    Proteomics analysis provides novel biomarkers and therapeutic target candidates in the treatment of the Huang-Pu-Tong-Qiao formula in an AD rat model


    BIOCELL, Vol.47, No.6, pp. 1265-1277, 2023, DOI:10.32604/biocell.2023.028811

    Abstract Background: Huang-Pu-Tong-Qiao formula (HPTQ), a traditional Chinese herbal formula, has a variety of pharmacological effects. It has been used to treat Alzheimer’s disease (AD) for decades. This study aimed to screen differentially expressed proteins in the hippocampus of AD model rats treated with HPTQ. Proteomic studies of the effects of HPTQ on AD are key to understanding the therapeutic mechanisms of HPTQ and identifying potential therapeutic targets. Methods: We hence used the isobaric tags for relative and absolute quantification (ITRAQ) approach to investigate the differentially expressed proteins in the hippocampus of AD model rats before and after HPTQ administration and… More >

    Xue Lei1,#, Yong Zhao2,#, Rui Luo1, Mingda Yin1, Yanpeng Wen1, Zhiyan Wang1, Xuemei Hu1, Fenglan Huang1,3,4,5,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.5, pp. 1621-1632, 2023, DOI:10.32604/phyton.2023.027046

    Abstract Castor (Ricinus communis L.) is one of ten oil crops in the world and has complex inflorescence styles. Generally, castor has three inflorescence types: single female inflorescence (SiFF), standard female inflorescence (StFF) and bisexual inflorescence (BF). StFF is realized as a restorer line and as a maintainer line, which was applied to castor hybrid breeding. However, the developmental mechanism of the three inflorescences is not clear. Therefore, we used proteomic techniques to analyze different inflorescence styles. A total of 72 diferentially abundant protein species (DAPs) were detected. These DAPs are primarily involved in carbon and energy metabolism and carbon fixation… More >

    Oncologie, Vol.24, No.4, pp. 743-768, 2022, DOI:10.32604/oncologie.2022.025419

    Abstract Background: Aspirin (ASA) has been reported to have an antitumor effect but the role of ASA in the prevention and treatment of breast cancer (BC) is still controversial. This study aimed to identify clinical effectiveness of ASA in the treatment of BC and explore the antitumor target proteins of ASA that may be involved in overcoming tamoxifen resistance in estrogen receptor (ER)-positive BC cells. Materials and Methods: Randomized controlled trials (RCTs) of ASA in the treatment of BC were queried from the databases, including PubMed, Web of Science, Cochrane Library, WanFang, and Chinese National Knowledge Infrastructure.

    Global and Comparative Proteome Analysis of Nitrogen-Stress Responsive Proteins in the Root, Stem and Leaf of Brassica napus

    Liang Chai1,2, Cheng Cui1, Benchuan Zheng1, Jinfang Zhang1, Jun Jiang1, Haojie Li1,2,*, Liangcai Jiang1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.3, pp. 645-663, 2023, DOI:10.32604/phyton.2023.024717

    Abstract Nitrogen (N) is one of the basic nutrients and signals for plant development and deficiency of it would always limit the productions of crops in the field. Quantitative research on expression of N-stress responsive proteins on a proteome level remains elusive. In order to gain a deep insight into the proteins responding to nitrogen stress in rapeseed (Brassica napus L.), comparative proteomic analysis was performed to investigate changes of protein expression profiles from the root, stem and leaf under different N concentrations, respectively. More than 200 differential abundance proteins (DAPs) were detected and categorized into groups according to annotations, including… More >

    Proteomic Profiling and Protein-Protein Interaction Network Reveal the Molecular Mechanisms of Susceptibility to Drought Stress in Canola (Brassica napus L.)

