Molecular insight of miRNA-217 role in the pathogenesis of myocardial infarction: Promising diagnostic biomarker and therapeutic target

Article

作者: Zaafan, Mai A ; Zaafan, Mai A. ; Abdelhamid, Amr M. ; Abdelhamid, Amr M

BackgroundGlobally, myocardial infarction (MI) is one of the main causes of death. This study aims to investigate the role of miR-217 in the pathogenesis through targeting MAPK and PI3K/AKT signaling pathways in experimental model of myocardial infarction and studying the possible cardioprotective role of dihydromyricetin (DHM) through modulation of this pathway.MethodsDihydromyricetin was injected (100 mg/kg; p.o.) in isoprenaline induced myocardial infarction rat model for 14 days. Rats were anaesthetized and blood samples were taken for serum separation, estimation of creatine kinase-MB (CK-MB), and troponin-I levels after 24 h had passed since the last isoprenaline injection. In addition, the hearts were also used for the other biochemical studies and the histological evaluation.ResultsDHM resulted in a significant suppression of the elevated levels miR-217 and MAPK compared to the MI control group and restored the normal level of serum CK-MB. Furthermore, DHM successfully restored the oxidative balance and halted the pro-inflammatory mediators in the cardiac tissue.ConclusionAccordingly, our experiment emphasizes the anti-ischemic property that has been demonstrated through modulation of expression level of miR-217 and consequent deactivation of MAPK and PI3K/AKT signaling pathways, and this was assured by halting downstream pro-inflammatory markers.

Natural α-glucosidase inhibitors from Aquilaria sinensis leaf-tea: Targeted bio-affinity screening, identification, and inhibition mechanism

Article

作者: Fei, Tao ; Lin, Xue ; Liu, Yingxin ; Wang, Lu ; Li, Fangliang ; Liu, Zhonghua

Aquilaria sinensis leaves have long been consumed as a popular replacement tea for lowering postprandial blood glucose levels, but their specific functional components remain unclear. In this study, Aquilaria sinensis leaf-tea 70 % ethanol extract (ALTE) exhibited excellent anti-α-glucosidase activity (IC₅₀ = 6.93 ± 1.91 μg/mL) and promoted glucose consumption ability in 3 T3-L1 preadipocyte cells. Subsequently phenolic compositions of ALTE were identified for the first time. After that, five potential α-glucosidase inhibitors (α-GIs) including cynaroside-3,5-diglucose, malvidin 3-glucose, epicatechin, epigallocatechin gallate, and dihydromyricetin in ALTE were screened using a targeted bio-affinity ultrafiltration-HPLC/MS method. Moreover, these five α-GIs all showed good anti-α-glucosidase effects and glucose consumption-promoting ability. Furthermore, the binding properties and inhibition mechanisms of five α-GIs to α-glucosidase were further analyzed via enzyme inhibition kinetics, molecular docking, and molecular dynamics simulation. This study confirms that Aquilaria sinensis leaf-tea is effective in preventing post-hyperglycemia in vitro models, suggesting potential for future research in human trials.

An oxidising and substituting one-pot reaction strategy has been developed to synthesise dihydromyricetin derivatives with the aim of enhancing the inhibitory activity of dihydromyricetin against SARS-CoV-2. Different ω-methoxy-ω-oxeylkyl was introduced in C₇-OH site and yielded eight analogs, all of them showed good inhibitory activity against SARS-CoV-2 3CL^pro with IC₅₀ values ranging from 0.72 to 2.36 μM. In the Vero E6-cell, compound 3 has a good activity of anti-SARS-CoV-2 virus (Omicron virus BA.5) in the prevention model, with an EC₅₀ of 15.84 μM, and so do compound 10 in the therapeutic model, with an EC₅₀ of 11.52 μM. The results suggest that the introduction of long chain ω-oxeylkyl at C₇-OH facilitate the inhibition of viral replication in the therapeutic model, which is consistent with the binding energies predicted from molecular docking conclusions. It implies that dihydromyricetin derivatives have the potential to become effective inhibitors of SARS-CoV-2 Omicron and other viruses.

Three Journal of Pharmaceutical Analysis Studies Explore the Use of Traditional Chinese Medicine for Various Diseases

XI'AN, China, Jan. 26, 2024 /PRNewswire/ -- Despite demonstrating significant clinical efficacy against various diseases, the widespread use of Traditional Chinese Medicine (TCM) is still limited. This is mainly due to the complexity in their formulation and lack of sufficient pharmacological and safety-related data. To address this gap, a new issue of the Journal of Pharmaceutical Analysis presents three independent studies which assessed the potency of TCM-based compounds for various human diseases, along with their molecular mechanisms of action. Continue Reading Latest research unveils the potential of Traditional Chinese Medicine compounds for the treatment of human diseases The accumulation of excess fat in the liver leads to non-alcoholic fatty liver disease (NAFLD). Oridonin (ORI), a TCM derived from the Chinese herb Rabdosia rubescens, exhibits anti-inflammatory effects. An article available online on 21 August 2023 and published in Volume 13, Issue 11 of the journal in November 2023, now reveals that ORI regulates lipid homeostasis in the liver by maintaining the balance between triglyceride (TG) and phosphatidylethanolamine (PE), through modulation of adipose triglyceride lipase (ATGL) and ethanolamine phosphotransferase 1 (EPT1) expression via the liver X receptor alpha (LXRα) signaling pathway. "When the TG-PE lipid balance is disturbed, the seesaw tilts towards TG, increasing the risk of NAFLD. Restoring lipid homeostasis using compounds like oridonin can alleviate lipid accumulation and liver cytotoxicity," explains Professor Lan Tang. Tumor heterogeneity compromises the efficacy of radiotherapy for treating lung cancer. Radiosensitizers help prime tumor cells and improve their response to radiation. Now, in an article available online on 7 June 2023 and published in Volume 13, Issue 11 of the journal in November 2023, researchers found that ginsenoside Rg5 induced cell-cycle arrest and enhanced radiation-induced cell death. Ginsenoside Rg5 interacts with heat shock protein alpha (HSP90α) with high affinity and reduces the binding between HSP90 and cell division cycle 37 (CDC37), promoting HSP90-CDC37 client protein degradation. "Ginsenoside Rg5 can be potentially developed into a new drug for improving the sensitivity of lung cancer and other types of tumors to radiation therapy," the authors explain. Diabetic retinopathy (DR) is characterized by the activation of oxidative stress pathways in response to high glucose. In a study available online on 12 May 2023 and published in Volume 13, Issue 11 of the journal in November 2023, researchers synthesized a polymeric drug complex by combining a natural flavonoid antioxidant known as dihydromyricetin (DMY) with iron (Fe) ions in nano-coordinated polymer particles (NCPs). Fe-DMY NCPs can alleviate glucose-induced oxidative damage and reverse the pathological features of DR by decreasing the expression of key proteins involved in microvascular dysfunction. Fe-DMY NCPs could also inhibit the activation of Poldip2-Nox4-H2O2 signaling pathway and down-regulate important vascular function indicators such as VCAM-1, HIF-1α, and VEGF. Explaining its applications, the authors say, "We report for the first time the synthesis and validation of ultra-small Fe-DMY NCPs. Fe-DMY complexes bear the potential to alleviate the impact of DR on vision, thus improving the quality of life of affected individuals." These studies provide a scientific basis for the development of TCM-based compounds into effective targeted therapies for various diseases.
