Considering the Mechanisms of Vascular Calcification
Harmful calcification of structures in the cardiovascular system proceeds alongside the development of the fatty lesions of atherosclerosis. Both disease processes are accelerated by chronic inflammation, but derive from very different, distinct underlying mechanisms. There is presently little that can be done to reverse calcification effectively; EDTA chelation therapy is the best option on the table at present, but isn't well regarded in the medical community. Other treatments are more focused on slowing the progression of calcification, and can achieve that goal to some degree.
The primary cause of worldwide mo...

Increased Dietary Leucine Activates mTOR Signaling in Macrophages, Accelerating Atherosclerosis
https://www.fightaging.org/archives/2024/02/increased-dietary-leucine-activates-mtor-signaling-in-macrophages-accelerating-atherosclerosis/
Leucine is an essential amino acid, only obtained from the diet rather than synthesized by our cells. Leucine supplementation has been proposed as a way to slow the loss of muscle mass with age, as leucine processing becomes dysregulated with aging in a way...

Amie Fornah Sankoh Achieves a Scientific Dream
Credit: LinkedIn.
“I wanted to give up so many times. Although I tried to remain positive, I never thought I’d be able to finish my Ph.D. But I made it, and I’m extremely proud of myself,” says Amie Fornah Sankoh, Ph.D., a research scientist with Dow Chemical Company who received NIGMS support as a graduate student.
Human and Plant Communication
Dr. Sankoh has loved science and mathematics since she was just a child growing up in Sierra Leone. When she was 3 years old, Dr. Sankoh became deaf from a childhood disease. Math, unlike other subjects, is very visual, which played a part in her interest in it. “...

Telomere Length as a Target for Therapy
Average telomere length in a tissue is some reflection of (a) stem cell activity and (b) pace of cell division. Telomeres, repeated DNA sequences at the ends of chromosomes, lose some of their length with each cell division, and cells self-destruct or become senescent when telomeres become too short. This limits the ability of somatic cells to replicate, reducing the odds that a given cell will mutate to become cancerous by imposing a limit on cell activity and cell life span, enforcing turnover of cells in tissues. Stem cells, in comparison, are a small, well protected, privileged set of cell populations that use telomera...

Reviewing the Development of Senotherapeutics to Treat Aging
https://www.fightaging.org/archives/2024/02/reviewing-the-development-of-senotherapeutics-to-treat-aging/
Senescent cells accumulate with age and contribute meaningfully to chronic inflammation and degenerative aging. Destroying these cells produces rapid and sizable reversal of age-related diseases in mice, demonstrating that the presence of senescence cells ...

This study aimed to explore the metabolic mechanisms and potential biomarkers associated with declining HGS among older adults. We recruited 15 age- and environment-matched inpatients (age, 77-90 years) with low or normal HGS. Liquid chromatography-mass spectrometry (LC-MS) and 16S ribosomal DNA (rDNA) gene sequencing were performed to analyze the metabolome of serum and stool samples and the gut microbiome composition of stool samples. Spearman's correlation analysis was used to identify the potential serum and fecal metabolites associated with HGS.
We assessed the levels of serum and fecal metabolites belonging to...

The 2024 Word of the Year: Missense
By MIKE MAGEE
Not surprisingly, my nominee for “word of the year” involves AI, and specifically “the language of human biology.”
As Eliezer Yudkowski, the founder of the Machine Intelligence Research Institute and coiner of the term “friendly AI” stated in Forbes:
“Anything that could give rise to smarter-than-human intelligence—in the form of Artificial Intelligence, brain-computer interfaces, or neuroscience-based human intelligence enhancement – wins hands down beyond contest as doing the most to change the world. Nothing else is even in the same league.”
Perhaps the ...

Advocating for Epigenetic Reprogramming as a Potential Rejuvenation Therapy
Partial epigenetic reprogramming emerges from the intersection of understanding how cells behave in cancerous tissue and during embryonic development. In the developing embryo there is a point at which adult germline cells convert themselves into embryonic stem cells, discarding forms of damage and dysfunction characteristic of adult cells and restoring a youthful pattern of the epigenetic markers attached to the genome that control its shape in the cell nucleus and thus gene expression. Some of the genes involved are known to also operate in cancers, in which replication and reprogramming runs wild, but which use many of ...

More Thought Needed on Causes versus Consequences in the Hallmarks of Aging
The hallmarks of aging are exactly that, hallmarks. They are not intended to be a list of causative mechanisms, though it appears that some people take it that way, particularly if it is supportive to their research and development program choices. Some of the hallmarks of aging overlap with the Strategies for Engineered Negligible Senescence (SENS) list of proposed causative mechanisms of aging, and the hallmarks paper itself clearly owes much to earlier SENS publications, as well as parallel proposals such as the Seven Pillars of Aging. It is important to target causes rather than consequences when it comes to aspects of...

Commentary on Gaps in the Knowledge of Aging
There are any number of sizable gaps in the understanding of how aging progresses at the detail level, which processes are more or less important, the direct of causation for many different interactions, and so forth. Aging is very complex because a living organism is very complex. Even simply causes produce complex outcomes when operating in a complex system. The same sizable gaps in understanding exist when we ask how and why aging evolved to be near universal across the tree of life, given that physical immortality appears possible for lower animals, and for much the same reasons. The evolutionary landscape is a complic...

HDL dysfunction & It ’ s clinical Implication
High-density lipoproteins (HDLs) represent a class of lipids, very heterogeneous in structure, composition, and biological functions .The density is between 1.063 to 1.210. It has at least 5 sub-types. Normal HDL level in blood should be above 35mg (50-60mg Ideal). When it goes beyond 60 there is not much benefit to accrue and also some surprise findings are there.(Article will be linked)
We know ,HDL carries free cholesterol from peripheral cells, including macrophages and endothelial cells. After reaching the liver, HDL receptors in the hepatocellular surface, metabolize it into bile acid or neutral lipids, which are ...
