Alterations in postmenopausal plasmatic lipidome.

Area of Science:

• Biochemistry
• Metabolomics
• Women's Health

Background:

• Menopause (typically 40-50 years) causes health issues like metabolic disturbances and increased cardiovascular disease risk.
• Classic methods may miss subtle lipid alterations during this transition.
• Investigating lipidomic changes is crucial for understanding menopause's health consequences.

Purpose of the Study:

• To identify specific lipid alterations not detected by conventional methods in post-menopausal women.
• To explore the relationship between these lipid changes and metabolic markers.

Main Methods:

• Serum lipid profiles of 40 pre- and post-menopausal women were analyzed.
• A lipidomic approach utilizing mass spectrometry was employed.
• Metabolite concentrations and correlations with clinical markers were assessed.

Main Results:

• Significant increases (over 25%) in certain lipid species were observed post-menopause.
• Ceramides (N.C23:0.Cer, N.C23:0(OH).Cer, N.C24:0(OH).Cer) showed notable fold changes (1.68-1.58).
• 14 metabolites, especially ceramides, differed significantly; correlations with glucose and lipid markers were identified.

Conclusions:

• Post-menopause is associated with distinct lipid alterations, particularly in ceramides.
• These lipid changes correlate with key glycidic and lipid metabolic markers.
• Findings may aid future research into menopause-associated diseases.
