Abstract
Cell plasticity is a hallmark of cancer, enabling tumor cells to acquire multiple phenotypes responsible for tumor progression, metastasis, and therapy resistance. In this issue of the JCI, Kawai and colleagues leveraged genetically engineered mouse models (GEMM) of pancreatic ductal adenocarcinoma (PDAC) to demonstrate that loss of Pbrm1, a member of the SWI/SNF complex, drives dedifferentiation and aggressive tumor features. Pbrm1 loss activated a program of epithelial-to-mesenchymal transition (EMT) and allowed the emergence of poorly differentiated histologies that are commonly associated with high recurrence rate and dismal prognosis. These findings reveal the role of the SWI/SNF complex during PDAC evolution in maintaining cell identity and restraining the progression of this lethal disease.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
