Imagine a simple topical treatment that could help aging skin heal faster, reducing recovery time from wounds and even improving skin quality. Scientists may have found exactly that. A recent study, published in Aging, reveals that a compound called ABT-263 can eliminate aging cells in the skin, boosting its ability to regenerate. 

Understanding How Aging Affects Skin Healing

Aging affects the skin’s structure and function, leading to a reduced ability to heal from wounds. Scientists have long suspected that senescent cells, also known as “zombie cells,” play a major role in this decline. These cells stop dividing but refuse to die, accumulating in tissues and releasing inflammatory molecules that impair the body’s natural repair processes.

Various studies have explored senolytics, a class of drugs designed to eliminate these aging cells and restore tissue function. While these drugs have shown promise in treating diseases like osteoporosis and fibrosis, their impact on skin regeneration and wound healing has been less studied. A new study titled “Topical ABT-263 treatment reduces aged skin senescence and improves subsequent wound healing” now suggests that a topical application of the senolytic ABT-263 could significantly improve wound healing in older individuals.

Longevity & Aging Series (S3, E3): Dr. Stephen Vatner

BUFFALO, NY — April 29, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 3, on March 20, 2025, titled “Inhibition of the metalloprotease ADAM19 as a novel senomorphic strategy to ameliorate gut permeability and senescence markers by modulating senescence-associated secretory phenotype (SASP).”

Researchers, led by first author Sudipta Bar and corresponding authors Amit Sharma and Pankaj Kapahi from the Buck Institute for Research on Aging, have found that the enzyme ADAM19 plays an important role in regulating aging in cells and inflammation in the gut. Their study shows that blocking ADAM19 reduced gut damage and inflammation in fruit flies, mice, and human cells. This discovery points to a new possible way to treat gut disorders related to aging by reducing the harmful signals from senescent (aging) cells.

As individuals age, DNA damage can lead to the accumulation of senescent cells, contributing to tissue damage. These are cells that stop dividing and release harmful inflammatory substances called the senescence-associated secretory phenotype (SASP). In this study, researchers used fruit flies to search for genes involved in radiation-related gut damage. They identified a gene called meltrin, which is similar to human ADAM19. When meltrin was turned off, the flies had less gut leakage, less inflammation, and fewer signs of cellular aging.

“Through an unbiased genome-wide association study (GWAS) utilizing 156 strains from the Drosophila Genetic Reference Panel (DGRP), we identified meltrin (the drosophila orthologue of mammalian ADAM19) as a potential modulator of the senescence-associated secretory phenotype (SASP).”

To test if these results applied beyond flies, the team inhibited ADAM19 in mice using a drug called batimastat. Mice treated with the drug after chemotherapy exposure had stronger gut barriers and lower levels of inflammatory markers. The findings extended to human cell cultures, where ADAM19 inhibition reduced signs of cellular aging, including the expression of SASP proteins and β-galactosidase, a classic aging marker. 

Importantly, this approach does not kill aging cells like many 'senolytic' therapies but instead reduces the harmful substances they release, making it a potential "senomorphic" strategy. The study also showed that ADAM19 helps release certain SASP proteins by cutting them at the cell surface, suggesting a direct role in regulating inflammatory signals.

Through proteomic analysis, the team identified 12 SASP proteins that were significantly reduced when ADAM19 was blocked. Many of these proteins are linked to inflammation, immune response, and tissue remodeling in diseases such as inflammatory bowel disease and Crohn’s disease. This connection underlines the relevance of the findings for treating chronic gut disorders in aging populations.

By targeting ADAM19, researchers may have found a new way to protect gut health and lower inflammation caused by aging cells. This study offers a promising path for creating treatments that maintain healthy tissues without having to destroy aging cells, which could benefit people with gut damage related to aging or medical treatments.

Inhibiting ADAM19 Reduces Gut Inflammation and Cell Aging Markers Across Species

BUFFALO, NY — May 1, 2025 — A new #research paper was #published in Aging (Aging-US) on April 2, 2025, as the #cover of Volume 17, Issue 4, titled “Decreased mitochondrial NAD+ in WRN deficient cells links to dysfunctional proliferation.”

In this study, the team led by first author Sofie Lautrup and corresponding author Evandro F. Fang, from the University of Oslo and Akershus University Hospital in Norway, discovered that cells from people with Werner syndrome (WS)—a rare genetic disorder that causes  premature aging—have low levels of a molecule called NAD+ in their mitochondria. This molecule is essential for energy production, cellular metabolism, and maintaining cell health. The researchers also found a potential way to improve cell function in WS patients, pointing to new directions for treating age-related decline and other premature aging disorders.

Werner syndrome leads to signs of aging much earlier than normal, including problems such as cataracts, hair loss, and atherosclerosis by age 20 to 30. The team found that when the WRN gene is missing or damaged, cells cannot maintain healthy NAD+ levels in their mitochondria. As a result, the cells age more quickly and stop growing properly. When the researchers boosted NAD+ levels using nicotinamide riboside (a vitamin B3 compound) the affected stem cells and skin cells from patients showed less aging and improved mitochondrial activity.

