Study in Nature Reveals Genetic Determinants of Micronucleus Formation and Implications for Human Disease
A recent study published in Nature has uncovered crucial insights into genomic instability and its implications for various diseases. The research delved into the mechanisms underlying the sequestration of DNA in aberrant extranuclear structures known as micronuclei (MN), associated with genomic instability, aging, and diseases linked to DNA damage and mitotic chromosomal imbalances. The study identified 145 genes that play a significant role in either increasing or decreasing MN formation, many of which have orthologues associated with human diseases, highlighting the potential clinical relevance of the findings. The identification of Dscc1 as a gene whose loss significantly increases MN formation and the validation of the DSCC1-associated MN instability phenotype in human cells offer insights into potential therapeutic avenues for addressing genomic instability.

Scientists Develop World’s First 3D-Printed Brain Tissue with Potential to Revolutionize Neuroscience and Brain Disorder Treatments
Scientists in Wisconsin, USA, have achieved a groundbreaking feat in the field of neuroscience by developing the world’s first 3D-printed brain tissue that mimics the functionality of natural brain tissue. This development is a significant stride towards the advancement of treatments for neurological and neurodevelopmental disorders such as Alzheimer’s and Parkinson’s disease. The innovative approach employed by the scientists involved the use of a 3D printer that departed from the conventional method of stacking layers vertically. Instead, they utilized a horizontal layering technique and placed brain cells, specifically neurons derived from induced pluripotent stem cells, in a softer ‘bio-ink’ gel compared to previous attempts. According to Su-Chun Zhang, a professor of neuroscience and neurology at UW–Madison’s Waisman Center, the 3D-printed brain tissue provides a powerful model for understanding human brain cell communication. This breakthrough has the potential to revolutionize stem cell biology, neuroscience, and the understanding of various neurological and psychiatric disorders.
