Scientists have identified the gene SLC35F2 that allows the micronutrient queuosine to enter human cells, revealing its crucial role in gene regulation, brain health, and cancer prevention, which could lead to new therapies and a better understanding of diet and genetics.
New research led by Amy Palmer, a professor in the University of Colorado Boulder Department of Biochemistry, has revealed the vital role of zinc in cell growth. Using genetically encoded fluorescent sensors, the study found that cell proliferation halts when zinc levels are too low or too high. The researchers also discovered a "zinc pulse" phenomenon, where cells experience a transient increase in zinc right after division. This breakthrough sheds light on the importance of zinc in various essential functions, such as DNA creation, immune system support, and protein building. Understanding the cellular mechanisms of zinc could have implications for human nutrition and disease.
Taurine, a micronutrient found in meat, fish, and dairy products, has been proven to slow the ageing process and extend the lifespan of mice by up to 10%. Scientists are calling for a major clinical trial on taurine to progress their findings on humans. Taurine supports cell function and helps energy production by supporting the health of mitochondria in cells. While testing on humans is yet to commence, researchers advise people against proactively increasing their taurine intake until more is known.