“Interestingly, only 24 h treatment with 1 mM nicotinamide riboside (NR), an NAD+ precursor, rescued multiple pathways in the WRN−/− cells, including increased expression of genes driving mitochondrial and metabolism-related pathways, as well as proliferation-related pathways.”

The study also found that the WRN gene helps regulate other important genes that control how NAD+ is made in the body. Without WRN, this system becomes unbalanced, which affects how cells function, grow, and respond to stress. Although adding more NAD+ helped some cells look healthier, it could not completely fix the growth problems in other types of lab-grown cells. This suggests that while NAD+ supplementation is beneficial, it cannot fully replace the essential functions of the WRN gene.

These findings offer new insights into the biological mechanisms of aging and reinforce the therapeutic potential of targeting NAD+ metabolism in age-related and genetic diseases. Future studies will aim to better understand how subcellular NAD+ regulation interacts with mutations like those seen in WS. Finally, this research supports ongoing efforts to develop NAD+-based treatments that could slow cellular aging and improve quality of life for patients with premature aging conditions.

Oncotarget Participation at SSP 2025 Annual Meeting

BUFFALO, NY — May 6, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 4, on April 2, 2025, titled “Fisetin ameliorates vascular smooth muscle cell calcification via DUSP1-dependent p38 MAPK inhibition.”

In this study, researchers at Johannes Kepler University Linz found that fisetin, a natural substance found in fruits and vegetables, helps protect blood vessels from hardening, which is a common problem in older adults and people with kidney disease. This discovery highlights fisetin’s potential to prevent vascular calcification and reduce cardiovascular damage caused by aging and chronic kidney disease.

The research, led by first author Mehdi Razazian and corresponding author Ioana Alesutan, focused on vascular calcification—a condition in which blood vessels stiffen due to calcium deposits. This process is common in aging and chronic kidney disease and increases the risk of heart attacks and strokes. Using human and mouse study models, the researchers tested fisetin’s ability to prevent this calcification in vascular smooth muscle cells (VSMC), which play a key role in maintaining vessel health. Fisetin, known for its anti-inflammatory and antioxidant properties, significantly reduced calcium buildup and calcification markers under stress conditions that mimic disease.

The team also discovered that fisetin suppresses activity in a signaling pathway called p38 MAPK, which is known to promote calcification. This effect depends on a protein called DUSP1. When DUSP1 was blocked, fisetin could no longer protect the cells, showing that this protein is essential for its anti-calcification activity. The researchers confirmed fisetin’s protective effects in isolated mouse arteries and in living mice treated with high doses of vitamin D, which typically increases arterial calcification.

“Mechanistically, fisetin requires the phosphatase DUSP1 to inhibit p38 MAPK in order to mediate its protective effect on VSMC calcification.”

Importantly, the researchers tested fisetin under conditions similar to human disease. When VSMCs were exposed to blood serum from kidney dialysis patients—a condition known to trigger vascular calcification—fisetin again reduced calcium buildup and protected the cells. These findings suggest fisetin could be useful in countering the harmful vascular effects seen in chronic kidney disease.

This study adds to growing evidence that fisetin may protect blood vessels from aging-related damage. While more research is needed before it can be used in clinical treatments, the study highlights fisetin as a promising candidate for slowing or preventing vascular calcification. The findings could have broad implications for aging populations and individuals with kidney disease, who are at greater risk for heart problems due to vascular stiffening.

Fisetin, a Natural Compound, Helps Prevent Artery Hardening from Aging and Kidney Disease

BUFFALO, NY — May 7, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 4, on April 4, 2025, titled “Influence of rapamycin on safety and healthspan metrics after one year: PEARL trial results.”

A research team led by first author Mauricio Moel and corresponding author Stefanie L. Morgan from AgelessRx conducted a clinical trial to determine whether low-dose, intermittent rapamycin could safely improve healthspan in older adults. The findings suggest rapamycin may offer measurable benefits for physical function and overall well-being, reinforcing its potential as a safe intervention to support healthy aging.

Aging remains the leading cause of chronic conditions such as heart disease, diabetes, and dementia. While medical advances have extended lifespan, many people still experience declining health and reduced mobility in later years. This growing gap between lifespan and healthspan has driven interest in therapies that target aging itself. Rapamycin, an FDA-approved drug originally used in transplant medicine, has drawn attention for its ability to influence aging-related pathways in animal studies. Until recently, its safety and benefits in healthy human populations were largely unknown.

The PEARL trial is the longest study so far to explore rapamycin’s use for longevity in healthy aging adults. Researchers followed 114 participants aged 50 to 85 over 48 weeks in a randomized, double-blind, placebo-controlled design. Participants received either a placebo or 5 mg or 10 mg of compounded rapamycin once per week. The study’s primary goal was to measure changes in visceral fat, while secondary outcomes included lean muscle mass, blood markers, and quality-of-life assessments.

