BACKGROUND Detection of tumor-associated genetic alterations in plasma of cancer patients has recently been suggested to be an accurate method for detecting early or recurrent cancer. METHODS We performed quantitative real-time PCR for MYC and GAPDH in tissue and plasma samples of 57 patients with gastric cancer and in plasma of 79 cancer-free individuals. We also performed two-color MYC fluo...
مقدمه: پیشرفت در ژنتیک مولکولی و عوامل تشخیص سرطان پستان در فهم بهتر زیست شناسی تغییر و تبدیل بافت سالم پستان به بافت سرطانی با خصوصیات تهاجمی و متاستاتیک کمک می کند. هدف این تحقیق به کارگیری روش قدرتمند real-time pcr نسبی مبتنی بر سایبرگرین جهت اندازه گیری نسبی بیان ژن گیرنده پروژسترون a در انسان می باشد. روش کار: 10 نمونه بافت طبیعی و 20 نمونه بافت سرطانی پستان (درجه2) قبل از درمان و بدون آلو...
with increased concentrations of GAPDH mRNA. Because circulating GAPDH mRNA in cancer patients was thought to originate in apoptotic cancer cells (2, 5), the increased concentrations of GAPDH mRNA detected may be caused by apoptosis in the placental residue in our case. We conclude that real-time quantitative RT-PCR is a sensitive method to monitor changing mRNA concentrations resulting from ap...
Quantitative real time RT-PCR has been described as the most sensitive method for the detection of low abundance mRNA. To date, no reference genes have been screened in the half-smooth tongue sole (Cynoglossus semilaevis). The aim of this study was to select the most stable genes for quantitative real-time RT-PCR. Eight housekeeping genes (18S, TUBA, B2M, ACTB, EF1A, GAPDH, RPL17 and UBCE) were...
Real time-qPCR is the most reliable method for evaluation of mRNA expression levels. However, to obtain accurate results, selection of suitable reference genes is necessary for normalizing the real-time qPCR data. The aim of this research was to validate the expression stability of three potential reference genes (ACTB, GAPDH and UXT) in milk somatic cells of Holstein dairy cattle under differe...
Quantitative gene expression data are often normalized to the expression levels of control or so-called "housekeeping" genes. An inherent assumption in the use of housekeeping genes is that expression of the genes remains constant in the cells or tissues under investigation. Although exceptions to this assumption are well documented, housekeeping genes are of value in fully characterized system...
Background: Breast cancer is one of the most prevalent malignancies among women in various countries. HER2 overexpression, which is due to different reasons, occurs in 20-30% of breast cancers. HER2 gene encodes an 185kDa transmembrane glycoprotein with 1255 amino acids. This active product triggers downstream intracellular signaling pathways inducing cell proliferation and cell survival. These...
objective: understanding gene expression variations by using rna transcript analysis methods during hepatic viral protein interactions with the ifn pathway in hepatic cell lines has recently gained importance. one of the most powerful techniques in gene expression quantification is quantitative real-time rt-pcr. reference genes used as normalizer in this method may be affected across various ex...

گیرنده فاکتور رشد اپیدرمی her-2 به طور مکرر در سرطان پستان و چندین تومور جامد دیگر دچار افزایش بیان می گردد. افزایش بیان ژن her-2 در 10 تا 34% از بیماران سرطان پستان مشاهده شده و بر روی پیشرفت، درمان و تشخیص بیماری موثر است. در نتیجه بررسی صحیح بیان ژن her-2 در سلول های توموری در اداره بیماری و انتخاب صحیح بیمارانی که قادر به درمان با داروهای معمول مانند تراستوزوماب می باشند مهم و ضرورری است. ب...
