Yegorov1,2* Possible Role of Autophagy Activation in Stimulation of Regeneration 1Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, Moscow, 119991 Russia2Moscow Institute of Physics and Technology (State University), Dolgoprudny, 141700 Russia 3Koltzov Institute of Developmental Biology, Russian Academy of Sciences, Moscow, 119991 Russia *yegorov58@gmail.com Received - 2013-02-26; Accepted - 2013-03-25 Human cell aging is irregular. Senescent cells often impair the function of their neighbour nonsenescent cells. Stimulation of tissue regeneration is of potential applied significance for medicine, in particular, for geriatrics. One of the possible ways to induce regeneration consists of a selective removal of senescent and damaged cells from the tissue. Studies of the mechanism of action for Satura Rosta Balm, which stimulates the hair growth, showed that the balm does not stimulate proliferation of various human cells, nor does it improve the cell resistance to stress. Oppositely, the balm exerted a cytotoxic effect in oxidative stress without increasing the production of reactive oxygen species. Further investigations show that the balm increases the transcriptional activity of the p53 gene, activates autophagy, and induces weak adipogenic differentiation. A hypothesis of autophagic regeneration is discussed, suggesting that selective autophagic death of senescent and damaged cells, which experience oxidative stress, triggers regeneration, which may be stimulated by both a rejuvenating effect of an increase in autophagy and a release of additional metabolites. autophagy, proliferation, hair, hair loss, human cells, SaturaR Rosta, regeneration |
