  • I'm-Yunity acts selectively in HL-60 leukemic cells, resulting in cell cycle restriction through the G(1)/S checkpoint and the induction of apoptosis. (nih.gov)
  • Several assays are available to monitor apoptosis and other forms of cell death. (bmglabtech.com)
  • These and other assays are extremely good in evaluating apoptosis in a homogenous cell population, but are less useful when evaluating apoptosis in only one type of cell when a mixture of cells is present. (bmglabtech.com)
  • In the present study, we aimed to evaluate the effects of MTE on the proliferation and apoptosis of Jurkat cells (T-ALL lines) and lymphocytes from T-ALL (T-cell acute lymphoblastic leukemia) patients. (oncotarget.com)
  • Finally, MTE significantly inhibited the proliferation and promoted the apoptosis of lymphocytes from T-ALL patients, compared with lymphocytes from healthy peoples. (oncotarget.com)
  • Taken together, these results reveal an unrecognized function of MTE in inhibiting the proliferation and inducing the apoptosis of T-ALL cells, and identify a pathway of PTEN/PI3K/AKT/mTOR for the effects of MTE on leukemia therapy. (oncotarget.com)

  • As with any assay examining the function of immune cells in vitro , there are a number of important considerations to consider improving the performance of the experiment. (jove.com)
  • Most immune cells do not make new DNA unless they are activated, so a positive response is easily detectable against low background interference. (cytologicsbio.com)
