زمینه:طی سال‌های اخیر، بروز و گسترش مقاومت داروئی در مایکوباکتریوم توبرکلوزیس، باکتری مولد سل، این بیماری را در اولویت‌های سازمان بهداشت جهانی هم‌ردیف بیماری‌هایی مانند ایدز و هپاتیت قرار داده است. بررسی دقیق ژنوتیپ سویه‌های کلینیکی مقاوم و حساس برای غلبه بر مقاومت دارویی ایجاد شده ضرورت دارد. از میان سیستم‌های متعدد ترمیم تنها تعداد محدودی ژن کد کننده آنزیم‌های ترمیم DNAدر مایکوباکتریوم توبرکل...

Facilitative UT-A urea transporters play a central role in the urinary concentrating mechanism. There are three major UT-A isoforms found in the mouse kidney: mUT-A1, mUT-A2, and mUT-A3. The major aim of this study was to identify the location and function of mUT-A3. UT-A proteins were investigated using three novel mouse UT-A-targeted antibodies: ML446, MQ2, and ML194. ML446 detected mUT-A1 an...
BACKGROUND Dog breeds with the ABCB1-1Δ mutation have substantially truncated nonfunctional P-glycoprotein. Dogs homozygous for this mutation (mut/mut) are susceptible to the toxic adverse effects of ivermectin, loperamide, and vincristine. Anecdotal reports suggested ABCB1 mut/mut dogs showed increased depth and duration of acepromazine sedation. HYPOTHESIS/OBJECTIVES That ABCB1 mut/mut dogs...
Argonaute-associated siRNAs and Piwi-associated piRNAs have overlapping roles in silencing mobile genetic elements in animals. In Caenorhabditis elegans, mutator (mut) class genes mediate siRNA-guided repression of transposons as well as exogenous RNAi, but their roles in endogenous RNA silencing pathways are not well-understood. To characterize the endogenous small RNAs dependent on mut class ...
Mutation in Cu/Zn-superoxide dismutase (SOD1) is a cause of familial amyotrophic lateral sclerosis (ALS). Mutant SOD1 protein (SOD1(mut)) induces motor neuron death, although the molecular mechanism of SOD1(mut)-induced cell death remains controversial. Here we show that SOD1(mut) specifically interacted with Derlin-1, a component of endoplasmic reticulum (ER)-associated degradation (ERAD) mach...
Chicken anemia virus (CAV) is a significant immunosuppressive pathogen of chickens, but relatively little is known about the effect of specific mutations on its virulence. In order to study the virulence of CAV, an infection model was developed in embryos. Significant growth depression, measured as a reduction in mean body weight, was found for wild-type CAV infection. Infection with wild-type ...
Isolated methylmalonic acidemia (MMA), caused by deficiency of the mitochondrial enzyme methylmalonyl-CoA mutase (MUT), is often complicated by end stage renal disease that is resistant to conventional therapies, including liver transplantation. To establish a viable model of MMA renal disease, Mut was expressed in the liver of Mut(-/-) mice as a stable transgene under the control of an albumin...
More than 2,000 C. elegans genes are targeted for RNA silencing by the mutator complex, a specialized small interfering RNA (siRNA) amplification module which is nucleated by the Q/N-rich protein MUT-16. The mutator complex localizes to Mutator foci adjacent to P granules at the nuclear periphery in germ cells. Here, we show that the DEAD box RNA helicase smut-1 functions redundantly in the mut...
In a previous study, tomato race 3 (T3) strains of Xanthomonas perforans became predominant in fields containing both X. euvesicatoria and X. perforans races T1 and T3, respectively. This apparent ability to take over fields led to the discovery that there are three bacteriocin-like compounds associated with T3 strains. T3 strain 91-118 produces at least three different bacteriocin-like compoun...
