بررسی بیان ژن P53 در بیماران مبتلا به سرطان مری با استفاده از روش Reverse transcriptase real time polymerase chain reaction

چکیده سابقه و هدف: سرطان مری، ششمین عامل مرگ ناشی از سرطان در جهان است. شیوع سرطان مری در ایران بسیار بالاست. P53 یکی از شناخته‌شده‌ترین ژن‌های بازدارنده‌ی تومور است که در برابر آسیب‌های وارده به DNA فعال می‌شود و هدف مهمی برای تحقیقات شناخته می‌شود. به دلیل اینکه تاکنون هیچ تحقیق و پژوهشی در مورد ژن P53 در بیماران مبتلا به سرطان مری با تکنیک Real-time PCR در ایران انجام نگرفته است، ضرورت انجام...

Application of Real-time Polymerase Chain Reaction (RT-PCR)

The real-time polymerase chain reaction (RT-PCR), also called quantitative real-time polymerase chain reaction (QRT-PCR) or kinetic polymerase chain reaction (kPCR), is a technique used to simultaneously quantify and amplify a DNA molecule. It is used to determine whether a specific DNA sequence is present in the sample; and if it is present, the number of copies in the sample. It is the real-t...

Development and Evaluation of Real-Time Reverse Transcription Polymerase Chain Reaction Test for Quantitative and Qualitative Recognition of H5 Subtype of Avian Influenza Viruses

Avian influenza viruses (AIV) affect a wide range of birds and mammals, cause severe economic damage to the poultry industry, and pose a serious threat to humans. Highly pathogenic avian influenza viruses (HPAI) H5N1 were first identified in Southeast Asia in 1996 and spread to four continents over the following years. The viruses have caused high mortality in chickens and various bird species ...

Quantitative Real-time Polymerase Chain Reaction (qRT-PCR). Fatemeh Mehrpooyan*

A novel method for real time quantitative RT-PCR.

A novel approach to quantitative reverse transcriptase polymerase chain reaction (QC RT-PCR) using real time detection and the 5' nuclease assay has been developed. Cystic fibrosis transmembrane transductance regulator (CFTR) target mRNA is reverse transcribed, amplified, detected, and quantitated in real time. A fluorogenic probe was designed to detect the CFTR amplicon. Relative increase in 6...

Measurement of cytochrome P450 gene induction in human hepatocytes using quantitative real-time reverse transcriptase-polymerase chain reaction.

Drug-induced changes in expression of cytochrome (CYP) P450 genes are a key cause of drug-drug interactions. Consequently, preclinical prediction of these changes by novel compounds is an integral component of drug development. To date, in vitro models of CYP induction have used mRNA measurement, immunodetection, and substrate metabolism as reporters. Here, we describe the application of quanti...
