Resonating with Cellular Pathways: Transcriptome Insights into Nonthermal Bioeffects of Middle Infrared Light...

Area of Science:

• Biophysics
• Cell Biology
• Molecular Biology

Background:

• Middle infrared stimulation (MIRS) and vibrational strong coupling (VSC) are physical methods for biological regulation.
• Both MIRS and VSC utilize resonant mechanisms but have been rarely compared directly, especially at identical frequencies.
• Understanding their comparative bioeffects is crucial for advancing frequency-based biological interventions.

Purpose of the Study:

• To comparatively investigate the nonthermal bioeffects of MIRS and VSC on cell proliferation and migration.
• To explore these effects at an identical vibrational frequency (53.5 THz) corresponding to carbonyl vibrations.
• To elucidate the molecular mechanisms underlying these observed cellular changes.

Main Methods:

• Utilizing fibroblasts as cell-level models for proliferation and migration assays.
• Applying MIRS and VSC at a specific frequency (53.5 THz).
• Performing transcriptome sequencing to analyze gene expression changes.

Main Results:

• Both MIRS and VSC significantly increased fibroblast proliferation rates.
• Both MIRS and VSC notably enhanced fibroblast migration capacity.
• Transcriptome analysis revealed differential gene expression in pathways relevant to cellular functions.

Conclusions:

• MIRS and VSC exhibit comparable nonthermal bioeffects on fibroblast proliferation and migration at 53.5 THz.
• These physical stimuli induce changes at the molecular level, impacting cellular pathways.
• The findings provide evidence for synergistic nonthermal bioeffects and support the application of MIRS and VSC in frequency medicine.
