TranscriptomicsPhylogenetic, microbiological and glycoside hydrolase diversities within the extremely thermophilic, plant biomass-degrading genus Caldicellulosiruptor
Phylogenetic, microbiological and comparative genomic analysis was used to examine the diversity among members of the genus Caldicellulosiruptor with an eye towards the capacity of these extremely thermophilic bacteria for degrading the complex carbohydrate content of plant biomass. Seven species fr...

TranscriptomicsChromatin immunoprecipitation of REST/NRSF
ENCODE ChIP-chip study using 8 diverse human cell lines; 4 of neural origin (NB69, KELLY, SHSY-5Y, U373) and 4 of non-neural origin (HeLa, HepG2, HEK293 and K562) and anti-REST/NRSF antibody (Santa Cruz Biotech; sc-25398 aka H290) to asses REST-genome interactions across 1% of the human genome used...

TranscriptomicsTranscriptional Response of 0.1%YE-grown M. sedula cells to ferrous sulfate
(from abstract): Iron oxidation is a desirable trait of biomining microorganisms, although the mechanism is not well-understood in extreme thermoacidophiles. The complete genome sequence of the extremely thermoacidophilic archaeon Metallosphaera sedula DSM 5348 (2.2 Mb, ~2300 ORFs) provides insights...

TranscriptomicsM. sedula transcriptional response under heterotrophic, autotrophic, and mixotrophic growth conditions
To study mixotrophy, it is desirable to have an organism capable of growth in the presence and absence of both organic and inorganic carbon sources, as well as organic and inorganic energy sources. Metallosphaera sedula is an extremely thermoacidophilic archaeon which has been shown to grow in the p...

TranscriptomicsM. sedula transcriptional response to ferrous iron and RISC supplements
Abstract: The crenarchaeal order Sulfolobales collectively contains at least five major terminal oxidase complexes. Based on genome sequence information, all five complexes are found only in Metallosphaera sedula and Sulfolobus tokodaii, the two sequenced Sulfolobales capable of iron oxidization. Wh...

TranscriptomicsM. sedula transcriptional response under "strict" carbon-limited autotrophy compared to carbon "rich" autotrophy and heterotrophy
Metallosphaera sedula is an extremely thermoacidophilic archaeon that grows heterotrophically on peptides, and chemolithoautotrophically on hydrogen, sulfur, or reduced metals as energy sources. During autotrophic growth, carbon dioxide is incorporated into cellular carbon via the 3-hydroxypropionat...

TranscriptomicsUranium extremophily is an adaptive, rather than intrinsic, feature for extremely thermoacidophilic Metallosphaera species
Thermoacidophilic archaea are found in heavy metal-rich environments and, in some cases, these microorganisms are causative agents of metal mobilization through cellular processes related to their bioenergetics. Given the nature of their habitats, these microorganisms must deal with the potentially ...

TranscriptomicsMolecular Hydrogen Impact on Chalcopyrite Bioleaching by the Extremely Thermoacidophilic Archaeon Metallosphaera sedula
Hydrogen served as a competitive inorganic energy source, impacting the CuFeS2 bioleaching efficiency of the extremely thermoacidophilic archaeon Metallosphaera sedula. Open reading frames encoding key terminal oxidase and electron transport chain components were triggered by CuFeS2. Evidence of het...

TranscriptomicsTranscriptional analysis of the response of Caldicellulosiruptor saccharolyticus to different H2 partial pressures
Caldicellulosiruptor saccharolyticus is an extremely thermophilic, gram-positive anaerobe which ferments a broad range of substrates to mainly acetate, CO2, and hydrogen gas (H2). Its high hydrogen-producing capacity make this bacterium an attractive candidate for microbial biohydrogen production. H...

TranscriptomicsTranscription profiling by array of human cancer cell lines K562 and U937
Transcription profiling of two cancer cell lines: K562 and U937. It has recently been shown that nucleosome distribution, histone modifications and RNA polymerase II (Pol II) occupancy show preferential association with exons ("exon-intron marking"), linking chromatin structure and function to co- t...
