Therapeutic implication of carbon monoxide in drug resistant cancers

Area of Science:

• Oncology
• Biochemistry
• Molecular Biology

Background:

• Drug resistance is a primary challenge in cancer therapy.
• Gas signaling molecules, like carbon monoxide (CO), are emerging as potential solutions.
• CO affects cancer cell metabolism, angiogenesis, and homeostasis.

Purpose of the Study:

• To review research on using CO to treat drug-resistant cancers over the last decade.
• To interpret the mechanisms by which CO combats drug resistance.
• To discuss challenges and propose solutions for CO-based cancer therapy.

Main Methods:

• Literature review of studies on carbon monoxide in cancer treatment.
• Analysis of molecular mechanisms underlying CO's effects on cancer cells.
• Discussion of clinical challenges and future directions.

Main Results:

• CO inhibits mitochondrial respiration and glycolysis, crucial ATP production pathways in cancer cells.
• CO suppresses angiogenesis, a process vital for tumor growth.
• CO exhibits synergistic effects when combined with conventional therapies like cisplatin, doxorubicin, and phototherapy in resistant cancer cells.

Conclusions:

• Carbon monoxide demonstrates significant potential in overcoming cancer drug resistance through multifaceted mechanisms.
• Further research and development are needed to address challenges and optimize CO-based therapeutic strategies.
• CO holds promise as an adjunct therapy to enhance the efficacy of existing cancer treatments.
