[PMID: 39237965 PMCID: PMC11376054 DOI: 10.1186/s42826-024-00218-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2024] [Revised: 08/07/2024] [Accepted: 08/30/2024] [Indexed: 09/07/2024] Open
Abstract
Ischemic heart disease is the most prevalent cause of death worldwide affecting both the gender of all age groups. The high mortality rate is due to damage of myocardial tissue that emanates at the time of myocardial ischemia and re-oxygenation, thus averting reperfusion injury is recognized as a potential way to reduce acute cardiac injury and subsequent mortality. Flavonoids are polyphenol derivatives of plant origin and empirical shreds of evidence substantiate their numerous activities such as antioxidant, anti-inflammatory, anti-apoptotic, and anti-thrombotic activity, leading to their role in cardio protection. Recent investigations have unveiled the capacity of flavonoids to impede pivotal regulatory enzymes, signaling molecules, and transcription factors that orchestrate the mediators participating in the inflammatory cascade. The present comprehensive review, dwells on the preclinical studies on the effectiveness of flavonoids from the year 2007 to 2023, for the prevention and therapeutics for myocardial ischemia-reperfusion injury.

In vitro and in vivo evaluation of antibacterial activity and mechanism of luteolin from Humulus scandens against Escherichia coli from chicken. Poult Sci 2024; 103:104132. [PMID: 39208485 PMCID: PMC11399789 DOI: 10.1016/j.psj.2024.104132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 07/08/2024] [Accepted: 07/24/2024] [Indexed: 09/04/2024] Open
Abstract
Resistance of Escherichia coli (E.coli) to antibiotics has steadily increased over time; hence, there is an urgent need to develop safer alternatives to antibiotics. The present study aimed to evaluate the effect of luteolin (Lut) on E. coli from chicken. The bioactive compound Lut from Humulus scandens was selected by network pharmacology and molecular docking analyses. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and confocal laser scanning microscopy (CLSM) were used to observe the effects of Lut on the morphology and structure of E. coli cells. The data-independent acquisition (DIA) method was used to analyze protein expression level of E. coli before and after Lut treatment. The in vivo evaluation of the antibacterial, anti-inflammatory, and oxidative effects of Lut on E.coli was conducted using E.coli isolated strains infected the SPF chicken model. The network pharmacology analysis revealed 19 distinctive bioactive compounds such as Lut and β-sitosterol in H. scandens; furthermore, 30 core targets were selected from H. scandens. The KEGG enrichment analysis showed that the PI3K-Akt, TNF, MAPK, IL-17, JAK-STAT, and HIF-1 pathways were related from H. scandens. Based on the results of the network pharmacology analysis, Lut was subjected to screening by molecular docking analysis to determine its antibacterial effect on E. coli and the associated mechanism of action. The minimum inhibitory concentration (MIC) of Lut against E. coli standard strains was 500 µg/mL. SEM, TEM, and CLSM results indicated that Lut damaged the cell wall and cell membrane of E. coli strains and destroyed the cell structure, leading to cell death.The expression level of membrane structure, Phenylalanine metabolism and some other metabolic pathways in E.coli changed after treatment with Lut (P < 0.05). In vivo experiments in the SPF chicken model showed that Lut treatment alleviated the decline in the growth performance of chickens (P < 0.05), prevented pathological changes in the correspond ding organs and suppressed the inflammatory response induced by E. coli infection (P < 0.05), improved the immunity and antioxidant capacity of chickens (P < 0.05), and protected them against infection with E. coli strains. To summarize, Lut from H. scandens can inhibit E. coli growth by damaging the cell membrane structureand affecting the expression level of some metabolic proteins. In vivo experiments also showed that Lut can significantly reduce the damage caused by E. coli isolates on SPF chickens, improve their antioxidant capacity and immunity, and reduce inflammatory responses following E. coli infection.

