BotswanaHuman Gene Found in Virus
Scientists discover a human gene that can jump through DNA and is found in a poxvirus, a gene that plays a role in brain cells and has retained its mobility. The gene, called BC200, was found to have jumped into a human virus from the pox family at least twice during modern human history.

Researchers at Cornell University have identified a human gene that can move around the genome and is also found in a poxvirus that infects humans. The gene, called BC200, is predominantly expressed in neurons and is thought to participate in the regulation of protein synthesis.
BC200 originates from a transposon, a mobile DNA element that can change its position in the genome. About half of the human genome consists of DNA of transposon origin, but most such elements are no longer active.
According to Cedric Feschotte, a senior author of the study, genes that arose from transposons and adapted to cellular functions usually lose their ability to move. However, BC200 combines a cellular function with mobility, making it a unique discovery.
The precise physiological role of BC200 has not yet been established, but available data suggest that it may affect the translation of messenger RNAs into proteins in nerve cells. BC200 is also present in small amounts in germ cells, which means it may have the potential to create new insertions in the genome that could be passed on to subsequent generations.
Scientists suggest that BC200 may have entered the molluscum contagiosum virus during infection of skin cells. The research team plans to determine whether BC200 moves actively in cancer cells and whether such movements can cause mutations.
BC200 is abnormally expressed in some tumors and has also been detected in elevated amounts in the brains of people with Alzheimer's disease. The discovery of BC200 in a poxvirus has significant implications for our understanding of the evolution of the human genome and the role of transposons in disease.
The study was published in the journal Science on September 24, and the researchers are continuing to investigate the properties and functions of BC200.
Key facts
- BC200 is a human gene that can move around the genome and is found in a poxvirus.
- The gene is predominantly expressed in neurons and is thought to participate in the regulation of protein synthesis.
- BC200 originates from a transposon, a mobile DNA element that can change its position in the genome.
- The gene is present in small amounts in germ cells, which means it may have the potential to create new insertions in the genome.
Three perspectives
Neutral
The discovery of BC200 in a poxvirus has significant implications for our understanding of the evolution of the human genome. Further research is needed to determine the exact role of BC200 in disease and its potential to create new insertions in the genome. The study's findings highlight the complex and dynamic nature of the human genome.
Positive
The discovery of BC200 is a significant breakthrough in our understanding of the human genome and its evolution. The gene's unique properties make it an important area of study, with potential implications for the development of new treatments for diseases such as cancer and Alzheimer's. The research team's findings demonstrate the importance of continued investment in scientific research.
Negative
The discovery of BC200 in a poxvirus raises concerns about the potential for the gene to contribute to disease. The gene's ability to move around the genome and create new insertions could have significant implications for human health, particularly if it is found to be active in cancer cells. Further research is needed to fully understand the risks and benefits associated with BC200.
