The tea catechin epigallocatechin gallate inhibits NF-κB-mediated transcriptional activation by covalent modification.

Potential health benefits of consuming tea are thought to include anti-inflammatory actions of its constituent flavonoids including catechins, which are well-recognized antioxidants. We analyzed and discovered a novel mechanism by which epigallocatechin gallate (EGCG), the most abundant polyphenol in tea and a putative health-promoting constituent, inhibits activation of the nuclear transcription factor NF-κB, which mediates inflammatory responses to cytokines and other agents. We found that EGCG inhibits NF-κB-p65 transcriptional activity, by preventing NF-κB-p65 binding to κBs in normal human bronchial epithelial cells.

Epigallocatechin gallate diminishes cigarette smoke-induced oxidative stress, lipid peroxidation, and inflammation in human bronchial epithelial cells.

Cigarette smoke (CS), the major risk factor of chronic obstructive pulmonary disease (COPD), contains numerous free radicals that can cause oxidative stress and exaggerated inflammatory responses in the respiratory system. Lipid peroxidation which is oxidative degradation of polyunsaturated fatty acids and results in cell damage has also been associated with COPD pathogenesis. Increased levels of lipid peroxidation as well as its end product 4-hydroxynonenal have indeed been detected in COPD patients.

Epigallocatechin gallate suppresses inflammation in human coronary artery endothelial cells by inhibiting NF-κB.

The endothelium is a critical regulator of vascular homeostasis, controlling vascular tone and permeability as well as interactions of leukocytes and platelets with blood vessel walls. Consequently, endothelial dysfunction featuring inflammation and reduced vasodilation are considered central to cardiovascular disease (CVD) pathogenesis and have become a therapeutic area of focus. Type II endothelial cell (EC) activation by stress-related stimuli such as tumor necrosis factor-α (TNF-α) initiates the nuclear factor-κB (NF-κB) signaling pathway, a master regulator of inflammatory responses.

Combined cardio-protective ability of syringic acid and resveratrol against isoproterenol induced cardio-toxicity in rats via attenuating NF-kB and TNF-α pathways.

The study was conducted to evaluate the cardio-protective activity of combination (COMB) of syringic acid (SA) and resveratrol (RV) against isoproterenol (ISO) induced cardio-toxicity in rats. Rats were pre-treated orally with SA (50 mg/kg), RV (50 mg/kg) and combination of SA (25 mg/kg) and RV (25 mg/kg) along with positive control gallic acid (50 mg/kg) for 30 days. The effects of ISO on cardiac markers, lipid profile and lipid peroxidation marker, anti-oxidant enzymes and m-RNA expression of nuclear factor-kappa B (NF-kB) and tumor necrosis factor-α (TNF-α) were observed along with histopathological observations of simple and transmission electron microscopes (TEM).

Protective effects of syringic acid, resveratrol and their combination against isoprenaline administered cardiotoxicity in wistar rats.

Objective: To evaluate the cardio-protection of syringic acid (SA) in combination with resveratrol (RV) in isoproterenol (ISO) induced myocardial infarcted (MI) rats.

Methods: Groups of all rats were subjected oral pre-treatment at the beginning of the study with SA (50 mg/kg), RV (50 mg/kg) and combination (COMB) of SA (25 mg/kg) and RV (25 mg/kg) along with gallic acid (GA) (50 mg/kg) for 30 days. After sacrification, homogenate of heart tissue along with serum were utilized for further biochemical investigations.

fruit ethanolic extract ameliorates lipids, lipoproteins, lipid metabolism marker enzymes and paraoxonase in isoproterenol-induced myocardial infarcted rats.

The present study aimed to evaluate the effect of fruit ethanolic extract (TpFE) on lipids, lipoproteins, lipid metabolism marker enzymes and paraoxonase (PON) in isoproterenol (ISO)-induced myocardial infarcted rats. PON is an excellent serum antioxidant enzyme which involves in the protection of low density lipoprotein cholesterol (LDL-C) from the process of oxidation for the prevention of cardiovascular diseases. ISO caused a significant increase in the concentration of total cholesterol, triglycerides, LDL-C, very low density lipoprotein cholesterol and lipid peroxidation whereas significant decrease in the concentration of high density lipoprotein cholesterol.

Molecular assessment of protective effect of Vitex negundo in ISO induced myocardial infarction in rats.

Myocardial infarction (MI) is the one of the major causes of death worldwide, however the molecular mechanisms hidden under this disease conditions remain unknown. This demands serious attention to unravel the molecular mechanisms to identify the therapeutic strategies either to prevent or to control MI. Ayurveda is becoming one of the best alternatives for the modern medicines.

In vivo and molecular docking studies using whole extract and phytocompounds of Aegle marmelos fruit protective effects against Isoproterenol-induced Myocardial infarction in rats.

Myocardial infarction (MI) is a leading major health problem with increased morbidity and mortality worldwide. The present study investigates isoproterenol (ISO) induced MI and the beneficial role of Aegle marmelos fruit extract (AMFE) in rats. Our results indicated the significant augmentation of plasma nitric oxide (NOx) levels, C-reactive protein (CRP), homocysteine, apolipoprotein B (apo-B), cardiac tissue lipid peroxidation and liver 3-hydroxy-3 methyl glutaryl CoA (HMG-CoA) reductase activity in ISO treated rats (85mg/kg b.

Nutraceutical inherent of Spinacia oleracea Linn. methanolic leaf extract ameliorates isoproterenol induced myocardial necrosis in male albino Wistar rats via mitigating inflammation.

Cardiovascular diseases (CVDs) remain the principal cause of death in both developed and developing countries. The present study was intended to appraise the nutraceutical inherent of HPLC standardized Spinacia oleracea methanolic leaf extract (SoLE) in isoproterenol (ISO) induced male albino Wistar rats via activation of pro-inflammatory signaling pathway that drives myocardial necrosis. Biochemical analysis of ISO injected rats showed significant alterations in the activities of homocysteine, paraoxonase, lecithin cholesterol acyltransferase, C-reactive protein, myeloperoxidase and caspase-3 which were further confirmed by the histopathological examination.

Cardioprotective effect of Vitex negundo on isoproterenol-induced myocardial necrosis in wistar rats: A dual approach study.

Cardiovascular diseases (CVDs) are becoming the major cause of deaths worldwide, and their treatment demands novel therapeutic strategies. In this connection, we have identified p21 activated kinase 1 (PAK1) as a novel therapeutic target for the treatment of myocardial infarction (MI), where its expression is decreased when MI is induced with isoproterenol (ISO), which was brought back normal with pretreatment of Vitex negundo leaf ethanolic extract (VNE). These results were also supported by histopathological studies, cardiac markers, antioxidants, and inflammatory cytokines (NF-κB and IL-1β).
