Towards Quantitative mRNA Analysis in Paraffin-Embedded Tissues Using Real-Time Reverse Transcriptase-Polymerase Chain Reaction

Real-time quantitative reverse transcriptase polymerase chain reaction.

The real-time quantitative reverse transcriptase polymerase chain reaction (RQ-PCR) has become the method of choice for the quantification of specific mRNAs. This method is fast, extremely sensitive, and accurate, requires only very small amounts of input RNA, and is relatively simple to perform. These characteristics have made it the method of choice for minimal residual disease monitoring suc...

Detection of Leishmania DNA in paraffin embedded specimens of chronic lupoid leishmaniasis using polymerase chain reaction

Background: Chronic lupoid leishmaniasis (CLL) is a chronicform of cutaneous leishmaniasis that is usually resistant to antileishmania agents and leishmania is not seen in the histologicsections. We used polymerase chain reaction (PCR) to detectleishmania DNA in CLL specimens.Method: This descriptive cross sectional study was done on20 paraffin embedded specimens of CLL cases referred to theder...

Pitfalls of quantitative real-time reverse-transcription polymerase chain reaction.

Polymerase chain reaction (PCR)-based assays can target either DNA (the genome) or RNA (the transcriptome). Targeting the genome generates robust data that are informative and, most importantly, generally applicable. This is because the information contained within the genome is context-independent; i.e., generally, every normal cell contains the same DNA sequence--the same mutations and polymo...

بررسی بیان ژن vegf در بیماران مبتلا به سرطان مری با استفاده از روش reverse transcriptase real- time polymerase chain reaction

سرطان مری با حدود 386000 مرگ و میر در سال ، ششمین عامل مرگ ناشی از سرطان در جهان است. vegf ، یکی از مهمترین تنظیم کننده های اختصاصی رگ زایی است.ژن vegf در انواع مختلف سرطان مری جهش یافته است. این ژن در مقابل ایجاد جهش در dna وکمبود اکسیژن در تومور فعال شده و تومور به واسطه بیان زیاد این ژن ، رگزایی را آغاز کرده و کمبود اکسیژن خود را از دریافت اکسیژن از خون دریافت کرده و در نهایت متاستاز تومور ر...
