Water Snake Peptide Shows Promise Against H. Pylori Infection and Stomach Cancer
ECCT, a new cathelicidin from the Chinese water snake, inhibits H. pylori growth and shows anti-gastric cancer activity.
Quick Facts
What This Study Found
Snake-derived ECCT peptide shows both anti-H. pylori activity and anti-gastric cancer properties.
Key Numbers
MIC determined against multiple pathogens; suppressed proinflammatory cytokine transcription; inhibited MAPK pathway.
How They Did This
cDNA cloning, phylogenetic/structural analysis, MIC determination, and anti-H. pylori and anti-cancer testing.
Why This Research Matters
H. pylori infects half the world's population and is the primary cause of gastric cancer — new treatment options are urgently needed.
The Bigger Picture
Snake venom and secretion peptides continue to yield promising drug leads, adding to antimicrobial and anticancer peptide libraries.
What This Study Doesn't Tell Us
In vitro study — bioavailability, stability in gastric acid, and in vivo efficacy need assessment.
Questions This Raises
- ?Could ECCT survive the acidic stomach environment to reach H. pylori?
- ?Is the anti-cancer effect direct or mediated through H. pylori clearance?
Trust & Context

Frequently Asked Questions
Can snake peptides treat stomach infections?
ECCT from the Chinese water snake kills H. pylori in lab tests and shows anti-cancer activity, but human studies are needed.
Why look to snakes for new antibiotics?
Reptiles produce diverse antimicrobial peptides as part of their immune system — these are largely unexplored as drug sources.
