Features:
Urolithins are gut microbiota–derived dibenzopyran-6-one metabolites formed from ellagitannins → ellagic acid. They are the bioactive, systemically relevant forms responsible for most of the anticancer, mitochondrial, and signaling effects attributed to pomegranate and berry consumption.
Ellagic acid itself is largely confined to the gut lumen; urolithins are what reach circulation and tissues.

Urolithin A (UA), Most studied; mitophagy, anticancer, anti-inflammatory
Humans fall into urolithin metabotypes:
Metabotype	Description	            Approx. Population
A	        Produces UA (best profile)	~40%
B	        Produces UB ± UA	       ~25–30%
0	        Non-producer	                ~30%

ROS Modulation (Context-Dependent)
Cancer cells:
-Mild ROS ↑ or redox stress → apoptosis, growth arrest
Normal cells:
-ROS ↓, improved mitochondrial efficiency

This duality is why urolithins are less chemo-antagonistic than classic antioxidants.

Anticancer Signaling
↓ PI3K/AKT/mTOR
↓ Wnt/β-catenin
↓ NF-κB, STAT3
Cell-cycle arrest (G1/S)

Unlike sulforaphane or NAC, urolithins:
-Do not strongly upregulate NRF2 in cancer cells
-May normalize NRF2 signaling in normal cells

Urolithin A–type activity — Cancer vs Normal Cell Effects
Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Mitophagy / mitochondrial quality control (PINK1–Parkin axis) ↑ mitophagy → loss of mitochondrial reserve ↑ mitophagy → improved mitochondrial fitness Driver Mitochondrial pruning and quality enforcement Urolithins selectively stress cancer cells by removing dysfunctional mitochondria while rejuvenating normal-cell mitochondrial pools
2 Mitochondrial metabolism / bioenergetics ↓ metabolic flexibility; ↓ ATP resilience ↑ oxidative efficiency Driver Energy stress vs optimization Cancer cells are less able to compensate for enforced mitochondrial turnover
3 Reactive oxygen species (ROS) ↑ ROS (secondary to mitochondrial stress) ↓ ROS Secondary Metabolism-linked redox shift ROS changes arise from altered mitochondrial populations, not direct redox cycling
4 AMPK / mTOR nutrient-sensing axis ↑ AMPK; ↓ mTOR signaling ↑ AMPK (adaptive) Secondary Catabolic pressure and growth restraint Energy-sensing pathways reinforce growth suppression in metabolically stressed tumor cells
5 Cell cycle regulation ↓ proliferation / ↑ arrest ↔ spared Phenotypic Cytostatic growth limitation Growth inhibition reflects bioenergetic insufficiency rather than direct CDK inhibition
6 Inflammatory signaling (NF-κB / cytokines) ↓ pro-tumor inflammation ↓ inflammatory tone Secondary Anti-inflammatory modulation Reduced inflammation contributes to chemopreventive and microenvironmental effects
7 NRF2 antioxidant response ↑ NRF2 (adaptive, secondary) ↑ NRF2 (protective) Adaptive Redox homeostasis reinforcement NRF2 activation reflects improved mitochondrial quality and reduced oxidative burden rather than a cytotoxic mechanism
8 Apoptosis sensitivity ↑ sensitivity to apoptosis (stress-context dependent) ↓ apoptosis Phenotypic Threshold-dependent cell death Apoptosis occurs when mitochondrial and energetic stress exceed adaptive capacity


Casp3, CPP32, Cysteinyl aspartate specific proteinase-3: Click to Expand ⟱

Type:
Also known as CP32.
Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death.
As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression.
Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy.
Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent.
On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer.
Procaspase-3 is a apoptotic marker protein.
Prognostic significance:
• High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers.
• Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers.
