Background: Electroporation is a valuable tool for small interfering RNA (siRNA) delivery into cells because it efficiently transforms a wide variety of cell types. Since electroporation condition for each cell type must be determined experimentally, this study presents an optimal electroporation strategy to reproducibly and efficiently transfect MDA-MB 468 human breast cancer cell with siRNA. ...

the p75 pan-neurotrophin receptor (p75ntr) plays a pivotal role in linking the immune system with the nervous system. p75ntr is required for the development of several characteristic features of allergic asthma. also p75ntr upregulated by reactive schwann cells after peripheral nerve injury. moreover p75ntr and rhoa play a critical role in the regulation of apoptosis. to determine whether the d...

Background: RNAi (RNA interference) is a new strategy in gene therapy and biotechnology which provides new promises in the treatment of different diseases such as cancer and viral diseases. CCND1 which is a key gene in cell cycle is amplified and over expressed in esophageal cancer. The objective of this study was production and siRNAs for CCND1, the key gene in cell cycle. Materials and Metho...

Background: The most important virulence factor which plays a central role in Candida albicans pathogenesis is the ability of this yeast to alternate between unicellular yeast and filamentous hyphal forms. Efg1 protein is thought to be the main positive regulating transcription factor, which is responsible for regulating hyphal-specific gene expression under most conditions. ALS3 is one of the ...

conclusions the development of delivery systems into bacteria with an efficacy compatible to that in human use could be a key for the potential utility of sirna for the prophylaxis and treatment of p. aeruginosa-induced hematogenous pulmonary infections in humans. results in quantitative rt–pcr,it was shown that the sirna significantly inhibited the expression of the flagella mrna. filc gene kn...

Gene silencing using RNAi (RNA interference), has recently been used as a successful laboratory technique in determining the function and control of gene expression and provides a wide range of applications in molecular biology and gene therapy. RNAi is a method of suppressing gene expression. In this direction, a single-stranded RNA molecule of about 21–23 nucleotides, called siRNA (small inte...

سرطان ریه شایع ترین علت مرگ و میر ناشی از سرطان در جهان می باشد و سالانه بیشتر از یک میلیون نفر به علت ابتلا به این بیماری جان خود را از دست می دهند. این سرطان به دو گروه اصلی به نام های سرطان ریه با سلول های غیر کوچک (NSCLC) و سرطان ریه با سلول های کوچک (SCLC) تقسیم می شود این دو گروه در خصوصیات بسیاری از جمله رفتارهای بیولوژیک، پاسخ به درمان و تغییرات ژنتیکی متفاوت هستند. مقاومت به درمانهای م...
