I. ХХІ ғасырдағы ұзақ өмір сүруді анықтау: көп қырлы перспектива
А. Өмірден тыс: Денсаулық сақтау туралы түсінік. Ұзақ өмір сүру, қазіргі заманғы дискурста, жай хронологиялық жасқа ұшырайды. Ол «Денсаулық сақтау қоры» түсінігін қамтиды – денсаулығыңыз жақсы, едәуір созылмалы аурулардан және функционалдық шектеулерден босатылған өмір сүру кезеңі. Бұл өзгеріс перспективада тек санды ғана емес, өмір сүрген жылдардың сапасын көрсетеді. Денсаулық сақтау қорына генетикалық бейімділік, қоршаған орта факторлары, өмір салтын таңдау және денсаулық сақтауға қол жетімділіктің күрделі интерфейсі әсер етеді. Денсаулықты өлшеу қиын, көбінесе суррогат маркерлеріне, көбінесе жасына байланысты аурулардың таралуы (жүрек-қан тамырлары аурулары, қатерлі ісік, нейроділігірім бұзылулар), функционалды сыйымдылық (ұтқырлық, танымдық қабілеттер) және жалпы әл-ауқат. Зерттеулер дәлірек және объективті шараларды, оның ішінде қартаюдың биомаркерлерін белсенді түрде зерттейді, соның ішінде денсаулық сақтауды жақсарту және бақылау.
В. Демографиялық ауысымдар: жаһандық халыққа сұрғылт. ХХІ ғасыр бүкіл әлемде қартайған халықтың бұрын-соңды болмаған демографиялық өзгеруіне куә болып табылады. Медицина, санитария және тамақтану саласындағы жетістіктер, әсіресе дамыған елдерде өмір сүру ұзақтығы күрт өсті. Бұл тұрғындардың бұл «сұрыптары» маңызды әлеуметтік және экономикалық қиындықтарды ұсынады. Медициналық қызметтерге, әлеуметтік қамсыздандыру жүйелерінің ұлғаюы, үлкен тәуелді халыққа байланысты әлеуметтік қамсыздандыру жүйелері және ықтимал еңбек тапшылығы – кейбір салдарлар. Халықтың қартаю динамикасын түсіну осы сын-қатерлерді азайту және тұрақты болашақты қамтамасыз ету үшін тиімді саясат пен стратегияны әзірлеу үшін өте маңызды.
C. Қартаю биологиясы: тетіктерді аша алмады. Ұзақ өмір сүруге ұмтылу қартаюды басқаратын негізгі биологиялық процестерді түсінумен тығыз байланысты. Қартаю – бұл жай ғана зақымның пассивті жинақталуы ғана емес, бірнеше өзара байланысты жолдармен күрделі, реттелетін процесс. Қартаюдың негізгі белдіктері:
1. **Genomic Instability:** The accumulation of DNA damage, mutations, and epigenetic alterations that compromise cellular function and integrity. This can lead to increased susceptibility to disease and accelerated aging. Research focuses on DNA repair mechanisms, telomere maintenance, and epigenetic modifications to combat genomic instability.
2. **Telomere Attrition:** The shortening of telomeres, protective caps on the ends of chromosomes, with each cell division. Critically short telomeres trigger cellular senescence or apoptosis, contributing to tissue dysfunction and aging. Strategies to maintain or extend telomeres are being explored as potential anti-aging interventions.
3. **Epigenetic Alterations:** Changes in gene expression patterns without altering the underlying DNA sequence. Epigenetic modifications, such as DNA methylation and histone modifications, play a crucial role in regulating cellular processes and can be influenced by environmental factors and aging. Targeting epigenetic alterations offers a potential avenue for reversing age-related changes in gene expression.
4. **Loss of Proteostasis:** The decline in the ability to maintain protein homeostasis, leading to the accumulation of misfolded and aggregated proteins. This can disrupt cellular function and contribute to age-related diseases such as Alzheimer's and Parkinson's. Enhancing protein folding, degradation, and clearance mechanisms is a key focus of aging research.
