Antimicrobial peptides possess the ability to directly eliminate pathogens and cancer cells, generally without the development of resistance. Among these peptides is RP9 (RGSALTHLP), derived from the white blood cells of crocodiles. In this research, three mutations were initially designed: LR-mut (RGSALTHLR), KR-mut (RGSAKTHLR), and WP-mut (RGSAWTHLP). The physicochemical characteristics of these peptides were assessed, revealing that KR-mut exhibited the most favorable biophysical properties. Subsequently, twenty molecular dynamics simulations were conducted for all peptides in pure water and at four different octanol concentrations (30 %, 50 %, 70 %, and 100 %) to evaluate their biophysical attributes. The findings from the 4000 ns molecular dynamics simulations revealed that the KR-mut exhibited reduced values of RMSD, the radius of gyration, solvent accessible surface area, and RMSF, while simultaneously showing an increased number of hydrogen bonds and interactions with water molecules. This peptide also showed the lowest free energy of solvation and the highest solubility across various octanol concentrations compared to the other peptides. The results obtained from the biophysical assessments and molecular dynamics simulations were consistent, resulting in the conclusion that KR-mut is expected to exhibit superior antibacterial activity compared to both the other mutated peptides and the wild type peptides. These theoretical findings were validated through experimental minimum inhibitory concentration (MIC) tests on gram-negative <em>Escherichia coli</em> and gram-positive <em>Staphylococcus aureus</em>. The outcomes of this study suggest that molecular dynamics simulations can effectively predict changes in the bactericidal efficacy of peptides at varying octanol concentrations, potentially enhancing the speed and efficiency of antimicrobial peptide design while reducing associated costs.</div></div>","PeriodicalId":8771,"journal":{"name":"Biochemistry and Biophysics Reports","volume":"41 ","pages":"Article 101953"},"PeriodicalIF":2.3,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143421103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need for advanced analytical tools to better understand the pathogenesis of cardiovascular disease (CVD) is critical due to its significant impact on public health. Clinicians often rely on indirect calculations of low-density lipoprotein (LDL) as a primary diagnostic indicator, which can oversimplify and overlook the complex changes in lipoprotein structure and function and therefore the complex etiology of CVD. Here it is demonstrated that dynamic light scattering (DLS) is sensitive and effective at measuring variation in lipoprotein size distributions following oxidative damage caused by peroxidation and nitration—two common physiological processes that play dual roles in both normal and pathogenic states. We establish the utility of DLS in detecting subtle variations in lipoprotein size, including potential aggregation and fission events resulting from chemical modifications.

The main strategy for treating melanoma is surgery to completely remove the lesion and its margins. However, for more advanced cases with a high recurrence rate, the preferred approach is to combine chemotherapy with immunotherapy treatments. Tumor-associated macrophages (TAMs) are the most abundant leukocytes in solid tumors. Current immunotherapy approaches target TAMs by inhibiting pro-tumoral TAMs and activating anti-tumoral TAMs, repolarizing them to the M1 phenotype. The antitumor and immunomodulatory activities of molecules derived from 1,2,4-oxadiazole, as demonstrated in the literature, highlight the potential of this class as a source of promising candidates for therapeutic applications. Thus, the present study aims to evaluate the antitumor and immunomodulatory effects of the synthetic derivative 1,2,4-oxadiazole, N-cyclohexyl-3-(3-methylphenyl)-1,2,4-oxadiazole-5-amine (1,2,4-oxadiazole derivative 2), in melanoma cells and murine Bone Marrow-Derived Macrophages (BMDMs). Cytotoxicity in B16–F10 and BMDMs cells was assessed using the (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) MTT method. 1,2,4-oxadiazole derivative 2 exhibited antiproliferative effects on both cell lines, being 2.6 times more selective for B16–F10. Necrosis was identified as the active induced death pathway. BMDMs isolated and exposed to 1,2,4-oxadiazole derivative 2 polarize to the M1 phenotype and induce TNF-α at a concentration of 64.34 μM. Exposure to melanoma murine supernatants also promotes M1 polarization. Supernatants containing traces of 1,2,4-oxadiazole derivative 2 (Supernatants B, C, and D) increased the percentage of M1 cells compared to Supernatant A, as well as elevated levels of nitrite, TNF-α, and IL-12. 1,2,4-oxadiazole derivative 2 combined with Supernatant A and 1,2,4-oxadiazole derivative 2 combined with LPS also resulted in higher M1 polarization, suggesting a synergistic effect on M1 polarization and TNF-α production.

For example, unirradiated neighbors of irradiated cells can produce signals that reduce DNA damages. This phenomenon, known as Radiation-Induced Rescue Effect (RIRE), has profound implications on the efficacy of radiotherapy. Using bystander cells co-cultured with mock-irradiated cells as a control, we demonstrated, for the first time, two types of RIRE. Conditioned medium from naïve by stander cells, i.e., cells not exposed to irradiated cells, could mitigate UV-induced DNA damages in human breast carcinoma MCF7 cells, as judged by phospho-H2AX and 53BP1 immunostaining. This protective effect could be further enhanced by the prior treatment of bystander cells with factors from UV-irradiated cells. We named the former effect “basal RIRE” and the latter “active RIRE” which were cell type-dependent. As bystanders, MCF7 showed a significant active RIRE, whereas THP1-derived macrophages showed a strong basal RIRE but no active RIRE. Interestingly, RIRE of macrophages could further be modulated by polarisation. The basal RIRE of macrophages was abolished by M1 polarisation, while M2 and Tumour Associated Macrophages (TAM) demonstrated pronounced basal and active RIRE. When mixtures of MCF7 cells and polarised macrophages were used as bystanders, the overall RIRE was dictated by macrophage phenotypes: RIRE was suppressed by M1 macrophages but significantly enhanced by M2 and TAM. This study shows a previously unappreciated role of the innate immune system in RIRE.
