background: acute myeloid leukemia (aml) is an immunophenotypically heterogeneous malignant disease, in which cd34 positivity is associated with poor prognosis. osteopontin (opn) plays different roles in physiologic and pathologic conditions like: survival, metastasis and cell protection from cytotoxic and apoptotic stimuli. due to anti-apoptotic effect of opn in normal and malignant cells, sil...

Doxycycline, a tetracycline-based antibiotic, has been reported to attenuate melanoma cell migration through inhibiting the focal adhesion kinase (FAK) signaling pathway. However, it remains to be elucidated whether doxycycline exerts this effect on leukemia cell migration. The present study aimed to examine the role of doxycycline in leukemia cell migration. The invasion capacities of the huma...

Acute myeloid leukemia (AML) is a heterogeneous and intrinsically resistant stem cell neoplasm, occurring in about 14 000 patients the US annually. AML characterized by unbridled proliferation of progenitor cells block normal differentiation. Unfortunately, despite recent advances treatment, prognosis poor for almost all older adults half under age 60. Thus, novel effective therapies are urgent...

chronic lymphocytic leukemia (cll) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. many ferula species, including f. asa-foetida, synthesize terpenyloxy coumarins. one of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines.     in this study induction of apoptosis by umbelliprenin ...

We have previously shown that leukemia-specific cytotoxic T cells (CTL) can be generated from the bone marrow of most patients with B-cell precursor acute leukemias. If these antileukemia CTL are to be used for adoptive immunotherapy, they must have the capability to circulate, migrate through endothelium, home to the bone marrow, and, most importantly, lyse the leukemic cells in a leukemia-per...

Many leukemia patients suffer from dysregulation of their immune system, making them more susceptible to infections and leading to general weakening (cachexia). Both adaptive and innate immunity are affected. The fruit fly Drosophila melanogaster has an innate immune system, including cells of the myeloid lineage (hemocytes). To study Drosophila immunity and physiology during leukemia, we estab...
