Molecular Mechanisms of Luteolin Induced Growth Inhibition and Apoptosis of Human Osteosarcoma Cells
Luteolin is a flavone in medicinal plants as well as some vegetables and spices. It is a natural anti-oxidant with less pro-oxidant potential but apparently with a better safety profile. The purpose of this study was to investigate the molecular mechanism of luteolin-mediated apoptosis of MG-63 human osteosarcoma cells. MTT assay kit was employed to evaluate the effects of luteolin on MG-63 cel...
Infection/inflammation is commonly associated with preterm birth (PTB), initiating uterine contractions and rupture of fetal membranes. Proinflammatory cytokines induce matrix metalloproteinases (MMPs) that degrade the extracellular matrix (ECM) and prostaglandins which initiate uterine contractions. Nuclear factor-κB (NF-κB) and activator-protein- (AP-)1 have key roles in the formation of thes...
Flavonoids, a class of natural polyphenolic compounds, inhibit cell cycle progression and induce apoptosis. This study was performed to investigate the antiproliferative effect of luteolin, the flavonoid isolated from Ixeris sonchifolia Hance, and to elucidate the detailed apoptotic mechanism in HCC cells. According to the result of MTT assay luteolin possessed antiproliferative effect, and Hep...
Aromatase inhibitors (AIs) have been used as adjuvant therapeutic agents for breast cancer. Their adverse side effect on blood lipid is well documented. Some natural compounds have been shown to be potential AIs. In the present study, we compared the efficacy of the flavonoid luteolin to the clinically approved AI letrozole (Femara; Novartis Pharmaceuticals, East Hanover, NJ) in a cell and a mo...
Luteolin 7-O-glucuronide, luteolin 7-O-glucurono-(1-->6)-glucoside, apigenin 7-O-glucuronide as well as free aglycones luteolin and apigenin have been isolated from lemon catnip herb (Nepeta cataria L. var citriodora). Luteolin 7-O-glucurono-(1-->6)-glucoside is probably a new compound, for the first time described. Two minor constituents of flavonoid fraction have been identified as apigenin 7...
High blood cholesterol has been associated with cardiovascular diseases. The enzyme HMG CoA reductase (HMGCR) is responsible for cholesterol synthesis, and inhibitors of this enzyme (statins) have been used clinically to control blood cholesterol. Sterol regulatory element binding protein (SREBP) -2 is a key transcription factor in cholesterol metabolism, and HMGCR is a target gene of SREBP-2. ...
Oral squamous cell carcinoma is the most common malignancy of the oral cavity, and treatment approaches are inadequate. Luteolin, a natural flavonoid compound, has been shown to have anti-tumorigenic properties on various types of tumors. Therefore, we hypothesized that luteolin has anti-tumorigenic properties for oral squamous cell carcinoma, and may provide effective chemotherapy. Results rev...
Two lactoylate flavonoids, luteolin-7-lactate and luteolin-7-glucosyl-lactate were isolated from Ballota nigra. They should be used for the chemical standardization of this drug of medicinal interest.
