Transformed Arabidopsis plants were used to study the effect of the cauliflower mosaic virus (CaMV) inclusion body protein on translation of dicistronic RNA. Reporter plants contain a dicistronic transcription unit with CaMV open reading frame VII (ORF VII) as the first and the [beta]-glucuronidase (GUS) reporter ORF as the second cistron. "Transactivator plants" contain CaMV ORF VI under the c...
A newly identified lethal form of hereditary sensory and autonomic neuropathy (HSAN), designated HSAN-VI, is caused by a homozygous mutation in the bullous pemphigoid antigen 1 (BPAG1)/dystonin gene (DST). The HSAN-VI mutation impacts all major neuronal BPAG1/dystonin protein isoforms: dystonin-a1, -a2 and -a3. Homozygous mutations in the murine Dst gene cause a severe sensory neuropathy termed...
Cellular microtubules composed of α-β-tubulin heterodimers that are essential for cell shape, division, and intracellular transport are valid targets for anticancer therapy. However, not all the conserved but differentially expressed members of the β-tubulin gene superfamily have been investigated for their role in these settings. In this study, we examined roles for the hematologic isoform β-t...
کروم شش ظرفیتی (VI) و یون سیانید (CN) بعنوان آلایندههای سمی متداول در پسابهای صنعتی به حساب میآیند. روشهای متعددی برای حذف آنها در نظر گرفته شده است. ولی علیرغم اینکه این آلایندهها همزمان در پساب وجود دارند این روشها برای حذف جداگانه آنها بکار رفته است. از اینرو هدف از این مطالعه، بررسی تاثیر حضور یون سیانید بر فرآیند حذف فتوکاتالیستی کروم (VI) توسط نانوذرات TiO2 تحت تابش نور UV است. بعد...
The expression of cauliflower mosaic virus proteins was examined in crown gall tissue transformed by integration of virus genome DNA into plant host chromosomes by Agrobacterium tumefaciens-mediated transfer. Galls upon plants of species that support infection by virus particles as well as upon non-host plants were analysed by immunoblotting using antisera specific to proteins encoded by viral ...
An Gram negative strain of S. maltophilia, indigenous to environments contaminated by Cr(VI) and identified by biochemical methods and 16S rRNA gene analysis, reduced chromate by 100%, 98-99% and 92% at concentrations in the 10-70, 80-300, and 500 mg/L range, respectively at pH 7 and temperature 37 °C. Increasing concentrations of Cr(VI) in the medium lowered the growth rate but could not be di...
The ability of chromatin to switch back and forth from open euchromatin to closed heterochromatin is vital for transcriptional regulation and genomic stability, but its dynamic structure is subject to disruption by exposure to environmental agents such as hexavalent chromium. Cr(VI) exposure disrupts chromatin remodeling mechanisms and causes chromosomal damage through formation of free radical...
The chromate efflux pump encoding gene chrASO was identified on the chromosome of Shewanella oneidensis MR1. Although chrASO is expressed without chromate, its expression level increases when Cr(VI) is added. When deleted, the resulting mutant ΔchrASO exhibits a chromate sensitive phenotype compared to that of the wild-type strain. Interestingly, heterologous expression of chrASO in E. coli con...
Two electrophoretic forms of erythrocytic carbonic anhydrase were found to be controlled by one autosomal locus with two codominant alleles, CA(f) and CA(8). The gene frequencies for the CA(f) and CA(8) alleles were found to be.15 and.85, respectively, in a sample of 53 mice from Middlesex County, New Jersey. The observed genotypic frequencies indicated that the population was in Hardy-Weinberg...
Attempt was made to study the factors that affect maximum yield of nonprotein nitrogen from various skeletal muscles. The results showed that sonification was the most, effective method out of the various extraction procedures used for the extraction of NPN, while the use of tungstic acid as protein precipitant was most suitable. The pH studies showed that pH 2 gave the optimal yield of NPN. Re...
