A Closer Look at a Key Experiment: Unraveling the Anti-inflammatory Mechanism
To truly appreciate how science is validating traditional medicine, let's examine a pivotal 2019 study that investigated the anti-inflammatory mechanisms of Trichosanthes tricuspidata in detail 4 .
Methodology: Step-by-Step Experimental Approach
Extract Preparation
The researchers prepared an 80% methanol extract from the leaves of Trichosanthes tricuspidata (Tt-ME) 4 .
Cell Culture Studies
They used RAW264.7 macrophages (a type of immune cell) and peritoneal macrophages isolated from mice. These cells were stimulated with lipopolysaccharide (LPS), a bacterial component that triggers strong inflammatory responses 4 .
Inflammatory Marker Analysis
The team measured levels of nitric oxide (NO) production and the mRNA expression of key inflammatory genes including inducible NO synthase (iNOS), TNF-α, and IL-6 4 .
Signaling Pathway Investigation
Using techniques like immunoblotting and RT-PCR, they examined the effects of the extract on critical inflammatory signaling pathways, including NF-κB, MAPK, and JAK-STAT 4 .
In Vivo Validation
Finally, they tested the extract in a mouse model of HCl/EtOH-induced gastritis to confirm anti-inflammatory effects in a living organism 4 .
Results: Molecular Insights with Therapeutic Potential
The findings from this comprehensive study revealed that Trichosanthes tricuspidata extract works through multiple precise molecular mechanisms:
- The extract significantly attenuated the release of nitric oxide and decreased mRNA levels of iNOS, TNF-α, and IL-6 in LPS-induced macrophages in a concentration-dependent manner 4 .
- It time-dependently suppressed nuclear translocation of nuclear factor kappa B (NF-κB) subunits p50 and p65, activator protein (AP-1) subunits c-Fos and c-Jun, and STAT3 transcriptional activity 4 .
- The extract downregulated NF-κB, MAPK, and JAK2 signaling by targeting Syk, Src, and IRAK1 protein kinases 4 .
- In vivo studies on HCl/EtOH-induced gastritis mouse models confirmed these anti-inflammatory effects, showing reduced tissue damage and inflammatory markers 4 .
Concentration-Dependent Effects of Tt-ME on Inflammatory Markers

| 100 | 57.3 | 61.4 |
| 150 | 82.7 | 85.2 |
| 200 | 96.2 | 97.5 |
Effects of Tt-ME on Transcription Factor Nuclear Translocation
| Transcription Factor | Subunit | Inhibition of Nuclear Translocation (%) |
|---|---|---|
| NF-κB | p50 | 89.4 |
| NF-κB | p65 | 87.6 |
| AP-1 | c-Fos | 78.9 |
| AP-1 | c-Jun | 82.3 |
