Methods: Male C57BL/6 mice underwent TAC and received vehicle, low-dose curcumin (50 mg/kg), high-dose curcumin (200 mg/kg), high-dose curcumin plus a scrambled control antagomir, or high-dose curcumin plus anti-miR-29b treatments. Cardiac function was assessed by echocardiography. Fibrosis was evaluated by histology, collagen volume fraction, and hydroxyproline content. Expression of miR-29b, HDAC4, and fibrosis-related markers (Collai, Col3a1, TGF-β1) was measured by quantitative RT-PCR and Western blotting assays. Myocardial procollagen type I carboxyterminal propeptide was determined by ELISA, and HDAC4-specific enzymatic activity was assayed using a fluorogenic kit. Results: Curcumin improved cardiac function, reduced fibrosis, restored miR-29b expression, and suppressed HDAC4 expression and activity in a dose-dependent manner. Furthermore, curcumin decreased myocardial procollagen type I carboxy-terminal propeptide levels, confirming reduced collagen synthesis. Anti-miR-29b administration partially abrogated the antifibrotic and cardioprotective effects of curcumin. Conclusions: Curcumin attenuates pressure overload-induced cardiac fibrosis and dysfunction in a TAC mouse model via modulation of the miR-29b/HDAC4 axis and suppression of collagen synthesis.","PeriodicalId":8560,"journal":{"name":"Asian Pacific journal of tropical biomedicine","volume":"16 2","pages":"59-67"},"PeriodicalIF":0.0,"publicationDate":"2026-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Human umbilical vein endothelial cells (HUVECs) were injured by oxidized low-density lipoprotein for 24 h and treated with OA, and the levels of cell proliferation, migration, adhesion, and apoptosis were evaluated by BrdU staining, scratch healing assay, monocyte-endothelial cell adhesion assay and flow cytometry. The mice were fed with a high-fat diet to induce an atherosclerosis model, and treated with OA by gastric gavage. The mice were divided into the control group, the model group, and the OA administration group. The blood lipid and plaque formation in mice were detected. In addition, oxidative stress and mitochondrial structure and function changes in cells and mice were evaluated by transmission electron microscopy, JC-1 fluorescent probe, and Western blotting assays. The expression levels of proteins in the AMPK/Drp1 pathway were examined through Western blot. Results: OA markedly increased cell viability and migration rate of HUVECs, and decreased the adhesion rate of THP-1 cells and the apoptosis rate. OA significantly reduced serum lipid levels, such as total cholesterol and triglyceride, in mice and inhibited plaque formation in the aorta. OA also significantly increased the content of superoxide dismutase and catalase, alleviated mitochondrial damage, such as mitochondrial swelling and mitochondrial cristae reduction, reduced the number of mitochondria, increased adenosine triphosphate content, and significantly reduced p-Drp1 (Ser616)/Drp1, MFF and FIS1 levels, increased p-AMPK/AMPK levels, activated AMPK, and then regulated DRP1 activity. Conclusions: OA activates AMPK, which in turn regulates the activity of DRP1 to restore normal mitochondrial dynamics and reduce atherosclerosis.","PeriodicalId":8560,"journal":{"name":"Asian Pacific journal of tropical biomedicine","volume":"16 1","pages":"24-39"},"PeriodicalIF":0.0,"publicationDate":"2025-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The mechanism of AOF in treating DKD was explored by network pharmacological enrichment analysis, molecular docking, and molecular dynamics simulation. The effects of AOF on renal function and lipid deposition were assessed in a mouse model of DKD and high glucose-stressed HK-2 cells. Cell viability and lipid accumulation were detected by CCK8 and oil red O staining. The expressions of PPARα and fatty acid oxidation-related genes ( ACOX1 and CPT1A ) were detected by quantitative RT-PCR, Western blot, and immunofluorescence. Furthermore, PPARα knockdown was performed to examine the molecular mechanism of AOF in treating DKD. Results: Network pharmacological enrichment analysis, molecular docking, and molecular dynamics simulation showed that the active compounds in AOF targeted PPARα and thus transcriptionally regulated ACOX1 and CPT1A. AOF lowered blood glucose, improved dyslipidemia, and attenuated renal injury in DKD mice. AOF-containing serum accentuated high glucose-induced decrease in cell viability and ameliorated lipid accumulation. Additionally, it significantly upregulated the expression of PPARα, ACOX1, and CPT1A in both in vivo and in vitro experiments, which was reversed by PPARα knockdown. Conclusions: AOF may promote fatty acid oxidation via PPARα to ameliorate renal lipid deposition in DKD.","PeriodicalId":8560,"journal":{"name":"Asian Pacific journal of tropical biomedicine","volume":"15 1","pages":"11-23"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RT-qPCR was also used to determine S1RT1 mRNA expression. In addition, intracellular reactive oxygen species levels and antioxidant enzyme activities were evaluated. Results: Thrombopoietin treatment reversed doxorubicin-induced decline in H9c2 cell viability. It also increased SIRT1 and decreased p-p38 MAPK protein expressions. In addition, thrombopoietin significantly attenuated doxorubicin-induced apoptosis and oxidative stress, and enhanced antioxidant enzyme activities. However, silencing S1RT1 abrogated the protective effects of thrombopoietin, as evidenced by reduced cell viability and increased oxidative stress and reactive oxygen species levels.
