Meditation, often associated with stress reduction, could also influence biological mechanisms related to cancer. A team of researchers is exploring how this practice affects cellular communication and DNA repair.
Scientists have studied the effects of meditation on cancer survivors, focusing on extracellular vesicles, small particles that carry information between cells. Their goal: to understand whether this practice can alter biomarkers linked to inflammation and cellular repair, two key processes in disease prevention.
Extracellular vesicles, messengers of health
Extracellular vesicles (EVs) play a crucial role in cell-to-cell communication. Researchers have identified seven specific microRNAs in the EVs of individuals who practice meditation. These microRNAs could influence gene expression, thereby reducing inflammation and promoting cellular repair.
This discovery suggests that meditation could act at the molecular level, altering how cells interact. These findings open new perspectives for understanding how mental well-being can influence physical health.
An innovative technology to detect biomarkers
The team has also developed a portable device capable of quickly analyzing EVs in blood. Using synthetic antibodies, this device allows for precise and cost-effective detection of microRNAs. This technology could improve early diagnosis of diseases like cancer or Alzheimer's.
By enabling rapid analysis of biomarkers, this device could help anticipate diseases before symptoms appear. A major advancement for preventive medicine, which could significantly reduce healthcare costs.
Towards personalized preventive medicine
Researchers envision a future where early detection of biomarkers would allow for swift and targeted intervention. Meditation, combined with this technology, could become a key tool for maintaining optimal health.
This approach could transform how we view health, shifting from reactive medicine to proactive medicine. The implications could be immense, both for individuals and healthcare systems.
To go further: What is a microRNA?
MicroRNAs are small RNA molecules that regulate gene expression. They act by binding to messenger RNAs, thereby preventing the production of certain proteins. This mechanism influences numerous biological processes, such as cell growth or immune response.
Their role in diseases is increasingly studied. For example, some microRNAs are associated with cancer progression or neurodegenerative diseases. Their detection in blood or other biological fluids makes them promising biomarkers for early diagnosis.
MicroRNAs are transported by extracellular vesicles, which protect them and deliver them to other cells. This intercellular communication is essential for maintaining biological balance and responding to environmental stress.
Understanding how practices like meditation influence these molecules opens new perspectives in medicine. It could enable the development of non-invasive approaches to prevent or treat complex diseases.
