To delve deeper into our genetic makeup, scientists have created a comprehensive database of genes that are still shrouded in mystery. These genes exist, and although they code for proteins, their exact functions have remained elusive. This database, known as the Unknome database, aims to shed light on these enigmatic genes and encourage further research into their potential significance in biology.
Over the past 20 years, since the initial release of the human genome sequence, our knowledge has expanded tremendously. However, there are still thousands of genes that have not received the attention they deserve. Molecular biologist João Rocha and his colleagues from the MRC Laboratory of Molecular Biology in the UK highlight several reasons for this neglect.
One major factor is the skewed funding and peer review systems that prioritize research on genes that already have proven clinical importance or are more common in laboratory species. As a result, these lesser-known genes have been overlooked, leaving a significant gap in our understanding of human biology.
To address this issue, the researchers developed the Unknome database, which is publicly available and customizable. The database ranks protein-coding genes based on their level of knowledge, highlighting the genes with the least amount of information. It encompasses genes from humans and other species commonly studied in laboratory settings.
This database serves as a valuable resource for scientists seeking to explore the uncharted territory of gene functions. By identifying and selecting genes of unknown function, researchers can accelerate the closure of knowledge gaps within the field of biology.
To demonstrate the practicality of the Unknome database, the researchers conducted a study involving 260 highly unknown genes found in the laboratory fly, Drosophila. They systematically deleted these shared genes in developing flies and observed the outcomes.
The findings revealed that many of the flies did not survive, indicating that these genes play a crucial role in animal biology. Additionally, by selectively removing gene expression in specific tissues within the flies, the researchers were able to uncover some of the gene’s functions. They discovered associations with male fertility, development, and stress responses.
This experiment highlights the immense potential in investigating these uncharacterized genes. Their neglect has been unwarranted, and by delving further into their functions, we may discover groundbreaking insights into various biological processes.
The Unknome database serves as a catalyst for scientific progress by identifying areas of research that have been inadvertently neglected. By shining a spotlight on these neglected questions within the human genome, Rocha and his colleagues are urging researchers worldwide to contribute to the acceleration of scientific knowledge.
The Unknome database provides a powerful and efficient platform for identifying and selecting genes of unknown function for analysis. By bridging the gap in biological knowledge, this database paves the way for groundbreaking discoveries in genetics and biology. It is now up to researchers around the world to embrace the opportunities within the Unknome database and unravel the mysteries hidden within our genetic blueprint.
