Gasotransmitters: growing pains and joys

Area of Science:

• Biochemistry
• Molecular Biology
• Physiology

Background:

• Gasotransmitters are endogenous gaseous signaling molecules with critical biological roles.
• The known gasotransmitter family includes nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S).
• Significant challenges remain in understanding gasotransmitter interactions and their cellular signaling networks.

Purpose of the Study:

• To review the current understanding of gasotransmitters.
• To propose ammonia and methane as potential new gasotransmitters.
• To stimulate further research into the gasotransmitter signaling network.

Main Methods:

• Literature review and conceptual analysis.
• Evaluation of ammonia and methane against gasotransmitter criteria.
• Discussion of future research directions.

Main Results:

• Ammonia meets the established criteria for a gasotransmitter.
• Methane is presented as another plausible candidate gasotransmitter.
• The study highlights the need for further investigation into these potential new members.

Conclusions:

• The gasotransmitter family may be larger than currently recognized.
• Further research is essential to elucidate the roles of ammonia and methane.
• Expanding the gasotransmitter repertoire will deepen our understanding of cellular signaling.
