Liver-Directed Base Editing Of Abcc6 Prevents Ectopic Calcification In A Variant-Humanized Mouse Model Of Pseudoxanthoma Elasticum, Lauren C. Testa, Dora Obiri-Yeboah, Hooda Said, Ping Qu, Michael A. Levine, Mohamad-Gabriel Alameh, Kiran Musunuru, Qiaoli Li, Xiao Wang

Department of Biochemistry and Molecular Biology Faculty Papers

Pseudoxanthoma elasticum (PXE) is an autosomal recessive connective tissue disorder characterized by ectopic calcification of elastic fibers throughout the skin, retina, and arteries. It is caused by pathogenic variants in ABCC6 , which encodes a transmembrane transporter that primarily localizes to hepatocytes. Loss of ABCC6 function in hepatocytes leads to systemic deficiency of inorganic pyrophosphate (PPi), a potent inhibitor of calcification; such depletion of PPi from the circulation is responsible for multisystemic ectopic calcification seen in PXE. Therefore, liver-targeted variant correction by genome editing and subsequent restoration of systemic PPi may offer a one-and-done therapeutic approach for PXE. The ABCC6 …

Inflammaging And Cognitive Decline: A Brief Review Of The Chronic Low-Grade Neural Inflammation Hypothesis, Gage Pompa

Undergraduate Research Symposium Lightning Talks

This presentation reviews the chronic low‑grade neural inflammation hypothesis as a mechanism linking aging to cognitive decline. Inflammaging refers to persistent, low‑level inflammation that develops with age due to immune dysregulation in the absence of infection. In the brain, this process is often triggered by the accumulation of beta‑amyloid plaques and phosphorylated tau tangles. Microglia attempt to clear these proteins, but their prolonged activation releases inflammatory mediators that damage surrounding neurons. Over time, this sustained neural inflammation contributes to neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, epilepsy, and psychiatric disorders including schizophrenia and major depression. Imaging markers …
