RA exerts a significant cytoprotective effect by scavenging intracellular ROS induced by UVB. RA also attenuates UVB-induced oxidative macromolecular damage, including protein carbonyl content, DNA strand breaks, and the level of 8-isoprostane. Furthermore, RA increases the expression and activity of superoxide dismutase, catalase, heme oxygenase-1, and their transcription factor Nrf2, which are decreased by UVB radiation. RA treatment recovers the protein expression levels of Nrf2 decreased by UVB exposure, and results in the translocation of Nrf2 protein from the cytosol into the nucleus. RA may protect cellular environments from free-radical damage and thereby, enhance the cellular antioxidant defense system[1]. Rosmarinic acid inhibits TNF-α-induced phosphorylation and degradation of IκB-α, as well as nuclear translocation of NF-κB heterodimer induced by TNF-α. It downregulates the expression of CCL11 and CCR3 via the inhibition of NF-κB activation signaling. Rosmarinic acid inhibits the Ca2+-dependent pathways of TCR-mediated signaling by inhibiting PLC-γ1 and Itk activities[2].

体内研究 RA improves histological and serum markers of liver damage and significantly ameliorates oxidative/nitrosative stress and inflammatory response in liver tissue. Additionally, RA prevents transforming growth factor-beta1 (TGF-b1) and alpha-smooth muscle actin (a-SMA) expression, suggesting suppression of profibrotic response. RA significantly inhibits the CCl4-induced apoptosis, which is evident from decreased cleavage of caspase-3. The hepatoprotective activity of RA coincides with enhanced NF-E2-related factor 2 (Nrf2) and hemeoxygenase-1 (HO-1) expression. Rosmarinic acid acts as a natural inducer of endogenous cellular antioxidant defense via activation of the Nrf2/HO-1 pathway[3].

推荐的实验操作(此推荐来自于公开的文献所以Selleck并不保证其有效性)

细胞实验:

[1]

- 合并
  • Cell lines: HaCaT cells
  • Concentrations: 0.625, 1.25, 2.5, or 5 μM
  • Incubation Time: 48 h
  • Method:

    Cells are treated with RA (0.625, 1.25, 2.5, or 5 μM) and exposed to UVB radiation 1 h later. They are then incubated at 37°C for 48 h. At this time, MTT is added to each well to obtain a total reaction volume of 200 μl. After 4 h incubation, the supernatant is removed by aspiration. The formazan crystals in each well are dissolved in dimethyl sulfoxide (DMSO; 150 μl), and the absorbance at 540 nm is measured on a scanning multi-well spectrophotometer.
