In the present study, we investigated whether apigenin significantly affects tumor necrosis factor-α (TNF-α)-induced production and gene expression of MUC5AC mucin in airway epithelial cells. Confluent NCI-H292 cells were pretreated with apigenin for 30 min and then stimulated with TNF-α for 24 h or
OBJECTIVE
Development of androgen independence and resistance to apoptosis in prostate cancer are often correlated with high levels of serum tumor necrosis factor (TNF)-alpha in these patients. The loss of sensitivity to TNF-alpha-induced apoptosis in androgen-insensitive prostate carcinoma cells is
Diabetes mellitus is associated with increased endothelial dysfunction and development of atherosclerotic vascular diseases. In contrast, an increased intake of dietary flavonoids is associated with a decreased risk of cardiovascular diseases. Here we demonstrate that high glucose (HG) and tumor
Although hyperglycemia can induce diabetic vascular disorders, the mechanisms responsible for the early stages of this process are unknown. To determine the factor(s) that initially stimulate hyperglycemia and the preventive effects of polyphenols, we examined the effects of high glucose (HG)
OBJECTIVE
Apigenin is a flavonoid that effectively blocks intercellular adhesion molecule-1 (ICAM-1) upregulation and leukocyte adhesion in response to cytokines in vitro. In the present study, we characterized the effects of tumor necrosis factor (TNF) on ICAM-1 expression in different tissues of
Expression level of Tumor Necrosis Factor-related apoptosis-inducing ligand (TRAIL) receptors is one of the most important factors of TRAIL-mediated apoptosis in cancer cells. We here report for the first time data concerning TRAIL-R1 and TRAIL-R2 receptor expression on RAW264.7 macrophages. Three
Activated rheumatoid arthritis (RA) fibroblast-like synoviocytes (RAFLSs) play a central role in both initiating and driving RA. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has been documented to induce apoptosis only in a small proportion of RAFLSs, which is followed by an
Dietary flavonoid apigenin is expected to have preventive and therapeutic potential against malignant tumors. In this report, we show for the first time that apigenin markedly induces the expression of death receptor 5 (DR5) and synergistically acts with exogenous soluble recombinant human tumor
Apigenin suppressed tumor necrosis factor α-induced cell proliferation and prostaglandin E2 expression via the attenuation of nuclear factor κB pathway in endometriotic stromal cells in vitro. Apigenin reduced the mitogenic activity and inflammatory reaction in endometriotic stromal cells.
Flavonoids have been reported to bring benefits in lowering inflammation, oxidative stress and exert positive effects in cancer and cardiovascular and chronic inflammatory diseases. Apigenin, kaempferol and resveratrol present in fruits, vegetables and grain were investigated for their effect on the
BACKGROUND
Apigenin, a natural plant flavone, may have chemopreventive and therapeutic potentials for anti-inflammatory, antioxidant, and anti-cancer. Nevertheless, the anti-tumor effect of apigenin on human head and neck squamous cell carcinoma (HNSCC) is not fully understood.
METHODS
The
Many plant-derived substances have estrogenic activities. Due to their ability to bind the estrogen receptor, these compounds have the potential to counteract the deleterious effects of estrogen deficiency on bone. In this study, the effects of apigenin on the function of osteoblastic MC3T3-E1 cells
BACKGROUND Intervertebral disc degeneration (IDD) is a common spinal disease affected by environmental and lifestyle factors that has a significant pathological cascade toward inflammation and partial disability. There is currently no therapy that can completely restore the cellular derangement in
Polyphenols such as apigenin, kaempferol or resveratrol are typically found in plants, including fruits, vegetables, herbs and spices, which have a wide range of biological functions such as antioxidative, anti-inflammatory, vasodilative, anticoagulative and proapoptotic. Discovering such
The effects of some selected flavonoids on tumor necrosis factor-alpha (TNF)-induced cytotoxicity in murine fibroblast L-929 cells were studied. All of the flavanones tested as well as a flavan, epicatechin, protected L-929 cells from TNF-induced cell death of the flavanones tested, hesperetin,