5. **Deregulated Nutrient Sensing:** Disruption of signaling pathways that regulate nutrient metabolism, such as insulin/IGF-1 signaling, mTOR signaling, and AMPK signaling. These pathways play a crucial role in regulating cellular growth, energy metabolism, and stress resistance. Modulation of these pathways through dietary interventions or pharmacological agents can potentially extend lifespan and healthspan.
6. **Mitochondrial Dysfunction:** Decline in mitochondrial function, leading to decreased energy production, increased oxidative stress, and impaired cellular respiration. Mitochondria play a critical role in cellular energy production and are particularly vulnerable to age-related damage. Enhancing mitochondrial biogenesis, function, and quality control is a promising strategy for combating aging.
7. **Cellular Senescence:** The accumulation of senescent cells, cells that have stopped dividing but remain metabolically active and secrete a range of pro-inflammatory factors. Senescent cells contribute to tissue dysfunction and age-related diseases. Selective removal of senescent cells (senolytics) or inhibition of their pro-inflammatory activity (senomorphics) is a rapidly developing area of aging research.
8. **Stem Cell Exhaustion:** Decline in the regenerative capacity of stem cells, leading to impaired tissue repair and maintenance. Stem cells play a crucial role in replenishing damaged or aged cells. Strategies to enhance stem cell function and prevent stem cell exhaustion are being explored.
9. **Altered Intercellular Communication:** Disruption of communication between cells, leading to impaired tissue homeostasis and systemic dysfunction. Intercellular communication is essential for coordinating cellular activities and maintaining tissue integrity. Restoring or enhancing intercellular communication is a potential therapeutic target for aging.
10. **Chronic Inflammation:** A persistent, low-grade inflammatory state that contributes to age-related diseases. Chronic inflammation, often referred to as "inflammaging," is driven by a complex interplay of factors, including senescent cells, gut dysbiosis, and immune system dysfunction. Reducing chronic inflammation is a key goal of anti-aging interventions.D. Қоршаған орта әсері: экспозиция және қартаю. Экспозиция барлық қоршаған орта туралы барлық экологиялық экспозицияларды олардың өмір бойы, перенатальды дамудан қартайғанға дейін қамтиды. Бұл экспозициялар, соның ішінде диета, өмір салты, ластаушы заттар және әлеуметтік факторлар қартаю процесіне айтарлықтай әсер етеді. Экспозимді түсіну және оның ұзақ өмір сүруге әсері салауатты қартаюға ықпал ету үшін жеке стратегияны әзірлеу үшін өте маңызды. Қартаюға әсер ететін ерекше экологиялық факторларға мыналар кіреді:

1. **Calorie Restriction (CR):** Reducing calorie intake without malnutrition has been shown to extend lifespan and healthspan in a wide range of organisms, from yeast to primates. CR appears to activate cellular stress response pathways, improve metabolic health, and reduce inflammation. While CR has shown promising results in animal studies, its feasibility and long-term effects in humans are still being investigated. Modified approaches, such as intermittent fasting, may offer some of the benefits of CR without the strict calorie restriction requirements.
2. **Intermittent Fasting (IF):** IF involves alternating periods of eating and fasting. Different IF protocols exist, including time-restricted feeding (TRF), alternate-day fasting (ADF), and 5:2 fasting. IF has been shown to improve insulin sensitivity, reduce inflammation, and promote cellular repair. Studies in humans have shown that IF can lead to weight loss, improved metabolic markers, and potentially increased longevity.

Metformin may activate AMPK, a key regulator of cellular energy metabolism. Clinical trials are investigating the potential of metformin to prevent age-related diseases in humans.
2. **Rapamycin:** An immunosuppressant drug, rapamycin inhibits mTOR, a signaling pathway involved in regulating cell growth, proliferation, and survival. Rapamycin has been shown to extend lifespan in various organisms. However, rapamycin can have significant side effects, limiting its potential for widespread use as an anti-aging drug.
