Gender and age peculiarities of autophagy in men and women induced by a comprehensive wellness program: a prospective observational study

Abstract

Background. Autophagy refers to an evolutionary physiological mechanism of cell self-purification. The use of its positive effects in regenerative and preventive medicine implies this process to be investigated under the conditions of various therapeutic factors.Objective. To investigate the influence of gender, age and somatic-morphological factors on the autophagy processes induced by a comprehensive wellness program as expressed by the marker protein Beclin-1.Methods. A prospective observational study involved 107 patients to be monitored before and after comprehensive wellness procedures. All study participants underwent a wellness program in the clinic of OOO Centr Zdorovie (Maykop, Russia). The study was conducted in the periods of September‒December 2020 and January 2021. The study involved measuring the concentration of Beclin-1 protein in the blood before and 12 days after the wellness procedures. In order to characterize the degree of activation of the autophagy process, the index “delta-Beclin-1” was introduced (difference between the initial level of Beclin-1 protein concentration and the level registered after 12 days). The autophagy response was evaluated in terms of its upward or downward direction (positive/negative delta- Beclin-1 value, respectively). The effect of the comprehensive wellness procedures on the functional systems of the organism was determined in accordance with the laboratory tests (complete blood count, lipid profile), morphometric evaluation, and the assessment of body composition by impedance monitoring. The obtained data were processed using SPSS Statistics 26.0 (IBM, USA).Results. Monitoring of Beclin-1 protein concentration revealed that basic autophagy activity is age-specific and significantly lower in individuals over 60 years as compared to both individuals under 60 years and healthy persons. This correlation with age appears more pronounced in obese individuals (r = -0.59). The basic activity of autophagy in men was 30% lower than in women, however, after a set of wellness procedures the mentioned response in men increased by 7%. The study found that not all patients responded unidirectionally to the comprehensive wellness procedures: 49 out of 77 patients showed an increase in Beclin-1 protein concentration, while 28 — a decrease. Patients who participated in the wellness program demonstrated negative correlation between the level of Beclin-1 protein expression and age, while those responding with an increase in Beclin-1 protein level — with body mass index, weight and fat mass. The source of autophagy activity in men under 60 years can refer to fat mass, and in women — lean body mass, especially in the mature age of period II (36‒60 years).Conclusion. The factors of basic autophagy and autophagy induced by the complex of wellness procedures include age, gender and body weight. These factors obtain different significance at different age periods. A comprehensive wellness program can serve as an alternative to existing pharmacological methods for activating autophagy in humans.
