Marine-derived L-asparaginase: unlocking marine power in anti-tumor therapeutics

Area of Science:

• Biotechnology and Marine Microbiology
• Enzymology and Cancer Therapeutics

Background:

• L-asparaginase, a vital enzyme in cancer treatment, is traditionally sourced from microbial production.
• Research is actively seeking alternative L-asparaginase sources with enhanced stability, lower immunogenicity, and higher activity.
• Marine microorganisms are emerging as a significant focus for novel L-asparaginase discovery.

Purpose of the Study:

• To review the molecular structure and production genes of marine-derived L-asparaginase.
• To explore the roles of L-asparaginase in cancer metabolism, including apoptosis and immune response.
• To summarize clinical applications and combination therapies involving L-asparaginase for various cancers.

Main Methods:

• Literature review focusing on marine microbial sources of L-asparaginase.
• Analysis of L-asparaginase's molecular structure, genetic basis, and functional roles in cancer.
• Compilation of data from clinical studies on L-asparaginase in leukemia and solid tumors.

Main Results:

• Marine microorganisms represent a rich source for L-asparaginase with unique characteristics.
• L-asparaginase plays multifaceted roles in cancer, including asparagine depletion, apoptosis induction, and immune modulation.
• Clinical studies demonstrate L-asparaginase efficacy in acute lymphoblastic leukemia and potential in solid tumors, especially in combination therapies.

Conclusions:

• Marine-derived L-asparaginase variants offer significant potential for improved cancer therapy.
• Further exploration of marine microbial resources can unlock novel enzymes for broader therapeutic applications.
• Harnessing marine L-asparaginase could revolutionize cancer prevention and treatment strategies.
