Background: Hypertensive nephropathy is one of the major causes of ESRD. Exercise has been considered a nonpathological therapy for hypertension and its complications, yet mechanisms remain unclear. We sought to investigate whether periodic swimming could ameliorate hypertension-induced kidney dysfunction and its underlying mechanisms. Read More

Renal fibrosis is the common pathological hallmark of chronic kidney disease, and SET domain containing lysine methyltransferase 7 (SETD7) promote considerably renal fibrosis. However, the signaling mechanisms underlying SETD7 driving renal fibrosis are not fully understood. Here, we investigated the role of SETD7 in M2 macrophages-myofibroblasts transition and the myeloid fibroblasts activation in folic acid and obstruction-induced renal fibrosis. Read More

Endothelial cells are important in the maintenance of healthy blood vessels and in the development of vascular diseases. However, the origin and dynamics of endothelial precursors and remodeling at the single-cell level have been difficult to study in vivo due to technical limitations. We aimed to develop a direct visual approach to track the fate and function of single endothelial cells over several days-weeks in the same vascular bed in vivo using multiphoton microscopy (MPM) of transgenic Cdh5-Confetti mice and the kidney glomerulus as a model.

Throughout the world, including the United States, men have worse outcomes from COVID-19 than women. SARS-CoV-2, the causative virus of the COVID-19 pandemic, uses angiotensin-converting-enzyme-2 (ACE2) to gain cellular entry. ACE2 is a member of the renin-angiotensin-system (RAS) and plays an important role in counteracting the harmful effects mediated by the angiotensin-type-1-receptor. Read More

Single amino acid substitutions within protein structures often manifest with clinical conditions in humans. The mutation of a single amino can significantly alter protein folding and stability, or change protein dynamics to influence function. The chemical engineering field has developed a large toolset for predicting the influence of point mutations with the aim of guiding the design of improved and more stable proteins. Read More
