The authors identified valosin-containing protein as a regulator of p53-R273H by conducting immunoprecipitation-tandem mass spectrometry analysis. VCP bound p53-R273H at its DNA binding domain.
The effects of conditioned medium collected from dedifferentiated adipocytes on pancreatic cancer cell proliferation, motility, metastasis and epithelial-mesenchymal transition (EMT) were evaluated by western blot analysis, colony forming, real-time cell analysis, 5-ethynyl-2’-deoxyuridine, immunofluorescence, Transwell and wound healing assays in vitro.

Investigators found that high expression of miR-194-5p in human pancreatic cancer patients is associated with a better survival rate, while increased expression of programmed cell death ligand 1 in human pancreatic cancer patients is associated with a worse survival rate.
Researchers observed for the first time that miR-33a-5p expression level was significantly decreased in pancreatic ductal adenocarcinoma tissues and cell lines.

Investigators discuss and focus on the pathological and molecular features of precancerous lesions of the pancreas, including pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, which are target lesions of early detection approaches.
