Troglitazone is a thiazolidinedione insulin sensitizer drug for the treatment of type 2 non-insulin-dependent diabetes mellitus (NIDDM). Based on an increasing number of reports on troglitazone-associated liver toxicity, the cholestatic potential of troglitazone has been investigated. Rapid and dose-dependent increases in the plasma bile acid concentrations were observed in rats after a single ...

The DBP5 gene encodes a putative RNA helicase of unknown function in the yeast Saccharomyces cerevisiae. It is shown here that Dbp5p is an ATP-dependent RNA helicase required for polyadenylated [poly(A)+] RNA export. Surprisingly, Dbp5p is present predominantly, if not exclusively, in the cytoplasm, and is highly enriched around the nuclear envelope. This observation raises the possibility that...

Nucleo-cytoplasmic transport of proteins is mediated by nuclear export signals, identified in various proteins executing heterologous biological functions. However, the molecular mechanism underlying the orchestration of export is only poorly understood. Using microinjection of defined recombinant export substrates, we now demonstrate that leucine-rich nuclear export signals varied dramatically...

2015 Approximately 30% of all currently licensed, recombinantly expressed biotherapeutic products are produced in Escherichia coli, among which a significant proportion are exported to the periplasm by the general Secretory ‘Sec’ pathway. However, this pathway cannot handle many target proteins and the Tat pathway is emerging as a powerful alternative means of export. The Tat system exports ful...

in the present study, competitiveness of iranian pistachio exports and competitor countries in  the world market are studied. pistachio export advantage using indices of revealed comparative advantage (rca) approach and vector error correction model(vecm) based on  agricultural and non-petroleum export commodity basket were investigated separately. the results showed that iran has a comparative...

Gram-positive bacterial lipoproteins are a functionally diverse and important class of peripheral membrane proteins. Recent advances in molecular biology and the availability of whole genome sequence data have overturned many long-held assumptions about the export and processing of these proteins, most notably the recent discovery that not all lipoproteins are exported as unfolded substrates th...

U.S. nuclear export policy has undergone major transformations since 1945, and the most recent change, as expressed in the July 18, 2005, India-U.S. Joint Statement, represents an especially significant shift in policy. The document reverses more than a quarter century of U.S. declaratory policy, suggesting that the current U.S. administration regards nuclear proliferation to be both inevitable...
