BCL2-like 12 (BCL2L12 ) is a new member of the apoptosis-related BCL2 gene family, members of which are implicated in various malignancies. Nasopharyngeal carcinoma is a highly metastatic, malignant epithelial tumor, with a high prevalence in Southeast Asia and North Africa. The purpose of the current study was to quantify and investigate the expression levels of the BCL2L12 gene in nasopharyng...

BACKGROUND The reverse transcription (RT) of RNA to cDNA is a necessary first step for numerous research and molecular diagnostic applications. Although RT efficiency is known to be variable, little attention has been paid to the practical implications of that variability. METHODS We investigated the reproducibility of the RT step with commercial reverse transcriptases and RNA samples of vari...

Various biological and clinical applications require the quantification of the messenger RNA (mRNA) abundance of the biological materials under investigation. Reverse transcription-polymerase chain reaction (RT-PCR) is a popular technique for mRNA quantification. However, in these applications, multiple quantifications of mRNA are required from the same sample. Multiplex RT-PCR uses multiple pr...

cancer susceptibility genes from mRNA extracts with high sensitivity and specificity without RT-PCR amplification. Gene expression differences less than onefold were successfully detected. The lowest detectable amount of a specific gene was found to be 800 copies in 1.5 ng of mRNA. Integration of the sensor array into a fully automated microelectromechanical system, from tissue to nucleic acid ...

Kisspeptin is a hypothalamic peptide hormone that plays a pivotal role in pubertal onset and reproductive function. Previous studies have examined hypothalamic kisspeptin mRNA expression, either through in situ hybridisation or real-time RT-PCR, as a means quantifying kisspeptin gene expression. However, mRNA expression levels are not always reflected in levels of the translated protein. Kisspe...

The qRT-PCR has been widely accepted as the assay of choice for mRNA quantification. For conventional practice, housekeeping genes have been applied as internal reference for data normalization and analysis since the technology appeared. However, housekeeping genes vary under different conditions and environmental stimuli and no commonly accepted housekeeping gene references are available. Accu...

BACKGROUND n-ELAV (neuronal-Embryonic Lethal, Abnormal Vision)-like genes belong to a family codifying for onconeural RNA-binding proteins. Anti-Hu-antibodies (anti-Hu-Ab) are typically associated with paraneoplastic encephalomyelitis/sensory neuropathy (PEM/PSN), and low titres of anti-Hu-Ab, were found in newly diagnosed Small Cell Lung Cancer (SCLC). The aim of this study is to develop a sen...

Due to limitations of the currently used enzymatic assays, it is difficult to determine aromatase activity in testicular tissue of amphibians. Quantitative reverse transcription polymerase chain reaction (Q-RT PCR) is a sensitive and reliable technique to detect low amounts of mRNA for specific genes. This study was designed to develop and optimize a SYBR Green I-based Q-RT PCR method to quanti...

Chitinases hydrolyze the β-1-4 glycosidic bonds of chitin, a major structural component of fungi, crustaceans and insects. Although mammals do not produce chitin or its synthase, they express two active chitinases, chitotriosidase (Chit1) and acidic mammalian chitinase (AMCase). These mammalian chitinases have attracted considerable attention due to their increased expression in individuals wit...

pregabalin (prg) is a new antiepileptic drug and aceclofenac (ace) is a potent non-steroidal anti-inflammatory drug. these drugs in combination are used for treatment of partial seizures and neuropathic pains. a simple and precise assay method by rp-hplc was developed and validated for estimation of prg and ace in acenac-n tablet. analyses of commercial tablet, acenac-n were performed using jas...
