TURMERIC EXTRACT POTENTIAL INHIBIT INFLAMMATORY MARKER IN LPS-STIMULATED MARCOPHAGE CELLS
Objective: Inflammation can be induced by microbiological, chemical, physical factors and plays roles in inflammatory diseases. Turmeric (Curcuma longa L.) has been widely used to provide a diverse array of biological activities, including anti-inflammatory, antimicrobial, also antioxidant. The Turmeric extract (TE) anti-inflammatory potential was conducted using a Lipopolysaccharide (LPS)-induced RAW264.7 macrophage cell line by inhibiting inflammatory mediators especially IL-6, PGE-2, IL-1β, COX-2, TNF-α, iNOS, also NO level.
Methods: The TE safe concentration in LPS-induced macrophage cell line was measured using MTS assay for further assay. The inflammatory markers (IL-6, PGE-2, COX-2, IL-1β, TNF-α, iNOS, NO) were measured using ELISA assay and NO by the nitrate/nitrite colorimetric assay in LPS-induced RAW264.7 cell line. LPS induced inflammatory marker by increasing inflammatory marker (IL-6, PGE-2, COX-2, IL-1β, TNF-α, iNOS, NO).
Results: TE with 100 to 25 µg/ml, caused a significant reduction of cells viability, reaching only 30.27 % live cells. TE with lower concentrations (7.5; 5; 2.5 µg/ml) had no cytotoxic effect on macrophage cells (viability 117.31-131.08 %). LPS induction caused an increase in inflammatory cytokines IL-1β, PGE-2, IL-6, COX-2, TNF-α as well as iNOS and NO. Turmeric extract caused the reduction of the inflammatory cytokines in a dose-dependent manner.
Conclusion: The research resulted that TE has anti-inflammatory activity by decreasing IL-6, PGE-2, COX-2, IL-1β, TNF-α, iNOS, and NO level on LPS-induced RAW264.7 cells
Anti-inflammatory and antiaging properties of chlorogenic acid on UV-induced fibroblast cell
Background Skin aging is the most common dermatological problem caused by intrinsic and extrinsic factor, such as exposure to (ultraviolet) UV rays. Chlorogenic acid (CA) is a phenolic compound which is known for its antioxidant properties against oxidative stress. Objective This study investigates the antiaging and anti-inflammatory properties of CA on UV-induced skin fibroblast cells. Methods Anti-inflammatory properties of CA were assessed by measuring inflammatory-related proteins IL-1β and TNF-α, while antiaging properties of CA were assessed by measuring reactive oxygen species (ROS), apoptosis, live and necrotic cells, and COL-3 gene expression level. Results Treating UV-induced skin fibroblast cells with CA decreased the level of ROS, IL-1β, TNF-α, apoptotic cells, and necrotic cells and increased live cells and COL-3 gene expression. Conclusion CA has the potential as the protective compound against inflammation and aging by decreasing the level ROS, pro-inflammatory cytokines IL-1β and TNF-α, apoptotic cells, and necrotic cells and by increasing live cells and COL-3 gene expression
