objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
بیان بیش از حد پروتئین گیرنده فاکتور شماره2 رشد اپیدرمی انسان (her2) در درصد قابل توجهی از موارد سرطان پستان انسان رخ می دهد. آنتی بادیهای منو کلونال her2 بعنوان عوامل تشخیصی و درمانی به شکل گسترده ای استفاده می شود. با این وجود شناسایی شناساگر مولکولی با خصوصیات تشخیصی و درمانی برتر از اهمیت زیادی برخوردار است. آپتامرها از این جهت امید بخش می باشند. در مطالعه حاضر روش پنینگ سلولی (cell selex )...
background: nowadays, highly specific aptamers generated by cell selex technology (systematic evolution of ligands by exponential enrichment) are being applied for early detection of cancer cells. prostate specific membrane antigen (psma), over expressed in prostate cancer, is a highly specific marker and therefore can be used for diagnosis of the prostate cancer cells. the aim of the present s...
SELEX (systematic evolution of ligands by exponential enrichment) is a process involving the progressive isolation of high selective ssDNA/RNA from a combinatorial single-stranded oligonucleotide library through repeated rounds of binding, partitioning and amplification. SELEX-derived single-stranded DNA/RNA molecules, called aptamers, are selected against a wide range of targets, including pur...
Aptamers are single-stranded oligonucleotides of DNA or RNA that bind to target molecules with high affinity and specificity. Typically, aptamers are generated by an iterative selection process, called systematic evolution of ligands by exponential enrichment (SELEX). Recent advancements in SELEX technology have extended aptamer selection from comparatively simple mixtures of purified proteins ...
Systematic evolution of ligands by exponential enrichment (SELEX) is an established procedure for developing short single-stranded nucleic acid ligands called aptamers against a target of choice. This approach has also been used for developing aptamers specific to whole cells named Cell-SELEX. Aptamers selected by Cell-SELEX have the potential to act as cell specific therapeutics, cell specific...
Aptamers, single stranded DNA or RNA molecules, generated by a method called SELEX (systematic evolution of ligands by exponential enrichment) have been widely used in various biomedical applications. The newly developed Cell-SELEX (cell based-SELEX) targeting whole living cells has raised great expectations for cancer biology, -therapy and regenerative medicine. Combining nanobiotechnology wit...
Aptamers are high affinity single-stranded DNA/RNA molecules, produced by a combinatorial procedure named SELEX (Systematic Evolution of Ligands by Exponential enrichment), that are emerging as promising diagnostic and therapeutic tools. Among selection strategies, procedures using living cells as complex targets (referred as "cell-SELEX") have been developed as an effective mean to generate ap...
سرطان پروستات یکی از رایج ترین بدخیمی های مردان و آنتی ژن غشایی اختصاصی سلول های سرطانی پروستات(psma) که بیانش در این سرطان افزایش میابد، یک مارکر مولکولی بسیار اختصاصی برای تشخیص و درمان سرطان پروستات است. به سبب ویژگی های منحصر به فرد آپتامر ها، در چند دهه ی اخیر استفاده از آپتامر ها در مطالعات سرطانی افزایش یافته است. آپتامر ها مولکول های rna یاdna تک رشته ای هستند که طی فرایند تکاملی ایجاد ...
