# Usnic Acid Evidence by Cancer Type

Current research highlights meaningful usnic-acid findings across several cancer types.

### Breast cancer

Themes include apoptosis, autophagy, anti-inflammatory signalling, anti-angiogenic effects, and in vivo tumour-growth inhibition.

### Lung cancer

Themes include reduced proliferation, migration, and invasion, plus synergy interest with paclitaxel and cetuximab.

### Colon cancer

Themes include cell-cycle arrest, apoptosis, EMT suppression, and metabolic disruption.

### Gastric cancer

This is one of the clearer in vivo contexts in the source material, including comparisons against 5-FU.

### Prostate cancer

Themes include apoptosis, NF-κB suppression, and reduced motility.

### Ovarian cancer

Themes include cell-cycle arrest, apoptosis, and lower migration or invasion potential.

### Glioma and BBB-relevant contexts

UA has shown BBB relevance in model systems, making brain-tumour contexts more plausible than for many compounds.

### AML-related signalling context

The source material also highlights integrated-stress-response work suggesting sensitisation of AML cells to BCL-2 inhibition.

### Bottom line

The signal is broad rather than tumour-type narrow.

That supports UA as a mechanistically flexible investigational adjunct, but not as a validated clinical treatment for any one cancer type yet.
