Excessive exposure to the pesticide copper sulfate (CuSO4) was associated with toxic effects. This study aims to evaluate the efficacy of Coenzyme Q10 (CoQ10) and its liposomal form (L-CoQ10) against myocardial injury induced by CuSO4, pinpointing the involvement of redox imbalance, TLR-4/NF-κB signaling and apoptosis. Cardiac injury in rats was induced by daily oral doses of CuSO4 for 7 days, the rats were treated orally with either CoQ10 or L-CoQ10 concurrently with CuSO4 for 7 days. Elevated serum cTnI, CK-MB and LDH were observed in CuSO4-intoxicated animals. Additionally, cellular antioxidant biomarkers were decreased and the expression levels of cardiac MDA, TLR-4, NF-κB, IL-6, IL-1β, and TNF-α were upregulated. CoQ10 and L-CoQ10 prevented myocardial injury and decreased the levels of both MDA and pro-inflammatory cytokines. CoQ10 and L-CoQ10 enhanced antioxidant capacity and Bcl-2, and downregulated caspase-3, Bax, p53, RIP3, MLKL, caspase-8 and TLR-4/NF-κB signaling. In conclusion, CoQ10 and L-CoQ10 effectively prevent CuSO4 cardiotoxicity in rats. Attenuation of redox imbalance, TLR-4/NF-κB signaling, pro-inflammatory response, and necroptosis along with enhancement of antioxidant response mediated their cardioprotective efficacy. CoQ10 could be valuable in protecting people vulnerable to Cu toxicity.</p>","PeriodicalId":9802,"journal":{"name":"Cellular and molecular biology","volume":"71 1","pages":"118-124"},"PeriodicalIF":1.5,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143254794","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}

Spinster homolog 2 (SPNS2), a protein responsible for S1P transport, regulates sphingolipid metabolism and signaling in endothelial cells to maintain vascular homeostasis. In the present work, we investigated the involvement of SPNS2 in endothelial mesenchymal transition. Knocking down SPNS2 in endothelial cells resulted in significant phenotypic changes, marked by a decrease in endothelial markers (CD31, VE-cadherin) and an increase in mesenchymal markers (Vimentin, α-SMA), confirming the occurrence of EndMT. Notably, SPNS2 knockdown leads to alterations in sphingolipid metabolism, most prominently marked by a significant increase in sphingomyelin (SM) levels. Similar cellular alterations were observed with the exogenous addition of SM, leading to the transition of endothelial cells from a cobblestone-like morphology to a dispersed, spindle-shaped form. In contrast, the exogenous addition of sphingomyelinase, which degrades SM, was able to reverse the endothelial-to-mesenchymal transition induced by SPNS2 knockdown. Mechanistically, our study suggests that SPNS2 knockdown promotes endothelial-to-mesenchymal transdifferentiation by upregulating SMS2 expression, which subsequently enhances sphingomyelin synthesis.</p>","PeriodicalId":9802,"journal":{"name":"Cellular and molecular biology","volume":"71 1","pages":"135-141"},"PeriodicalIF":1.5,"publicationDate":"2025-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143254718","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}

Consequently, there is a pressing need for a rapid and precise method to identify bacterial contaminants in drinking water. The objective of this study was to investigate the protein profiles of various bacterial species present in water through the application of protein fingerprinting (PF) and real-time polymerase chain reaction (real-time PCR) techniques, as well as to evaluate their antimicrobial resistance. A total of two hundred water samples were collected from five distinct locations within the Qassim region of Saudi Arabia. Bacterial isolates were identified using a protein fingerprinting analytical technique (PFAT), which was subsequently confirmed by real-time PCR. The Kirby-Bauer method was employed to assess antibiotic resistance among the bacterial isolates. Out of the 200 water samples analyzed, PFAT successfully identified 123 bacterial isolates, with the most frequently isolated species being 48 Pseudomonas aeruginosa (P. aeruginosa), 17 Staphylococcus aureus (S. aureus), and 16 Escherichia coli (E. coli). All waterborne bacterial isolates were accurately identified 100% of the time, achieving a score of 2.00 or higher. The results from real-time PCR indicated that 87.5% of P. aeruginosa isolates were positive for the oprI gene, all S. aureus isolates were positive for the nuc gene, and 93.75% of E. coli isolates were positive for the fliC gene. P. aeruginosa isolates demonstrated a high level of resistance to aztreonam (64.6%), while S. aureus exhibited significant resistance to cefoxitin and cefepime (88.24%), followed by aztreonam (82.35%) and amoxicillin-clavulanate (70.6%). E. coli isolates showed complete resistance to ampicillin (100%), with high resistance also observed against amoxicillin-clavulanate and cefoxitin (87.5%), and cefepime (81.25%).

For this purpose, the renal IRI model was induced by left renal pedicle clamping for 45 min and right nephrectomy in mice. All mice were intraperitoneally injected with vehicle or IL-38. Renal histology, function, apoptosis and inflammatory cytokines were assessed. mRNAs were detected by Real-time PCR. The proteins were measured by Western blot. Results showed that the expression of IL-38 mRNA and protein in kidney tissue was significantly increased at 6 h and reached a peak at 24 h after renal IRI, along with the kidney dysfunction. IL-38 significantly decreased renal IRI, as reflected by the attenuation of renal dysfunction, tubular damage and cellular apoptosis. Thus, IL-38 markedly ameliorated the survival rate after renal IRI.
