Novel mTOR Inhibitors Viewed as a Safer Option by Conservative Investors
The safest sort of investment into therapeutic development is one made in a part of a field that is well established, producing a small variant of an existing drug, using the well beaten path of small molecule development, targeting a mechanism that is very well understood, and that has extensive safety data associated with it. One could argue that mTOR inhibition is the canonical example of a low risk investment in the longevity field. Like most lower-risk exercises in medical development, the potential gain for patients is modest. mTOR inhibition can produce larger gains in mouse life span than exercise, but doesn't beat...

In this study, we tested a stem cell secretome product, which contains extracellular vesicles and growth factors, cytoskeletal remodeling factors, and immunomodulatory factors. We examined the effects of 4 weeks of 2×/week unilateral intramuscular secretome injections (quadriceps) in ambulatory aged male C57BL/6 mice (22-24 months) compared to saline-injected aged-matched controls.
Secretome delivery substantially increased whole-body lean mass and decreased fat mass, corresponding to higher myofiber cross-sectional area and smaller adipocyte size, respectively. Secretome-treated mice also had greater whole-bod...

Naked Mole Rats are Resistant to Ischemia, Such as Occurs Following a Heart Attack
On the one hand, naked mole-rats are most likely long-lived because they live underground, and thus suffer much lower rates of predation than other similarly sized mammals. Lower rates of extrinsic mortality appear to be a necessary prerequisite for the evolution of a longer species life span. On the other hand, living in a low-oxygen environment appears to have spurred the evolution of broad range of adaptations to that environment that incidentally happen to extend species longevity. Today's open access paper covers one aspect of those adaptations, a resistance to ischemia that reduces the harms resulting from the loss o...

A Survey of MicroRNAs Shown to be Relevant to Muscle Aging
RNA molecules are produced in the cell nucleus by transcription machinery that reads gene sequences from the genome. MicroRNAs are among the varieties of RNA molecule that are not translated by a ribosome to produce proteins. Instead they directly participate in cell functions, often by altering the expression of other genes. Many microRNAs appear to be important players in the regulation of specific cell behaviors and tissue functions, such as regeneration and maintenance of tissues.
In today's open access paper, the authors provide an overview of some of the microRNAs that have been identified as important or pote...

Raised Inflammatory Markers Somewhat Correlate with Incidence of Age-Related Disease
Onset, progression, and resolution of inflammation are all driven by the interaction of many different complex signaling processes. The immune system as a whole is highly complex, an array of many different interacting populations of specialized cells. Nonetheless, there are a few individual circulating signal proteins that, to some degree at least, tend to reflect overall inflammatory status. Not reliably, but enough to produce correlations in patient populations of any reasonable size.
Today's open access paper is a survey of the literature on inflammatory cytokines IL-6, TNF, and IL-1β, pulling reported measures...

A View of Type 2 Diabetes as Accelerated Aging
The mortality characteristics resulting from type 2 diabetes look very much like an accelerated form of normal aging, as noted in today's open access paper reporting on a large epidemiological study. This mortality characteristic is so much like aging that at times in the past researchers have used animal models of type 2 diabetes as stand-ins for aging, in order to conduct studies more rapidly. Type 2 diabetes is a metabolic disease, a condition that usually arises from excess fat tissue, and is characterized by chronic inflammation, excessive blood sugar, high levels of circulating advanced glycation end-products, and ot...

Interview with Stefany Shaheen: Revolutionizing diabetes care through cell therapies
I had the extraordinary opportunity to chat with Stefany Shaheen, the Chief Strategy Officer of Advanced Regenerative Manufacturing Institute (ARMI) and BioFab USA, about the transformative potential of cell therapies for individuals living with diabetes. Stefany shared her remarkable journey, insights on cell therapies’ current status, approval challenges, and how the diabetes community can contribute to advancing research in this field.
A few months before this discussion with Stefany, I had the opportunity to hear Dean Kamen speak at the recent ...

This study supports the proposed model that aging-related loss of colonic crypt epithelial cell AMP gene expression can promote increased relative abundances of Gn inflammaging-associated bacteria and gene expression markers of colonic inflammaging. These data may support new targets for aging-related therapies based on intestinal genes and microbiomes.

Problematic B Cells Accumulate in Visceral Fat and Indirectly Provoke Inflammation
The authors of today's open access paper present an interesting and novel way in which visceral fat tissue provokes chronic inflammation. It has been noted that dysfunctional B cells accumulate with age. Here, dysfunctional B cells of a specific subtype are shown to accumulate in aged visceral fat tissue, acting to provoke other immune cells in visceral fat tissue, such as macrophages, into a more pro-inflammatory state. The researchers demonstrate that removing the B cell population helps to reduce the age-related inflammation generated by visceral fat by removing the contribution to inflammatory macrophage behavior.

The Long and Tortured History of Alpha-Synuclein and Parkinson ’s Disease
This study tracks the decades-long journey to harness alpha-synuclein as a treatment for Parkinson’s disease. Steven Zecola an activist who tracks Parkinson’s research and was on THCB last month discussing it, offers three key changes needed to overcome the underlying challenges.
A Quick Start for Alpha-Synuclein R&D
In the mid-1990’s, Parkinson’s patient advocacy groups had become impatient by the absence of any major therapeutic advances in the 25 years since L-dopa had been approved for Parkinson’s disease (PD).
The Director of National Institute of Neurological Disorders and Stroke (NINDS) se...

A Skeptical View of the Role of Nuclear DNA Damage in Aging
It is evident and settled that stochastic nuclear DNA damage contributes to cancer. The more of it that you have, the worse your risk. What is still very much debated is whether nuclear DNA damage contributes meaningfully to degenerative aging, and how it does so. Most mutational damage to DNA occurs in regions that are inactive, in cells that have comparatively few divisions remaining before reaching the Hayflick limit. Even if damage alters the function of such a cell, in some non-cancerous way, it is unclear as to how this could amount to a meaningful contribution to loss of tissue function.
The one school of tho...

Interesting Epidemiological Results for Time Restricted Feeding
In this study, researchers investigated the potential long-term health impact of following an 8-hour time-restricted eating plan. They reviewed information about dietary patterns for participants in the annual 2003-2018 National Health and Nutrition Examination Surveys (NHANES) in comparison to data about people who died in the U.S., from 2003 through December 2019, from the Centers for Disease Control and Prevention's National Death Index database.
The analysis found: (a) people who followed a pattern of eating all of their food across less than 8 hours per day had a 91% higher risk of death due to cardiovascular d...
