Description

Luteolin (also known as Luteoline), a flavonoid compound, is a potent inhibitor of Nrf2. It possesses anti-inflammatory and anti-cancer properties, inducing apoptosis and cell cycle arrest, and inhibiting metastasis and angiogenesis in various cancer cell lines, including human non-small lung cancer cells.

Signaling Pathway

-

In Vitro Study

Luteolin treatment (0-160 µM; 24 hours; NCI-H460 cells) inhibits the viability of NCI-H460 cells in a concentration-dependent manner. Treatment with Luteolin (20-80 µM; 24 hours; NCI-H460 cells) leads to an accumulation of cells in the S phase. Moreover, treatment with Luteolin (320-580 µM; 48 hours; NCI-H460 cells) induces apoptosis. Additionally, Luteolin treatment (20-80 µM; 24 hours; NCI-H460 cells) increases the protein expression levels of apoptotic regulatory proteins, such as the Bax/Bcl-2 ratio, in a concentration-dependent manner. However, only 80 µM Luteolin inhibits the expression of Bad. Furthermore, Luteolin decreases the expression of Sirt1 in the NCI-H460 cell line in a concentration-dependent manner.

In Vivo Study

Luteolin (10-100 mg/kg; oral gavage; daily; for 12 weeks; adult male Wistar rats) exhibits antioxidant properties and can effectively protect against non-alcoholic steatohepatitis by targeting the pro-inflammatory IL-1 and Il-18 pathways in rats fed with a high carbohydrate/high fat diet.
