Hypothalmus - Role in Aging and longevity

The hypothalamus is a small structure in the brain which is involved in important physiological functions including homeostasis and systemic energy balance, which support health and longevity. Recent research indicates that the neural stem cells found within hyopathalamus may be key to slowing the aging process. However, this not through neurogenesis, but by the secretion of exosomes and microRNA content. (1) Exosomes are vesicles released by the stem cells into the cerebrospinal fluid. Exosomes are an important mechanism for cell-to-cell communications. communication. The content of exsomes include microRNAs, which modifies the expression of genes in the recipient cell.

 

Inflammation and the Hypothalamus

Longevity of Hypothalamus Neural Stem Cells (Hnsc). With aging there is a significant increase in inflammation, which negatively affects the pool of neural stem cells in the hypothalamus, decreasing their numbers, thereby reducing release of exosomes and microRNA. Most importantly, microRNAs slows aging by inhibiting inflammatory gene expression, thereby improving health of the hypothalamus (3). In experimental animals, the start of aging in the animals began with the loss of hypothalamus stem cells.(4)

  • INFLAMMATION.  Negatively impact the viability (number) and function of stem cells and astrocytes. Astrocyte are the most abundant glial cells in the brain and support synaptic transmission and electrical impulses. Astrocytes are vital to the function of the hypothalmus.(2)
  • CORTISONE. The stress hormone cortisone also destroys Hnsc cells.

Yellows - Activating FOXO Longevity Factors and Longevity Pathways

It is known that the activation of FOXO transcription factors promote extreme longevity, which has been demonstrated in research animals as well as in animals such as the multi-cell animal hydra. In  human longevity, those with gene variants which activate higher levels of FOXO are also the longest lived with least amounts of illness and disease.

Despite years of research declaring that antioxidants, such as vitamins C and E, promoted longevity, none have been shown to activate the longevity factors FOXO or Nrf2. Rather, potent longevity factor activation has been shown by many plant based flavonoids. (1) Flavonoids are yellow in nature, and the word is derived from the latin flavus, which means yellow.

 

  • FLAVONOIDS - APGEININ & LUTEOLIN
  • In a comprehensive study comparing flavonoids to antioxidative vitamins, determined that flavonoids are very potent activators of longevity factors, versus antioxidants. Antioxidants, including Vitamin C and E, did not trigger activation of any longevity factors.
  • The flavonoids Apigenin and Luetolin were shown to be the most active longevity triggers of the flavonoids tested.
  • Apigenin and Luteolin highly activate Nrf2, FOXO and PPARγ.
  • EGCG (Green Tea)  - Life extending properties include upregulation of DAF-16 (the longevity factor equivalent to FOXO) and endogenous superoxide dismutase (SOD),
  • ICARIIN (Epimedium) - Inihibits the pathway ISS (Insulin Signaling) which causes an activation of DAF-16 (analogous to FOXO). Also facilitates genome stability by reducing the DNA strand breaks.
  •  MYRICETIN (Bayberry extract) - A longevity enhancing and mitochondrial activating flavonoid. Mitichondria activation improves respiration, endurance and activity levels by increasing the density of mitochondria. Myricetin positively impacts cellular mitochondria through activating PGC-1α and SIRT1. SIRT1 is believed to play a major role in mitochondrial biogenesis and mitophagy (mitichondrial turnover).3

 Other FOXO Activators and Longevity Pathways:

  • TETRAHYDROCURCUMIN - A metabolite of curcumin, tetrahydrocurcumin has unque anti-aging properties including the activation of FOXO. In aging studies using Drosophila melanogaster , tetrahydrocurcumin extended the lifespan, by the involvement of both longevity factors FOXO and Sir2.
  • CURCUMIN -  Increases lifespan in laboratory animals by affecting age-related genes. Enhances gene expression of endogenous antioxidant system, increasing superoxide dismutase (SOD) and reducing lipid peroxidation.

