Hydrogen sulfide as a potent cardiovascular protective agent

Area of Science:

• Biochemistry
• Physiology
• Cardiovascular Science

Background:

• Hydrogen sulfide (H2S) is an endogenous gasotransmitter synthesized from l-cysteine.
• Key enzymes involved include cystathionine-γ-lyase (CSE), cystathionine-ß-synthase (CBS), and 3-mercaptopyruvate sulfurtransferase (3-MST).
• CSE is the primary H2S-producing enzyme in the cardiovascular system.

Purpose of the Study:

• To review the physiological functions of H2S.
• To summarize H2S's protective role in cardiovascular diseases.
• To explore potential therapeutic benefits of H2S for cardiovascular conditions.

Main Methods:

• Literature review of existing research on H2S.
• Analysis of H2S synthesis pathways and enzymatic actions.
• Examination of H2S's impact on cardiovascular disease mechanisms.

Main Results:

• H2S acts as the third gasotransmitter, alongside nitric oxide (NO) and carbon monoxide (CO).
• H2S regulates vasodilation, angiogenesis, inflammation, oxidative stress, and apoptosis.
• H2S demonstrates protective effects against cardiovascular diseases via vasorelaxation, inhibiting remodeling, and preventing foam cell formation.

Conclusions:

• H2S has significant physiological functions in the cardiovascular system.
• H2S offers protective benefits against major cardiovascular diseases.
• Further understanding of H2S can lead to novel therapeutic strategies for cardiovascular diseases.
