New fluorescent sensor detects cells aging from cancer and lung drugs
Researchers built a glowing probe that lights up only in certain aged cells. It may help scientists track these cells in living animals, but this is early lab work.
Mixing a senescence-clearing drug with trametinib slowed glioma regrowth in mice
Researchers found a drug combination that cleared aging-like tumour cells in mice and slowed regrowth. This does not show the combination would work the same way in children.
A vaccine-style treatment in mice eased diabetes signs and aged cell markers
Mice given a treatment aimed at a virus-like gene showed less weight gain and better blood sugar control. This study was in mice and cells, so it does not show the same would happen in people.
Aging cells that support stem cells may disrupt them through chemical signals
This is a review that pulls together older and newer studies. It proposes a model, but it does not show that the model is true.
Cx43 protein may boost breast cancer drug response in lab tests
Researchers studied a protein called Cx43 that helps cells talk to each other. They found it may help a breast cancer drug slow tumor growth. This early work is not yet checked by other scientists, so it does not show this would help people.
A new vaccine clears aging cells in mice and may extend lifespan
Researchers made a vaccine aimed at old, worn-out cells called senescent cells. In mice, it cleared some of these cells and helped metabolism. This is early work, so it does not show the vaccine would help people.
Computer study ranks possible drugs for kidney damage from diabetes
Researchers used open data on kidney tissue and drug patterns to rank drugs that might target aging cells. This is a computer study, so it suggests ideas but does not prove any drug works.
How aging-like cell stress may affect the eye's surface
This review summarizes earlier studies on senescence, a state where cells stop dividing and release inflammatory signals. It suggests this state can help or harm the eye's surface, depending on the situation.
Natural Killer Cell TGF-β Signaling Regulates Postnatal Lung Development.
BACKGROUND: Bronchopulmonary dysplasia (BPD) is a disease of neonatal lung development that is linked to impaired pulmonary vascularization, dysregulated TGF-β (transforming growth factor-β) signaling, and the…
How cancer treatment can leave behind aging cells that affect the tumor and immune system
This review looks at how cancer treatments can leave cells in a state of stress called senescence. It explains how these cells may help or hurt the immune system.
Aging cells may play a role in knee osteoarthritis, but the evidence is still early
This review looks at how aging cells may affect joint damage in osteoarthritis. It does not show that these cells cause the disease or that treatments aimed at them work in people.
Senolytic drug reduced skin scarring after radiation in mice
Researchers studied how radiation causes skin to stiffen and scar. They found a loop between aging cells and immune cells that seems to drive it. The drug ABT-263 reduced scarring in these mice, but this does not show it works in people.
Inducible chronic NAD deficiency in mice reveals multi-systemic phenotypical, metabolic, and transcriptional changes.
Nicotinamide adenine dinucleotide (NAD) is a metabolic cofactor regulating energy metabolism, epigenetics, DNA repair, and signaling.
Aging cells may link kidney disease and heart scarring, a review finds
This review suggests old, stuck cells may help connect kidney disease and heart stiffening. It does not prove that cause, and most cause-and-effect evidence comes from cells and animals.
Research on aging cells and heart failure has grown fast since 2020
This study counted and grouped 479 published papers on aging cells in heart failure. It shows where the research is going, but it does not show whether any treatment works.
Cell study finds death receptors shape which aging cells survive chemotherapy
Scientists found that certain death signals help control which damaged cells become senescent. The work does not show whether this would help people or patients.
How aging of blood vessel cells may keep pulmonary hypertension from reversing
This review gathers earlier data on how aged, worn-out cells in lung blood vessels may slow recovery in pulmonary hypertension. It does not show that treating these cells helps patients.
Harnessing autophagy and its transcriptional regulation in tumorigenesis and neurodegeneration: Potential and existing therapeutic strategies.
Autophagy is a fundamental cellular process that maintains homeostasis by degrading and recycling cellular components.
How aging muscle cells in blood vessels may drive heart and vessel disease
This review summarizes what scientists know about aging cells in blood vessel walls and possible drug targets. It describes ideas for future treatments, but it does not show that any treatment works in people.
Why artery aging may drive heart disease beyond cholesterol
This review pulls together recent and older studies on how aging blood vessels may fuel heart disease. It does not test a treatment, and it points to ideas still being studied.
Old, stuck cells may sometimes help cancer resist treatment
This review looks at how cells that stop dividing after cancer treatment might sometimes help tumors survive. The authors say these cells play a role only in some cases, not in every case.
Cell aging after cancer treatment may help or hurt tumour growth
This paper is a review of earlier research on aged cells and cancer. It says these cells may either slow or speed up tumour growth.
How osteoarthritis damages joints at the molecular level, and new treatment ideas
This review summarizes how cartilage breaks down over time in osteoarthritis, through many linked cell and chemical changes. It describes new treatment ideas that are being tested, but says some clinical trials gave mixed results.
How cancer treatment may age the heart and blood vessels in breast cancer patients
This review looks at how cancer treatments can leave some cells stuck in an aging state that may harm the heart. It does not prove this process causes heart damage, since other factors can also play a part.
A tea plant root extract killed aging skin cells in a lab dish
Researchers tested a tea root extract on human skin cells that had been made old in a dish. The extract killed more of the old cells than normal ones, and it also cut some inflammation signals. This does not show the extract works in people, because the tests were done in cells and skin samples.
Aging immune cells may drive Alzheimer's and Parkinson's, a review says
This review pulls together earlier studies on aging immune cells and brain disease. It suggests these cells may be a target for future treatments, but it does not prove this.
How aging of the immune system may affect rheumatoid arthritis
This review explains three aging-related ideas and how they may link to rheumatoid arthritis. It says causal proof in people is still limited, and much evidence comes from animal and non-arthritis studies.
How aging cell changes may relate to a type of heart failure
This review looked at studies linking aging cells and their chemical signals to a heart problem called HFpEF. The authors say most of the evidence so far comes from animal or lab work, or only shows links.
How aging immune systems may affect cancer immunotherapy in older adults
This is a review that pulls together earlier research on aging immune cells and cancer treatment. It says chronological age alone does not reliably predict how people respond to immunotherapy.
A drug pair tested in people with fatty liver disease and scarring
In this small trial, more people on dasatinib plus quercetin had liver scarring improve than those on placebo. The trial was small, and it does not show the drugs are safe or work for everyone.
