Despite the advances in diagnosis and treatment of oral squamous cell carcinoma (OSCC), mortality and morbidity rates have not improved over the past decade. A major drawback in diagnosis and treatment of OSCC is the lack of knowledge relating to how genetic instability in oral cancer genomes affects oral carcinogenesis. Hence, the key aim of this study was to identify copy number alterations (...
Genomic abnormalities are the hallmark of cancers and may harbor potential candidate genes important for cancer development and progression. We performed array comparative genomic hybridization (array CGH) on 36 cases of primary lung adenocarcinoma (AD) using an array containing 2621 BAC or PAC clones spanning the genome at an average interval of 1 Mb. Array CGH identified the commonest aberrat...
High-Throughput Ultrasensitive Molecular Techniques for Quantifying Low-Density Malaria Parasitemias
The epidemiology of malaria in "low-transmission" areas has been underestimated. Molecular detection methods have revealed higher prevalences of malaria than conventional microscopy or rapid diagnostic tests, but these typically evaluate finger-prick capillary blood samples (∼5 μl) and therefore cannot detect parasite densities of <200/ml. Their use underestimates true parasite carriage rates. ...
Genomic structural variation is an important and abundant source of genetic and phenotypic variation. Here, we describe the first systematic and genome-wide analysis of copy number variations (CNVs) in modern domesticated cattle using array comparative genomic hybridization (array CGH), quantitative PCR (qPCR), and fluorescent in situ hybridization (FISH). The array CGH panel included 90 animal...
BACKGROUND Infantile hemangiomas are benign vascular tumors primarily found on the skin in 10% of the pediatric population. The etiology of this disease is largely unknown and while large scale genomic studies have examined the transcriptomes of infantile hemangioma tumors as a whole, no study to date has compared the global gene expression profiles of pure infantile hemangioma endothelial cell...
PURPOSE To determine the expression of inflammation- and pain-related genes at days 1 and 3 in the dorsal root ganglion (DRG) of rats with or without disc puncture, using real-time quantitative polymerase chain reaction (RT-qPCR) with the TaqMan low-density array (TLDA). METHODS 53 female Sprague-Dawley rats were used. The left facet joint between L4 and L5 was removed, and the DRG and interv...
The present study was designed to examine the expression and function of matrix metalloproteinase‑19 (MMP‑19), which is downregulated following respiratory syncytial virus (RSV) infection. The diverse expression levels of MMP were examined using a designed cDNA expression array. The expression and secretion of MMP‑19 was examined using reverse transcription‑quantitative polymerase chain reactio...
Variation in pre-analytical procedures can have effects on RNA expression in tissue. Standardization of the pre-analytical workflow is not always an option, therefore it is necessary to know which factors might be of influence and should be noted as meta data in tissuebank databases. Here we describe the discovery and potential use of a RT-qPCR fingerprint of genes sensitive to the ischemic per...
downs syndrome (ds) is one of the most common chromosomal abnormalities (1 in 700-1000 births) and one of the main causes of mental retardation. therefore, diagnosis and prevention of live-born children with ds is a principle priority for the iranian ministry of health. this study was performed to evaluate the application of real-time qpcr technique for rapid diagnosis of ds. about 15-20 millil...
Pneumococcal conjugate vaccine (PCV) immunization of children induces shifts in colonizing pneumococcal serotypes. This study evaluated the effect of infant vaccination with 7-valent PCV (PCV7) on vaccine serotype (VT) colonization and whether the increase in nonvaccine serotype (NVT) was due to either unmasking of previously low-density-colonizing serotypes or increase in acquisition of NVT. A...