Lipids Health Dis 2024; 23:51. [PMID: 38368320 PMCID: PMC10874037 DOI: 10.1186/s12944-024-02028-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Accepted: 01/22/2024] [Indexed: 02/19/2024] Open
Abstract
BACKGROUND Myocardial ischemia-reperfusion injury (MIRI) is widespread in the treatment of ischemic heart disease, and its treatment options are currently limited. Adiponectin (APN) is an adipocytokine with cardioprotective properties; however, the mechanisms of APN in MIRI are unclear. Therefore, based on preclinical (animal model) evidence, the cardioprotective effects of APN and the underlying mechanisms were explored. METHODS The literature was searched for the protective effect of APN on MIRI in six databases until 16 November 2023, and data were extracted according to selection criteria. The outcomes were the size of the myocardial necrosis area and hemodynamics. Markers of oxidation, apoptosis, and inflammation were secondary outcome indicators. The quality evaluation was performed using the animal study evaluation scale recommended by the Systematic Review Center for Laboratory animal Experimentation statement. Stata/MP 14.0 software was used for the summary analysis. RESULTS In total, 20 papers with 426 animals were included in this study. The pooled analysis revealed that APN significantly reduced myocardial infarct size [weighted mean difference (WMD) = 16.67 (95% confidence interval (CI) = 13.18 to 20.16, P < 0.001)] and improved hemodynamics compared to the MIRI group [Left ventricular end-diastolic pressure: WMD = 5.96 (95% CI = 4.23 to 7.70, P < 0.001); + dP/dtmax: WMD = 1393.59 (95% CI = 972.57 to 1814.60, P < 0.001); -dP/dtmax: WMD = 850.06 (95% CI = 541.22 to 1158.90, P < 0.001); Left ventricular ejection fraction: WMD = 9.96 (95% CI = 7.29 to 12.63, P < 0.001)]. Apoptosis indicators [caspase-3: standardized mean difference (SMD) = 3.86 (95% CI = 2.97 to 4.76, P < 0.001); TUNEL-positive cells: WMD = 13.10 (95% CI = 8.15 to 18.05, P < 0.001)], inflammatory factor levels [TNF-α: SMD = 4.23 (95% CI = 2.48 to 5.98, P < 0.001)], oxidative stress indicators [Superoxide production: SMD = 4.53 (95% CI = 2.39 to 6.67, P < 0.001)], and lactate dehydrogenase levels [SMD = 2.82 (95% CI = 1.60 to 4.04, P < 0.001)] were significantly reduced. However, the superoxide dismutase content was significantly increased [SMD = 1.91 (95% CI = 1.17 to 2.65, P < 0.001)]. CONCLUSION APN protects against MIRI via anti-inflammatory, antiapoptotic, and antioxidant effects, and this effect is achieved by activating different signaling pathways.

Abstract
Acute myocardial infarction remains the leading cause of death in humans. Timely restoration of blood perfusion to ischemic myocardium remains the most effective strategy in the treatment of acute myocardial infarction, which can significantly reduce morbidity and mortality. However, after restoration of blood flow and reperfusion, myocardial injury will aggravate and induce apoptosis of cardiomyocytes, a process called myocardial ischemia-reperfusion injury. Studies have shown that the loss and death of cardiomyocytes caused by oxidative stress, iron load, increased lipid peroxidation, inflammation and mitochondrial dysfunction, etc., are involved in myocardial ischemia-reperfusion injury. In recent years, with the in-depth research on the pathology of myocardial ischemia-reperfusion injury, people have gradually realized that there is a new form of cell death in the pathological process of myocardial ischemia-reperfusion injury, namely ferroptosis. A number of studies have found that in the myocardial tissue of patients with acute myocardial infarction, there are pathological changes closely related to ferroptosis, such as iron metabolism disorder, lipid peroxidation, and increased reactive oxygen species free radicals. Natural plant products such as resveratrol, baicalin, cyanidin-3-O-glucoside, naringenin, and astragaloside IV can also exert therapeutic effects by correcting the imbalance of these ferroptosis-related factors and expression levels. Combining with our previous studies, this review summarizes the regulatory mechanism of natural plant products intervening ferroptosis in myocardial ischemia-reperfusion injury in recent years, in order to provide reference information for the development of targeted ferroptosis inhibitor drugs for the treatment of cardiovascular diseases.

