Aug. 15, 2019, 10:50 AM   by Tom Wilemon It’s well established that chronic inflammation can lead to colon cancer, but the molecular mechanisms behind this association aren’t fully understood. Research at Vanderbilt University Medical Center into the role that the signaling protein SMAD4 plays in this process has received… Read More

Aug. 8, 2019, 10:00 AM by Bill Snyder DDR1 is a receptor tyrosine kinase (RTK) — a cell surface receptor — that regulates multiple functions including the maintenance of the normal structure of tissues, but which also contributes to pathological conditions including cancer, inflammation and fibrosis. In the kidney, upregulation of… Read More

Figure reproduced under the CC BY-NC-ND license from C. P. Nielsen, et al., Cell Rep., 28, 1074. The WNT family of signaling proteins plays an important role in the regulation of cell proliferation, differentiation, motility, and migration via multiple pathways that are frequently dysregulated in cancer. The well-known canonical WNT… Read More

Jul. 29, 2019, 8:30 AM by Bill Snyder The failure of pancreatic beta cells to release appropriate amounts of insulin in response to rising blood glucose levels is a hallmark of type 2 diabetes. During the past decade researchers have shown that microtubules — part of the cell’s… Read More
