The Urge to Radical Life Extension

Those portions of the modern longevity community interested in bringing an end to aging and extending healthy human life span indefinitely tend to be the older portions, people who have been a part of the broader movement for quite some time. Newcomers tend to be more moderate, aiming at lesser goals. Perhaps this is a result of the successful projects, such as the SENS Research Foundation and Methuselah Foundation, tending to moderate their rhetoric as they attract a broader and larger base of support. I think that this road to moderation might be a problem, and that there is thus a continued role for those who loudly declaim that the goal is to control aging absolutely, via new medical technology, and that the natural consequence of that control is healthy, active, youthful life that extends for centuries or more. If the goals that our movement works towards are broadly watered down from radical life extension of centuries to just adding a few more years, then marginal projects that can do no more than add a few more years will come to dominate the field to the exclusion of everything else. We are already more or less in this situation, in that that the vast majority of funding goes towards discovery and development of small molecules that tinker with the operation of an aged metabolism to make it a little more resilient to the underlying causes of aging. If that is all that is done, then we'll all age and die on basically the same schedule as our parents and grandpa...

In this study, we determine whether transient reintroduction of embryonic stem cell cycle miR-294 promotes cardiomyocyte cell cycle reentry enhancing cardiac repair after myocardial injury. A doxycycline-inducible AAV9-miR-294 vector was delivered to mice for activating miR-294 in myocytes for 14 days continuously after myocardial infarction. miR-294-treated mice significantly improved left ventricular functions together with decreased infarct size and apoptosis 8 weeks after MI. Myocyte cell cycle reentry increased in miR-294 hearts parallel to increased small myocyte number in the heart. Isolated adult myocytes from miR-...

This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

In conclusion, we found a gradient of increasing blood pressure with higher levels of BMI. The fact that this gradient is present even in the fully adjusted analyses suggests that BMI may cause a direct effect on blood pressure, independent of other clinical risk factors. PRRX1 as a Possible Point of Control for Remyelination https://www.fightaging.org/archives/2018/12/prrx1-as-a-possible-point-of-control-for-remyelination/ Researchers here outline what is possibly a new point of intervention in the processes that maintain the myelin sheath that wraps nerves. This sheath is vital to the correct operatio...

In this study, we found that TNF-α resulted in an impairment of autophagic flux in microglia. Concomitantly, an increase of M1 marker expression and reduction of M2 marker expression were observed in TNF-α challenged microglia. Upregulation of autophagy via serum deprivation or pharmacologic activators (rapamycin and resveratrol) promoted microglia polarization toward M2 phenotype, as evidenced by suppressed M1 and elevated M2 gene expression, while inhibition of autophagy with 3-MA or Atg5 siRNA consistently aggravated the M1 polarization induced by TNF-α. Moreover, Atg5 knockdown alone was suffic...

This study suggests that exocrine glands can be induced from pluripotent stem cells for organ replacement regenerative therapy. Replacement of Aged Microglia Partially Reverses Cognitive Decline in Mice https://www.fightaging.org/archives/2018/10/replacement-of-aged-microglia-partially-reverses-cognitive-decline-in-mice/ Researchers here report on a compelling demonstration that shows the degree to which dysfunctional microglia contribute to age-related neurodegeneration. The scientists use a pharmacological approach to greatly deplete the microglial population and then allow it to recover naturally. The...

In this study, we found that TXNIP deficiency induces accelerated senescent phenotypes of mouse embryonic fibroblast (MEF) cells under high glucose condition and that the induction of cellular ROS or AKT activation is critical for cellular senescence. Our results also revealed that TXNIP inhibits AKT activity by a direct interaction, which is upregulated by high glucose and H2O2 treatment. In addition, TXNIP knockout mice exhibited an increase in glucose uptake and aging-associated phenotypes including a decrease in energy metabolism and induction of cellular senescence and aging-associated gene expression. We propose that...

It is not unusual in Alzheimer's care settings for dementia patients to seek constant attention. What can you do to alleviate this problem?By Bob DeMarcoAlzheimer's Reading RoomI received this via email from our Reader Brian.Hi Bob! I have been reading you posts on the Alzheimer's Reading Room for some months now and find them very informative and uplifting.I have been caring for my mother for just over 6 months now who was diagnosed with Alzheimer's about 2 years ago, even though I and other members of our extended family suspect she had it a lot longer.To be honest with you,I find caring for her very tiring and weary som...
