The interrelationships among the identified proteins were analyzed using Pearson's correlation analysis and pathway analysis. The PLS-DA models were able to distinguish each drug treatment group and the control group more importantly, the univariate differentially expressed protein spots were capable of being verified by the VIP of the models. The multivariate statistical test partial least squares-discriminant analysis (PLS-DA) was applied to build the models for screening out the variable important plot (VIP). This study used a comparative proteomics approach to identify the effects of the antipsychotic drugs, Chlorpromazine (CPZ), Clozapine (CLZ), and Quetiapine (QTP) on the synaptosomal protein of the cerebral cortex of Sprague-Dawley (SD) rats. This review provides a comprehensive analysis of current advances in the proteomics of SE, focusing on the presence and putative function of differentially expressed proteins involved in processes such as stress response, protein synthesis and processing, cell proliferation, signal transduction and energy metabolism, and their potential use as embryogenic markers. To better understand the mechanisms of somatic embryogenesis, comparative proteomic approaches have been used, and in recent years, hundreds of proteins have been identified in embryogenic and nonembryogenic cultures, in somatic and zygotic embryos, and during distinct stages of somatic embryogenesis in both angiosperms and gymnosperms. The transition of somatic cells into embryogenic ones is the most intriguing and the part of somatic embryogenesis least understood. The latter are morphologically similar to zygotic embryos and can regenerate whole plants. One of the most intriguing examples of this plasticity is somatic embryogenesis during which somatic cells dedifferentiate into cells that are capable to form embryos. Plants are sessile organisms and, as such, have evolved a remarkable developmental plasticity allowing them to cope with the adverse effects of numerous biotic and abiotic factors from the environment. quadrangularis degraded the peptidoglycan layer of bacteria by Cp was confirmed by transmission electron microscopic analysis.
quadrangularis was tested for antibacterial activity against Bacillus cereus and Bacillus megaterium which subsequently showed zone of inhibition of 21 and 20 mm respectively. Cp showed a potent antibacterial activity against pathogenic bacteria. The addition of metal ions such as Mg²⁺ and Ca²⁺ also exhibited relative protease activity. The Cp showed pH stability from 3 to 10 and retained more than 90% of its relative protease activity. The optimum pH and temperature for protease activity were around 6.0 and 50 ☌ respectively. The purified enzyme appeared as a single band on Native-PAGE. The molecular weight of the purified enzyme was estimated to be 39 kDa by SDS-PAGE. These results suggest that OsCP and OC-I may be involved in the process of suspension-cultured rice cells proliferation.Īn antibacterial Cp was extracted from the stem of Cissus quadrangularis and purified with a 5.39 fold increase in specific activity and 8.67% recovery. Recombinant protein of OC-I could inhibit the OsCP protease activity, also it could inhibit the weight increase of suspension-culture cell as well as extracellular protease activity. The fresh and dry weight growth rates of OsCP RNAi cell lines were lower than empty vector control. OsCP has been down regulated in vivo using RNAi transgenic lines. Among them, included a cysteine protease (OsCP) and a putative cysteine protease inhibitor (cystatin, OC-I).
Ten unique protein spots were isolated and identified by mass spectrometry. A comparative proteomic analysis was used to identify soluble extracellular proteins differentially expressed between 3 and 6 days in suspension-cultured cells.
The extract obtained from 3-d cultures was found to increase cells' fresh weight, while extracts from 6-d and 9-d cultures showed no effect on cells' growth. To identify extracellular proteins that regulate cell growth, the soluble proteins of extracellular matrix were extracted from suspension-cultured rice cells for different lengths of time. Extracellular matrix proteins play crucial roles in plant development, morphogenesis, cell division, and proliferation.
