Resolutive Treatment of Actinic Keratosis through Peptides Extracted from Zebrafish Conveyed Across Laser-assisted Transcutaneous Delivery (Cryopass Therapy)

Introduction: Actinic keratoses (AKs) are humans' most common keratinocyte- derived precancerous lesions. They can be observed predominantly in fair-skinned individuals on sun-exposed surfaces. Another name for AKs is solar keratosis. The primary risk factor for AKs is cumulative UV exposure from sunlight and/or tanning salons. AKs may present on a patient as a few detectable lesions. Clinically, they present as scaly erythema lesions with various pigmentations. Surgery treatment is the only approach that can definitively resolve the illness. Methods: The research aims to demonstrate the effectiveness of treating relapsing AKs through the use of factors present during organogenesis extracted from zebrafish caviar conveyed through a cryopass therapy device (cryolaser phoresis). These factors are peptides present during specific phases of organogenesis and have shown the capacity to reverse cancer and neurodegeneration processes through gene, transcriptional, translational, and post-translational regulation. Results: We found that 90% of patients responded. The percentage of responding patients was 100% among females and 80% among men. Conclusion: Our results confirm previous findings about the effectiveness of stem cell differentiation stage factors (SCDFs) in cancer and open new ways to integrate treatment.
