About Pinealon

Pinealon is a short regulatory peptide with the amino acid sequence Glu-Asp-Arg, originally isolated from the pineal gland extract Epithalamin by researchers at the Saint Petersburg Institute of Bioregulation and Gerontology. Classified as a bioregulatory peptide, Pinealon belongs to a family of short peptides studied by Khavinson and colleagues for their ability to interact with specific DNA sequences and modulate gene expression without receptor mediation. Research published in the Bulletin of Experimental Biology and Medicine demonstrates that Pinealon penetrates cell membranes and nuclear envelopes, reaching the nucleus where it binds complementary DNA sites and influences transcription of genes involved in neuronal differentiation and neuroprotection. Studies in cortical neuron cultures show that Pinealon increases cell viability under hypoxic and toxic conditions by modulating expression of genes related to apoptosis, antioxidant defense, and signal transduction. Scientists utilize Pinealon to investigate peptide bioregulation of CNS function, epigenetic mechanisms of short peptides, and potential neuroprotective strategies in aging and neurodegeneration research.
