Abstract
Dihydrotanshinone I (DHT) is a natural component in Salvia miltiorrhiza and has been widely researched for its multiple bioactivities. However, poor solubility and biocompatibility of DHT limit its desirable application for clinical purposes. Herein, DHT was encapsulated with bovine serum albumin (BSA) to enhance bioavailability. Compared to free DHT, DHT-BSA NPs (nanoparticles) showed an improved solubility in normal saline and increased protection against hydrogen peroxide-induced oxidative damage in PC12 cells. In addition, DHT-BSA NPs administered by intravenous injection displayed a significant efficacy in the middle cerebral artery occlusion/reperfusion models, without any impact on the cerebral blood flow. In summary, DHT-BSA NPs show an enhanced bioavailability compared with free DHT and a successful penetration into the central nervous system for stroke therapy, demonstrating their application potential in cardio-cerebrovascular diseases.

Che Y, Wang Z, Yuan Y, Zhou H, Wu H, Wang S, Tang Q. By restoring autophagic flux and improving mitochondrial function, corosolic acid protects against Dox-induced cardiotoxicity. Cell Biol Toxicol 2021; 38:451-467. [PMID: 34296331 DOI: 10.1007/s10565-021-09619-8] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Accepted: 05/23/2021] [Indexed: 01/02/2023]
Abstract
Despite effective anticancer effects, the use of doxorubicin (Dox) is limited due to its side effects as cardiotoxicity. Corosolic acid (CRA) is a pentacyclic triterpene acid isolated from Lagerstroemia speciosa L. (Banaba) leaves, and it has also been shown to improve myocardial hypertrophy and myocardial infarction which expected to be used in clinical pharmaceuticals. The purpose of this study was to explore whether CRA can improve myocardial injury caused by Dox and to clarify potential mechanisms. C57 BL/6J mice and AMPKα2 knockout mice were given a single intraperitoneal (i.p.) injection of Dox (5 mg/kg) every week for 4 weeks, while normal saline (NS) was used as control. Mice were given CRA (10 mg/kg or 20 mg/kg) or equal volumes of normal saline daily after the first time i.p. injection of Dox. After 4 weeks, echocardiography, gravimetric, hemodynamic, histological, and biochemical analyses were conducted. After Dox injury, compared with the control group, CRA increased the survival rate of mice, improved the cardiac function, decreased the oxidative stress, and reduced the apoptosis. CRA may function by promoting transcription factor EB (TFEB) nuclear translocation and thus restoring autophagic flux. We also observed that CRA protected mitochondrial structure and function, which may benefit from oxidative stress reduction or TFEB activation. In vitro, the protective effect of CRA is reversed by TFEB deletion. Then, we evaluated the expression of AMPKα2/mTOR C1 signaling pathway, the main pathway of TFEB activation. In vivo and in vitro, CRA promoted TFEB nuclear translocation by activating AMPKα2/mTOR C1 signaling, while ablating AMPKα2 reversed these results and accompanied with a decrease in the ability of CRA to resist Dox-induced cardiotoxicity. Thus, we suggested that CRA activated TFEB in an AMPKα2-dependent manner to protect against Dox cardiotoxicity. This study confirms the role and mechanism of CRA in the treatment of Dox-induced cardiac injury. Dox-induced damage to autophagy includes autophagosomes maturation disorders and autophagolysosomes acidification defects, CRA restored autophagic flux, and promoted lysosomal degradation by activating TFEB in an AMPKα2-depended manner, stabilized mitochondrial function, ultimately protected against Dox-induced cardiotoxicity.

