Proteomic analysis of differentially expressed proteins induced by salicylic acid in suspension-cultured ginseng cells.

Saudi journal of biological sciences

Sun J, Fu J, Zhou R.
PMID: 24600313
Saudi J Biol Sci. 2014 Apr;21(2):185-90. doi: 10.1016/j.sjbs.2013.09.011. Epub 2013 Oct 09.

In this study, optimized 2-DE sample preparation methodologies were established for suspension-cultured ginseng cells. Three commonly used protein extraction methods (Trichloroacetic acid-acetone, urea/thiourea and phenol extraction method) were evaluated for proteomic analysis of suspension cultures of ginseng. A comparative...

Localization of a multifunctional chaperonin (GroEL protein) in nitrogen-fixing Anabaena PCC 7120 : Presence in vegetative cells and heterocysts.

Jāger KM, Bergman B.
PMID: 24193540
Planta. 1991 Dec;183(1):120-5. doi: 10.1007/BF00197575.

The occurrence and distribution of a multifunctional chaperonin-60 (cpn60), the GroEL protein, was demonstrated in the cyanobacterium Anabaena PCC 7120 by using a rabbit anti-GroEL (Escherichia coli) antibody. Western-blot analysis showed a distinct cross-reaction with a protein of approx....

Following publication of this article, the authors realized that there were 1) errors made in the author affiliations and that 2) a typo in a grant number needed to be corrected. The corrected author affiliations and grant numbers are...

Comparative Proteome Analysis of Wheat Flag Leaves and Developing Grains Under Water Deficit.

Frontiers in plant science

Deng X, Liu Y, Xu X, Liu D, Zhu G, Yan X, Wang Z, Yan Y.
PMID: 29692790
Front Plant Sci. 2018 Apr 10;9:425. doi: 10.3389/fpls.2018.00425. eCollection 2018.

In this study, we performed the first comparative proteomic analysis of wheat flag leaves and developing grains in response to drought stress. Drought stress caused a significant decrease in several important physiological and biochemical parameters and grain yield traits,...

Toward a better understanding of preeclampsia: Comparative proteomic analysis of preeclamptic placentas.

Proteomics. Clinical applications

Kim YN, Kim HK, Warda M, Kim N, Park WS, Prince Adel B, Jeong DH, Lee DS, Kim KT, Han J.
PMID: 21136660
Proteomics Clin Appl. 2007 Dec;1(12):1625-36. doi: 10.1002/prca.200700034. Epub 2007 Nov 16.

Preeclampsia (PE), a pregnancy-specific syndrome of hypertension, proteinuria, and other systemic disturbances, is a state of widespread endothelial dysfunction secondary to defective placentation. Morphologically, the current data displayed degenerative and apoptotic changes in the mitochondria and villous trophoblasts of...

Detection of blueberry stunt phytoplasma in Eastern Canada using cpn60-based molecular diagnostic assays.

Scientific reports

Hammond C, Pérez-López E, Town J, Vincent C, Moreau D, Dumonceaux T.
PMID: 34764366
Sci Rep. 2021 Nov 11;11(1):22118. doi: 10.1038/s41598-021-01439-4.

Blueberry stunt phytoplasma (BBSP; 'Candidatus Phytoplasma asteris') is an insect-vectored plant pathogen that causes severe yield losses in blueberry (Vaccinium corymbosum), which is the most valuable fruit crop in Canada. Rapid, field-based diagnostic assays are desirable tools for the...

Characterization of Thylakoid-Derived Lipid-Protein Particles Bearing the Large Subunit of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase.

Plant physiology

Smith MD, Ghosh S, Dumbroff EB, Thompson JE.
PMID: 12223858
Plant Physiol. 1997 Nov;115(3):1073-1082. doi: 10.1104/pp.115.3.1073.

Lipid-protein particles bearing the 55-kD ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) (EC 4.1.1.39) large subunit (RLSU) and no detectable corresponding Rubisco small subunit (RSSU) were isolated from the stroma of intact chloroplasts by flotation centrifugation. Stromal RLSU-bearing particles appear to originate from...

Chaperonins are cell-signalling proteins: the unfolding biology of molecular chaperones.

Expert reviews in molecular medicine

Ranford JC, Coates AR, Henderson B.
PMID: 14585136
Expert Rev Mol Med. 2000 Sep 15;2(8):1-17. doi: 10.1017/S1462399400002015.

The chaperonins are a subgroup of oligomeric molecular chaperones; the best-studied examples are chaperonin 60 (GroEL) and chaperonin 10 (GroES), both from the bacterium Escherichia coli. At the end of the 20th century, the paradigm of chaperonins as protein...

ATP induces large quaternary rearrangements in a cage-like chaperonin structure.

BACKGROUND: The chaperonins, a family of molecular chaperones, are large oligomeric proteins that bind nonnative intermediates of protein folding. They couple the release and correct folding of their ligands to the binding and hydrolysis of ATP. Chaperonin 60 (cpn60)...
