The underlying mechanisms of RIF remain unclear. Recent studies have identified distinct expression patterns of circular RNAs (circRNAs) in the endometrial tissues of individuals with RIF. The objective of this research is to evaluate the expression of six candidate circRNAs in the plasma of RIF patients.Methods: The study included a total of sixty participants, comprising 30 RIF patients and 30 age-matched controls. Specific primers were designed for six circRNAs (hsa_circ_0001713, hsa_circ_0004121, hsa_circ_0030162, hsa_circ_0034642, hsa_circ_0034762, and hsa_circ_0092337), and expression analysis was carried out by RT-qPCR. Blood samples were collected from individuals during the implantation window, and cell-free RNA was extracted from plasma. Statistical analysis was performed using Graphpad Prism software.Results: Control and RIF groups had mean ages of 34.68 ± 6.2 and 36.80 ± 3.8 years, respectively. Plasma from RIF patients showed significant downregulation of hsa_circ_0030162 (p=0.02) and upregulation of hsa_circ_0004121 (p=0.003) compared to controls. Bioinformatic analysis predicted hsa-miR-125a-3p and hsa-miR-125a-5p as potential targets of hsa_circ_0030162 and hsa_circ_0004121, respectively.Conclusions: This study demonstrates the differential plasma expression of hsa_circ_0030162 and hsa_circ_0004121 in RIF patients, consistent their expression in endometrial tissue. These circRNAs may contribute to RIF pathogenesis.

The condition is characterized by an angiogenic imbalance, which has adverse effects on fetal development and contributes to an increased risk of cardiovascular disease in the long term. This study aims to explore the connection between sterile inflammation mediated by HMGB1 and angiogenic imbalance in PE by examining key markers such as HMGB1, VEGF, Decorin, and TGF-β.Methods: In an animal model of PE, we measured the levels of HMGB1, VEGF, Decorin, and TGF-β in plasma, placenta, and heart tissues using ELISA. Additionally, Decorin levels were assessed through immunofluorescence in trophoblasts.Results: We found that levels of Decorin and TGF-β were significantly elevated in the plasma, placenta, and heart tissues of PE animals compared to non-pregnant and pregnant controls, whereas VEGF levels were reduced. Treatment with Glycyrrhizic acid (GA) restored the expression levels of these markers to more normalized values in the PE groups.Conclusions: Our findings indicate that HMGB1 plays a critical role in preeclampsia by mediating the upregulation of anti-angiogenic factors like Decorin and the downregulation of angiogenic factors like VEGF.

Early detection is crucial for improving survival rates. Liquid biopsies, specifically analyzing circulating tumor-educated platelets (TEPs), have emerged as a promising tool for early CRC detection and monitoring treatment efficacy. This study investigated the expression levels of two specific circRNAs, hsa_circ_0004771 and hsa_circ_0019120, in the platelets of patients with CRC, advanced polyps, and healthy controls.Methods: Blood samples were obtained from 25 individuals with CRC, 25 individuals with advanced polyps, and 25 healthy controls.

Antioxidants, like curcumin (Cur), can inhibit these factors. In this research, the effect of curcumin on the expression and activity of two MMP enzymes, MMP-14 and MMP-17, which are involved in the carcinogenesis of mice after chronic exposure to thioacetamide, is investigated.Methods: In this study, 30 mice were divided into six groups and studied for 4 months. The first group, control; the second group, curcumin; the third group, TAA; the fourth group, TAA and curcumin simultaneously; the fifth group, first treated with TAA for 2 months and then curcumin; and finally, the sixth group, first treated with curcumin for 2 months and then TAA.

Using Escherichia coli strains for expression, we cloned the GFP-ADT-6 construct, which provides a solid foundation for our study's methodology.Results: Our molecular simulations showed that the linker between GFP and ADT-6 maintains the fusion protein's integrity and provides flexibility in receptor interaction. Permeability experiments revealed that ADT-6 markedly reduced transepithelial electrical resistance (TEER) and significantly increased GFP transfection in Caco-2 cell monolayers dose-dependently. Results of ELISA confirmed these findings, showing high GFP levels in the lower compartment of Transwell systems treated with GFP-ADT-6.Conclusions: This study demonstrates the potential of ADT-6 to deliver proteins from the paracellular route, enhance the bioavailability of pharmaceutical drugs by altering cell-cell interactions, and provide new opportunities for oral drug delivery strategies.","PeriodicalId":45319,"journal":{"name":"Reports of Biochemistry and Molecular Biology","volume":"13 3","pages":"349-357"},"PeriodicalIF":1.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12050061/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144020691","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}

Their OMVs were then isolated and characterized using dynamic light scattering (DLS) and scanning electron microscopy (SEM). The effects of E. coli-derived OMVs on colorectal cancer were evaluated in vitro and in vivo using a colorectal tumor model in nude mice.Results: Obtained results showed that E. coli probiotic strains released spherical-shaped vesicles ranging from 5 to 200 nm. E. coli-derived OMVs showed that in the untreated group, a large portion of the tumor tissue continued to grow, with only a few cells undergoing apoptosis. Conversely, the OMV-treated group exhibited a higher number of apoptotic cells, highlighting the anticancer effects of E. coli-derived OMVs in colorectal cancer.Conclusions: These results demonstrated that E. coli-derived OMVs can be employed as a potential treatment for colorectal cancer with minimal adverse effects.

Nanocomposites were formed through a condensation reaction with polyacrolein. Characterization techniques included Atomic Force Microscopy (AFM), Fourier Transform Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), and Differential Scanning Calorimetry (DSC). Cytotoxicity was evaluated through in vitro assays using human dermal fibroblasts (HdFn) and A172 glioblastoma cells.Results: AFM analysis showed nanoparticle sizes of 19.36 nm for Ag2O and 66.89 nm for CuO, while TEM images revealed nonhomogeneous spherical nanocomposites. FT-IR and XRD confirmed the successful incorporation of nanoparticles into the polymer matrix. TGA and DSC results demonstrated thermal stability and transitions of the nanocomposites. Cytotoxicity assays indicated significant inhibition of A172 glioblastoma cell proliferation with minimal impact on normal fibroblast cells, suggesting selective cytotoxicity.Conclusions: The polymer nanocomposites incorporating moringa-extracted CuO and Ag2O nanoparticles exhibited promising selective cytotoxicity against glioblastoma cells, indicating their potential use as anticancer agents. Further studies on in vivo applications and long-term stability are warranted to advance their biomedical use.","PeriodicalId":45319,"journal":{"name":"Reports of Biochemistry and Molecular Biology","volume":"13 3","pages":"405-419"},"PeriodicalIF":1.6,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12050063/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144019720","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}
