A Review of Fasting and Calorie Restriction

Today, we want to discuss a review published in the journal Science, as it provides a whistle-stop tour of caloric restriction, intermittent fasting, and time-restricted feeding [1]. There is a

Drug that Slows Alzheimer’s Successful

Through a new approach dubbed AMBAR, the biotechnology company Grifols has attempted to reduce the amount of harmful, Alzheimer’s disease-causing amyloid beta in the brain by collecting it with a

Type of Human Monocytes Found to Undergo Senescence

Scientists from the A*STAR Singapore Immunology Network have discovered that immune cells called nonclassical monocytes undergo cellular senescence, contradicting what was previously thought of them [1]. Abstract Human primary monocytes

Forcing Cancer to Put up a Broken Shield

Led by Dr. Alicja Copik, scientists at the University of Central Florida College of Medicine have discovered that it might be possible to make cancer immunotherapy work for a larger

DNA Replication Can Happen Without ORC1

According to a study conducted by Hollings Cancer Center scientists at the Medical University of South Carolina, DNA replication in murine cells is possible even in the absence of origin

Human Stem Cell Trial Successful Against Age-Related Frailty

Today, we want to highlight results from human trials in which stem cell transplants have been shown to reduce age-related frailty. Age-related frailty and stem cell transplants Currently, there are no specific approved therapies to address age-related frailty, which can cause elderly people to suffer potentially

A Review of Fasting and Calorie Restriction

Today, we want to discuss a review published in the journal Science, as it provides a whistle-stop tour of caloric restriction, intermittent fasting, and time-restricted feeding [1]. There is a considerable amount of data supporting the effects of caloric restriction and similar dietary approaches on both

Too much mTOR is Linked to Diabetes and Aging

A new study takes a look at the relationship between metabolism, aging, and type 2 diabetes and in particular the mTORC1 protein complex, part of the mTOR pathway. The mTOR pathway The mechanistic target of rapamycin (mTOR) pathway is a major part of metabolism and is

Plasma NAD+ Levels Decline Significantly with Age

Today, we want to highlight a recent, small-scale study looking at NAD+ and how it declines with age in the plasma. The researchers looked at various NAD+ metabolites across age groups and found that the amounts of some of them, particularly NAD+ itself, are significantly smaller

Drug that Slows Alzheimer’s Successful

Through a new approach dubbed AMBAR, the biotechnology company Grifols has attempted to reduce the amount of harmful, Alzheimer’s disease-causing amyloid beta in the brain by collecting it with a blood protein called albumin and draining it out of the bloodstream. This approach differs from the

Protein Produced by Astrocytes Involved in Brain Plasticity

Researchers from the Salk Institute have discovered that a protein called Chrdl1, secreted by astrocytes, is responsible for driving synapse maturation and limiting brain plasticity later in life [1]. Abstract In the developing brain, immature synapses contain calcium-permeable AMPA glutamate receptors (AMPARs) that are subsequently replaced

Type of Human Monocytes Found to Undergo Senescence

Scientists from the A*STAR Singapore Immunology Network have discovered that immune cells called nonclassical monocytes undergo cellular senescence, contradicting what was previously thought of them [1]. Abstract Human primary monocytes comprise a heterogeneous population that can be classified into three subsets based on CD14 and CD16

Scarlet Protein Might Protect Against Parkinson’s Disease

Researchers at the Department of Biological Sciences at Lehigh University in Bethlehem, Pennsylvania, discovered that a protein known as Scarlet has protective effects against the fruit fly version of Parkinson’s disease [1]. Abstract Parkinson’s Disease (PD) is characterized by the loss of dopaminergic neurons, resulting in

Fisetin Found in Strawberries Clears Senescent Cells in Mice

Today, we want to bring your attention to a recent mouse study on fisetin, a commonly available supplement that has proven effective at destroying senescent cells. What are senescent cells? As we age, increasing amounts of our cells enter into a state known as senescence. Normally,

Forcing Cancer to Put up a Broken Shield

Led by Dr. Alicja Copik, scientists at the University of Central Florida College of Medicine have discovered that it might be possible to make cancer immunotherapy work for a larger portion of patients by employing PM21-activated natural killer (PM21-NK) cells [1]. Study abstract Anti-PD-1/anti-PD-L1 therapies have

Administering Gene Therapy Without Triggering Immune Response

Scientists at Stanford University School of Medicine managed to administer effective gene therapy in mice without triggering an autoimmune reaction. The research, led by Dr. Peggy Ho, Ph.D., was published in the Proceedings of the National Academy of Sciences [1]. Study abstract In gene therapy for

A Review of Cellular Senescence and Senolytics

Today, we want to point out a new publication that dives into the world of senolytics, which are drugs or therapies that seek and destroy harmful non-dividing cells that resist the programmed cell death known as apoptosis. These cells linger in the body, and, as we

NAD+ Repletion Shows Potential Against Aging

Science is advancing rapidly, and the field of aging research is no exception. Our understanding of aging has grown a great deal in the last decade, and we are now reaching the point at which the first therapies that target aging are starting to arrive. Unlike

DNA Replication Can Happen Without ORC1

According to a study conducted by Hollings Cancer Center scientists at the Medical University of South Carolina, DNA replication in murine cells is possible even in the absence of origin recognition complex 1 (ORC1), a protein encoded by the homonymous gene that was previously thought to

Telomerase Gene Therapy Does Not Increase Cancer Risk

Researchers have demonstrated that telomerase gene therapy does not increase the risk of cancer, even in strains of mice that are particularly susceptible to cancer [1]. A tale of telomeres Short telomeres trigger cellular senescence and are thought to be one of the primary hallmarks of
