Effects of Propolis and Phenolic Acids on Triple-Negative Breast Cancer Cell Lines: Potential Involvement of Epigenetic Mechanisms.

Numai utilizatorii înregistrați pot traduce articole

Triple-negative breast cancer is an aggressive disease frequently associated with resistance to chemotherapy. Evidence supports that small molecules showing DNA methyltransferase inhibitory activity (DNMTi) are important to sensitize cancer cells to cytotoxic agents, in part, by reverting the

Characterization of phenolic extracts from Brava extra virgin olive oils and their cytotoxic effects on MCF-7 breast cancer cells.

Numai utilizatorii înregistrați pot traduce articole

The aim of the present work was to evaluate the phenolic profile of the 'Brava' extra virgin olive oil and assess its potential as a "natural adjuvant" in combination with chemotherapy treatment. The total phenol content of the phenolic extracts was 764 mg gallic acid equivalents/kg and the total

Structure activity relationship analysis of phenolic acid phenethyl esters on oral and human breast cancers: the grey GM(0, N) approach.

Numai utilizatorii înregistrați pot traduce articole

This paper presents grey structure activity relationship analysis for phenolic acid phenethyl esters from the bioactivity on oral cancer SAS, OEC-M1 and human breast cancer MCF-7. First of all, 14 compounds of phenolic acid phenethyl esters are synthesized, while the bioactivity (cytotoxicity) on

Differential Response of Two Human Breast Cancer Cell Lines to the Phenolic Extract from Flaxseed Oil.

Numai utilizatorii înregistrați pot traduce articole

Many studies have evidenced that the phenolic components from flaxseed (FS) oil have potential health benefits. The effect of the phenolic extract from FS oil has been evaluated on two human breast cancer cell lines, MCF7 and MDA-MB231, and on the human non-cancerous breast cell line, MCF10A, by SRB

Enhanced formation of non-phenolic androgen metabolites with intrinsic oestrogen-like gene transactivation potency in human breast cancer cells: a distinctive metabolic pattern.

Numai utilizatorii înregistrați pot traduce articole

Breast cancer is a sex steroid hormone-dependent malignant neoplasia. The role of oestradiol in this malignancy has been well documented; however, the involvement of androgens has remained controversial. To determine the role of non-phenolic androgen metabolites in human breast cancer, we studied

Cytotoxic impact of phenolics from Lamiaceae species on human breast cancer cells.

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to evaluate the cytotoxicity of dried aqueous extracts from Thymus serpyllum (ExTs), Thymus vulgaris (ExTv), Majorana hortensis (ExMh), and Mentha piperita (ExMp), and the phenolic compounds caffeic acid (CA), rosmarinic acid (RA), lithospermic acid (LA),

Dietary Phenolics against Breast Cancer. A Critical Evidence-Based Review and Future Perspectives

Numai utilizatorii înregistrați pot traduce articole

Breast cancer (BC) is the most common malignancy and the leading cause of cancer-related death in adult women worldwide. Over 85% of BC cases are non-hereditary, caused by modifiable extrinsic factors related to lifestyle, including dietary habits, which play a crucial role in cancer prevention.

Phenolic Acid Subclasses, Individual Compounds, and Breast Cancer Risk in a Mediterranean Cohort: The SUN Project.

Numai utilizatorii înregistrați pot traduce articole

Biological and epidemiological evidence supports an inverse association of phenolic acids with obesity-related chronic diseases. However, no previous study has prospectively evaluated the relationship between subclasses and individual compounds of phenolic acids and the risk of

Crude phenolic extracts from extra virgin olive oil circumvent de novo breast cancer resistance to HER1/HER2-targeting drugs by inducing GADD45-sensed cellular stress, G2/M arrest and hyperacetylation of Histone H3.

Numai utilizatorii înregistrați pot traduce articole

Characterization of the molecular function of complex phenols naturally present in extra virgin olive oil (EVOO) against the HER2-gene amplified JIMT-1 cell line, a unique breast cancer model that inherently exhibits cross-resistance to multiple HER1/2-targeted drugs including trastuzumab,

Combining doxorubicin with a phenolic extract from flaxseed oil: Evaluation of the effect on two breast cancer cell lines.

Numai utilizatorii înregistrați pot traduce articole

Breast cancer is one of the most frequently diagnosed forms of cancer and different treatments are used to block its progression. However, it still represents a very common cause of death in women. Doxorubicin (Dox) is reported as an effective agent in breast cancer treatment nonetheless it induces

Comparative study of photodynamic activity of methylene blue in the presence of salicylic acid and curcumin phenolic compounds on human breast cancer.

Numai utilizatorii înregistrați pot traduce articole

Curcumin and salicylic acid are both phenolic compounds and they can both affect cancer treatment efficacy. In this study, the effects of methylene blue-curcumin (CU-MB) and methylene blue-salicylic acid (SA-MB) ion pair complexes on MDA-MB-231 human breast cancer cells are studied. According to the

Influence of anthocyanins, derivative pigments and other catechol and pyrogallol-type phenolics on breast cancer cell proliferation.

Numai utilizatorii înregistrați pot traduce articole

Anthocyanins (cyanidin-3-glucoside (Cy-3-gluc) and delphinidin-3-glucoside (Dp-3-gluc)) and their respective vinylpyranoanthocyanin-catechins (portisins) were studied in order to evaluate the cytotoxicity effect on the estrogen responsive human breast cancer cell line (ER+) MCF-7 and their effect on

Breast cancer chemoprevention by dietary natural phenolic compounds: specific epigenetic related molecular targets.

Numai utilizatorii înregistrați pot traduce articole

Breast cancer is a systemic malignant disease that is a major cause of cancer-related death among women worldwide. Recently, multiple lines of evidence from epidemiologic studies have suggested that epigenetic and genetic changes are involved in breast cancer development. In breast cancer patients,

Antitumor potential of dark sweet cherry sweet (Prunus avium) phenolics in suppressing xenograft tumor growth of MDA-MB-453 breast cancer cells

Numai utilizatorii înregistrați pot traduce articole

This study investigated in vivo the antitumor activity of dark sweet cherry (DSC) whole extracted phenolics (WE) and fractions enriched in anthocyanins (ACN) or proanthocyanidins (PCA) in athymic mice xenografted with MDA-MB-453 breast cancer cells. Mice were gavaged with WE, ACN or PCA extracts

Dark Sweet Cherry ( Prunus avium) Phenolics Enriched in Anthocyanins Induced Apoptosis in MDA-MB-453 Breast Cancer Cells through MAPK-Dependent Signaling and Reduced Invasion via Akt and PLCγ-1 Downregulation

Numai utilizatorii înregistrați pot traduce articole

Dark sweet cherries (DSCs) are rich source of phenolics known to exert anticancer and anti-invasive activities. This study elucidated the molecular mechanisms underlying the activity of DSC phenolics against MDA-MB-453 breast cancer cells In Vitro. Cells were treated with DSC phenolics in whole
