Therefore, it is important to know how to reverse drug resistance. In this work, we investigated drug resistance reversal by StemRegenin-1(SR-1) in MCF-7/ADR cells and the mechanism by which it exerts its drug resistance effect. Methods: MTT test and protein blot were employed as the two main in vitro cell tests. The cells were treated with SR-1 and ADM to detect the changes in their proteomics, and then the effects of AhR downstream proteins, glucuronidase, and drug-resistant proteins were verified. The accumulation of ADM in the combined cells and its effect on the cell cycle were detected by flow cytometry. In vivo, a BALB/C mice xenograft test was conducted to observe the anti-tumor effect and side effects of the drug combination. Results: SR-1 combined with ADM inhibited cell proliferation and significantly decreased the expression of CYP1A1, UGT1A6, P-gP (ABCB1), and MRP1 (ABCC1). Furthermore, SR-1 caused apoptosis and cell cycle arrest. In vivo experiments showed that SR-1 significantly enhanced the antitumor effects of ADM and reduced the toxic effects of ADM. Conclusion: SR-1 inhibited AhR activity, decreased its downstream protein CYP1A1 and the expression of UGT1A6, P-gP, and MRP1 in MCF-7/ADR cells, and reversed drug resistance in MCF-7/ADR cells through AhR/ABC transports and AhR/UGTs pathways.","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141754007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Squalamine is a naturally occurring chemical substance with established antiviral and anticancer properties, and its profound impact on the α- Syn aggregation both in vivo and in vitro is well studied. Examining its interaction with lipid vesicles, which are known to encourage nucleation, can signify the mechanism of action of squalamine. The squalamine molecule is believed to displace α-Syn from the surfaces of the lipid vesicles, therefore preventing the initial steps in the process of aggregation. Additionally, the squalamine molecule reduces the harmful effects of α-Syn oligomers in human neuroblastoma cells by preventing them from interacting with lipid membranes. Objective: The aim of this study was to perform computational investigation of the conformational changes of membrane-bound α-Syn in the presence of squalamine inhibitor molecule objective: Computational investigation of the conformational changes of membrane-bound α-Synuclein in the presence of squalamine inhibitor molecule Method: Molecular Dynamics (MD) trajectory analysis was carried out to study the structural change of the α-Syn-squalamine conformers as a function of simulation time. The percentage of the secondary structural components of the α-Syn-squalamine complex was determined. Optimization of small molecule inhibitors was carried out using Density Functional Theory (DFT) analysis. Additionally, the values of electrophilicity (ω), nucleophilicity (N), Electron affinity (EA), and ionization potential (IP) were calculated. Results: The docking of the α-Syn-squalamine complex revealed the binding site and the best structure was selected based on the highest docking vina score (-5.8), and the contact residues were listed. From the conformational snapshots of the α-Syn-squalamine complex, it was evident that the α-Syn remained stable, maintaining its integrity throughout the simulation. The α-helical content was found to be retained from the secondary structural content analysis. The ω and N of the squalamine molecule were calculated to be -0.84 and 3.25, respectively. Conclusion: Our findings suggest that in the presence of a squalamine inhibitor molecule, α-Syn adopts a helical conformation that ensures stability and may indicate that the squalamine molecule causes gradual displacement of α-Syn across different regions within the lipid membrane.","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141588403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main challenge with therapy is the recurrence of antibiotic-resistant bacteria, and vaccination is still a problem. Therefore, the objective of the current study was to rationally design a multi-epitope vaccine using two immunogenic proteins found in H. pylori. Methods: Promising epitopes for the Leb-binding adhesin A (BabA) and vacuolating cytotoxin (VacA) proteins were characterized through an immunoinformatics approach. Epitope-rich fragments were selected based on high-binding affinities with HLA classes I and II to be specifically presented to B and T lymphocytes and to selectively elicit both humoral and cellular immune responses. Results: Six constructs were planned by fusing these fragments in different arrangements with the help of GPGPG linkers. The most stable three-dimensional structure was found in Construct 6 during molecular dynamics. To improve immunogenicity and stability, an adjuvant called human β- defensin 2 (hBD-2) was joined to the N-terminus