogenase (GAPDH), and elongation factor 1 alpha (EF1AA ) in seven different tissues including gill, liver, kidney, spleen, heart, muscle and intestine of goldfish (Carassius auratus)...

Kidney-yang deficiency syndrome (KYDS) infected with the influenza virus is a suitable model to imitate a population at high-risk to influenza infection with a high rate of morbidity and mortality. However, the specific molecular mechanisms underlying this disease remain unclear. A stable reference gene is essential as an internal control for molecular biology research of this condition. Reverse-transcription-quantitative PCR (RT-qPCR) is considered an extremely sensitive technique used for absolute and relative quantification of target genes transcript levels...

In reverse transcription-quantitative polymerase chain reaction (RT-qPCR) studies, endogenous reference genes are routinely used to normalize the expression of target gene studies. In order to precisely evaluate the relative expression of genes in the cells of mice suffering from Kidney Yang Deficiency Syndrome (KYDS) in response to influenza A virus (IAV) H1N1 using RT-qPCR, it is crucial to identify reliable reference genes. In the present study, 15 candidate reference genes (Actb, β 2m, Gapdh, Gusb, Tuba, Grcc10, Eif4h, Rnf187, Nedd8, Ywhae, 18S rRNA, Rpl13, Ubc, Rpl32, and Ppia) were investigated in lung cells from KYDS mice infected with IAV H1N1...

Polycystic kidney disease is a complex clinical entity which comprises a group of genetic diseases that leads to renal cyst development. We evaluated the most suitable housekeeping genes for microRNA expression by RT-qPCR analyses of kidney tissues in Pkd1-deficient mouse models from a panel of five candidates genes (miR-20a, miR-25, miR-26a, miR-191 and U6) and 3 target genes (miR-17, miR-21 and let-7a) using samples from kidneys of cystic mice (Pkd1flox/flox :Nestincre , CY), non-cystic controls (Pkd1flox/flox , NC), Pkd1-haploinsufficient (Pkd1+/- , HT), wild-type controls (Pkd1+/+ , WT), severely cystic mice (Pkd1V/V , SC), wild-type controls (CO)...

Quantification real-time PCR (qRT-PCR) is a common method in analysis of gene expression, but the stable reference genes for the normalization analysis have not been appreciated before identifying expression pattern of genes in teleost fishes. In this study, we selected eight candidate reference genes (18S, Actin, EF-1α, 40S, B2M, TUBA, UBCE and GAPDH) basing on transcriptome analysis and the traditional housekeeping genes, and analyzed the stability of the reference genes in spleen, head kidney and head kidney leukocytes (HKL) after pathogen challenge in Schizothorax prenanti (S...

Quantitative real-time polymerase chain reaction is a widely used technique that relies on reference genes for the normalisation of gene expression. These reference genes are constitutively expressed and must remain stable across all samples and treatments. Stability of housekeeping genes may vary and must be optimised for a specific tissue, sample or cell line. Here we present a study screening for possible reference gene candidates, eef1a1 , rpl8 , sub1.L , clta , H4 and odc1 , in the Xenopus laevis (A6) kidney cell line...
