LiON: A fluorescent molecule tracks iron and oxygen levels in individual cells
A new fluorescent reporter capable of visualizing biologically active iron and oxygen inside living cells at single-cell resolution has been developed, as reported by researchers from Science Tokyo.
A new fluorescent reporter capable of visualizing biologically active iron and oxygen inside living cells at single-cell resolution has been developed, as reported by researchers from Science Tokyo. Using this new tool, they revealed striking differences in the distribution of iron and oxygen across organs and even between neighboring cells of the same type.
The short version
- This innovation could serve as a platform for studying cancer, liver diseases, neurodegeneration and aging.
- Iron and oxygen are two of the most essential ingredients for life.
- Nearly every cell in the body depends on them to produce energy, regulate metabolism and replicate DNA.
- Iron and oxygen are also deeply tied to diseases; disruptions in how cells handle these elements have been linked to cancer, liver problems, neurodegenerative disorders and aging-related conditions.
What the source reports
A solid understanding of how individual cells manage iron and oxygen could therefore open new doors in medicine and biotechnology. However, most existing methods for detecting iron require fixed tissue samples, meaning researchers can only look at snapshots of dead tissue rather than intact living cells. Modern imaging technologies such as magnetic resonance imaging do offer a broader view in real time, but they cannot zoom in to the scale of single cells.
Why it matters
Perhaps most critically, nearly all current tools measure total iron without distinguishing between the biologically active (labile ferrous iron) and inactive stored forms.
