By Suneethi Sivakumaran Proposed mechanism of skin barrier formation. SDR9C7-catalyzed oxidation of linoleate in ceramides is required for covalent binding to the protein matrix and sealing of the water permeability barrier. Diagram courtesy of Alan Brash. Human skin has three major layers: epidermis, dermis, and hypodermis. Epidermis is the outermost… Read More

By Alexandra Fuller Model of vertebrate replication termination. Adapted with permission from Dewar et al. Nature 2018; 525:345–350. DOI: 10.1038/nature14887. You might break chicken eggs for your breakfast, but the lab of James Dewar (Biochemistry) breaks frog eggs to better understand the mechanisms cells use to terminate DNA replication. Published… Read More

By Cayetana Arnaiz Yépez Super-resolution images of two human epithelial cells. Fluorescence intensities are heatmapped to facilitate visualization; warmer colors correspond to higher levels of the cytoskeletal protein, actin. Image courtesy of Matt Tyska. Cells along our intestinal tract are responsible for absorbing nutrients and acting as a barrier to… Read More
