In conclusion, FMD cycles have high potential to be effective in increasing the toxicity of a range of therapies against ALL and other blood cancers and should be tested in randomized clinical trials, especially in combination with immunotherapy and low toxicity cancer therapies.
In summary, we present a new strategy for improving leukemia treatment by combining FMD with chemotherapy to promote the killing of ALL cells in part by an immune-dependent mechanism. Fasting/FMD has been shown to reduce chemotherapy-associated toxicity in pre-clinical and clinical studies and thus represents a safe and potentially effectiv...

Effects of LDLR Variants on Longevity via Lowered Cardiovascular Disease
This study suggests that LDLR is a promising genetic target for human longevity. Lipid-related gene targets, such as PCSK9, CETP, and APOC3, might potentially regulate human lifespan, thus offering promising prospects for developing newer nonstatin therapies.

A Direct Link Between Genomic Instability and Inflammation in Senescent Cells
Aging is characterized by constant sterile inflammation, a state that is disruptive to tissue structure and function. A number of forms of molecular damage have been shown via various mechanisms to provoke this inflammation. Mitochondrial dysfunction, for example causes mitochondrial DNA to mislocalize to the cytoplasm, where it triggers an innate immune response that evolved to recognize the presence of bacterial DNA. Mitochondria are the evolved descendants of ancient symbiotic bacteria, and their remnant DNA is close enough to bacterial genomes for this to occur.
In today's open access paper, researchers discuss ...

How Can the Immune System Go Awry?
This post is part of a miniseries on the immune system. Be sure to check out the other posts in this series that you may have missed.
The immune system is designed to closely monitor the body for signs of intruders that may cause infection. But what happens if it malfunctions? Overactive and underactive immune systems can both have negative effects on your health.
Autoimmune Disorders
To effectively monitor the body for pathogens, the adaptive immune system has to learn what a pathogen “looks like” on a molecular level. During their development, white blood cells go through training to learn how to differe...

A Look Back at 2023: Progress Towards the Treatment of Aging as a Medical Condition
The market has been in the doldrums and it has been a tough year for fundraising, both for non-profits and biotech startups. The conferences have exhibited more of an academic focus as companies tightened belts and postponed investment rounds, while investors stayed home. Not that this halts the flow of hype for some projects, and nor has it slowed media commentary on the longevity industry as it presently stands. A few of the articles in that commmentary are even interesting to read! The field has grown and is more mature now than has ever been the case. Biotech of all forms is a challenging field with a high failure rate...

CD38 in Ovarian Aging
The ovaries, like the thymus, are interesting for their comparatively early exhibition of age-related degeneration. Is there anything useful that can be learned about aging more generally by looking at the portions of the body that experience aging more rapidly? That remains to be seen. Here, researchers investigate NAD+ metabolism in the ovaries versus other tissues, noting that CD38, an enzyme that removes NAD+, is more active earlier in life. Approaches to maintain NAD+ levels slow ovarian aging, including knocking out CD38.
Delayed childbearing is prevalent worldwide, and ovarian senescence occurs earlier than...

Reviewing What is Known of the Mechanisms of Taurine Supplementation Relevant to Aging and Metabolism
Taurine is a semi-essential amino acid. Dietary taurine supplementation has been shown to modestly slow aging in mice, though as for all such interventions there is always the question of whether it will prove to be less useful in humans, and also whether these results in mice will be disproved by the much more rigorous Interventions Testing Program (ITP), once that group gets around to assessing taurine supplementation. Few of the numerous interventions thought to modestly slow aging in mice on the basis of earlier research actually held up once subjected to the ITP degree of experimental rigor.
Speculatively, taur...

This study generates a comprehensive single-cell transcriptomic atlas of human atherosclerosis including 118,578 high-quality cells from atherosclerotic coronary and carotid arteries. By performing systematic benchmarking of integration methods, we mitigated data overcorrection while separating major cell lineages. Notably, we define cell subtypes that have not been previously identified from individual human atherosclerosis scRNA-seq studies.
Besides characterizing granular cell-type diversity and communication, we leverage this atlas to provide insights into smooth muscle cell (SMC) modulation. We integrate genome...

Mineralocorticoid Receptors: MCQ
Mineralocorticoid Receptors are found in all of the following, Except? [1]
A. Liver
B. Colon
C. Hippocampus
D. Kidney
Correct answer : A. Liver
Mineralocorticoid receptors are found in sodium transporting epithelia like that in kidney and colon as well as in nonepithelial tissues like heart and brain [2]. They also have high affinity for glucocorticoids [3].
Aldosterone promotes myocardial fibroblast proliferation and has a role in myocardial fibrosis. This accounts for the beneficial antifibrotic effect of mineralocorticoid receptor antagonists when used in the management of heart failure [4].

The hidden costs of “ free ” medical interpretation
He is a typical patient of our academic primary care internal medicine practice: elderly, frail, and with several complex conditions, including a history of a liver transplant requiring chronic immunosuppression, recurrent venous thrombosis requiring treatment with blood thinners, and type 2 diabetes. But in one very important way, he is different: our doctors don’t speak

Nectandrin B Extends Life in Flies
In this study, we present evidence that Nectandrin B (NecB), a bioactive lignan compound isolated from nutmeg, significantly extended the lifespan of the fruit fly Drosophila melanogaster by as much as 42.6% compared to the control group. NecB also improved age-related symptoms including locomotive deterioration, body weight gain, eye degeneration, and neurodegeneration in aging D. melanogaster. This result represents the most substantial improvement in lifespan observed in animal experiments to date, suggesting that NecB may hold promise as a potential therapeutic agent for promoting longevity and addressing age-related d...

Profiling the Development of Gene Therapies at Rejuvenate Bio
Here find a high-level look at the work of Rejuvenate Bio, a gene therapy company aiming to manipulating aging metabolism into a better shape. They have chosen to focus on the strategy of altering tissues to generate signal molecules known to be influential in the progression of aging. This is perhaps the easiest way forward for any gene therapy platform. Gene therapies are clearly the future, but at present it is somewhere between hard, expensive, and impossible to specifically target a gene therapy to most organs or cell types or tissues. If one can use one of the few established approaches, such as delivery of a gene th...
