Rodent cells are notable for their inability to support normal assembly of HIV particles. In this report, we address possible causes for this defect by considering the hypothesis that mRNA-associated events occurring in the nucleus can regulate the activity of their encoded proteins in the cytoplasm. We show that altering the RNA nuclear export element used by HIV gag-pol mRNA from the Rev resp...

In this study we investigate the economic effects of carbon taxes on the Russian economy. The main findings of this study are the following: an introduction of carbon taxes compensated by an increase in lump-sum subsidies may weak the Russian economy through higher energy costs. Moreover, such an environmental tax reform could induce Dutch disease in Russia because of increases in the domestic ...

The efficient export of the Escherichia coli maltose-binding protein (MBP) is known to be SecB dependent, whereas ribose-binding protein (RBP) export is SecB independent. When the MBP and RBP signal peptides were exchanged precisely at the signal peptidase processing sites, the resultant RBP-MBP and MBP-RBP hybrid proteins both were efficiently exported in SecB+ cells. However, only MBP-RBP was...

Transduction of developmental and environmental cues into the nucleus to induce transcription and the export of RNAs to the cytoplasm through the nuclear pore complex (NPC) play pivotal roles in regulation of gene expression. The process of bulk export of mRNAs from nucleus to cytoplasm is highly conserved across eukaryotes. Assembly of export-competent mRNA ribonucleoprotein (mRNP) is coupled ...

In 2019, Malaysia's export scale was USD 237.8 billion, of which E&E products accounted for the largest share, 38%. This paper utilizes Gravity Model to analyse determinants industry exports. The results show that GDP and distance are in line with theory gravity model. Besides, exports based on H-O theory; can be increased by trading countries different factor endowments. appreciation ringg...

Export of mRNA from the nucleus to the cytoplasm is one of the essential steps for eukaryotic gene expression. In the fission yeast Schizosaccharomyces pombe, heat shock stress at 42 degrees C causes block of mRNA export from the nucleus. We now report that saline and ethanol stresses also inhibit nuclear mRNA export, resulting in accumulation of bulk poly (A)+ RNA, as well as a specific mRNA, ...

The study estimates the growth rates of frozen food, shrimp and total export, and instability of export earnings. The study evaluates the export marketing of frozen food; shrimp and fish by using time series aggregated data from the year of 1972-73 to 2005-06. The growth rates of frozen food were 44%, 11%, and 10% during post-war period (197273 to 1982-83), pre-trade liberalization (1983-84 to ...

Several studies of the yeast Saccharomyces cerevisiae support differential regulation of heat shock mRNA (hs mRNA) and non-hs mRNA nuclear export during stress. These include the finding that hs mRNA export at 42 degrees C is inhibited in the absence of the nucleoporinlike protein Rip1p (also called Nup42p) (C. A. Saavedra, C. M. Hammell, C. V. Heath, and C. N. Cole, Genes Dev. 11:2845-2856, 19...

Until now, identification of components of the flagellar protein export apparatus has been indirect. We have now identified these components directly by establishing whether mutants defective in putative export components could translocate export substrates across the cytoplasmic membrane into the periplasmic space. Hook-type proteins could be exported to the periplasm of rod mutants, indicatin...