Vision Longevity - Activating Nrf2 in the Retina by Lutein Zeaxanthin and Meso zeaxanthin

It has been well studied that the carotenoids lutein and zeaxanthin play an important role in preserving eye function by directly acting as antioxidants. However, new research indicates that these powerhouses go one important step further. This is through the activation the Nfr2 antioxidant defense network.

Nrf2 is a latent protein in the cell, that when activated, becomes a powerful transcription factor that turn on the Antioxidant Response Element (ARE). ARE is the master antioxidant switch in the cell and provides overwhelming antioxidant response, including increased levels of the potent cellular protector glutathione.

LUTEIN ZEAXANTHIN and MESO ZEAXANTHIN act as both direct antioxidants and as Nrf2 activators. Significantly, this makes their protection capacity for the retina significantly greater than only acting as an antioxidant. Implications of this include more capacity to slow the aging of the eye and preserve vision with aging. 

NRF2 CELLULAR PROTECTION:

  • Nrf2 Increases Glutathione Levels in Retina - Glutathione reduces toxic and age accelerating lipid and protein peroxidation in retina.
  • Mitigates Oxidative Stress. Oxidative stress is a significant factor in the disease initiation and progression of AMD (Age Related Macular Degeneration) and other diseases of the eye. Therefore, lutein, zeaxanthn and meso zeaxanthin which significantly mitigate oxidative stress, may aid in the prevention of AMD.
  • Mitigates Inflammation of the retina. Oxidative Stress activates Inflammation pathways in the retina which becomes chronic is eye diseases.
  • Meso zeaxanthin has been shown in research studies to have especially strong anti-inflammation potential.

Cardiac Aging - Heart Failure and Limits of Longevity

While we live in an age where people are living longer, an important limiting factor on longevity is the ability of the heart to maintain function.  Known causes of death for the oldest people on record (over 110 years old) were recorded as heart failure. Heart failure is due to the gradual loss of cardiomyocytes (heart muscle cells) and the increase in scarring of the heart muscle. The process may take place due to low grade inflammation of the muscle, which progresses with age, or injury (such as a heart attack) which may cause a more sudden loss of heart function. Inflammation in  the cardiovascular system is common with the aging process, being the result of hypertension, high blood glucose, trigylcerides, or oxidized VDL cholesterol.

Cardiac Aging Characteristics:

  • Increased injury and loss of cardiac muscle due to inflammation and injury,
  • Increased fibrosis and scarring of heart muscle
  • Loss of regenerative ability (cardiomyocytes)
  • Loss of cardiomyocyte homeostasis
  • Reduction in contractile strength of myocytes
  • Increased thickening of muscle (cardiac hypertrophy) - commonly caused by hypertension
  • Diabetes accelerates aging of the heart muscle, and is directly causative of cardiomyopathy - a damaging condition of the heart muscle which leads to heart failure.

Key Conditions of the Aging Heart

  • Atrial Fibrillation
  • Heart Failure (1)
  • Heart failure is primarily the result of insufficient ability to regenerate heart tissue by cardiomyoctes and the replacement of muscle with scar tissue.

 

