Studies found that plant-derived miRNA can enter giant pandas' bloodstream and regulate gene expression, aiding adaptation to a bamboo-based diet. These tiny molecules may also influence taste and smell, enabling pandas to pick out nutritious bamboo.
Researchers found a significant increase in extracellular vesicles released by aged keratinocytes, which were also enriched with specific microRNAs. These EVs impaired young keratinocyte proliferation and organogenesis, mimicking aged skin defects.
Researchers at Northwestern University have discovered a way to soften stiff hair follicle stem cells, enabling them to grow hair again. By boosting the production of microRNA-205, they promote hair growth in both young and old mice, offering potential for human hair regrowth.
Researchers discovered that non-vascular bryophytes like Marchantia polymorpha adapt their architecture in response to shade, using phytochromes to regulate branching. The study found a liverwort-specific microRNA and SPL gene controlling meristem function, differing from vascular plants.
Researchers have identified microRNA-7 as a non-classic genetic risk factor for hereditary obesity. The molecule affects energy balance and appetite regulation in humans and mice, highlighting the need to examine non-genetic factors in gene-based studies. This discovery may lead to new therapeutic approaches for treating obesity.
