Finally! A human pancreatic β cell line.
For decades, investigators have made numerous attempts to generate human pancreatic β cell lines that could be used to advance β cell biology, facilitate drug discovery, and provide a pathway to β cell replacement therapy for the treatment of diabetes. In this issue of the JCI, Ravassard and colleagues report that this has finally been achieved successfully with a multistep process that led to ...
متن کاملDevelopment of a conditionally immortalized human pancreatic β cell line.
Diabetic patients exhibit a reduction in β cells, which secrete insulin to help regulate glucose homeostasis; however, little is known about the factors that regulate proliferation of these cells in human pancreas. Access to primary human β cells is limited and a challenge for both functional studies and drug discovery progress. We previously reported the generation of a human β cell line (Endo...
متن کاملCytotoxic effect of pyocyanin on human pancreatic cancer cell line (Panc-1)
Objective(s): Pyocyanin, a blue-green pigment produced by Pseudomonas aeruginosa, interferes with host redox cycles, which can lead to generation of reactive oxygen species and progressive cellular oxidative damage. The aim of this study was to assess the influence of pyocyanin on human pancreatic cancer cell line.Materials and Methods: Polymerase Chain Reaction (PCR) was applied to confirm the...
متن کاملA genetically engineered human pancreatic β cell line exhibiting glucose-inducible insulin secretion.
Despite intense efforts over the past 30 years, human pancreatic β cell lines have not been available. Here, we describe a robust technology for producing a functional human β cell line using targeted oncogenesis in human fetal tissue. Human fetal pancreatic buds were transduced with a lentiviral vector that expressed SV40LT under the control of the insulin promoter. The transduced buds were th...
متن کاملSMAD4-independent activation of TGF-β signaling by MUC1 in a human pancreatic cancer cell line
Pancreatic Ductal Adenocarcinoma (PDA) has a mortality rate that nearly matches its incidence rate. Transforming Growth Factor Beta (TGF-β) is a cytokine with a dual role in tumor development switching from a tumor suppressor to a tumor promoter. There is limited knowledge of how TGF-β function switches during tumorigenesis. Mucin 1 (MUC1) is an aberrantly glycosylated, membrane-bound, glycopro...
