تغییرات اپی ژنتیکی بیان ژنها در کنار تغییرات ژنتیکی نقش مهمی را در ایجاد و پیشرفت تومور ایفا می کنند.پروتئینهای گروه پلی کمب از جمله مهار کننده های بیان ژنها هستند که سرنوشت سلول ها را در جریان تکامل و تمایز تعیین می کنند. این پروتئینها را براساس عملکرد و بیوشیمی به دودسته ی prc1 و prc2 تقسیم می کنند که هریک از چندین زیرواحد پروتئینی تشکیل شده اند. برهم خوردن فعالیت پروتئین های گروه پلی کمب در ...
هدف تحقیق: بررسی بیان ایزوفرم های ژن ppar ?در سلول های بنیادی جنینی موش طی تمایز عصبی می باشد. روش تحقیق: ابتدا توسط نرم افزار beacon designer پرایمر های مناسب برای real time pcr تهیه شد. در ادامه کارایی پرایمرهای طراحی شده تعیین شد. سلول های بنیادی جنینی موش د رحضور رتینوئیک اسید (ra) به سمت عصب تمایز داده شد و در سه مرحله سلول های بنیادی جنینی (esc) ، اجسام شبه جنینی تیمار شده با رتینوئیک...
We have previously described the development of a onetube SYBR Green real-time RT-PCR assay for the detection and quantitation of infectious salmon anemia virus (ISAV) in various biological samples. The twofold aim of the present study was to verify that the optimized SYBR Green real-time RT-PCR conditions could detect ISAV isolates of different geographic origins, and to analyze the growth pat...
Real-time reverse transcription polymerase chain reaction (RT-PCR) methods that monitor product accumulation were adapted for the validation of differentially expressed genes. We describe a real-time quantitative PCR assay that uses SYBR Green I dye-based detection and product melting curve analysis to validate differentially expressed genes identified by gene expression profiling technologies....
We have evaluated a real-time PCR procedure based on the LightCycler technology for rapid detection of herpes simplex virus (HSV) in genital lesions. Two sets of primers, corresponding to the thymidine kinase and DNA polymerase regions, were used for the amplification reactions in separate capillaries containing the SYBR Green I dye as detection signal. In 28 of 118 samples (24%), HSV was isola...
Cytomegalovirus (CMV) infection is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Therefore, preemptive ganciclovir therapy based on early detection of CMV reactivation is widely used to prevent CMV disease. Real-time polymerase chain reaction (PCR) has been widely used for monitoring CMV reactivation as well as the antigenemia assay that...
BACKGROUND It is often difficult for a physician to distinguish between viral and bacterial causes of respiratory infections and this may result in overuse of antibiotics. In many cases of community-acquired respiratory infections, clinicians treat patients empirically. The development of molecular methods for direct detection of viruses has been progressed recently. OBJECTIVES The objective ...
Background & Objective: Interferon belongs to a family of cytokines, which has the most important role in the innate immune response to virus infections. While producing recombinant interferon in biological host, some pieces of host nucleic acids remain in product. Because of limitations in previous techniques for detection of these impurities, the objective of this study is to use rapid ...