  • Inhibiting Cardiac Fibrosis and Inflammation supports maintenance of Heart Function with aging.
  • Atrial fibrillation. Changes to the heart through aging, alters the ability of the left atrium to properly conduct the critical electrical impulses, which can cause an abnormal heart beat. Atrial fibrillation results from increased fibrosis in the heart muscle and a remodeling of the heart muscle. Nrf2 activation, which is potently activated by sulforaphane and andrographolide, may reduce fibrosis. 
  • Cardiomyocyte Regeneration and Maintenance (Homeostasis) - Mammal adult heart cells display very poor regenerative ability after incurring inflammation or injury. Instead of regenerating, hearts undergo extensive scarring - reducing functional ability. In order to properly regenerate, there must be a proliferation of cardio myocytes. Hypertension can result in increased cellular death of the cardiomyocytes. An extract of epimedium (icariin) may mitigate the loss of heart muscle due to hypertension.(12) Furthermore, as demonstrated in lab animals, curcumin also may prevent loss of cardiac muscle due to myocardial infarction (heart attack).(16)
  • Cardiomyocyte homeostasis ensures that the heart muscle stays healthy and strong. Cardiac aging leads to a gradual loss of homeostasis, which leads to the death of the cardiomyocyte and eventual heart failure. An important mechanism for maintaining homeostasis is regulated autophagy in the cardiomyocyte. Autophagy eliminates defective proteins and recycles components into new structures.
  • Cardiac scarring is the development of fibrosis in response to an attempt to repair damaged tissue (including inflammation and heart attack). Fibrosis can be reduced by nrf2 activation.
  • Cardiac hypertrophy - is the result of scarring which eventually can lead to cardiac failure. Andrographolide and arjuna have been shown in lab research to inhibit hypertrophy.(2)
  • Contractibility of Cardiomyocytes. Healthy cardiomyocytes have strong contraction capability which may be loss with age and is  factor in heart failure. Luteolin can improve contraction and ameliorate myocardium fibrosis which may improve heart failure.
  • Reducing Myocardial Damage. Carnosic Acid may reduce myocardial damage through properties of anti-inflammatory and antioxidant effects on the heart.(9)
  • Chronic Inflammation - Coronary Artery Disease. Coronary artery disease creates conditions of pervasive inflammation which also affect the heart. Lutein is not only important for vision health, but has potent anti-inflammatory effect in coronary artery patients.(4)
  •  Nrf2 for Oxidative Homeostasis - Aging results in lower levels of nrf2. As a master antioxidant factor, nrf2 is essential to maintain homeostasis of a protective oxidative state for the heart. Increased nrf2 may also protective against cardio fibrosis.

 Natural support for Cardio Anti-aging

  • Terminalia Arjuna (bark extract) - Indian medicine has long recognized arjuna as a cardio tonic and now modern research is supporting this. In young fitness participants, an arjuna extract significantly improved cardiovascular strength and efficiency. Arjuna has also shown potential benefit in heart failure in research animals.(5)
  • Terminalia Arujuna - supports heart function in diabetic rats. Myocardium function improved, as hypothesized by the study researchers, as a result of increased in endogenous antioxidant enzymes.(17)
  • Benefits of Terminalia Arjuna:
    • Improved Diabetic heart function
    • Improved exercise capacity via cardiovascular efficiency
    • Strong improvement of left ventricle output in individuals with cardiovascular ailments.
    • Reduction in mass of cardiac hypertrophy
    • May have beneficial effects on pulmonary hypertension - which is a fatal disease characterized by right ventricular hypertrophy and right heart failure.(20)
    • Protection of cardiac muscle from injury
    • Cardio tonic effect - i.e. positively affecting heart function
  •  Apigenin - Provides supports for hypertrophy and diabetic cardiomyopathy.(2.3)
  •  Luteolin - Supports improved heart muscle contraction in lab animal models of heart failure.(4) Furthermore, in research simulated myocardial infarction (heart attack), luteolin increased autophagy of the heart muscle, increasing mitochondrial biogenesis, thereby lessening subsequent cardiac dysfunction.
  •  Icariin (Epimedium) - helps mitigate hypertension induced cellular death of the   cardiomyocytes.(12)
  •  Lutein - Provides powerful anti-inflammatory action in cardiovascular disease, thereby reducing potential for fibrosis. Lutein is further supportive by acting as an nrf2 activator.  
  • Sulforaphane - Inhibits diabetic cardiomyopathy via the effects as a powerful Nrf2 activator.(13) Experimental research has shown that sulforaphane inhibited cardiomyopathy in both type 1 and type 2 diabetes. In experimental models of cardiac infarctions (heart attack), sulforaphane inhibited changes to the heart muscle, in particular the fibrosis that occurs post-injury.(23)
  • EGCG (Green Tea Extract) - Has an inhibitory effect on myocardial fibrosis.(14)
  • Andrographolide - Nrf2 activator, significantly reducing oxidative stress and potent ant-inflammation agent.(15, 22) Also upregulates glutathione levels in cardiomyocytes, which offers powerful protection against oxygen deprived injury (such as a myocardial infarction). (21) 
  • Curcumin - Regulates autophagy of cardiomyocytes, which supports the degradation and recycling of cardiomyocyte components, such as mis-folded proteins. Autophagy is an essential process in supporting cardiomyocyte homeostasis. When autophagy is dysregulated, the muscle cell dies and may lead to atrophy of the heart and eventually heart failure. In addition to curcumin, resveratrol and berberine also regulate autophagy,(18)

