Correction for 'Different antitumor effects of quercetin, quercetin-3'-sulfate and quercetin-3-glucuronide in human breast cancer MCF-7 cells' by Qiu Wu et al., Food Funct., 2018, 9, 1736-1746.
This study was designed to investigate the tumor-inhibitory effects of quercetin (Que) and its water-soluble metabolites, quercetin-3'-sulfate (Q3'S) and quercetin-3-glucuronide (Q3G), as well as to make the molecular mechanism and structure-antitumor relationship clear. It was found that Que, Q3'S,
In the present study the effect of quercetin and its major metabolites quercetin-3-glucuronide (Q3G) and isorhamnetin on inflammatory gene expression was determined in murine RAW264.7 macrophages stimulated with lipopolysaccharide. Quercetin and isorhamnetin but not Q3G significantly decreased mRNA
BACKGROUND
Sanguisorba minor, as well as several other edible herbs and vegetables, has been used extensively in traditional medicine. The observed beneficial effects can be attributed at least in part to the direct modulation of several enzymatic activities by its polyphenolic
Our previous study showed that quercetin enhances the anticancer effect of trichostatin A (TSA) in xenograft mice given quercetin intraperitoneally (10 mg/kg, 3 times/week). Herein, we investigate whether quercetin administered orally exerts such an effect and prevents the cytotoxic side effects of
Acacia saligna and Lawsonia inermis natural populations growing in Northern Saudi Arabia might be a valuable source of polyphenols with potent biological activities. Using high-performance liquid chromatography-diode array detection (HPLC-DAD), several polyphenols were detected
Dietary flavonoids have been shown to have a number of anti-inflammatory properties, including decreasing the expression of adhesion molecules. Flavonoids however, are metabolised during absorption and the forms reaching the systemic circulation are glucuronidated, sulfated and methylated. Most
Cyclooxygenase-2 (COX-2)-catalysed synthesis of prostaglandin E2 plays a key role in inflammation and its associated diseases, such as cancer and cardiovascular disease. There are numerous reports demonstrating that flavonoids inhibit COX-2 activity. However, transcriptional regulation of COX-2 can
