[Effect of beta-ionone in human mammary cancer cells (Er-) by MAPK pathway].

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To investigate the effect of cell proliferation in human breast cancer cells (MDA-MB 435), which has non-receptor of estrogen (Er), induced by beta-ionone. MDA-MB 435 cells were treated with different beta-ionone concentrations (25, 50, 100 and 200 micromol/L), with a negative

Anti-Cancer Effect of 3-Hydroxy-β-Ionone Identified from Moringa oleifera Lam. Leaf on Human Squamous Cell Carcinoma 15 Cell Line

Numai utilizatorii înregistrați pot traduce articole

Squamous cell carcinoma is the most common type of head and neck cancer worldwide. Radiation and chemotherapy are general treatments for patients; however, these remedies can have adverse side effects and tumours develop drug resistance. Effective treatments still require improvement for cancer

Synthesis and anti-metastatic effects of novel chiral ionone alkaloid derivatives.

Numai utilizatorii înregistrați pot traduce articole

Novel chiral ionone alkaloid derivatives were synthesized and evaluated their anti-metastatic effects in human MDA-MB-231 breast cancer cells. The chiral center C-6 of derivatives exerted an important role in response to the anti-metastatic activity. Comparing with a positive control of LY294002,

Synthesis and in vitro characterization of ionone-based chalcones as novel antiandrogens effective against multiple clinically relevant androgen receptor mutants.

Numai utilizatorii înregistrați pot traduce articole

A crucial event in prostate cancer progression is the transition from a hormone-sensitive to a lethal castration-refractory disease state. The antagonist-to-agonist conversion due to mutation in AR is a critical problem with the current clinically used antiandrogens. We aim to identify novel

β-ionone inhibits nonalcoholic fatty liver disease and its association with hepatocarcinogenesis in male Wistar rats.

Numai utilizatorii înregistrați pot traduce articole

Among the primary neoplasias that affect the liver, hepatocellular carcinoma (HCC) is the most frequent and the third leading cause of death related to cancer. Several risk factors predispose individuals to HCC such as nonalcoholic fatty liver disease (NAFLD), whose incidence has significantly

Apoptosis and cell-cycle arrest in human and murine tumor cells are initiated by isoprenoids.

Numai utilizatorii înregistrați pot traduce articole

Diverse classes of phytochemicals initiate biological responses that effectively lower cancer risk. One class of phytochemicals, broadly defined as pure and mixed isoprenoids, encompasses an estimated 22,000 individual components. A representative mixed isoprenoid, gamma-tocotrienol, suppresses the

β-Ionone derived chalcones as potent antiproliferative agents.

Numai utilizatorii înregistrați pot traduce articole

A series of β-ionone derived chalcones were evaluated for cytotoxic activity against various human cancer cell lines using SRB dye assay. All the compounds displayed moderate to high cytotoxic effect against almost all the cancer cell lines. The results also revealed the effect of substituents of

β-ionone inhibits persistent preneoplastic lesions during the early promotion phase of rat hepatocarcinogenesis: TGF-α, NF-κB, and p53 as cellular targets.

Dietary isoprenic derivatives such as β-ionone (βI) are a promising class of chemopreventive agents. In this study, cellular aspects of βI protective activities during early hepatocarcinogenesis were evaluated. Male Wistar rats were submitted to "resistant hepatocyte" model and then received daily

Polyphenolic Profile and Targeted Bioactivity of Methanolic Extracts from Mediterranean Ethnomedicinal Plants on Human Cancer Cell Lines.

Numai utilizatorii înregistrați pot traduce articole

The methanol extracts of the aerial part of four ethnomedicinal plants of Mediterranean region, two non-seed vascular plants, Equisetum hyemale L. and Phyllitis scolopendrium (L.) Newman, and two Spermatophyta, Juniperus communis L. (J. communis) and Cotinus coggygria Scop. (C. coggygria), were

Gallein, a Gβγ subunit signalling inhibitor, inhibits metastatic spread of tumour cells expressing OR51E2 and exposed to its odorant ligand.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE We previously reported that the olfactory receptor OR51E2, overexpressed in LNCaP prostate cancer cells, promotes cell invasiveness upon stimulation of its agonist β-ionone, and this phenomenon increases metastatic spread. Furthermore, we showed that the induced cell invasiveness involves

Synthesis and in vitro characterization of ionone-based compounds as dual inhibitors of the androgen receptor and NF-κB.

Numai utilizatorii înregistrați pot traduce articole

Current therapeutic strategy for advanced prostate cancer is to suppress the androgen receptor (AR) signaling. However, lethal castration-resistant prostate cancer (CRPC) arises due to AR reactivation via multiple mechanisms, including mutations in the AR and cross-talk with other pathways such as

Efficacy of geraniol but not of β-ionone or their combination for the chemoprevention of rat colon carcinogenesis.

Numai utilizatorii înregistrați pot traduce articole

β-ionone (βI), a cyclic isoprenoid, and geraniol (GO), an acyclic monoterpene, represent a promising class of dietary chemopreventive agents against cancer, whose combination could result in synergistic anticarcinogenic effects. The chemopreventive activities of βI and GO were evaluated individually

β-Ionone attenuates LPS-induced pro-inflammatory mediators such as NO, PGE2 and TNF-α in BV2 microglial cells via suppression of the NF-κB and MAPK pathway.

Numai utilizatorii înregistrați pot traduce articole

β-Ionone, a precursor of carotenoids, possesses a variety of biological properties such as anti-cancerous, anti-mutagenic and anti-microbial activity. Nevertheless, anti-inflammatory effects of β-ionone remain unknown. In this study, we investigated whether ION attenuates the expression of

Synergistic effects of the combination of β-ionone and sorafenib on metastasis of human hepatoma SK-Hep-1 cells.

Numai utilizatorii înregistrați pot traduce articole

The combination of anti-cancer drugs with nutritional factors is a potential strategy for improving the efficacy of chemotherapy, particularly for hepatocellular carcinoma because its conventional therapies are mostly ineffective. Using a highly invasive hepatoma SK-Hep-1 cell line, we investigated

beta-Ionone enhances TRAIL-induced apoptosis in hepatocellular carcinoma cells through Sp1-dependent upregulation of DR5 and downregulation of NF-kappaB activity.

Numai utilizatorii înregistrați pot traduce articole

beta-Ionone (ION), an end-ring analogue of beta-carotenoid, has been known to inhibit tumor cell growth and induce apoptosis in various types of cancer cells. Nevertheless, its apoptosis-related molecular mechanisms remain unclear. Here, we first investigated the molecular mechanisms by which ION
