Pancreatic ductal adenocarcinoma (PDA) initiates from quiescent acinar cells that attain a Kras mutation, lose signaling basic helix-loop-helix (bHLH) transcription factors, undergo acinar-ductal metaplasia, and rapidly acquire increased growth potential. We queried whether PDA can be reprogrammed to revert their original cell state by shifting key programs.Human lines were engineered express an inducible form of the bHLH protein E47. Gene expression, growth, functional studies investigated...

To report the outcomes of Descemet membrane endothelial keratoplasty (DMEK) using a large diameter graft in management decompensation buphthalmic eyes.Four eyes 4 adults (1 man, 3 women) with bullous keratopathy and buphthalmos secondary to congenital glaucoma were treated DMEK posterior lamellar grafts diameters ranging from 10 12 mm. The mean age was 31 (±9) years (range, 20-38 years). Mean follow-up time 13.5 (±7.5) months 6-24 months). Main outcome measures best-corrected visual acuity...

Abstract Pancreatic Ductal Adenocarcinoma (PDA) is the most lethal form of cancer with an average survival merely 6 months, underscoring need for new therapeutic approaches. A central feature PDA progression reduced expression and activity basic helix-loop-helix (bHLH) transcription factors. Recently, we showed that restoring bHLH in highly aggressive cells, through overexpression factor E47, resulted growth arrest tumorigenicity. Cell cycle exit was characterized by Aurora kinase A, cyclin...
