A genetic variant in the SERPINH1 gene has been identified as a potential cause of premature delivery in African-American women. The variant reduces collagen production, making membranes more prone to rupture. This discovery may help physicians identify high-risk patients and prevent serious pregnancy complications.
Researchers at U-M's Life Sciences Institute discovered that the MT1-MMP gene regulates fat cell size and metabolic gene expression. In three-dimensional environments, the gene plays a critical role in adipocyte development, potentially leading to novel therapeutics for obesity prevention.
In the absence of MT1-MMP, preadipocytes fail to break through extracellular matrix, disrupting fat cell development. However, MT1-MMP is essential for remodeling the surrounding matrix to facilitate normal fat formation. The enzyme may also regulate collagen in white adipose tissue and act as a protein-degrading rheostat.
Researchers found that lampreys, long thought to be evolutionary outliers, use the same essential protein to build cartilage as all other vertebrates, including humans.