      Prevention of Lipid Oxidative Damage and Anti-Inflammation - Lutein Zeaxanthin Mesozeaxanthin

      Protective macular pigments consist of lutein, zeaxanthin and meso zeaxanthin which act as powerful lipid antioxidants as well as functioning as an anti-inflammatory in the retina. In both the retina and the brain, these pigments are readily absorbed into the cellular membranes and orient themselves perpendicular in the membrane which acts to stabilize the cellular membrane.(1) The cellular membrane is made from unsaturated fats, which are very susceptible to free radical induced oxidative damage by high energy short wave light (such as blue light). As a potent lipid antioxidants, lutein, zeaxanthin and meso zeaxanthin signifcantly boost protection of the cellular membrane, and thereby protecting cells of the retina cells and neurons in the brain.(2)

      • All three xanthophylls function as potent lipid anti-oxidants and demonstrate anti-inflammation in both the retina and brain.
      • Offers protective effect of lipid cellular membrane of retina and neuron cells.
      • Offers potential protective role in diabetic retinopathy.(3)
      • Serum levels of macular xanthophylls are significantly lower in diabetic retinopathy subjects.(4)
      • Meso zeaxanthin increases antioxidant protection in retina be enhancing density of macular pigment.
      • Meso zeaxanthin has been shown to be the strongest xanthophyll antioxidant.
      • Meso zeaxanthin is required to obtain maximum antioxidant effect in the retina.(6)
      • Meso zeaxanthin is also radioprotective. In research conducted with laboratory animals, meso zeaxanthin was shown to reduce radiation induced-damage in mice, including reduction in DNA damage. (7)

        Sulforaphane and Prostate Cancer - the role of Non-Coding RNA

        New biomarkers have been identified that may help in the early diagnosis and treatment of prostate and urological cancers.  Long non-coding RNA (Ribonucleic Acid), a form of RNA not involved in cellular protein encoding, are altered in these cancers.(1,2)

        Expression of long non-coding RNA is believed to play a significant role in the initiation and progression of prostate cancer. Sulforaphane has been found to inhibit the expression of  non-coding RNA associated with prostate cancer. Researchers conclude that sulforaphane may prevent and suppress prostate cancer by the inhibition of key non-coding forms of RNA. (3)

        Brown Adipose Tissue - Obesity Benefits of Glucoraphanin and Pterostilbene

        Energy generation from brown adipose tissue (thermogenesis) is important for maintaining longevity, reducing obesity and supporting energy homeostasis. Brown adipose tissue (BAT) is central to physiological energy homeostasis. Enhancing brown adipose tissue reduces obesity, diabetes, insulin resistance and non-alcoholic fatty liver..

        BAT dissipates energy in the form of heat through increased theromgenesis.(1) Browning of white adipose tissue, which converts characteristics of white adipose tissue to brown adipose tissue, increases expression of the thermogenic mitochondrial protein UCP-1. The uncoupling protein 1 (UCP-1) is a potent protein which shifts energy from ATP to heat.

        Greater amounts of brown adipose tissue and the thermogenic capacity of the tissue are indicative of youth. With age, brown adipose tissue is decreased, while white adipose tissue becomes predominant and accelerates aging via inflammation and insulin resistance. .

        GLUCORAPHANIN - Is a precursor of sulforaphane. 
        In laboratory mice fed a high fat diet, glucoraphanin supplementation promoted increased energy expenditures via an increase in UCP-1 protein expression in adipose deposit areas. Furthermore, results included decreases in weight, increased insulin sensitivity and improved glucose tolerance.(2)

        PTEROSTILBENE - Studied in obese rats, pterostilbene increased the thermogenic capability of the BAT through an upregulation of Ucp1 protein expression..(3)
