Here, we present a collection of 2,6,9-trisubstituted purines with nanomolar potency against PDGFRα and strong and selective cytotoxicity in the human eosinophilic leukaemia cell line EOL-1 that expresses the FIP1L1-PDGFRA oncogene.

Most notably, chromosomal rearrangements, such as FIP1L1-PDGFRA fusions caused by internal deletions in chromosome 4, are now known to be associated with many chronic eosinophilic leukemias.

To investigate the conservation of CIN in mCP mutants, we focused on FIP1L1, the human ortholog of yeast FIP1, a conserved mCP component that is part of an oncogenic fusion in eosinophilic leukemia.

FIP1L1-PDGFRalpha D842V, a novel panresistant mutant, emerging after treatment of FIP1L1-PDGFRalpha T674Ieosinophilic leukemia with single agent sorafenib.
Here, we report that a human eosinophilic leukemia cell line, EoL-1, and human peripheral blood (PB) eosinophils become reactive to the lymphoid chemokines CCL21 and CCL25 upon stimulation.
Apoptosis induction by retinoids in eosinophilic leukemia cells: implication of retinoic acid receptor-alpha signaling in all-trans-retinoic acid hypersensitivity.

As far as prognosis of these disease variants is concerned, hypereosinophilic syndrome patients with the FIP1L1-PDGFRalpha fusion gene may develop acute myelogenous (eosinophilic) leukemia, whereas those with clonal interleukin-5-producing T-cells have an increased risk of developing T-cell lymphoma.
The FIP1L1-PDGFRA fusion gene is generated by a cryptic interstitial chromosomal deletion, del(4)(q12q12), which indicates that these cases are clonal hematopoietic malignancies and should be reclassified as chronic eosinophilic leukemias based on current World Health Organization recommendations.

Tumour necrosis factor-alpha-induced expression of intercellular adhesion molecule-1 on human eosinophilic leukaemia EoL-1 cells is mediated by the activation of nuclear factor-kappaB pathway.
Differential and constitutive expression of the DRB1 and DRA gene products controls the surface HLA-DR expression level in human eosinophilic leukaemia cell lines.

The direct effect of interferon-gamma on human eosinophilic leukemia cell lines: the induction of interleukin-5 mRNA and the presence of an interferon-gamma receptor.
We report here that differentiation of a human eosinophilic leukaemia cell line, EoL-1, by sodium n-butyrate is associated with induction of PAF receptor gene expression, as indicated by: PAF receptor mRNA accumulation; increases in the binding of [3H]WEB 2086, a PAF antagonist; analysis of cell-surface expression of PAF receptor protein using a monoclonal anti-(PAF receptor) antibody; and augmentation of PAF-induced increase in the intracellular concentration of calcium.
A human cDNA encoding a putative G protein-coupled receptor designated chemokine beta receptor-like 1 (CMKBRL1) was isolated from an eosinophilic leukemia library.