    Reza Shokri-Gharelo1, Ali Bandehagh1,*, Mohammad Anwar Hossain2,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.7, pp. 1403-1417, 2022, DOI:10.32604/phyton.2022.020431

    Abstract Drought stress is one of the most important abiotic stresses that plants face frequently in nature. Under drought conditions, many morphological, physiological, and molecular aspects of plants are changed and as a result plants experience a remarkable reduction in growth, yield, and reproduction. To expand our understanding of the molecular basis of the plant response to drought stress, the proteomic profile and protein-protein network of canola (Brassica napus L.) were studied. The focus was to show molecular mechanisms related to canola susceptibility to drought stress. The experiment used a completely randomized design, implemented in a hydroponic system under greenhouse conditions.… More >

    Proteomics Analysis of Soybean Seedlings under Short-Term Water Deficit

    Xiyue Wang, Zihao Wu, Chao Yan, Chunmei Ma, Shoukun Dong*

    Phyton-International Journal of Experimental Botany, Vol.91, No.7, pp. 1381-1401, 2022, DOI:10.32604/phyton.2022.020251

    Abstract Soybeans are one of the most important grain crops worldwide. Water deficit, which seriously affects the yield and quality of soybeans, is the main abiotic stress factor in soybean production. As a follow-up study, the droughttolerant soybean variant Heinong 44 was analyzed via proteome analysis. Soybean was exposed to water deficit for 0, 8, and 24 h, and protein samples were extracted for detection of differentially expressed proteins. Protein sequencing of leaf tissues under water stress yielded a total of 549 differentially expressed proteins: 75 and 320 upregulated proteins as well as 70 and 84 downregulated proteins were obtained after… More >

    Abstract Chrysanthemum is one of the most important ornamental flowers in the world, and temperature has a significant influence on its field production. In the present study, differentially expressed proteins were investigated in the leaves of Dendranthema grandiflorum ‘Jinba’ under high temperature stress using label-free quantitative proteomics techniques. The expressed proteins were comparatively identified and analyzed. A total of 1,463 heat-related, differentially expressed proteins were successfully identified by Liquid Chromatography-tandem Mass Spectrometry (LC-MS/MS), and 1,463 heat-related, differentially expressed proteins were successfully identified by mass spectrometry after a high temperature treatment. Among these, 701 proteins were upregulated and 762 proteins were downregulated.… More >

    Quantitative Proteomics Analysis Identifies the Potential Mechanism Underlying Yellow-Green Leave Mutant in Wheat

    Wei Zheng, Zheng Shi, Mei Long, Yuncheng Liao*

    Phyton-International Journal of Experimental Botany, Vol.90, No.4, pp. 1147-1159, 2021, DOI:10.32604/phyton.2021.015916

    Abstract Enhancing photosynthesis efficiency is considered as one of the most crucial targets during wheat breeding. However, the molecular basis underlying high photosynthesis efficiency is not well understood up to now. In this study, we investigated the protein expression profile of wheat Jimai5265yg mutant, which is a yellow-green mutant with chlorophylls b deficiency but high photosynthesis efficiency. Though TMT-labeling quantitative proteomics analysis, a total of 72 differential expressed proteins (DEPs) were obtained between the mutant and wild type (WT). GO analysis found that they significantly enriched in thylakoid membrane, pigment binding, magnesium chelatase activity and response to light intensity. KEGG analysis… More >

    Comparative proteome analysis in hot pepper (Capsicum annuum L.) after space flight

    Xie LB1, X Wang1, M Peng2, Y Zhou1, LX Chen1, LX Liu3, YL Gao1, YH Guo1

    Phyton-International Journal of Experimental Botany, Vol.86, pp. 236-245, 2017, DOI:10.32604/phyton.2017.86.236

    Abstract Hot pepper (Capsicum annuum L.) is an important crop all over the world. To explore and identify differentially expressed proteins of hot pepper after space flight, three space-induced mutants (Y1, Y2 and Y3), which obtained new traits after space flight compared with their control lines (W1 and W2), were analyzed using comparative proteome analysis. In this study, leaf morphological characteristics of five kinds of hot pepper variations were evaluated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Results showed that obvious changes of cellular structure were seen in space induced mutants. Thirty nine out of the 255 differentially… More >
