Hepatic overproduction of apolipoprotein B (apoB)-containing lipoproteins is characteristic of the dyslipidemia associated with insulin resistance. Recently, we demonstrated that the flavonoid naringenin, like insulin, decreased apoB secretion from HepG2 cells by activation of both the phosphoinositide-3-kinase (PI3-K) pathway and the mitogen-activated protein kinase/extracellular-regulated kin...
Previous studies in our laboratory have demonstrated that naringenin produced antidepressant-like action in tail suspension test (TST). However, the underlying mechanisms involved in neurotrophin system by which naringenin works have not been investigated. The present study extends earlier works on the role of brain-derived neurotrophic factor (BDNF) in regulating the antidepressant-like action...
Excessive activation of the TLR4 signalling pathway is critical for inflammation-associated disorders, while negative regulators play key roles in restraining TLR4 from over-activation. Naringenin is a citrus flavonoid with remarkable anti-inflammatory activity, but the mechanisms underlying its inhibition of LPS/TLR4 signalling are less clear. This study investigated the molecular targets and ...
A novel single-step microbial transformation process for the efficient production of carthamidin and isocarthamidin from naringenin by yeast Rhodotorula marina in an aerated bioreactor was described. The biotransformation led to the total product concentration of 233 mg/l. The highest conversion efficiency observed for carthamidin was 0.31 mg/mg of naringenin and for isocarthamidin 0.47 mg/mg o...
Acute myeloid leukemia (AML) is a hematological malignancy with a low survival rate. Curcumin, which is a multi-targeted anticancer agent, has been shown to exert anti‐oxidant, anti‐inflammatory, anti‐mutagenic and anti-carcinogenic activities. Naringenin is extracted from citrus fruits and exerts anti-mutagenic and anti-carcinogenic activities in various types of cancer cells. However, the eff...
BACKGROUND & AIMS Symptoms of constipation are extremely common, especially in the elderly. The present study aim to identify an efficacious treatment strategy for constipation by evaluating the secretion-promoting and laxative effect of a herbal compound, naringenin, on intestinal epithelial anion secretion and a rat constipation model, respectively. METHODS/PRINCIPAL FINDINGS In isolated ra...
A number of natural phytochemicals have anti-photoaging properties that appear to be mediated through the inhibition of matrix metalloproteinase-1 (MMP-1) expression, but their direct target molecule(s) and mechanism(s) remain unclear. We investigated the effect of naringenin, a major flavonoid found in citrus, on UVB-induced MMP-1 expression and identified its direct target. The HaCaT human sk...
purpose: deformability/rheologic behavior of erythrocytes are related to near-surface membrane fluidity. specific agents can increase erythrocyte membrane fluidity in order to adjust hemodynamics in cardiovascular diseases. grapefruit flavanone naringenin has been proposed for potential use in an alternative therapy of cardiovascular conditions. in respect to this, we assessed here effects o...
Lipopolysaccharide (LPS) is the major structural component of Gram-negative bacteria cell wall and a highly pro-inflammatory toxin. Naringenin is found in Citrus fruits and exhibits antioxidant and anti-inflammatory properties through inhibition of NF-κB activation but its effects in LPS-induced inflammatory pain and leukocyte recruitment were not investigated yet. We investigated the effects o...
Chemical model reactions were carried out to investigate the effect of a citrus flavonoid, naringenin, on the formation of acrylamide under mild heating conditions. Results showed that naringenin significantly and dose dependently inhibited the formation of acrylamide (20-50% relative to the control), although not in a linear manner. Moreover, the presence of naringenin in acrylamide-producing ...
