Collagen triple helix repeat containing 1 (CTHRC1), a migration-promoting protein, acts as a tumor-promoting factor in malignant tumors. However, functions and mechanisms of CTHRC1 in children with IBD remain unclear. This study aimed to determine the effects and mechanisms of CTHRC1 on dextran sodium sulfate (DSS)-treated HT-29 cells. HT-29 control cells were exposed to 2% DSS to develop an in vitro IBD model. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blotting were used to assess CTHRC1 expression in serum of children with IBD and HT-29 cells. Cell viability and apoptosis were assessed using MTT and flow cytometry (FCM). Expressions of cleaved-Caspase3 and Caspase3 were determined by western blotting. The cytokine production (TNF-α, IL-1β and IL-6) in HT-29 cells was measured by ELISA assay. Activation or inactivation of NF-κB signaling pathway was confirmed by western blot assay. Results showed that CTHRC1 expression was upregulated in the IBD serum and HT-29 control cells. The level of CTHRC1 was lower in CTHRC1-siRNA transfected cells than in control siRNA-treated cells. Notably, silence of CTHRC1 markedly enhanced HT-29 cells viability, decreased apoptotic cells, suppressed cleaved-Caspase3 expression, inhibited cleaved-Caspase3/Caspase3 ratio, reduced the production of inflammatory cytokines, and blocked NF-κB signaling pathway induced by DSS. However, these effects were reversed following diprovocim treatment. Thus, that knockdown of CTHRC1 alleviated DSS-induced HT-29 cell injury by inhibiting the NF-κB signaling pathway in vitro, providing a new therapeutic target for IBD in children.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-025-00705-x.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 2","pages":"44"},"PeriodicalIF":2.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11759733/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143045406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The isometric tension of isolated aortic rings was assessed by generating a dose-response curve (DRC) for Ang 1-7 using a PowerLab data acquisition system. Accordingly, three experimental sets were carried out. In the first set the aortic rings were exposed MEL and MEL agonist ramelteon (RAM) and MEL antagonist luzindole (LUZ). In the second set, the aortic rings were exposed to various non-selective calcium activated potassium channel (K_Ca) blockers, including tetraethylammonium (TEA), a small and large-conductance calcium-activated K⁺ [(SK_Ca) and (BK_Ca)] channels blocker charybdotoxin (ChTx) and intermediate calcium-activated K⁺ channel (IK_Ca) blocker clotrimazole (CLT). In the third set, the aortic rings were exposed to various selective K⁺ channels blockers, including the selective blocker of K_ATP channel, glibenclamide (Glib), 4-aminopyridine (4-AP), a selective blocker of K_v channels and BaCl₂, delayed inward rectifier K⁺ channels (K_ir) blocker. The results highlight the significant role of MEL in modulating vascular reactivity, particularly in the DM aorta. By enhancing the vasorelaxant effects of Ang 1-7 through mechanisms involving its receptors and antioxidant activities, MEL demonstrates its potential to counteract oxidative stress and VED associated with diabetes.

This study employs RNA sequencing to identify genes to be used in concert with CD264 as a molecular profile of aging MSCs at a clinically relevant culture passage. CD264^- and CD264⁺ populations were isolated by fluorescence-activated cell sorting from passage 4 MSC cultures. CD264⁺ MSCs exhibited an aging phenotype relative to their CD264^- counterpart. Donor-matched CD264^-/+ mRNA samples from 5 donors were subjected to pair-ended, next-generation sequencing. An independent set of 5 donor MSCs was used to validate differential expression of select genes with quantitative reverse transcription PCR. Pairwise differential expression analysis identified 2,322 downregulated genes and 2,695 upregulated genes in CD264⁺ MSCs relative to donor-matched CD264^- MSCs with a Benjamini-Hochberg adjusted <i>p</i>-value (BH <i>p</i> _<i>adj</i> ) < 0.1. Nearly 25% of these genes were unique to CD264^-/+ MSCs and not differentially expressed at a significance level of BH <i>p</i> _<i>adj</i>  < 0.1 in previous RNA sequencing studies of early- vs. late-passage MSCs. Least Absolute Shrinkage and Selection Operator regression identified microtubule-associated protein 1A (<i>MAP1A</i>) and pituitary tumor-transforming gene 1 (<i>PTTG1</i>) as predictive genes of CD264⁺ MSCs. Combined <i>MAP1A</i> and <i>PTTG1</i> expression correctly classified CD264 status of MSC samples with an accuracy of 100%.

