In this newest study from the laboratory of Gus Mouneimne, PhD, recently-graduated CMM student Julieann Puleo and colleagues discovered that EVL, the Ena/VASP protein, is crucial for actin polymerization at focal adhesions (FAs). Importantly, they determined that EVL-mediated FA actin polymerization regulates FA maturation and mechanosensing, which are significant steps in mechanically-directed motility and durotactic invasion. This work is a significant contribution to our understanding of how cells interact with their microenvironment in normal and pathological contexts. PMID: 31594807
We are (fortunately) not alone. Microbes should no longer be seen as foes that need to be eliminated at all costs. Work from Donata Vercelli, PhD's laboratory recently featured in the Washington Post shows that living in traditional farming environments means living in a place that is extremely rich in microbes — the right microbes that our immune system has evolved to live with and learn from. The constellation of organisms found in soil and on farm animals programs how a child responds to allergens throughout her lifetime. This programming likely starts in utero and continues to shape the immune system during the first few years of life. Read more here.
A majority of the human genome consists elements called transposable elements – the fossils of evolutionary battles between ancient viruses and their human hosts. The human genome silences these elements by creating a specialized structure called heterochromatin on top of them. Dr. Keith Maggert and graduate student Farah Bughio's study in PNAS shows that heterochromatin is not as stable and reliable a protector as was previously thought, and instead turns on and off randomly and repeatedly throughout life, allowing transposable elements the freedom to once again move around the genome and cause damage.

Asthma and COPD are the most commonly diagnosed chronic lung diseases in the United States. While it is now recognized that a percentage of severe asthmatics develop fixed airway obstruction, little is known pertaining to the basic underlying mechanisms of this progression. Julie Ledford, PhD and her research team will examine the role of club cell secreted protein (CC16) in the context of airway infection as a previously overlooked link in understanding this progression. These studies may provide a novel therapeutic approach for treating individuals with low circulating CC16 in order to prevent lung function decline over time.
Anne Cress, PhD, and Gregory Rogers, PhD, received the prestigious NCI Provocative Questions Initiative grant to study molecular mechanisms of genomic alterations that contribute to early stages of prostate cancer initiation and progression. As co-PIs of this multi-PI (MPI) award, they lead an investigative team that includes Drs. Noel Warfel and Ray Nagle to investigate a link between hypoxia and organelle instability.
Curtis Thorne, PhD, Assistant Professor in the Department of Cellular and Molecular Medicine, and doctoral student Carly R. Cabel recently undertook an ambitious study to determine whether therapeutic targeting of LRP6 – a cell-surface receptor protein that mediates cell growth of its surrounding tissue environment - was a suitable treatment strategy for colon cancer, thus challenging the current scientific dogma and approaches to patient care. The results of Dr. Thorne and Ms. Cabel's experiments were published in a letter in the June 2019 issue of Developmental Cell. Read more here. PMID: 31211991