Abstract
N6-methyladenosine (m6A) is emerging as an essential regulator in the progression of myocardial ischemia reperfusion (I/R) injury. However, the in-depth functions and mechanisms for m6A are still unclear. This work aimed to explore the potential functions and mechanisms for myocardial I/R injury. In this study, m6A methyltransferase WTAP and m6A modification level elevated in the hypoxia/reoxygenation (H/R) induced rat cardiomyocytes (H9C2) and I/R injury rat model. Bio-functional cellular experiments demonstrated that knockdown of WTAP remarkably released the proliferation and reduced the apoptosis and inflammatory cytokines induced by H/R. Moreover, exercise training alleviated WTAP level in exercise-trained rats. Mechanistically, methylated RNA immunoprecipitation sequencing (MeRIP-Seq) revealed that a remarkable m6A modification site was found in the 3'-UTR of FOXO3a mRNA. Moreover, WTAP triggered the installation of m6A modification on FOXO3a mRNA through m6A reader YTHDF1, thereby enhancing the stability of FOXO3a mRNA. Collectively, WTAP/YTHDF1/m6A/FOXO3a axis regulates the myocardial I/R injury progression, which provides new insights for the treatment of myocardial injury.

Abstract
Luteolin and naringenin are flavonoids found in various foods/beverages and present in certain dietary supplements. After a high intake of these flavonoids, their sulfate and glucuronide conjugates reach micromolar concentrations in the bloodstream. Some pharmacokinetic interactions of luteolin and naringenin have been investigated in previous studies; however, only limited data are available in regard to their metabolites. In this study, we aimed to investigate the interactions of the sulfate and glucuronic acid conjugates of luteolin and naringenin with human serum albumin, cytochrome P450 (CYP2C9, 2C19, and 3A4) enzymes, and organic anion transporting polypeptide (OATP1B1 and OATP2B1) transporters. Our main findings are as follows: (1) Sulfate conjugates formed more stable complexes with albumin than the parent flavonoids. (2) Luteolin and naringenin conjugates showed no or only weak inhibitory action on the CYP enzymes examined. (3) Certain conjugates of luteolin and naringenin are potent inhibitors of OATP1B1 and/or OATP2B1 enzymes. (4) Conjugated metabolites of luteolin and naringenin may play an important role in the pharmacokinetic interactions of these flavonoids.

Abstract
How to prevent cerebral ischemia-reperfusion injury (CI/R) is critical for treating ischemic stroke. LncRNA SNHG11 can participate in several diseases by competing endogenous RNA (ceRNA), but its’ role in CI/R is unclear. Hypoxia/reoxygenation model (H/R group) cells were set
and separated into control team; H/R team; H/R+SNHG11 team and H/R+si-SNHG11 team followed by analysis of LncRNA SNHG11 by real-time PCR, LncRNA SNHG11 subcellular distribution by FISH assay, MTT assay for cell proliferation, flow cytometry for apoptosis, ROS and LDH content and PTEN expression
by Western blot. In H/R group, SNHG11 level significantly increased and cell proliferation significantly decreased, along with increased cell apoptosis, ROS activity, LDH content and PTEN expression in comparison of control group (P-value less than 0.05); The foregoing variation was
promoted further by the H/R group after overexpression of SNHG11 (P-value below 0.05) and reversed after transfection of SNHG1 siRNA (P <0.05). LncRNA SNHG11 is mainly localized on the cell membrane. miR-16 is a SNHG11 targeted miRNA. Transfection of miR-16 mimics into PC12
cells in H/R group can significantly promote cell proliferation, inhibit apoptosis, reduce ROS activity, LDH content and PTEN expression versus the H/R group (P-value less than 0.05). SNHG11 level in H/R condition is increased and might target miR-16 to regulate PTEN expression and
oxidative stress, leading to apoptosis and damage.
