pancreatic cells

[Biological Trace Element Research] Scientists found that EPCAM + tumors developed in the mouse pancreas store zinc that is detectable by fluorescence-activated cell sorting using N-(6-methoxy-8-quinolyl)-p-toluenesulfonamide (TSQ), a fluorescence chelator. EPCAM + TSQ + tumor cells isolated from the mouse pancreas formed organoids in matrigel.

[Nutrition and Cancer-An International Journal] Human pancreatic cancer cells MIA-Pa-Ca-2 were treated with the phytochemicals alone or their equimolar mixture for 24 h and activation of Nrf2 and expression of its target genes were evaluated.

[Biological Trace Element Research] Upon treatment with N,N,N′,N′-tetrakis(2-pyridinylmethyl)-1,2-ethanediamine, a zinc chelator, organoids degenerated and its negative effect was rescued by co-treatment with zinc, indicating that zinc is necessary for the growth and survival of tumor organoids.

[Cell Death & Disease] To search other possible mechanisms, scientists found the mRNA level and protein level of MKP7 (a phosphatase for phospho-JNK) were dramatically reduced in pancreatic β cells in the islets from NR4A1 knockout mice compared with that from wild type mice.

[Biochemical Genetics] Min6 cells were induced by 5 mg/dl UA and the cell proliferation, apoptosis, and insulin release were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry and glucose-stimulated insulin secretion, respectively.

[Nature Biomedical Engineering] Researchers showed that forced expression of C-X-C chemokine receptor type 6 in antigen-specific T cells enhanced the recognition and lysis of pancreatic cancer cells and the efficacy of adoptive cell therapy for pancreatic cancer.
