PLB, Plumbagin: Click to Expand ⟱
Features:
Plumbagin (5-hydroxy-2-methyl-1,4-naphthoquinone) is a naturally occurring naphthoquinone derivative.

–Plumbagin can undergo redox cycling to generate reactive oxygen species (ROS)
-apototosis, activation of caspases, modulation of Bax, Bcl‑2, loss of MMP.
-Cell cycle arrest in cancer cells, often at the G0/G1, or G2/M phases.
-May inhibit NF‑κB activation
– MAPK Pathways
– PI3K/Akt Pathway
-Downregulation of (VEGF) and matrix metalloproteinases (MMPs).

-Seems capable of raising ROS in normal and cancer cells (#2004)

-ic50 cancer cells 1-10uM, normal cells >10uM

Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 Oxidative stress (redox cycling) ↑ ROS Upstream cytotoxic trigger Plumbagin induces ROS; ROS generation is causally linked to cell death in cancer models (ref)
2 Mitochondrial integrity (ΔΨm) ↓ ΔΨm Mitochondrial dysfunction Loss of mitochondrial membrane potential occurs during plumbagin-induced apoptotic progression (ref)
3 Intrinsic apoptosis (caspase cascade) ↑ caspase-dependent apoptosis Programmed cell death Plumbagin triggers apoptosis in leukemia and solid tumor cells; antioxidant rescue attenuates killing (ref)
4 NF-κB signaling ↓ NF-κB activation Reduced pro-survival / inflammatory transcription Demonstrates plumbagin suppresses NF-κB signaling in tumor/immune contexts (direction explicitly shown) (ref)
5 STAT3 signaling ↓ STAT3 phosphorylation Reduced survival & proliferation signaling Plumbagin suppresses constitutive and inducible STAT3 phosphorylation in cancer cells (ref)
6 PI3K–AKT–mTOR signaling ↓ PI3K/AKT/mTOR activity Survival pathway suppression Plumbagin inhibits PI3K/AKT/mTOR signaling in cancer cells with linked apoptosis/autophagy outcomes (ref)
7 Autophagy program ↑ autophagy Stress response (context-dependent role) Plumbagin induces autophagy alongside apoptosis; pathway involvement (p38, PI3K/AKT/mTOR) is demonstrated (ref)
8 Stress MAPK (p38 MAPK) ↑ p38 activation Stress signaling amplification p38 MAPK activation is implicated in plumbagin-driven apoptosis/autophagy signaling in cancer cells (ref)
9 Cell cycle control ↑ G2/M (or S–G2/M) arrest Proliferation blockade Plumbagin induces checkpoint arrest with changes in cyclins/CDKs consistent with growth inhibition (ref)
10 Death receptor axis (TRAIL receptors DR4/DR5) ↑ DR4/DR5 expression Sensitizes to TRAIL-mediated killing Plumbagin increases DR4/DR5 and enhances TRAIL killing; NAC blocks both ROS and receptor upregulation (ref)
11 EMT / invasion programs ↓ EMT (anti-invasive) Reduced metastasis-related phenotype Plumbagin suppresses epithelial–mesenchymal transition and stemness-related markers in cancer cells (ref)
12 Angiogenesis signaling (VEGFR2/VEGF-driven endothelial responses) ↓ angiogenesis signaling / function Anti-angiogenic effect Plumbagin inhibits tumor angiogenesis via interference with VEGFR2-mediated signaling in endothelial/tumor models (ref)


BAX, Apoptosis regulator BAX: Click to Expand ⟱
Source:
Type: Proapototic protein
BAX is a member of the Bcl-2 gene family.
Pro-apoptotic protein that forms heterodimers with anti-apoptotic BCL2 proteins; involved in various cellular activities and regulated by p53; mediates the release of cytochrome c from mitochondria.
