    © 2019 Elsevier B.V. There is strong demand for cell separation methods that do not decrease cell activity or modify cell surfaces. Here, new temperature-modulated cell-separation columns not requiring cell-surface premodification are described. The columns were packed with temperature-responsive cationic polymer hydrogel-modified silica beads. Poly(N-isopropylacrylamide-co-n-butyl methacrylate-co-N,N-dimethylaminopropyl acrylamide) hydrogels with various cationic moieties were attached to silica-bead surfaces by radical polymerization using N,Nʹ-methylenebisacrylamide as a crosslinking agent. The beads were packed into solid-phase extraction columns, and temperature-dependent cell elution from the columns was found using HL-60 and Jurkat cells. The retention HL-60 and Jurkat cells in columns containing cationic beads at 37 °C was 95.3% to 99.6% and 95.0% to 98.8%, respectively. By contrast, beads without cationic properties exhibited low cell retention (20.6% for HL-60 and 32.5% for Jurkat cells). The cells were mainly retained through both electrostatic and hydrophobic interactions. The retained HL-60 (4.9%) and Jurkat cells (40%) were eluted at 4 °C from the column with a low composition of cationic monomer (DMAPAAm, 1 mol% in copolymer), because the temperature-responsive hydrogels on the beads became hydrophilic, decreasing the hydrophobic interactions between the cells and the beads. A higher number of Jurkat cells than HL-60 cells were eluted because of differences in their electrostatic properties (Jurkat cells: −2.53 mV; HL-60 cells: −20.7 mV). The results indicated that cell retention by the hydrogel-coated beads packed in a solid phase extraction column could be modulated simply by changing the temperature.

    © 2019 To date, the prognosis of multiple myeloma (MM) in patients harboring cytogenetic abnormalities (CA) involving t (4; 14) and deletion of chromosome 17 remains poor despite recent advances in drug development that include the use of immunomodulatory drugs (IMiDs) such as lenalidomide for MM. To address this issue, we have developed a novel phenylphthalimide derivative, TC11, that is structurally related to IMiDs. It remains unclear how TC11 induces apoptosis of MM cells with high-risk CA. Here, we show that TC11 does not induce degradation of CRBN's substrates, IKZF1/3 and CK1α, and induces apoptosis of CRBN-silenced MM; this effect was independent of the cereblon (CRBN) pathway, which is involved in the mechanism of action of IMiDs used for the treatment of MM. We also revealed that TC11, in contrast to existing IMiDs, induced degradation of MCL1 and activation of caspase-9. Furthermore, inhibition of CDK1 by CGP74514A prevented TC11-induced MCL1 degradation, caspase-9 activation, and the subsequent apoptotic cell death. We showed that ectopic MCL1 expression rescued apoptosis of MM. These observations suggest that TC11 induces apoptotic death caused by degradation of MCL1 during prolonged mitotic arrest. Therefore, our findings suggest that TC11 is a potential drug candidate for high-risk MM.

  • A novel derivative (GTN024) from a natural product, komaroviquinone, induced the apoptosis of high-risk myeloma cells via reactive oxygen production and ER stress.
