This article is published with open access Abstract Maintenance of the pancreatic acinar cell phenotype suppresses tumor formation. Hence, repetitive acute or chronic pancreatitis, stress conditions in which the acinar cells dedifferentiate, predispose for cancer formation in the pancreas. Dedifferentiated acinar cells acquire a large panel of duct cell-specific markers. However, it remains unclear to what extent dedifferentiated acini differ from native duct cells and which genes are uniquely regulating acinar cell dedifferentiation. Moreover, most studies have been performed on mice since the availability of human cells is scarce. Here, we applied a non- fi 1234567890();,: 1234567890();,: genetic lineage tracing method of human pancreatic exocrine acinar and duct cells that allowed cell-type-speci c gene expression profiling by RNA sequencing. Subsequent to this discovery analysis, one transcription factor that was unique for dedifferentiated acinar cells was functionally characterized. RNA sequencing analysis showed that human dedifferentiated acinar cells expressed genes in “Pathways of cancer” with a prominence of MECOM (EVI-1), a transcription factor that was not expressed by duct cells. -

XL t(3;3) GATA2/ MECOM DF Translocation/Dual Fusion Order No.: Probe D-5124-100-OG Description XL t(3;3) GATA2/MECOM DF is designed as a dual fusion probe. The orange labeled probe spans the breakpoint at 3q26 (MECOM), the green labeled probe spans the breakpoint at 3q21 (GATA2 and RPN1). Clinical Details The chromosomal aberrations inv(3)(q21q26.2) and t(3;3)(q21;q26.2) characterize a distinct entity within patients with acute myeloid leukemia (AML). Their incidence in AML is about 1%-2.5% and patients have an unfavorable prognosis and low response to chemotherapy. Inv(3)/t(3;3) juxtapose the GATA2 enhancer with the MECOM locus which results in overexpression of EVI1. The EVI1 gene is located in 3q26 and is involved in hematopoietic stem cell maintenance.

While damaged renal tubular epithelial cells (RTECs) undergo reparative process to proliferate and replace the damaged epithelium, it is not a robust mechanism. The initial damage is followed by a cross-talk of innate immune system and RTECs resulting in exacerbation of inflammation, fibrosis, and sometimes irreversible damage. Despite the prevalence and severity of AKI, no FDA approved therapeutics exist to replace damaged or lost RTECS. Therefore, it is imperative to screen, identify, and understand mechanisms with which candidate therapeutics can enhance repair. -
