Summary:
A team of scientists from Genome Institute of Singapore (GIS) of the Agency for Science, Technology and Research (A*STAR) have shown how proteins involved in controlling genes work together to carry out their functions in stem cells and demonstrated for the very first time, how they can change interaction partners to make other types of cells. The work highlighted the collaborative nature of modern biology in which techniques and knowledge from bioinformatics analysis, structural biology, biochemistry and stem cell molecular biology were used together to find the specific amino acid within the protein that facilitated the molecular switch between stem cells and other types of cells. This discovery, published in the journal Stem Cells, has implications for generating stem cells more efficiently for biomedical applications and could help facilitate the development of treatments for diseases such as diabetes, Parkinson's disease, and Huntington's disease.
