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...
Introduction & Objective: UTI is one of the most common bacterial infections and Ecoli is known as an important cause of UTIs. Since bacterial resistances of antibiotics are increasing, reliable methods of antimicrobial resistance detection are of paramount importance in treatment and management of UTIs. The objective of the present study is to compare and to evaluate the performance of disk ...
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 ...
We enumerate the nonisomorphic and the distinct one-factorizations of K12. We also describe the algorithm used to obtain the result, and the methods we used to verify these numbers.
A temperature-sensitive mutant K12 derived from a Chinese hamster fibroblast has been shown to overproduce three specific proteins of Mr 94,000, 78,000, and 58,000 when incubated at the nonpermissive temperature (40.5 degrees C). We previously identified these proteins as glucose-regulated proteins similar to those observed in chicken embryo fibroblasts when the cells are starved of glucose. In...
The cellobiose catabolic system of Escherichia coli K12 is being used to study the role of cryptic genes in evolution of new functions. Escherichia coli does not use beta-glucoside sugars; however, mutations in several loci can activate the cryptic bgl operon and permit growth on the beta-glucoside sugars arbutin and salicin. Such Bgl+ mutants do not use cellobiose, which is the most common bet...
Osteosarcoma (OS) is the most common primary malignancy of bone, and pulmonary metastatic disease accounts for nearly all mortality. However, little is known about the biochemical signaling alterations that drive the progression of metastatic disease. Two murine OS cell populations, K7M2 and K12, are clonally related but differ significantly in their metastatic phenotypes and therefore represen...
