Nobiletin is a poly-methoxylated flavone from the citrus peel that improves memory loss. Nobiletin is a retinoid acid receptor-related orphan receptors (RORs) agonist. Nobiletin can reduce reactive oxygen species (ROS) levels in differentiated C2C12 myotubes and has anti-inflammation and anti-cancer properties, including anti-angiogenesis, anti-proliferation, anti-metastasis and induced apoptosis.
Nobiletin (0-100 μM; 24 hours; U2OS and HOS cells) treatment progressively reduces protein expressions of MMP-2 and MMP-9. In U2OS and HOS cells, Nobiletin considerably reduces the phosphorylation of p-IKKα/β and p-IκBα, and protein expression of NF-κB in the cell nuclear fraction with the concomitant increase of the NF-κB expression in the cytosolic fraction. Nobiletin down-regulates the p-CREB and the SP-1 expressions in the nuclear fraction, whereas Nobiletin does not affect c-Jun and c-Fos expressions.
Nobiletin (0-100 μM; 24 hours; U2OS and HOS cells) treatment significantly reduces mRNA expressions of MMP-2 and MMP-9 dose-dependently in U2OS and HOS cells.
Western Blot Analysis
Cell Line:
U2OS and HOS cells
Concentration:
0 μM, 25 μM, 50 μM, 75 μM, 100 μM
Incubation Time:
24 hours
Result:
Progressively reduced protein expressions of MMP-2 and MMP-9. Considerably reduced the phosphorylation of p-IKKα/β and p-IκBα, and protein expression of NF-κB in the cell nuclear fraction with the concomitant increase of the NF-κB expression in the cytosolic fraction. Down-regulated the p-CREB and the SP-1 expressions in the nuclear fraction in U2OS and HOS cells.

体内研究
Nobiletin (0.1% of regular diet; oral administration; daily; for 20 weeks; male C57BL/6 mice) treatment restores glucose homeostasis and promots energy expenditure and circadian activity in aged mice.
Animal Model:
20- to 22-month-old male C57BL/6 mice
Dosage:
0.1% of regular diet
Administration:
Oral administration; daily; for 20 weeks
Result:
Fully restored glucose tolerance in aged mice, and increased basal body temperature and cold tolerance in aged mice. Led to a twofold increase in distance run/day on voluntary wheels compared with aged regular diet-fed mice during the active phase.
