One of the most challenging obstacles in nanoparticle's surface modification is to achieve the concept that one ligand can accomplish multiple purposes. Upon such consideration, 3-aminopropoxy-linked quercetin (AmQu), a derivative of a natural flavonoid inspired by the structure of dopamine, is
Polymer nanoparticles are vehicles used for delivery of hydrophobic anti-cancer drugs, like doxorubicin, paclitaxel or chemopreventors like quercetin (Q). The present study deals with the synthesis and characterisation of nano formulations (NFs) from Q loaded PLGA (poly lactic-co-glycolic acid) nano
Peroxisome proliferator-activated receptors-γ (PPAR-γ), a ligand-activated transcription factor, activated by several ligands like fatty acids (linoleic acid being the most common) or their metabolites, can function as potential therapeutic target for various cancers. Although various synthetic
The potential inhibitory effect of quercetin, a major plant flavonol, on breast cancer resistance protein (BCRP) activity was investigated in this study. The presence of quercetin significantly increased the cellular accumulation and associated cytotoxicity of the BCRP substrate mitoxantrone in
OBJECTIVE
This study investigated the quercetin (Que) effects on growth of MCF-7 human cancer breast cell line and its cellular death mechanism.
BACKGROUND
Quercetin has been found to be very efficacious against many different types of cancer cells. However, the study is not sufficiently powered to
Purpose: Lung cancer has a high incidence rate worldwide with a 5-year survival rate of 18%, and is the leading cause of cancer-related deaths. The aim of this study is to augment therapeutic efficacy of quercetin (QR) for lung cancer therapy by targeting transferrin receptors, which are
BACKGROUND
The bioflavonoid quercetin, a polyphenolic compound widely distributed in the plant kingdom, has been demonstrated to exert cytostatic activity against a variety of tumor cells in vitro and in vivo. It may be useful in cancer therapy as a thermosensitizer by increasing the cell killing
We sought to investigate the apoptosis-inducing activities of quercetin, Siamois 1, and Siamois 2 against invasive estrogen-receptor negative MDA-MB 435 cells xenografted in athymic nude mice. This study clearly demonstrated that these compounds exhibited apoptosis-inducing activities in cell
OBJECTIVE
Diet-derived flavonoids possess cancer chemopreventive properties in preclinical models. The knowledge of the pharmacology of most flavonoids is insufficient to warrant their advancement to clinical evaluation.
METHODS
Here the three flavonoids tricin from rice bran, apigenin from leafy
Quercetin is a bioflavonoid known for antioxidation and antiproliferation activities. We demonstrated that quercetin inhibited cancer cell growth and sensitized cancer cells to gemcitabine treatment by promoting apoptosis via inhibiting heat shock protein 70 expression. Our results suggest that
The consumption of vegetables containing the flavonols quercetin and kaempferol reduces the risk of cancer. We utilized human gut (HuTu-80 and Caco-2) and breast cancer cells (PMC42) to show the synergistic effect of quercetin and kaempferol in reducing cell proliferation. A trend in reduction of
Multidrug resistance has became the major obstacle to cancer chemotherapy. Recent studies suggest that quercetin could enhance the response of tumors to chemotherapy although the mechanism by which quercetin enhances the sensitivity of tumor cells to chemical drugs remains elusive. Therefore, in
Quercetin, a flavonoid abundantly present in plants, is widely used as a phytotherapy in prostatitis and prostate cancer. Although quercetin has been reported to have a number of therapeutic effects, the cellular target(s) responsible for its anti-cancer action has not yet been clearly elucidated.
BACKGROUND
It has been demonstrated that prostate cancer cells are relatively sensitive to heat stress. We have reported that heat treatment at 43 degrees C increases the expression of heat shock protein 70 (hsp70) in prostate cancer cells, leading to apoptosis. Hsp70 is a protein that protects
Therapy with 5-fluorouracil (5-FU) as a single agent has only limited success in palliative treatment of cancer of the large bowel. In the current study, the effect of quercetin on the action of 5-FU in the human colorectal cancer cell lines COLO 320 DM and COLO 205 was evaluated using the MTT and
