Electrophoresis and spectrometric analyses of adaptation-related proteins in thermally stressed Chromobacterium violaceum. Repositório Alice
CORDEIRO, I. B.; CASTRO, D. P.; NOGUEIRA, P. P. O.; ANGELO, P. C. S.; NOGUEIRA, P. A.; GONÇALVES, J. F. C.; PEREIRA, A. M. R. F.; GARCIA, J. S.; SOUZA, G. H. M. F.; ARRUDA, M. A. Z.; EBERLIN, M. N.; ASTOLFI-FILHO, S.; ANDRADE, E. V.; LÓPEZ-LOZANO, J. L..
Chromobacterium violaceum is a Gram-negative proteobacteria found in water and soil; it is widely distributed in tropical and subtropical regions, such as the Amazon rainforest. We examined protein expression changes that occur in C. violaceum at different growth temperatures using electrophoresis and mass spectrometry.

Expression pattern of heat shock proteins during acute thermal stress in the Antarctic sea urchin, Sterechinus neumayeri RChHN
González,Karina; Gaitán-Espitia,Juan; Font,Alejandro; Cárdenas,César A.; González-Aravena,Marcelo.
BACKGROUND: Antarctic marine organisms have evolved a variety of physiological, life-history and molecular adaptations that allow them to cope with the extreme conditions in one of the coldest and most temperature-stable marine environments on Earth. The increase in temperature of the Southern Ocean, product of climate change, represents a great challenge for the survival of these organisms. It has been documented that some Antarctic marine invertebrates are not capable of generating a thermal stress response by means of an increase in the synthesis of heat shock proteins, which could be related with their low capacity for acclimatization. In order to understand the role of heat shock proteins as a compensatory response in Antarctic marine species to...

Identification and in silico analysis of the Citrus HSP70 molecular chaperone gene family Genet. Mol. Biol.
Fietto,Luciano G.; Costa,Maximiller D.L.; Cruz,Cosme D.; Souza,Alessandra A.; Machado,Marcos A.; Fontes,Elizabeth P.B..
The completion of the genome sequencing of the Arabidopsis thaliana model system provided a powerful molecular tool for comparative analysis of gene families present in the genome of economically relevant plant species. In this investigation, we used the sequences of the Arabidopsis Hsp70 gene family to identify and annotate the Citrus Hsp70 genes represented in the CitEST database. Based on sequence comparison analysis, we identified 18 clusters that were further divided into 5 subgroups encoding four mitochondrial mtHsp70s, three plastid csHsp70s, one ER luminal Hsp70 BiP, two HSP110/SSE-related proteins and eight cytosolic Hsp/Hsc70s. We also analyzed the expression profile by digital Northern of each Hsp70 transcript in different organs and in response...

Identification and in silico expression pattern analysis of Eucalyptus expressed sequencing tags (ESTs) encoding molecular chaperones Genet. Mol. Biol.
Cagliari,Thiago C.; Tiroli,Ana O.; Borges,Júlio C.; Ramos,Carlos H.I..
Expressed Sequence Tags (ESTs) sequencing provides reliable and useful information concerning gene expression patterns in the genomic context. Our group used bioinformatics to identify and annotate 5'EST-contigs belonging to the molecular chaperones within the Eucalyptus Genome Sequencing Project Consortium (FORESTs) database. We found that 1,959 5'EST-contigs, or approximately 1.6% of the total 5'EST-contigs, encoded chaperones, emphasizing their biological importance. About 55% of the chaperones that we found were Hsp70 chaperones and its co-chaperones, 18% were Hsp90 chaperones, 15% were Hsp60 and its co-chaperone, 8% were Hsp100 chaperones, and 4% were Small Hsps. We also investigated the digital expression profile of the chaperone genes to gain...
