Gene regulatory networks that govern hematopoietic stem cells (HSCs) and leukemia-initiating cells (L-ICs) are deeply entangled. Thus, the discovery of compounds that target L-ICs while sparing HSC is an attractive but difficult endeavor. Presently, most screening approaches fail to counter-screen
Cytokinins are important purine derivatives that act as hormones to control many processes in plants. Cytokinins such as isopentenyladenine (IPA), kinetin and benzyladenine were very effective at inducing the granulocytic differentiation of human myeloid leukemia HL-60 cells. The metabolism of
Although differentiation therapy for patients with acute promyelocytic leukemia (APL) using all-trans retinoic acid (ATRA) has now been established, acute myeloid leukemia (AML) patients with other than APL only show a limited clinical response to ATRA. We must consider novel therapeutic drugs
Cytokinins are important purine derivatives that act as redifferentiation-inducing hormones to control many processes in plants. Cytokinins such as isopentenyladenine (IPA) and kinetin are very effective at inducing the granulocytic differentiation of human myeloid leukemia HL-60 cells. We examined
The cytotoxicity of two plant hormone compounds, kinetin and kinetin riboside, was studied on tumour cells, by colony forming assay with increased amount of cytotoxic molecules. The concentration of inhibitor required to reduce cell growth to 50% was determined for these molecules. Kinetin riboside
There is individual variation in the course of disease development and response to therapy of patients with chronic lymphocytic leukemia (CLL). Novel treatment options for CLL include a new generation of purine analogs, antibodies and inhibitors of specific cell signaling pathways, which typically
We examined the effects of various adenine analogues on the growth and differentiation of human myeloid leukemia HL-60 cells. Some of these analogues inhibit growth and induce nitroblue tetrazolium reducing activity in HL-60 cells. Cytokinins such as kinetin, isopentenyladenine, and benzyladenine
Cytokinins and cytokinin nucleosides are purine derivatives with potential anticancer activity. N(6)-furfuryladenosine (FAdo, kinetin-riboside) displays anti-proliferative and apoptogenic activity against various human cancer cell lines, and FAdo has recently been shown to suppress tumor growth in
Cytokinins and cytokinin nucleosides are purine derivatives with potential anticancer activity both in vitro and in vivo. N(6)-furfuryladenosine (kinetin riboside, KR) displays antiproliferative and apoptogenic activity against various human cancer cell lines and has recently been shown to suppress
