Many Researchers and Companies Will Aim to Produce Small Molecule Reprogramming Therapies
The typical path for any program in biomedical research and development is to first demonstrate interesting results in animal studies using forms of genetic engineering or gene therapy, and then find small molecules that adjust the same mechanism. Small molecules are never as good as genetic manipulations, the size of the effect is always smaller, usually much smaller, and there are inevitably side-effects. Small molecule development is much easier to conduct, however, more familiar to investors and regulators and program managers, a well-trodden path. Thus while the future of medicine is gene therapy, in search of large e...

In conclusion, although the contribution of CRF to GrimAgeAccel and FitAgeAccel is relatively low compared to lifestyle-related factors such as smoking, the results suggest that the maintenance of CRF is associated with delayed biological ageing in older men.

Gene Therapy Targets Chronic Pain
Scientists at New York University have developed a gene therapy for chronic pain. The technology works by targeting the NaV1.7 sodium ion channel present on neurons, which is an important component of the pain response. The researchers encoded a vers...

The Longevity-Associated Variant of BPIFB4 Reduces Heart Disease Severity
Few human longevity-associated gene variants are replicated in multiple patient populations. One of those is a variant of BPIFB4, that appears to improve immune function and lower inflammation by adjusting the behavior of macrophage cells of the innate immune system. Delivering the variant to mice using a gene therapy has similar effects. It may well operate via other mechanisms as well, however. Few proteins in a living cell turn out to have only one purpose.
In today's open access paper, researchers report that the BPIFB4 variant reduces the severity of coronary artery disease in humans and mice. Delivering the va...

Does Amyloid-β Aggregation Cause Broad Disruption of Proteostasis?
https://www.fightaging.org/archives/2023/08/does-amyloid-%ce%b2-aggregation-cause-broad-disruption-of-proteostasis/
Researchers here speculate on the ability of insoluble amyloid-β aggregates to be broadly disruptive of the solubility of many other proteins, and thus disruptive to cell and tissue function. Is this important in aging? The evidence here shows the existence of the mechanism in a lower species, but that doesn't n...

Developing Therapies to Treat Aging is No Less Challenging than Other Areas of Biotech
The biotech industry experiences a high failure rate, if we wish to define failure as failing to achieve the original goals of the research program that gave rise to a company. The article noted here opens with many examples to give a sense of the prevalence of companies in the early aging-focused space that altered their course to give a return to their investors by other means, after it proved too challenging to achieve the original vision. This is par for the course: the development of novel medical biotechnology is both very difficult and highly regulated. The grail of producing new medicine that is accepted by the reg...

In conclusion, an SBP level below 130 mmHg was found to be associated with longevity among older women. The longer SBP was controlled at a level between 110 and 130 mmHg, the higher the survival probability to age 90. Preventing age-related rises in SBP and increasing the time with controlled BP levels constitute important measures for achieving longevity.

In this study, we tested the hypothesis that periodontal disease (PD) as a source of infection alters inflammatory activation and Aβ phagocytosis by the microglial cells.
Experimental PD was induced using ligatures in C57BL/6 mice for 1, 10, 20, and 30 days to assess the progression of PD. Animals without ligatures were used as controls. Ligature placement caused progressive periodontal disease and bone resorption that was already significant on day 1 post-ligation and continued to increase until day 30. The severity of periodontal disease increased the frequency of activated microglia in the brains on day 30 by 36...

Further Work on Small Molecules that Can Induce Cell Reprogramming
In this study, we developed and utilized novel screening methods including a quantitative nucleocytoplasmic compartmentalization assay (NCC) that can readily distinguish between young, old, and senescent cells. We identify a variety of novel chemical cocktails capable of rejuvenating cells and reversing transcriptomic age to a similar extent as OSK overexpression. Thus, it is possible to reverse aspects of aging without erasing cell identity using chemical rather than genetic means.

In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues.

Recombinant Klotho Treatment Improves Cognitive Function in Old Rhesus Macaques
Klotho is one of the few genuinely longevity-associated genes, in that greater than normal expression increases life span in mice, while lower than normal expression shortens life span in mice. In humans, greater levels of circulating soluble klotho correlate with greater longevity. Klotho is thought to operate in the kidneys, in some way that is protective against the mechanisms of age-related decline, but there is a great deal of evidence for greater circulating klotho to improve cognitive function. At the same time, it seems unclear as to whether klotho is actually doing anything in the brain; it may be that the benefit...

In this study, cultured adipose-derived stem cells (ASCs) were derived from subcutaneous white adipose tissue isolated from mice fed a normal diet. We performed senescence-associated-β-galactosidase (SA-β-gal) staining, real-time PCR, and Western blot to evaluate the levels related to cellular senescence markers.
The mRNA expression levels of senescence markers were significantly increased in the later passages of ASCs. We show that light activation reduced the expression of senescent genes, and SA-β-Gal in all cells at passages. Moreover, the light-activated ASCs-derived exosomes decrease the expression of senes...

Age-Related Dysfunction of Water Homeostasis
https://www.fightaging.org/archives/2023/06/age-related-dysfunction-of-water-homeostasis/
Dehydration can be an issue in older people. As in every complex system in the body, the mechanisms by which hydration is regulated become dysfunctional with advancing age. Researchers here look at the brain region responsible for regulating some of the response to dehydration, cataloging altered gene expression in search of the more important mechani...
