MSCs have become a promising candidate for cell therapy and tissue regeneration due to their unique properties, such as their ability to differentiate into multiple cell types, their capacity for expansion, self-renewal, and immune-regulatory effects. However, reports have brought attention to thrombosis-related complications associated with MSCs therapy in the last decade. As tissue factor (TF) is a powerful coagulation activator expressed by MSCs that stimulates the extrinsic coagulation pathway, we investigated the thrombotic properties of human umbilical cord MSCs (HUCMSCs) after knocking out the <i>TF</i> gene. MSCs populations that obtained from umbilical cord were cultured and expanded in the appropriate medium cell culture. The identity of the MSCs was verified through flow cytometry, and their ability to differentiate into osteogenic and adipogenic lineages. Two gRNAs for Exons 1 and 2 of the <i>TF</i> gene have been designed and cloned into px458 vector's backbone (pSpCas9 (BB)−2A-GFP). Following transfecting of gRNAs into HUCMSCs and successfully knocking out the <i>TF</i> gene using GAP-PCR, the impact of normal and knockout HUCMSCs on coagulation was assessed through prothrombin time (PT), <span>D</span>-dimer level, clotting time (CT), and turbidity assay. Furthermore, the impact of TF knockout (TFKO) on MMP19 expression was assessed. Our results revealed that the PT was prolonged and <span>D</span>-dimer level was decreased in TFKO group compared to normal HUCMSCs. These findings suggest that <i>TF</i> gene plays a crucial role in regulating coagulation in HUCMSCs. Also, a significant reduction in MMP19 expression was observed within the TFKO group.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 8","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142806193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to triggering cellular pathways, estrogen and progesterone carry out a number of biological processes that lead to neuroprotection. They might have an impact on learning and memory. One of estrogen's modest antioxidant properties is its direct scavenging of free radicals. The neurotrophic effect of estrogen and progesterone can be explained by their ability to rise the expression of the brain-derived neurotrophic factor (BDNF) mRNA.

Four groups of rats were treated as follows: control group, group receiving UDCA (100 mg/kg/day) for 14 days by gavage, group irradiated at 6 Gy, and group receiving UDCA post-irradiation for 14 days. The results revealed that gamma-irradiation (6 Gy) caused a substantial drop in the cerebral ACE2/Ang-(1–7)/Mas1 axis and remarkably increased the expression of cerebral inflammatory mediators: tumor necrosis factor-α (TNF-α), nuclear factor kappa-B (NF-κB), interleukin-6 (IL-6) and interleukin-1β (IL-1β) combined with significant elevation in cyclooxygenase-II (COX-II), (NADPH) oxidases (NOX4), lipooxygenase (LOX) activities and nitric oxide (NO) content.

Irradiated rats’ brain sections underwent histological investigation using hematoxylin and eosin staining, which revealed cellular damage and a pathological appearance. The administration of UDCA inverts these unusual alterations. In conclusion, UDCA treatment efficiently normalizes the above-mentioned pathological abnormalities and avoids the development of IRR-associated neurological dysfunction by upregulating the beneficial axis of RAS in the brain.

TNK2 participates in tumorigenesis, and TNK2 activation has been found in various cancers; therefore, TNK2 is a promising target for cancer chemotherapy. While the TNK2 inhibitor XMD16-5 is highly selective, it inhibits cytokinesis at higher concentrations by targeting Aurora B kinase, a key enzyme for cell division. Cytokinesis failure frequently generates polyploid cells, and the surviving polyploid cells risk leading to cancer development and malignant progression via chromosome instability. In this study, to investigate the possibility that (R)−9bMS, a TNK2 inhibitor structurally related to XMD16-5, drives malignant progression by inducing abnormal cell division, we examined its effects on cell division, Aurora B autophosphorylation, and colony formation. Cell count results showed a reduction in the number of A431, HeLa S3, HCT116, and MCF7 cells upon TNK2 inhibitor treatment. Microscopic observation indicated the formation of multinucleated and nucleus-enlarged cells. An increase in DNA content was confirmed with flow cytometry, which was underpinned by an increased number of centrosomes. Time-lapse imaging revealed mitotic failure, such as mitotic slippage and cytokinesis failure, as a cause of polyploidization. Of note, TNK2 knockdown significantly increased multinucleated cells, but the effect was quite weak, suggesting that TNK2 inhibition may only partially contribute to mitotic failure and polyploidization. Expectedly, Aurora B phosphorylation was reduced by (R)−9bMS like XMD16-5, but not by TNK2 knockdown. Collectively, TNK2 inhibitors (R)−9bMS and XMD16-5 induce polyploidization via mitotic failure caused by the inhibition of Aurora B kinase rather than TNK2. Notably, (R)−9bMS treatment promoted anchorage-independent colony formation, a hallmark of cancer. Our findings suggest that (R)−9bMS at a high concentration risks promoting cancer development or malignant progression. Therefore, caution should be used when using TNK2 inhibitors for cancers where TNK2 activation is not the transforming mutation and higher concentrations of TNK2 inhibitors are required to slow proliferation.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 8","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142784234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the ethanolic extract of <i>Verbascum gimgimense</i> (VG) was analyzed for its cytotoxic, apoptotic, antioxidant, and enzyme inhibitory properties, as well as its phenolic and lipophilic compounds. The phenolic compounds in the extract were identified using Exactive Plus Orbitrap HPLC-HRMS, while the lipophilic components were characterized by GC-MS analysis. The Neutral Red Uptake (NRU) cell viability assay and colony formation assay were performed to assess the antiproliferative and anti-colony survival effects of VG on the A549 human lung adenocarcinoma cell line. Additionally, a wound healing assay measured cell migration, and the apoptotic process was evaluated using Caspase-3 ELISA and acridine orange/ethidium bromide staining. Protein expression levels were determined by western blot analysis. DPPH, ABTS FRAP, and CUPRAC assays were used to determine free radical scavenging, reducing power, and metal chelating activities, respectively. VG was rich in dominant phenolic components, including benzoic acid (6.809 mg/g extract), phloretic acid (1.279 mg/g extract), luteolin 7-rutinoside (2.799 mg/g extract), luteoloside (3.300 mg/g extract), kuromanine (3.456 mg/g extract), and rutin hydrate (2.015 mg/g extract). Major fatty acids identified in VG included palmitic acid (17.3%), stearic acid (2.99%), linoleic acid (9.44%), and α-linolenic acid (26.48%).

The motivation arises from the reported therapeutic effects of the plant and the desire to pinpoint the compounds responsible for these benefits. Gas chromatography–mass spectrometry spectrophotometric analysis was employed to characterize chemical constituents in the aqueous extracts (infused aqueous extract and macerated aqueous extract) and fractions (cyclohexane fraction, ethyl acetate fraction, butanol fraction, remaining aqueous fraction) of <i>C. ambrosioides</i>. Animal models were used to examine the analgesic activity, while α-glucosidase and α-amylase enzyme assays were used to investigate the antidiabetic effect. Throughout the investigation, several chemical families were found, including phenolic compounds, alcohols, acids, terpenes, steroids, and others. Trans-ascaridol glycol, palmitic acid, phenol, octadecadienoic acid, isoascaridol, eicosanoic acid, 2-methoxy-4-vinyl phenol, mexiletine, and thymol were among the significant chemicals found.
