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.
A review of how damaged nerves in the body repair their protective coating
This review gathers what is known about how nerve cells rebuild their coating after injury. It does not test a new treatment, and it suggests future treatments may need to be combined.
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.
