Abstract:
Multidrug resistance (MDR) in cancer remains a critical obstacle for efficient chemotherapy. Many MDR reversal agents have been discovered but failed in clinical trials due to severe toxic effects. Gaseous signaling molecules (GSMs), such as oxygen, nitric oxide, hydrogen sulfide and carbon monoxide, play key roles in regulating cell biological function and MDR. Compared with other toxic chemosensitizing agents, GSMs are endogenous and biocompatible molecules with little side effects. Research show that GSM modulators, including pharmaceutical formulations of GSMs (combined with conventional chemotherapeutic drugs) and GSM-donors (small molecules with GSMs releasing property), can overcome or reverse MDR. This review discusses the roles of these four GSMs in modulating MDR, and summarizes GSMs modulators in treating cancers with drug resistance.
Insights
Gaseous signaling molecules (GSMs) can reverse cancer multidrug resistance (MDR) with fewer side effects than traditional agents. GSM modulators offer a promising strategy for overcoming chemotherapy resistance in cancer treatment.
Area of Science:
- Biochemistry and Molecular Biology
- Cancer Research
- Pharmacology
Background:
- Multidrug resistance (MDR) significantly limits chemotherapy efficacy.
- Existing MDR reversal agents often cause severe toxicity, hindering clinical application.
- Gaseous signaling molecules (GSMs) are endogenous, biocompatible regulators of cellular functions, including MDR.
Purpose of the Study:
- To review the role of four key GSMs (oxygen, nitric oxide, hydrogen sulfide, carbon monoxide) in modulating cancer MDR.
- To summarize GSM modulators as potential therapeutic agents for drug-resistant cancers.
Main Methods:
- Literature review of research on GSMs and their effects on MDR.
- Analysis of studies involving pharmaceutical formulations of GSMs and GSM-donors.
- Evaluation of clinical trial data and preclinical research on GSM modulators.
Main Results:
- GSMs play crucial roles in regulating cellular processes relevant to MDR.
- GSM modulators, including combined therapies and GSM-releasing molecules, demonstrate potential in overcoming MDR.
- GSMs exhibit low toxicity compared to conventional chemosensitizing agents.
Conclusions:
- GSMs represent a novel class of compounds for reversing cancer MDR.
- GSM modulators offer a safer and potentially more effective approach to treating drug-resistant cancers.
- Further research into GSM-based therapies is warranted for clinical translation.

Homogeneous Equilibria for Gaseous Reactions
For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar concentrations (Kc) or partial pressures (Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity. According to the ideal gas equation:

Respiration and Gaseous Exchange
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves...