of Construct 6. Following molecular docking, the final vaccine reacted appropriately with each toll-like receptor 2 (TLR-2), TLR3, and TLR-4. The final DNA sequence was optimized for expression in E. coli K12 and in silico cloned into a pET-28a(+) plasmid. As a result of the vaccination in silico, substantial responses were developed against H. pylori. Conclusion: According to the immune response simulation, activated B and T lymphocytes and memory cell production increased. Macrophages and dendritic cells proliferated continuously, and IFN-γ and Cytokines, such as IL-2 were raised.","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142217981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interaction between a crucial lipid modulatorPI3P and the C terminal lid domain of cytosolic PfHSP70-1, stabilizes the parasite digestive vacuole (DV) to facilitate hemoglobin trafficking and breakdown in turn impacting parasite survival. PfHSP70 homologs and PI3P are amply expressed together in various subcellular compartments of the parasite providing these with an opportunity to interact and affect biological processes. objective: The objectives of this study included identification of the PI3P binding pockets on PfHSP70s, understanding the binding affinity of each homolog for PI3P and identifying residues involved in different types of interactions. method: We have analyzed PI3P binding of all four PfHSP70s by using bioinformatics tools like sequence analysis, molecular docking and LigPlot+ analysis. result: Our results show that differently localized PfHSP70 homologs bind PI3P with variable affinity. The mitochondrial and ER localized PfHSP70s bind more strongly with PI3P than their cytosolic counterpart PfHSP70-1. The PI3P binding region on all PfHSP70 homologs lies at the interface of helices 1 and 3 of their substrate binding domain . Analysis of these results has also helped to pinpoint specific residues on PfHSP70s that may be engaged in these interactions. conclusion: PI3P preferentially binds to a particular pocket on PfHSP70 homologs. Different PfHSP70s bind to PI3P with variable binding affinity. Specific residues of PfHSP70 homologs involved in these interactions have been identified. other: The present study may therefore form the basis for designing interventions that hinder PfHSP70-PI3P interaction and influence parasite survival.","PeriodicalId":50601,"journal":{"name":"Current Proteomics","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140612995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chlorpromazine (CPZ) has been shown to inhibit the growth of oral cancer cells. However, the effects of CPZ on OSCC migration and its underlying molecular mechanisms remain unclear. Objective: We aimed to identify global protein changes and potential core proteins involved in CPZ-mediated inhibition of migration in SCC-15 cells using proteomics. Methods: We assessed the effect of CPZ on SCC-15 using CCK-8 assays and wound healing experiments. Next, we performed LC-MS-based proteomic analysis to identify protein alterations in SCC-15 cells treated with CPZ at different times. Differential expression proteins (DEPs) were identified and subjected to bioinformatics analysis using GO, KEGG, and PPI tools. Key candidate proteins were selected and validated using the TCGA-HNSCC database and molecular docking. Results: It was found that 20μm of CPZ had no effect on cell proliferation, but inhibited cell migration. A total of 4748 proteins were identified by Proteomics, among which 56 DEPs were identified, including 34 upregulated proteins and 22 downregulated proteins. Three proteins (RPF2, ACTB, and TGFBI) were identified as key candidate proteins associated with cell adhesion and migration in oral cancer cells. Conclusion: CPZ may affect the expression of RPF2, ACTB, and TGFBI proteins and change the extracellular matrix and cell adhesion function, thus inhibiting the migration of SCC-15 cells.

Methods: In this study, we focused on the expression of recombinant PurA from SEZ ATCC 35246. We evaluated the immunoreactivity of this recombinant protein using convalescent minipig sera. Additionally, we conducted experiments in mice to assess its immunogenic properties. Results: Our findings revealed that the recombinant PurA triggered a substantial antibody response in mice, resulting in an 80% protection rate against SEZ infection. Notably, mice immunized with PurA exhibited significantly reduced bacterial colonization in all organs compared to the PBS control group. Furthermore, the levels of IL-6, IL-8, IL-1β, and TNF-α in mouse serum were significantly elevated in the PurA-immunized group compared to the control group. Hyperimmune sera targeting PurA effectively eliminated SEZ in bactericidal tests. Remarkably, antibodies against PurA demonstrated a significant inhibitory effect on developing SEZ biofilm.
