hesperetin/breast neoplasms

The effectiveness of chemotherapy in breast cancer treatment can be increased using a combinatorial agent. Hesperetin has been reported to increase the sensitivity of doxorubicin in breast cancer cells; however, the underlying molecular mechanism remains unclear. This present study was conducted to

Nobiletin (NOB) and hesperetin (HES) are the citrus polymethoxyflavone and flavonone. Aromatase or cytochrome P450 (CYP19) enzyme is a key enzyme in estrogen biosynthesis. The objective of this study was to investigate the combinational effects of HES, NOB and letrozole (LET) as aromatase inhibitors

Aromatase is a key enzyme in estrogen synthesis, and aromatase inhibitors (AIs) have been developed for treating estrogen-responsive breast cancer. Because of its nondiscriminatory inhibition of estrogen synthesis, patients treated with AIs also contract diseases typically associated with estrogen

Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in females as per the global cancer project (GLOBOCAN 2018) estimates of breast cancer incidence and mortality produced by the International Agency for Research on Cancer (IARC). In 2018, there will be

The flavanone hesperetin is known to decrease basal glucose uptake, although the inhibitory mechanism is largely unknown. Here, we used MDA-MB-231 breast cancer cells to investigate the molecular pathways affected by hesperetin. The results indicate that the suppression of glucose uptake is caused

This study was to investigate the effects of hesperetin on cell proliferation and cell cycle arrest and explored the mechanism for these effects in breast carcinoma MCF-7 cells. Hesperetin significantly inhibited cell proliferation in a dose-dependent manner after treatment for 48 and 72 h and

Palm oil, unlike many other dietary oils, does not increase the yield of chemically-induced mammary tumors in rats when fed at high levels in the diet. This difference appears to be due to the vitamin E fraction of palm oil, which is rich in tocotrienols, since palm oil stripped of this fraction

Sulfonation is an important metabolic pathway for hesperetin. However, the mechanisms for the cellular disposition of hesperetin and its sulfate metabolites are not fully established. In this study, disposition of hesperetin via the sulfonation pathway was investigated using human embryonic kidney

Multidrug transporters influence drug distribution in vivo and are often associated with tumour drug resistance. Here we show that plant-derived polyphenols that interact with P-glycoprotein can also modulate the activity of the recently discovered ABC transporter, breast cancer resistance protein

Purpose: In vitro and in vivo studies suggested that flavonols, flavones, flavanones and flavan-3-ols have preventive effects on breast carcinogenesis. Epidemiological evidence about the associations between these flavonoid biomarkers and

OBJECTIVE The purpose of this study was to determine the dynamic parameter (EC50) of flavonoids apigenin, biochanin A, chrysin, genistein, kaempferol, hesperetin, naringenin, and silymarin for breast cancer resistance protein (BCRP) inhibition when used alone, and to evaluate their potential

While preclinical studies suggest the breast cancer (BC) chemopreventive effects of dietary polyphenols, the human evidence is still very weak. The huge existing in vitro-in vivo gap is mainly due to the plethora of potential effects reported by in vitro studies that usually assay polyphenols as

Metabolism and transport from intestinal cells back into the lumen by ATP-binding cassette (ABC) transporters is believed to limit the bioavailability of flavonoids. We studied metabolism and transport of the citrus flavonoid hesperetin, the aglycone of hesperidin, using a two-compartment transwell

Metabolism by phase II enzymes and transport from intestinal cells back into the lumen by ATP binding cassette (ABC) transporters limits the bioavailability of the flavanone hesperetin, the aglycone of hesperidin. This study investigates to what extent other flavonoids modulate the metabolism and
