BACKGROUND Kaposi sarcoma-associated herpesvirus (KSHV) encodes 12 pre-microRNAs that yield 25 mature microRNAs. We previously reported phylogenetic analysis of the microRNA-coding region of KSHV from Kaposi sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman disease (MCD) patients. We observed a high level of conservation for most sequences but also a divergent cluster of...
Small volume operation and rapid thermal cycling have been subjects of numerous reports in micro reactor chip development. Sensitivity aspects of the micro PCR reactor have not been studied in detail, however, despite the fact that detection of rare targets or trace genomic material from clinical and/or environmental samples has been a great challenge for microfluidic devices. In this study, a ...
Domestic cats share human living environments and genetic traits. They develop spontaneous feline mammary carcinoma (FMC) with similar histopathology to human breast cancer. HER2 and AKT phosphorylation was demonstrated in primary FMC by immunoblot analysis, indicating HER2 as a therapeutic target. FMC lines K12 and K248 expressing HER1, HER2, and HER3 were sensitive to receptor tyrosine kinase...
Using the single-stranded circular DNA of bacteriophage fd as template, double-stranded circular DNA has been prepared in vitro with either 5-hydroxymethylcytosine ([hmdC]DNA) or cytosine ([dC]DNA) in the product strand. Extracts prepared from Escherichia coli cells restrictive to T-even phage containing nonglucosylated DNA degrade [hmdC]DNA to acid-soluble material in uitro, but do not degrade...
PURPOSE The aim of this study is to further assess our previously reported keratin 12 (K12)-Leu132Pro specific siRNA in silencing the mutant allele in Meesmann's Epithelial Corneal Dystrophy (MECD) in experimental systems more akin to the in vivo situation through simultaneous expression of both wild-type and mutant alleles. METHODS Using KRT12 exogenous expression constructs transfected into...
The limbal region of the adult cornea contains stem cells which are ultimately responsible for regeneration of the corneal epithelium during wound repair. However, primarily-isolated murine corneal/limbal epithelial cells rapidly senesce on plastic in a serum-free low [Ca(2+)] medium, suggesting only transit amplifying cells are promoted. We developed a novel expansion method by seeding at a lo...
PURPOSE Adoptive T-cell therapy generally fails to induce meaningful anticancer responses in patients with solid tumors. Here, we present a novel strategy designed to selectively enhance the tumoricidal activity of T cells by targeted delivery of TNF-related apoptosis-inducing ligand (TRAIL) to the T-cell surface. EXPERIMENTAL DESIGN We constructed two recombinant fusion proteins, anti-CD3:TR...
این پژوهش، مطالعه ی اثر سورفکتانت آنیونی سدیم دو دسیل سولفات (sds) بر روی تعادلات تفکیک اسید آمینه ی تریپتوفان است. تعادلات اسیدی– بازی تریپتوفان برحسب ثابت های تفکیک ماکروسکوپی، میکروسکوپی و نسبت های تاتومری در محلول آبی و در حضور غلظت های مختلف sdsبررسی شد. به این منظور مقادیر ثابت های ماکروسکوپی (ka1 وka2)، ثابت تاتومری kz و مقادیر ثابت های میکروسکوپی (k11، k12،k21 و k22 ) تعیین شدند و مورد ...
برای شناسایی و آنالیز اینکه سویه هایe.coli عامل مولدعفونت ادراری دارای ویژگیهای مشترک با e.coli های مستقر در کولون هستند ضروری است ویژگیهاو شاخص های ویرولانس این دو گروه را مورد بررسی قرار دهیم.به طور کلی عفونت های خارج روده ای ناشی از سویه ها یی است که به طور گذرا در میکروبیوتای مدفوعی وجود دارند و دارای گروههای اختصاصی از ژنهای کد کننده فاکتورهای ویرولانس هستند. چنانچه این سویه هادر پرینئوم ک...
