Ssa1/2p, members of one of the yeast cytosolic hsp70 subfamilies, have been implicated in the translocation of secretory proteins into the lumen of the ER. The involvement of these hsp70s in translocation was tested directly by examining the effect of immunodepleting Ssa1/2p from yeast cytosol and subsequently testing the cytosol for its ability to support co- and post-translational translocati...

The Saccharomyces cerevisiae Tid1 protein is important for the recombinational repair of double-stranded DNA breaks during meiosis. Tid1 is a member of Swi2/Snf2 family of chromatin remodeling proteins and shares homology with Rad54. Members of this family hydrolyze ATP and promote 1) chromatin remodeling, 2) DNA topology alterations, and 3) displacement of proteins from DNA. All of these activ...

introduction: bacterial translocation is defined as the passage of bacteria from intestinal tract to the extraintestinal organs such as the peritoneum and blood circulation. the aim of this study is to examine bacterial translocation (regarding type of bacteria and effect of time of obstruction on bacterial translocation) from intestinal lumen to the peritoneum and viscera in acute, simple mech...

Background: Acute Myeloid Leukemia (AML) with translocation (3,3) is a form of AML that may present de novo or may arise from a previous myelodysplastic syndrome. It is often associated with normal or elevated peripheral blood platelet count and increased bone marrow megakaryocytes with associated multi lineage dysplasia. A subset of patients present with hepatosplenomegaly while a few cases h...

Ecological risk assessment of mercury contaminant has a means to analyze the ecological aspect ecosystem using potential impact pollution in soil, water and organism. The coastal area can be shown by mangrove zonation, clustering interpolation accumulation. This research aims (including bioaccumulation translocation) indicators species distribution, clustering, zonation results showed that Sega...

Members of the fibroblast growth factor family bind to one or more of the four closely related membrane-spanning FGF receptors. In addition to signaling through the receptors, exogenous FGF-1 and FGF-2 are endocytosed and translocated to the cytosol and nucleus where they stimulate RNA and DNA synthesis. Here we have studied the ability of the four FGF receptors to facilitate translocation of e...

Among 17786 karyotyres performed in our center,during 18 years (1357-1375),1300(7.3%) cases of chromosome 21 aberration,including 1284(98.77%) of Down syndrome have been detected.1191 of cases (92.76%) born free trisomy 21:61 cases (4.75%) revealed translocation and 32 cases (2.4%) showed mosaic pattern.among the pateints,59 had robertsonian translocation,2 had translocation between chromosome ...

Triploidy is a lethal chromosomal abnormality. Foetuses with triploid condition have a tendency to die in early conception and very few survive to term. In this study, we report the prenatal diagnosis of fetal triploidy with unexpected chromosomal translocation. A 27 years old women was referred to our clinical cytogenetic department due to history of previous conceptus with intrauterine growth...

Ricin translocation was demonstrated (using both fluorescence- and radiolabel-based assays) across the membrane of endosomes purified from mouse lymphocytes. Selectivity of the process was shown by the absence of translocation activity of transferrin and horseradish peroxidase used as membrane-bound and fluid-phase endosome labels, respectively. Endocytosed 125I-ricin translocation was found to...