Date Palm Pollen Extract Avert Doxorubicin-Induced Cardiomyopathy Fibrosis and Associated Oxidative/Nitrosative Stress, Inflammatory Cascade, and Apoptosis-Targeting Bax/Bcl-2 and Caspase-3 Signaling Pathways. Animals (Basel) 2021; 11:ani11030886. [PMID: 33804672 PMCID: PMC8003775 DOI: 10.3390/ani11030886] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 03/14/2021] [Accepted: 03/17/2021] [Indexed: 12/15/2022] Open
Abstract
Simple Summary The use of date palm pollen ethanolic extract (DPPE) is a conventional approach in improving the side-effects induced by Doxorubicin (DOX).DPPE mitigated DOX-induced body and heart weight changes and ameliorated DOX-induced elevated cardiac injury markers. In addition, serum cardiac troponin I concentrations (cTnI), troponin T (cTnT), and N-terminal NBP and cytosolic (Ca+2) were amplified by alleviating the inflammatory and oxidative injury markers and decreasing histopathological lesions severity. DPPE decreased DOX-induced heart injuries by mitigating inflammation, fibrosis, and apoptosis through its antioxidant effect. To reduce DOX-induced oxidative stress injuries and other detrimental effects, a combined treatment of DPPE is advocated. Abstract Doxorubicin (DOX) has a potent antineoplastic efficacy and is considered a cornerstone of chemotherapy. However, it causes several dose-dependent cardiotoxic results, which has substantially restricted its clinical application. This study was intended to explore the potential ameliorative effect of date palm pollen ethanolic extract (DPPE) against DOX-induced cardiotoxicity and the mechanisms underlying it. Forty male Wistar albino rats were equally allocated into Control (CTR), DPPE (500 mg/kg bw for 4 weeks), DOX (2.5 mg/kg bw, intraperitoneally six times over 2 weeks), and DPPE + DOX-treated groups. Pre-coadministration of DPPE with DOX partially ameliorated DOX-induced cardiotoxicity as DPPE improved DOX-induced body and heart weight changes and mitigated the elevated cardiac injury markers activities of serum aminotransferases, lactate dehydrogenase, creatine kinase, and creatine kinase-cardiac type isoenzyme. Additionally, the concentration of serum cardiac troponin I (cTnI), troponin T (cTnT), N-terminal pro-brain natriuretic peptide (NT-pro BNP), and cytosolic calcium (Ca+2) were amplified. DPPE also alleviated nitrosative status (nitric oxide) in DOX-treated animals, lipid peroxidation and antioxidant molecules as glutathione content, and glutathione peroxidase, catalase, and superoxide dismutase activities and inflammatory markers levels; NF-κB p65, TNF-α, IL-1β, and IL-6. As well, it ameliorated the severity of histopathological lesions, histomorphometric alteration and improved the immune-staining of the pro-fibrotic (TGF-β1), pro-apoptotic (caspase-3 and Bax), and anti-apoptotic (Bcl-2) proteins in cardiac tissues. Collectively, pre-coadministration of DPPE partially mitigated DOX-induced cardiac injuries via its antioxidant, anti-inflammatory, anti-fibrotic, and anti-apoptotic potential.

Abstract
Autophagy is a basic physiological process maintaining cell renewal, the degradation of dysfunctional organelles, and the clearance of abnormal proteins and has recently been identified as a main mechanism underlying the onset and progression of Alzheimer's disease (AD). The APOE ɛ4 genotype is the strongest genetic determinant of AD pathogenesis and initiates autophagic flux at different times. This review synthesizes the current knowledge about the potential pathogenic effects of ApoE4 on autophagy and describes its associations with the biological hallmarks of autophagy and AD from a novel perspective. Via a remarkable variety of widely accepted signaling pathway markers, such as mTOR, TFEB, SIRT1, LC3, p62, LAMP1, LAMP2, CTSD, Rabs, and V-ATPase, ApoE isoforms differentially modulate autophagy initiation; membrane expansion, recruitment, and enclosure; autophagosome and lysosome fusion; and lysosomal degradation. Although the precise pathogenic mechanism varies for different genes and proteins, the dysregulation of autophagic flux is a key mechanism on which multiple pathogenic processes converge.

Abstract
Objectives: To evaluate the effect of Yugengtongyu granules on reducing the incidence of adverse cardiovascular events and improving quality of life (QOL) in patients with stable coronary artery disease (SCAD). Methods: A double-blind randomized controlled trial was conducted among SCAD population. One hundred fourteen patients were randomly assigned to experimental group (n = 57) and control group (n = 57) following randomized block design. Combined with the basis of standard treatment of SCAD, the experimental group and control group received Yugengtongyu granules or placebo, respectively, twice daily for 6 months and were followed for another 1 year (18 months in total from enrollment). Major outcomes (any occurrence of cardiovascular death, nonfatal myocardial infarction, or coronary revascularization), minor outcomes (any occurrence of all-cause death, ischemic stroke, readmission due to unstable angina, heart failure, or malignant arrhythmia), and composite outcomes (union of major and minor outcomes) were used to evaluate prognosis; Seattle Angina Questionnaire (SAQ) was applied to evaluate QOL, and levels of low density lipoprotein-cholesterol (LDL-C) and high sensitive C reacting protein (HS-CRP) in serum were tested. Results: The incidence of composite outcomes in the experimental group was significantly lower than that in the control group (3 [5.2%] vs. 11 [19.2%], hazard ratio: 0.273, 95% confidence interval: 0.080-0.926, p = 0.022); major outcomes, minor outcomes, and independent events such as nonfatal myocardial infarction showed lowering trend in experimental group. Experimental group scored significantly higher than control group in four dimensions of SAQ: physical limitation, angina frequency, treatment satisfaction, and disease perception at the third- and sixth-month follow-up; there was no significant difference in serum level of LDL or HS-CRP at all scheduled timepoints. Conclusion: The addition of Yugengtongyu granules based on current standard treatment reduced the incidence of composite outcomes and improved QOL in patients with SCAD. The trial was registered in the Chinese Clinical Trial Registry (ChiCTR-TRC-13004370).