The trial found that low-dose rapamycin was safe and well-tolerated, with serious side effects reported at similar rates across all groups. The most frequent minor issue among rapamycin users was mild gastrointestinal discomfort. While no significant reductions in visceral fat were observed, women taking 10 mg of rapamycin showed significant gains in lean muscle and reported reduced pain. In addition, participants taking 5 mg weekly reported improvements in emotional well-being and general health, as measured by validated surveys.

“Our findings provide evidence that these rapamycin regimens are well tolerated with minimal adverse effects when administered for at least one year within normative aging individuals.”

Researchers noted some limitations, including the relatively small and health-conscious participant group, which may have limited the ability to detect larger effects. The compounded form of rapamycin used also had lower absorption than commercial versions, possibly reducing its impact.

Overall, the PEARL trial provides early clinical evidence that low-dose rapamycin may help support physical and emotional well-being in older adults. Further studies with larger and more diverse populations will be essential to confirm the study results and refine dosing strategies for broader application.

Low-Dose Rapamycin Improves Muscle Mass and Well-Being in Aging Adults

A recent #study from Assiut University Hospital in Egypt, published in #Oncotarget, presents a promising strategy for patients with metastatic #colorectalcancer (mCRC). The #research introduces a gentler yet effective maintenance therapy that may extend survival, enhance quality of life, and offer a more accessible treatment option for mCRC patients worldwide.

The Challenge of Treating Metastatic Colorectal Cancer

Colorectal cancer is one of the most common causes of cancer-related deaths worldwide. When it spreads to other parts of the body—a stage known as mCRC—it becomes much more difficult to treat. At this stage, clinicians often use strong drug combinations like FOLFOX or CAPOX, which mix chemotherapy drugs to stop cancer growth. FOLFOX combines three drugs given intravenously, while CAPOX includes two of the same drugs, with one taken as a pill.

While effective, these treatments can cause serious side effects. For example, one of the main drugs, oxaliplatin, can lead to nerve damage, making it painful or difficult to use the hands and feet. Fatigue, diarrhea, and other issues are also common. Over time, these side effects may force clinicians to stop or adjust the treatment, even if it is working.

That is where maintenance therapy comes in. After the cancer is controlled, clinicians often switch to a gentler treatment plan to keep it from returning. The challenge is finding a therapy that continues to work without causing too many side effects, especially in places where access to expensive or intensive treatments is limited.

Panitumumab & Low-Dose Capecitabine: Promising Maintenance Therapy for Metastatic Colorectal Cancer

BUFFALO, NY - May 9, 2025 – A new #research paper was #published in Oncotarget, Volume 16, on May 8, 2025, titled “METTL3 promotes oral squamous cell carcinoma by regulating miR-146a-5p/SMAD4 axis."

In this study, researchers Jayasree Peroth Jayaprakash, Pragati Karemore, and Piyush Khandelia from the Birla Institute of Technology and Science, India, discovered that a molecule called METTL3 contributes to the development and spread of oral squamous cell carcinoma (OSCC). The study shows that METTL3 increases the levels of a small RNA molecule called miR-146a-5p, which blocks SMAD4, a key tumor-suppressing gene. These findings help explain why oral cancers are difficult to treat and may offer a new target for more effective therapies.

Oral squamous cell carcinoma is a common and aggressive cancer affecting the mouth and throat. It has a high death rate, mainly due to late detection, treatment resistance, and the cancer’s ability to invade nearby tissues. In this study, the researchers focused on METTL3, an enzyme that adds chemical tags known as m6A marks to RNA, which change how genetic information is used by cells. They found that METTL3 is unusually active in OSCC cells, causing an increase in miR-146a-5p. This molecule, in turn, blocks the function of SMAD4, which helps control how cells grow and die in our bodies.

“METTL3, the primary m6A RNA methyltransferase, is significantly upregulated in OSCC cells leading to increased global m6A levels.”

When METTL3 was reduced or chemically blocked, miR-146a-5p levels dropped and SMAD4 levels increased. This shift slowed the growth of cancer cells, increased their death, and made them less likely to spread. When researchers reintroduced miR-146a-5p or lowered SMAD4 levels again, the cancer-promoting behavior returned. These results show that the METTL3–miR-146a-5p–SMAD4 pathway plays a key role in OSCC.

The findings open up new possibilities for treatment. Drugs that block METTL3 or miR-146a-5p or that restore SMAD4 could slow or stop tumor growth. One such drug, STM2457, which targets METTL3, has already shown promise in lab studies. As research progresses, targeting this molecular pathway may offer a new strategy in treating OSCC.

This discovery improves our understanding of how OSCC develops and avoids the body’s defenses. By interfering with this newly discovered pathway, future treatments may become more successful, improving survival rates and quality of life for people with this disease.
