TL;DR: This in vitro HR myeloma cell model will be useful for investigating MM cell-endothelial cell interactions under hypoxic conditions, which may mimic the in vivo bone marrow microenvironment.

TL;DR: Bioinformatic analysis of the quantitative proteomics phenotypes revealed that Hepa1–6 cells were deficient in mitochondria, reflecting re-arrangement of metabolic pathways, drastically up-regulate cell cycle-associated functions and largely shut down drug metabolizing enzymes characteristic for the liver.

TL;DR: Preliminary studies found that the transforming factor was found to be sensitive to heat and ether, was sedimented at 70,000 × g and retained by a filter of APD 50 mμ; these results are compatible with the herpes‐like virus of the QIMR‐WIL cells being the transforming factors.
Abstract: Transformation of foetal human leukocytes followed inoculation with a filtrate of cells of the QIMR-WIL human leukocyte cell line, previously shown to carry a herpes-like virus. Proliferation of leukocytes was generally noted 24–35 days after inoculation, and resulted in the establishment of cell lines resembling those derived from peripheral leukocytes of patients with leukaemia or infectious mononucleosis. The sex of representative transformed lines confirmed that they were of foetal origin. Transformation occurred with two separate filtrates of QIMR-WIL cells, with leukocytes from five individual foetuses, and with leukocytes from bone marrow, thymus and spleen. Various control inocula gave negative results, including culture medium and filtrates of Raji and QIMR-GOR cell lines. Representative transformed lines were found to fix complement with human serum known to react with QIMR-WIL and QIMR-GOR cells; but similar serum showed little evidence of reaction by immunofluorescence. The transformed cell lines studied appeared to be essentially diploid, and subterminal constrictions involving Group C chromosomes were noted in a small proportion of cells in 8/9 lines. In preliminary studies, the transforming factor was found to be sensitive to heat and ether, was sedimented at 70,000 × g and retained by a filter of APD 50 mμ; these results are compatible with the herpes-like virus of the QIMR-WIL cells being the transforming factor.

TL;DR: The isolation and successful propagation of neural progenitor cells from human postmortem tissues and surgical specimens are described and may extend the application of these progenitors cells in the treatment of neurodegenerative diseases.
Abstract: Culturing neural progenitor cells from the adult rodent brain has become routine1,2 and is also possible from human fetal tissue3,4, but expansion of these cells from postnatal and adult human tissue, although preferred for ethical reasons, has encountered problems5,6,7,8. Here we describe the isolation and successful propagation of neural progenitor cells from human postmortem tissues and surgical specimens. Although the relative therapeutic merits of adult and fetal progenitor cells still need to be assessed, our results may extend the application of these progenitor cells in the treatment of neurodegenerative diseases.

TL;DR: IAP treatment of NG108-15 cells caused specific uncoupling of negative signal transduction from inhibitory receptors to the adenylate cyclase catalytic unit via the guanine nucleotide regulatory protein, as a result of ADP-ribosylation of one of the subunits of the regulatory protein.
