Reference Profile Correlation Reveals Estrogen-like Trancriptional Activity of Curcumin [PDF]

, 2010
Background: Several secondary metabolites from herbal nutrient products act as weak estrogens (phytoestrogens), competing with endogenous estrogen for binding to the estrogen receptors and inhibiting steroid converting enzymes.

Stability of quercetin in DMEM and cell culture with A549 cells

eFood, 2022
Quercetin is evidently unstable in Dulbecco's modified Eagle's medium (DMEM) at 37°C. However, the underlying mechanism of this instability is not clear yet. The stability and new degradation products of quercetin in DMEM at 37°C were investigated via in

Quercetin and Cancer Chemoprevention [PDF]

Evidence-Based Complementary and Alternative Medicine, 2011
Several molecules present in the diet, including flavonoids, can inhibit the growth of cancer cells with an ability to act as “chemopreventers”. Their cancer‐preventive effects have been attributed to various mechanisms, including the induction of cell‐cycle arrest and/or apoptosis as well as the antioxidant functions.

Prevention of quercetin precipitation in red wines: a promising enzymatic solution

OENO One, 2022
Flavonols are known for causing undesirable deposits in both red and white wines. Among flavonols, quercetin is widely considered the principal factor determining this phenomenon. One of the most accredited hypotheses claims that glycosylated derivatives

Multiple roles for UV RESISTANCE LOCUS8 in regulating gene expression and metabolite accumulation in arabidopsis under solar ultraviolet radiation [PDF]

, 2013
Photomorphogenic responses triggered by low fluence rates of ultraviolet B radiation (UV-B; 280–315 nm) are mediated by the UV-B photoreceptor UV RESISTANCE LOCUS8 (UVR8).

Diverse biological effects of glycosyltransferase genes from Tartary buckwheat [PDF]

, 2019
Background: Tartary buckwheat (Fagopyrum tataricum) is an edible cereal crop whose sprouts have been marketed and commercialized for their higher levels of anti-oxidants, including rutin and anthocyanin. UDP-glucose flavonoid glycosyltransferases (UFGTs)

In vitro catabolism of quercetin by human fecal bacteria and the antioxidant capacity of its catabolites

Food & Nutrition Research, 2014
Background: Part of quercetin flows into the colon after escaping the absorption of the small intestine and will be degraded by colonic microbiota. The catabolites in the colon partially determine the physiological activity of quercetin.
