In this podcast, authors Maria A. Ilomäki and Lauri Polari (both at Åbo Akademi University) discuss their recently published research titled “Defining a timeline of colon pathologies after keratin 8 loss: Rapid crypt elongation and diarrhea are followed by epithelial erosion and cell exfoliation.” New and Noteworthy: Understanding the order in which physiological and molecular events occur helps to recognize the onset of diseases and improve their preclinical models. We utilized Cre-Lox-based inducible keratin 8 deletion in mouse intestinal epithelium to characterize the earliest events after keratin 8 loss leading to colitis. These include diarrhea and crypt elongation, followed by erosion and neutrophil activity. The authors results also support noninvasive methodology for monitoring colon diseases in preclinical models.
