Cancer; DmtDNA4977; In situ PCR; Kerns-Sayre syndrome deletion mutation; Mitochondria; Mitochondrial DNA; Real-time PCR

Levels of mtDNA4977 deletions (DmtDNA4977) have been found to be lower in tumors than in adjacent non-tumoral tissues. In 87 cancer patients, DmtDNA4977 was detected by multiplex polymerase chain reaction (PCR) amplification in 43 (49%) of the tumors and in 74 (85%) of the samples of non-tumoral tissues that ... more

CYP2D6*4; HLA-B27; Mutation; Real-time PCR

We analyzed distribution of HLA-B27 and CYP2D6*4 mutations in 249 patients from Tokat province in Turkey with symptoms of arthritis, sacroiliac, joint and back pain, using a LightCycler 480 II Real-Time PCR thermal cycler. The Genes-4U was applied for studying HLA-B27 mutation, and the Tib-Molbiol commercial kit was used to examine the CYP2D6*4 mutation. Among the 249 patients, 18.5% had ... more

Drought stress tolerance; Gene expression; Real-time PCR; Soybean; Transcription factor

To gain insight into stress-responsive gene regulation in soybean plants, we identified consensus sequences that could categorize the transcription factors MYBJ7, BZIP50, C2H2, and NAC2 as members of the gene families myb, bzip, c2h2, and nac, respectively. We also investigated the evolutionary relationship of these transcription factors and analyzed ... more

Broad-complex; Gene expression; In situ hybridization; RACE-PCR; Real-time PCR

Broad-Complex (BR-C) is an early ecdysone-responsive gene encoding a family of zinc-finger transcription factors that function during metamorphosis in insects. We identified two full-length cDNAs of BR-C Z6 in the giant tiger shrimp (Penaeus monodon). They were 2422 and 2060 bp in length, containing open reading frames of 1440 and 1443 bp, corresponding to ... more

Immunohistochemistry; Interleukin-8; Mammary cancer; Prognosis; Real-time PCR

The use of prognostic markers for mammary cancer is important for routine diagnosis and research. Interleukin-8 (IL-8) is a chemotactic cytokine, produced by several cell types in response to inflammation. The expression, regulation and function of IL-8 in dogs are little known. Recent studies have associated angiogenesis and inflammatory processes with tumor malignancy. We investigated a ... more

Immune response; Real-time PCR; Resistance to mastitis; Toll-like receptor 2 gene

Among the potential public health problems of animal production, infectious-contagious diseases stand out. Mastitis is among the main diseases affecting dairy cattle. One of the most promising options to reduce the problems caused by this disease, besides proper sanitary and management practices, is selective breeding of resistant animals. To shed light on the immune response mechanisms ... more

Detection; Quantification; Real-time PCR; Rice false smut; Ustilaginoidea virens

Rice false smut (RFS) is an important rice disease that is caused by the pathogen Ustilaginoidea virens. In this study, we developed a real-time polymerase chain reaction (PCR) assay to detect U. virens and to estimate the level of disease. The genomic DNAs of U. virens and rice were extracted together from the rice samples. Real-time PCR assays were performed ... more

Genomic DNA extraction; High-quality protocol; High-throughput protocol; Liquid nitrogen-free protocol; Phenol-chloroform-free protocol; Real-time PCR

The isolation of high-quality genomic DNA (gDNA) is a crucial technique in plant molecular biology. The quality of gDNA determines the reliability of real-time polymerase chain reaction (PCR) analysis. In this paper, we reported a high-quality gDNA extraction protocol optimized for real-time PCR in a variety of plant species. Performed in a 96-well block, our protocol provides high ... more

The current study was designed to evaluate lipid peroxidation (via malondialdehyde) levels, the superoxide dismutase (SOD) gene expression profile, and SOD enzyme activity in tomato plants (Lycopersicum esculentum L.) subjected to different time periods of cold stress (control, 2, 4, 6, 8, and 10 days). Results revealed that maximum lipid peroxidation occurred in ... more
