Piecing together the LanCL puzzle

Researchers from the Carl R. Woese Institute for Genomic Biology in collaboration with scientists at Oxford University have published a paper in
Cell reporting the function of LanCL proteins. These proteins are found in eukaryotic cells but their function was previously unknown. The study is the first step towards understanding the importance of these ubiquitous proteins.
Bacteria contain enzymes called LanC that are capable of producing small proteins called lanthipeptides, which are characterized by the addition of a thiol group to a modified serine or threonine amino acid. Similar proteins called LanC-like or LanCL have been found in different eukaryotic cells for decades, but their function was unknown. ....

Basic cell health systems wear down in Huntington's disease, analysis shows


Basic cell health systems wear down in Huntington’s disease, analysis shows
February 26, 2021MIT
A new computational approach for analyzing complex datasets shows that as disease progresses, neurons and astrocytes lose the ability to maintain homeostasis.
Using an innovative computational approach to analyze vast brain cell gene expression datasets, researchers at MIT and Sorbonne Université have found that Huntington’s disease may progress to advanced stages more because of a degradation of the cells’ health maintenance systems than because of increased damage from the disease pathology itself.
The analysis yielded a trove of specific gene networks governing molecular pathways that disease researchers may now be able to target to better sustain brain cell health amid the devastating neurodegenerative disorder, says co-senior author Myriam Heiman, associate professor in MIT’s Department of Brain and Cognitive Sciences and an investigator at The Picower In ....
