Endogenous Bioelectrical Modulation of Longevity-Associated and Inflammatory Signaling Pathways in Human Dermal...

Area of Science:

• Cell Biology
• Biophysics
• Dermatology

Background:

• Tissue aging involves chronic inflammation, impaired microvascular support, and cellular dysfunction.
• Dermal fibroblasts regulate key aging processes like cytokine signaling, redox balance, and extracellular matrix homeostasis.
• Endogenous bioelectrical activity is increasingly recognized for its potential to influence cellular functions and regulatory pathways.

Purpose of the Study:

• To investigate the molecular effects of Radio Electric Asymmetric Conveyer Anti-Inflammatory Cellular Treatment delivered under Inside Blue Zone conditions (REAC ACT-IBZ) on human dermal fibroblasts (HFF1).
• To identify specific molecular changes induced by REAC ACT-IBZ exposure in relation to cellular aging and inflammation.

Main Methods:

• Human dermal fibroblasts (HFF1) were subjected to nine standardized REAC ACT-IBZ treatment sessions.
• Molecular changes were assessed using quantitative real-time PCR (RT-qPCR), ELISA, and immunofluorescence analysis.
• Semi-quantitative fluorescence intensity assessment supported the immunofluorescence findings.

Main Results:

• REAC ACT-IBZ exposure led to increased expression of SIRT1 and Vascular Endothelial Growth Factor (VEGF).
• Transcriptional modulation of cytokine-related genes (IL-1α, IL-1β, IL-2, IL-8) was observed.
• Immunofluorescence indicated increased FOXO1 and SIRT1 staining and reduced mTOR staining in treated cells.

Conclusions:

• REAC ACT-IBZ exposure in human dermal fibroblasts is associated with a distinct molecular profile.
• This profile includes modulation of stress-response regulators, angiogenesis signaling, and specific cytokine-related genes.
• The findings suggest that endogenous bioelectrical modulation may interact with molecular networks crucial for tissue homeostasis and inflammaging.
