[Method for endogenous formaldehyde evaluation in animal organism].

Area of Science:

• Biochemistry
• Analytical Chemistry
• Toxicology

Context:

• Endogenous formaldehyde (FA) is a reactive molecule involved in various biological processes, but its precise quantification in vivo remains challenging.
• Current methods for FA detection may lack specificity or sensitivity, hindering accurate assessment of FA metabolism.
• Understanding FA levels is critical for research in neurobiology, toxicology, and metabolic disorders.

Purpose:

• To develop and validate a novel, sensitive fluorescence-based method for quantifying endogenous formaldehyde (FA) in biological samples.
• To assess the reliability of the developed method using rat models with modulated FA metabolism.
• To establish a robust tool for studying FA dynamics in physiological and pathological conditions.

Summary:

• A new method utilizes dimedone to form a stable complex with FA, which is then quantified using fluorescence analysis.
• The method was successfully applied to rat models, demonstrating its ability to detect changes in FA levels following administration of FA, methylamine (SSAO substrate), or semicarbazide (SSAO inhibitor).
• Measured FA concentrations in rat liver tissue showed significant differences across treatment groups, validating the method's effectiveness.

Impact:

• Provides a reliable and sensitive analytical tool for endogenous formaldehyde quantification in biomedical research.
• Facilitates further investigation into the role of formaldehyde in cellular processes and disease pathogenesis.
• Enables more accurate studies of formaldehyde metabolism and the effects of substances that modulate its levels.
