The KU-812E cell line is a notable hematopoietic cell line derived from a patient with acute myelogenous leukemia (AML). It was originally established in 1976 by Toru Itoh and colleagues at the Kawasaki Medical School in Japan. The cell line was derived from the KU-812 cell line, which was established from the peripheral blood of a patient with chronic myelogenous leukemia (CML). The transition to the KU-812E subline was achieved by continuous culture in the presence of phorbol ester, leading to the acquisition of characteristics resembling those of immature cells in AML.
In the context of molecular biology research, the KU-812E cell line has been extensively utilized due to its relevance in studying hematopoietic differentiation, leukemogenesis, and the molecular mechanisms underlying leukemia pathogenesis. Furthermore, its sensitivity to various pharmacological agents has rendered it a valuable tool for drug screening and therapeutic development in the field of leukemia research.
The GFP (Green Fluorescent Protein) reporter cell line, established using the KU-812E cells, incorporates a GFP expression cassette into the cellular genome. This reporter system allows for the visualization and quantification of gene expression or cellular processes through the detection of GFP fluorescence. The introduction of the GFP reporter into the KU-812E cell line provides a versatile platform for studying gene regulation, signal transduction pathways, and drug responses in the context of leukemia.
CML is primarily treated with TKIs like Imatinib, which inhibit the Bcr-Abl protein, improving patient survival. Researchers explored alternative strategies for treating CML due to current therapy limitations, notably TKIs. They investigated SMO inhibition within the Hedgehog signaling pathway. Using Cell Line KU-812, they tested SMO-inhibiting compounds, notably MRT92, observing reductions in Gli1 protein levels, increased Gli1 and SMO RNA levels, decreased cell proliferation, and induced apoptosis/autophagy. Additionally, these compounds modulated miRNAs associated with the Hedgehog pathway, suggesting SMO inhibition as a promising therapeutic target for CML, with potential as pathway antagonists.
Figure 1. SMO RNA expression in KU-812 cells was investigated by the researchers. The effects of compounds MRTX, MRT94, MRT92, MRT83, MRTY, and a control compound on SMO RNA expression after 24h (a) or 72h (b) treatment at 10 μM and after 24h (c) or 72h (d) treatment at 50 μM were assessed.