However, due to its laborious and low-throughput characteristics, only a limited number of clones can be evaluated. To attain high-throughput fed-batch culture evaluation, a shaken 24-deep-well plate (24 DWP) culture process was developed. 24 DWP culture allows multiple plates to be run in parallel, and is therefore suitable for early-stage screening. One challenge of well plate culture is the nonuniform evaporation rate among wells, which may result in unnecessary bias on clone evaluation. The 'sandwich lid system' introduced here provides a uniform evaporation rate, and showed no significant difference in cell culture performance by well location. 192 antibody-producing CHO clones were evaluated by 24 DWP fed-batch culture, and 30 clones were selected. On comparison of clone sets selected by 24 DWP fed-batch culture and the conventional scheme, average antibody concentration in SF fed-batch culture was 3.6 g/L and 2.9 g/L, respectively. 24 DWP fed-batch culture process showed a high correlation ratio with SF fed-batch culture in antibody productivity and similar cell culture characteristics.

In this study, we aimed to explore the impact of Zinc supplementation on pyroptosis and inflammation in a cigarette smoke (CS)-induced COPD mouse model, as well as the underlying mechanisms. The COPD mouse model was established through CS exposure, and mouse pulmonary epithelial cells (MLE-12) were exposed to cigarette smoke extract (CSE) to further validate the effects of Zinc supplementation. CS exposure resulted in significant alveolar wall damage, increased thickening of the alveolar walls, and elevated levels of interleukin-1β (IL-1β), IL-6, IL-18, and tumor necrosis factor-α (TNF-α) in the lung tissues of COPD mice. However, treatment with dexamethasone (a positive control) or Zinc supplementation alleviated these damages. Furthermore, the expressions of pyroptosis markers, including NLRP3, cleaved-Caspase-1, and GSDMD-N proteins, were upregulated in the lung tissues after CS exposure. Zinc supplementation, however, reversed these changes. Additionally, Zinc supplementation upregulated the protein expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), hemeoxygenase-1 (HO-1), and quinone oxidoreductase-1 (NQO-1), and promoted the ubiquitination of Kelch-like ECH-associated protein 1 (Keap1) mediated by tripartite motif 25 (TRIM25) in the lung tissues of CS-induced mice. Importantly, the Nrf2 signaling inhibitor ML385 abolished the beneficial effects of Zinc in CS-exposed mice. Similar results were observed in MLE-12 lung epithelial cells exposed to CSE.

This review summarizes recent research on using PROTACs as a therapeutic strategy for brain tumors, focusing on their mechanism, benefits, limitations, and the need for optimization. The review draws from a comprehensive search of peer-reviewed literature, scientific databases, and clinical trial databases. Articles published up to the knowledge cutoff date up to 14 April 2023 were included. Inclusion criteria covered PROTAC-based brain tumor therapies, including preclinical and early clinical studies, with no restrictions on design or publication type. We included studies using in vitro, in vivo brain tumor models, and human subjects. Eligible treatments involved PROTACs targeting proteins linked to brain tumor progression. We evaluated the selected studies for methodology, including design, sample size, and data analysis techniques. A narrative synthesis summarized key outcomes and trends in PROTAC-based brain tumor therapy. Recent research shows PROTACs selectively degrade brain tumor-related proteins with minimal off-target effects. They offer enhanced potency, selectivity, and the ability to combat resistance compared to traditional inhibitors. PROTACs hold promise for brain tumor treatment offering advantages over traditional inhibitors, but more research is needed to refine their mechanisms, efficacy, and safety.
