lycopene/hypoxia

OBJECTIVE To investigate the effects of lycopene on primary cultured neonatal mouse cardiomyocytes with hypoxia/reoxgenation (H/R) injury and explore related mechanism. METHODS Primary cultured neonatal mouse cardiomyocytes were randomly divided to control group (control); lycopene group (5 μmol/L,

OBJECTIVE To investigate the possible mechanism of lycopene on protecting against hypoxia/reoxygenation (H/R)-injury. METHODS Primary cultured cardiomyocytes, isolated from neonatal mouse, were divided into three groups randomly: control group (C) ; H/R group(4 h H followed by 8 h R); lycopene+H/R

[Figure: see text] Lycopene (lyc) has an effect on preventing cancer, yet its effects on hypoxia/reoxygenation (H/R) injury remained obscure. The study aimed at discovering its role in preventing hepatic cells against H/R injury. Hepatic cells were incubated in hypoxia incubator to simulate

Nowadays, drugs protecting ischemia/reperfusion (I/R) myocardium become more suitable for clinic. It has been confirmed lycopene has various protections, but lacking the observation of its effect on endoplasmic reticulum stress (ERS)-mediated apoptosis caused by hypoxia/reoxygenation (H/R). This

Endoplasmic reticulum (ER) stress induced apoptosis plays a pivotal role in myocardial ischemia/reperfusion (I/R)-injury. Inhibiting ER stress is a major therapeutic target/strategy in treating cardiovascular diseases. Our previous studies revealed that lycopene exhibits great pharmacological

Lycopene (Ly), the most common type of antioxidant in the majority of diet types, provides tolerance to ischemia/reperfusion injury. However, the underlying mechanism of the protective effects observed following Ly administration remains poorly investigated. The aim of the current study was to

Targeting altered pathways during initial stage of hepatocellular carcinoma (HCC) development is viewed as an effective and promising strategy to control this disease. Present study investigated the potential effect of lycopene-enriched tomato extract (LycT) on hypoxia-induced factor (HIF)-1α, HOX,

BACKGROUND Hypoxia/reoxygenation(H/R)-induced apoptosis of cardiomyocytes plays an important role in myocardial injury. Lycopene is a potent antioxidant carotenoid that has been shown to have protective properties on cardiovascular system. The aim of the present study is to investigate the potential

In a previous study, the neuroprotection provided by some hindered phenols of synthetic nature and alpha-tocopherol in guinea-pig detrusor strips subjected to ischaemia/reperfusion-like conditions was shown to be related directly to the antioxidant activity. The aim of the present study was to

OBJECTIVE Bone marrow mesenchymal stem cells (MSCs) have been identified to have the potential to differentiate into multiple types of cells. And the therapy based on transplantation of MSCs in some solid organs has been suggested in recent years. However, the rejection reaction often occurs in the

BACKGROUND Oral uptake of lycopene has been shown to be beneficial for preventing myocardial ischemia-reperfusion (I/R) injury. However, the strong first-pass metabolism of lycopene influences its bioavailability and impedes its clinic application. In this study, we determined an intravenous (IV)

Di-(2-ethylhexyl) phthalate (DEHP) is a widespread pollutant that badly affects animals and human health. Lycopene (LYC) has been used as a dietary supplement that has effective antioxidant and anti-obesity functions. The present goal was to understand the molecular mechanisms of LYC preventing

OBJECTIVE To investigate the effect of lycopene extracted from tomatoes (LycT) on ultrastructure, glycolytic enzymes, cell proliferation markers and hypoxia during N-Nitrosodiethylamine (NDEA)-induced hepatocarcinogenesis. METHODS Female BALB/c mice were randomly divided into four groups: The

OBJECTIVE Renal ischemia-reperfusion injury may occur due to nephron-sparing surgery in patients with a solitary kidney or restricted renal parenchymas. Prophylactic agents do not always achieve their intended effects and may exhibit side effects. The present study was designed to investigate the

In photosynthetic organisms, carotenoids serve essential roles in photosynthesis and photoprotection. A previous report designated CruP as a secondary lycopene cyclase involved in carotenoid biosynthesis [Maresca J, et al. (2007) Proc Natl Acad Sci USA 104:11784-11789]. However, we found that cruP
