Bacillus thuringiensis: From biopesticides to anticancer agents.

Area of Science:

• Microbiology
• Biochemistry
• Oncology

Background:

• Bacillus thuringiensis (Bt) produces insecticidal Cry and Cyt proteins.
• Parasporins, cytotoxic proteins from Bt, show in vitro antitumor activity against human cancer cells.
• Nineteen parasporins across six families are known for their specific cancer cell activity.

Purpose of the Study:

• To review the properties of parasporins as natural antitumor agents.
• To focus on the in vivo activity of parasporins.
• To emphasize the importance of animal model studies for clinical oncology applications.

Main Methods:

• Literature review of parasporin research.
• Analysis of in vitro and in vivo studies on parasporins.
• Synthesis of current knowledge on parasporin antitumor properties.

Main Results:

• Parasporins exhibit significant in vitro antitumor activity against various cancer cell lines.
• There is a notable lack of in vivo data on parasporin efficacy and safety.
• Natural origin and specific cytotoxicity make them promising anticancer candidates.

Conclusions:

• Parasporins are potent natural compounds with demonstrated in vitro anticancer effects.
• Further in vivo research is crucial to validate their therapeutic potential for cancer treatment.
• Testing in animal models is essential for advancing parasporins towards clinical oncology.
