[The influence of AEDG and KE peptides on mitochondries stain and L7A ribosomes protein expression during human pineal gland and thymus cell senescence in vitro.]
Abstract
It was verified new molecular targets of geroprotective activity of AEDG (epitalon) and KE (vilon) peptides by the method of confocal laser scanning microscopy. It was shown that the MitoTracker Red mitochondries staining decreased and L7A ribosomal protein synthesis compensatory increased during pineal and thymic cell senescence in vitro. AEDG peptide increases in 1,5 times the square of MitoTracker Red mitochondries staining and decreases on 22% the expression of ribosomal protein L7A in cultures of human pineal gland cells during its senescence. KE peptide increases in 1,5 times the square of MitoTracker Red mitochondries staining and decreases on 15% the expression of ribosomal protein L7A in cultures of human thymic cells during its senescence. The square of MitoTracker Red mitochondries staining decreases and the expression of L7A ribosomal protein compensatory increases during pineal gland and thymic cells senescence. We can suppose that AEDG and KE peptides have a tissue-specific effect that normalizes the functions of mitochondria and ribosomes of pinealocytes and thymocytes.
