Abstract
We carried out DNA microarray analysis after specific knockdown of EWS-Fli1 through transfection of synthetic siRNAs. EWS-Fli1 knockdown increased expression of genes such as DKK1 and p57 that are known to be repressed by EWS-Fli1 fusion protein. Among other potential EWS-Fli1 targets identified by...

Abstract
We characterize these opposing influences on gene expression in Caenorhabditis elegans olfactory neurons. Using transcriptional reporters that are expressed differentially in two olfactory neurons, AWC(ON) and AWC(OFF), we identify mutations that affect the long-term maintenance of appropriate chemo...

Abstract
We characterized a human H5N1 virus isolate (KAN-1) encoding a hemagglutinin (HA) with a K-to-E substitution at amino acid position 222 that was previously described to be selected in the lung of the infected patient. In mice, the growth of the HA(222E)-encoding virus was mainly confined to the lung...

Abstract
The Arabidopsis (Arabidopsis thaliana) fatty acid biosynthesis1 (fab1) mutant grows as well as wild type at 22 degrees C, but after transfer to 2 degrees C fab1 plants cannot maintain photosynthetic function and die after 5 to 7 weeks at 2 degrees C. A fab1 suppressor line, S7, was isolated in a scr...

Abstract
We have used cryoelectron tomography to investigate the morphotypes of this double mutant. Virions produced at the nonpermissive temperature do not assemble capsids, although Gag is processed normally; moreover, they are more variable in size than the wild type and have fewer glycoprotein spikes. At...

Abstract
We have developed an algorithm for the prediction of dual-targeting short interfering RNAs (siRNAs) in which both strands are deliberately designed to separately target different mRNA transcripts with complete complementarity. An advantage of this approach versus the use of two separate duplexes is...

Abstract
We engineered Escherichia coli cells with a translation system orthogonal to the E. coli tyrosyl-tRNA synthetase (TyrRS)-tRNA(Tyr) pair, to use E. coli TyrRS variants for non-natural amino acids in the cells without interfering with tyrosine incorporation. We showed that the E. coli TyrRS-tRNA(Tyr)...

Abstract
We investigated the basis for these other phenotypes and found that they are dependent on the toxic biosynthetic intermediate homoserine. Moreover, homoserine is also toxic for Candida albicans thr1Delta mutants. Since increasing levels of threonine, but not other amino acids, overcome the homoserin...

Abstract
We used the yeast Saccharomyces cerevisiae as a model. Our genetic screening has revealed that a defect in MPT5/HTR1/UTH4/PUF5 led to an increased sensitivity to BrdU, and that overexpression of VHT1 or SDT1 led to resistance to BrdU. The increased sensitivity to BrdU caused by a defect in MPT5 was...

Abstract
We recently showed that previous inactivation of pipX facilitates subsequent inactivation of the glnB gene. Here, we show that the three spontaneous pipX point mutations pipX-92delT, pipX160C>T and pipX194T>A, initially found in different glnB strains, are indeed suppressor mutations. When these mut...

NtAn2 shares high sequence homology with other known flavonoid-related MYB TFs and is mostly expressed in developing flowers. Constitutive ectopic expression of NtAn2 induces whole-plant anthocyanin production in toba...

We have isolated 115 independent extragenic suppressors of four ram mutations: tao3, hym1, kic1 and sog2. Over 50% of the suppressors affect a single residue in Cbk1p (S745F), which is close to the phosphorylation site in the hydrophobic motif. Our results show that the CBK1-S745F allele leads to a...

Thus sup35 mutations do not only decrease translation fidelity but also influenc...

However, only the E...
