Therefore, we aimed to identify new compounds with a potential to increase proliferation and differentiation of osteoblasts. Methods: Cellular and molecular assays, such as ALP activity, alizarin staining, and flow cytometry were employed to check the effect of TMF on osteogenesis. Moreover, gene expression analysis of certain important genes and transcriptional factors was also performed. Results: Our findings report for the first time that 7,3′,4′-trimethoxyflavone is capable of enhancing proliferation, and differentiation in osteoblast cells. Results from flow cytometry analysis also indicated that TMF increases the number of cells in S-phase. Furthermore, treatment with TMF altered the expression of osteogenic genes, OCN and Axin-2 indicating possible activation of Wnt signaling pathway. Conclusion: Taken together, this study identified that 7,3′,4′-trimethoxyflavone has the potential to enhance osteoblast proliferation and differentiation, possibly due to the activation of Wnt/β-catenin pathway. Thus, demonstrating TMF as naturally occurring agent to promote osteogenesis and prevention of bone fragility, and related disorders.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141866240","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}

In our current work, we have explored the oncogenic properties and the underlying pathophysiology of IMPDH2 in hepatoblastoma (HB). Methods: To investigate IMPDH2 expression in HB tissues and prognostic significance in HB patients, gene expression profiling interactive analysis (GEPIA) has been adopted. Immunohistochemistry has also helped to validate the protein expression of IMPDH2 in HB tissues. The effect of IMPDH2 overexpression or depletion on the proliferation of Hepatoblastoma cells in vitro has been evaluated by CCK8 assays and colony formation assays. Xenograft tumor growth of mice has been detected. Luciferase reporter assays have been conducted to determine the interaction of IMPDH2 and JunB, which was further asserted by pharmacological inhibition of JunB. Results: IMPDH2 was highly expressed in HB tissues. Experimentally, the proliferation and colony formation of HuH6 cells were increased by IMPDH2 overexpression. Conversely, genetic inactivation of IMPDH2 impaired the proliferative efficiency and colony-forming rate of HepG2 cells. Besides, the luciferase reporter assay validated IMPDH2 overexpression to be associated with enhanced JunB transcriptional activity, while its activity was diminished in the case of IMPDH2 depletion. JunB inhibitor neutralized the IMPDH2-mediated increased phosphorylation of JunB. Conclusion: Our findings, thus, suggest that IMPDH2 exhibits its oncogenic role in HB partially via JunB-dependent proliferation.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139949549","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}

Ischemia reduces ATP production and intracellular pH, reducing oxidative reactions, increasing lactic acid release, and activating anaerobic metabolism. Reperfusion restores aerobic respiration and increases ROS production, leading to malfunction of transmembrane transport, activation of proteases, DNA dissolution, and protein denaturation, leading to apoptotic cell death. Nrf2 is a transcription factor that regulates cellular inflammation and oxidative responses. It is activated by oxidants and electrophiles and enhances detoxifying enzyme expression, maintaining redox homeostasis. It also activates ARE, which activates several ARE-regulated genes that favor cell survival by exhibiting resistance to oxidants and electrophiles. Nrf2 regulates the antioxidant defense system by producing phase II and antioxidant defense enzymes, including HO-1, NQO-1, gglutamylcysteine synthetase, and rate-limiting enzymes for glutathione synthesis. Nrf2 protects mitochondria from damage and supports mitochondrial function in stress conditions. Resveratrol is a stilbene-based compound with a wide variety of health benefits for humans, including antioxidant, anticarcinogenic, antitumor, and estrogenic/antiestrogenic. Resveratrol protects against IRI through several signaling pathways, including the Nrf2/ARE pathway. Here, we review the studies that investigated the mechanisms of resveratrol protection against IRI through modulation of the Nrf2 signaling pathway.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139763786","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}

The potential adverse effects of nicosulfuron on animals, including reproductive toxicity, have garnered attention. Objective:: The study aimed to evaluate the reproductive toxicity of nicosulfuron in male mice. Methods:: Male mice were orally administrated with three different concentration gradients (350, 700, and 1400 mg/kg) of nicosulfuron for 35 days. The investigation delved into sperm quality, testicular structures, and expression of cleaved caspase-3 and NF-κB p65 of the testes. Results:: The finding unveiled a correlation between nicosulfuron exposure and detrimental effects on sperm quality and alteration of testicular structure. Notably, parameters, such as sperm survival rate (SUR) and sperm motility (MOT), exhibited a decline in relation to increasing nicosulfuron dosages. Moreover, in the mice subjected to higher doses of nicosulfuron, elevated expression of cleaved caspase-3 and NF-κB p65 was observed in the testes. Interestingly, we also observed an increase of NF-κB p65 expression in the mice exposed to the nicosulfuron. Conclusion:: Our research revealed that exposure to nicosulfuron resulted in compromised sperm quality and alterations in testicular structure. The correlation between nicosulfuron and apoptosis, especially via the NF-κB pathway, provided significant insights into the mechanisms underpinning these detrimental effects. These findings significantly enhance our comprehension of the potential hazards associated with nicosulfuron exposure and its impacts on the reproductive health of animals.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139763953","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}

Increasing evidence has shown the significant functions of microRNAs in the cardiovascular system and has highlighted their potential application as a new era of diagnostic and therapeutic targets for CVD that can improve the prognosis and life expectancy of patients. Among more than 2,000 microRNAs, microRNA-21 [miR-21] is highly expressed in human hearts and has earned the interest of researchers as a potential biomarker in a wide range of common heart conditions. Here, we summarized recent research progress regarding the significant role of miR-21 in CVD, focusing on cardiotoxicity, heart arrhythmias, cardiomyopathies, and hypertension. Several signaling pathways [TGF-β1/Smad2 signaling, FGFR1/FGF21/PPARγ, NF-κB/miR-21/SMAD7, miR-21/SPRY1/ERK/mTOR …] and molecular targets [BTG2, PDCD4, PTEN, STAT3…] were reported to be controlled, at least partially, by miR-21 and are linked to CVD pathogenesis. Most investigations highlighted miR-21 cardioprotective functions in heart injury, while some other studies showed that this miR is elevated in the serum/tissue of patients, promoting fibrosis and cardiac dysfunction. This dual role can be explained by the fact that miR-21 has multiple regulatory functions depending on the microenvironment, downstream signaling, and target genes, which indicates that cell-type-specific investigations should receive more attention. With further investigations, miR-21 can be considered a novel tailored therapy with favorable outcomes.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139588056","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}
