CONTEXT: In India, vaidyas (Ayurvedic physicians) traditionally administer triphala and its constituents as therapeutic agents for promoting digestion and satiety. OBJECTIVE: The research team performed the present study to investigate the effects of triphala and its constituents (T bellirica [bibhitaki], T chebula [haritaki], and E officinalis [amalaki]) on the dietary induction of obesity (diet-induced obesity [DIO]), and other symptoms of visceral obesity syndrome, in mice fed a high-fat diet (HFD).

SIRT1 (sirtuin 1) is the human ortholog of the yeast Sir2 (silent information regulator 2) protein, which is implicated in lifespan extension in model organisms, such as yeast, worms and flies. It is an NAD+-dependent protein deacetylase with over two dozen known substrates that affect a wide variety of cellular processes, ranging from metabolism, cell cycle, growth and differentiation, inflammation, senescence, apoptosis, stress response and aging.

A recent report of virtually complete protection from diabetes and cancer in a population of people with hereditary dwarfism revived interest in elucidating the relationships between growth, adult body size, age-related disease and longevity. In many species, smaller individuals outlive those that are larger and a similar relationship was shown in studies of various human populations. Adult body size is strongly dependent on the actions of growth hormone (GH) and the absence of GH or GH receptor in mice leads to a remarkable extension of longevity.

BACKGROUND: Observational studies have demonstrated similarities between the underpinning of frailty and biological features of centenarians, suggesting that adaptability to age-related multiple physiological decline may be a core component of successful aging. The aim of this study is to determine whether hormonal pathways potentially involved in energy homeostasis contribute to survival beyond 100 years of age.

Adipose tissue engineering has recently gained significant attention from materials scientists as a result of the exponential growth of soft tissue filler procedures being performed within the clinic. While several injectable materials are currently being marketed for filling subcutaneous voids, they often face limited longevity due to rapid resorption. Their inability to encourage natural adipose formation or ingrowth necessitates repeated injections for a prolonged effect and thus classifies them as temporary fillers.

Excess adipose tissue is associated with metabolic disease and reduced life span, whereas caloric restriction decreases these risks. Here we show that as mice age, there is downregulation of Dicer and miRNA processing in adipose tissue resulting in decreases of multiple miRNAs. A similar decline of Dicer with age is observed in C.†elegans. This is prevented in both species by caloric restriction. Decreased Dicer expression also occurs in preadipocytes from elderly humans and can be produced in cells by exposure to oxidative stress or UV radiation.

Studies in mutant, gene knock-out and transgenic mice have demonstrated that growth hormone (GH) signalling has a major impact on ageing and longevity. Growth hormone-resistant and GH-deficient animals live much longer than their normal siblings, while transgenic mice overexpressing GH are short lived. Actions of GH in juvenile animals appear to be particularly important for life extension and responsible for various phenotypic characteristics of long-lived hypopituitary mutants.

Interactions between genetic (genome) and environmental factors (epigenome) operate during a person's entire lifespan. The aging process is associated with several cellular and organic functional alterations that, at the end, cause multi-organic cell failure. Epigenetic mechanisms of aging are modifiable by appropriate preventive actions mediated by sirtuins, caloric input, diet components, adipose tissue-related inflammatory reactions, and physical activity.

Clinical Interventions in Aging

Obesity is a global epidemic associated with aging-like cellular processes; in both aging and obesity, resistance to hormones such as insulin and leptin can be observed. Leptin is a circulating hormone/cytokine with central and peripheral effects that is released mainly by subcutaneous white adipose tissue. Centrally, leptin controls food intake, energy expenditure, and fat distribution, whereas it controls (among several others) insulin sensitivity, free fatty acids (FFAs) oxidation, and lipolysis in the periphery.
