Gambogic Acid / FasL Cancer Research Results

GamB, Gambogic Acid: Click to Expand ⟱
Features:
Gambogic acid is a naturally occurring xanthonoid extracted from the resin of trees belonging to the Garcinia genus—most notably, Garcinia hanburyi. This tree is native to regions in Southeast Asia, particularly found in areas of China, India, and neighboring countries.
Gambogic acid (GA; C38H44O8, MW: 628.76), a polyprenylated xanthone and a widely used coloring agent, is the main active ingredient of gamboges secreted from the Garcinia hanburyi tree ([3, 4], which mainly grows in Southeast Asia.
GA has been approved by the Chinese FDA for the treatment of solid cancers in Phase II clinical trials.

Pathways:
-evidence suggesting that it can inhibit thioredoxin reductase (TrxR).
-can indeed lead to an increase in reactive oxygen species (ROS) levels
-Gambogic acid can trigger mitochondrial dysfunction, leading to cytochrome c release
-influences death receptors
-Inhibition of NF-κB Signaling
-Inhibition of VEGF Pathway
-Cell Cycle Arrest:
-p53 Activation
Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Thioredoxin / Thioredoxin reductase (Trx / TrxR) ↓ Trx / TrxR activity Redox buffering collapse Primary molecular target; covalent cysteine interaction drives loss of antioxidant capacity (ref)
2 ROS accumulation ↑ ROS Oxidative stress overload Immediate consequence of Trx/TrxR inhibition; upstream of mitochondrial damage (ref)
3 Mitochondrial integrity (ΔΨm) ↓ ΔΨm Mitochondrial dysfunction GA reduces mitochondrial membrane potential prior to execution-phase death (ref)
4 Intrinsic apoptosis / pyroptosis (caspase-3, GSDME) ↑ programmed cell death Execution-phase killing Mitochondrial apoptosis and caspase-3/GSDME-dependent pyroptosis reported (ref)
5 NF-κB signaling ↓ NF-κB activation Reduced pro-survival transcription Redox-sensitive suppression of NF-κB nuclear activity and target genes (ref)
6 PI3K–AKT survival signaling ↓ AKT phosphorylation Survival pathway collapse Downstream of oxidative stress and chaperone disruption (ref)
7 HSP90 chaperone function ↓ client stabilization Oncoprotein destabilization GA disrupts HSP90–client interactions affecting AKT, HER2, etc. (ref)
8 ER stress / UPR ↑ ER stress signaling Proteotoxic stress Secondary ER stress response following redox and mitochondrial disruption (ref)
9 Cell cycle regulation ↑ cell-cycle arrest Proliferation blockade Checkpoint activation downstream of stress signaling (ref)
10 Autophagy (stress-induced) ↑ autophagy Adaptive or pro-death response Autophagy induction reported; role varies by context (ref)
11 Angiogenesis signaling (VEGF) ↓ VEGF expression Anti-angiogenic effect Suppression of pro-angiogenic transcription observed (ref)
12 Tumor growth in vivo ↓ tumor volume Integrated outcome Xenograft models show significant tumor growth inhibition (ref)


FasL, Fas ligand: Click to Expand ⟱
Source:
Type:
Fas ligand (FasL) is a protein that plays a crucial role in the regulation of the immune system and programmed cell death, also known as apoptosis. In the context of cancer, FasL has been found to have both tumor-promoting and tumor-suppressing effects.
FasL is upregulated in melanoma, colon.
FasL: tumor suppressing effect on Breast and Lung cancer.

FasL inhibitors, which block the interaction between Fas and FasL, have been shown to enhance the effectiveness of chemotherapy and immunotherapy
