Injecting miR-302b into Mice Reverses Signs of Aging, Study Finds
In a groundbreaking study published in Cell Metabolism, researchers have discovered that injecting the molecule miR-302b into aging mice can reverse some of the most prominent signs of aging. This includes regrowth of fur, improved physical abilities, and enhanced cognitive function. The findings, reported by Nature on January 17, 2025, offer a promising glimpse into the potential of miR-302b as a key player in anti-aging therapies.
The study focused on cellular senescence, a hallmark of aging where cells lose thier ability to replicate. As cells age, they release cytokines, chemicals that trigger inflammation and are linked to diseases like cancer, cardiovascular conditions, diabetes, and cognitive decline. By targeting this process, miR-302b appears to mitigate the effects of aging at a cellular level.
miR-302b is a type of microRNA, a small molecule involved in gene regulation.Previous research has shown its role in immunity and cancer cell suppression, but this study highlights its potential in combating aging. The researchers observed that treated mice not only lived longer but also exhibited restored fur growth and increased body weight compared to untreated mice [[1]].
The implications of this research are profound. While the study was conducted on mice, the findings could pave the way for the growth of anti-aging drugs for humans. Though, the researchers caution that further studies are needed to determine the molecule’s efficacy and safety in humans.

Breakthrough in anti-Aging Research: miR-302b shows Promise in Extending Lifespan and Improving Health
In a groundbreaking study led by Dr. Guangju Ji of the Institute of Biophysics at the Chinese Academy of Sciences (CAS), researchers have discovered that a specific microRNA, miR-302b, could hold the key to reversing aging and extending lifespan. This discovery, made using lab-cultured human cells and live mice, has sparked excitement in the scientific community, though experts caution that more research is needed to ensure its safety and efficacy in humans.
The Role of MicroRNA in Aging
MicroRNAs are small pieces of RNA, typically consisting of 20 to 24 nucleic acids, that play a crucial role in regulating gene expression. Unlike DNA, wich acts as a blueprint for proteins, microRNAs function as supervisors, ensuring the quality and efficiency of cellular processes.In this study, researchers focused on miR-302b, a microRNA found in exosomes—tiny vesicles that transport RNA between cells.
Using human embryonic stem cell-derived exosomes, the team discovered that miR-302b could restore the proliferative ability of aged cells. This microRNA was found to influence two genes involved in cell division, effectively rejuvenating older cells.
Promising Results in mice
To test the effects of miR-302b in living organisms, researchers conducted experiments on mice aged 20 to 25 months, equivalent to 60 to 70 years in human terms. Some mice were injected with normal human exosomes, while others received exosomes enriched with miR-302b. A control group was given a saline solution.
The results were striking. Mice treated with miR-302b lived 4.5 months longer on average compared to the control group. These mice also exhibited meaningful improvements in physical and cognitive functions, including:
- Regrowth of thinning fur
- Maintenance of higher body weight
- Improved balance on a spinning bar
- Enhanced grip strength relative to body weight
Additionally, treated mice had lower levels of inflammatory proteins in their blood and performed better in maze escape tasks. Dr. Ji noted, “These results comprehensively demonstrate that treatment with miR-302b not only extends the lifespan of mice but also significantly improves physical and cognitive functions while reducing aging indicators.”
Cautious Optimism from Experts
While the findings are promising, experts like professor Irina Conboy of UC Berkeley emphasize the need for further research. “There are some positive signals, but unknown signals were also discovered,” she said. Professor Conboy highlighted the importance of confirming whether miR-302b has a genuine anti-aging effect and ensuring it does not cause side effects in humans.
She also pointed out a critical difference between mice and humans: “On average, mice live a few months longer than humans live for several years, and they can get cancer during that time.” This underscores the need for extensive studies to determine the long-term safety and efficacy of miR-302b in humans.
