Although down-regulation of WNT5A expression has been reported in some types of leukaemias, the level of WNT5A expression has not been assessed in leukaemia complete remission (CR) cases, the relationship among WNT5A expression level, the status of its promoter methylation, and the curative effect of leukaemia has not been reported, and the effect of WNT5A on cell proliferation has not been ass...

This study describes the establishment of two permanent leukemic B-cell lines (BALM-1 and -2) originating from the blood cells of a patient with a B-cell type of acute lymphoblastic leukemia. The cells of BALM-1 and -2 exhibited cell surface markers compatible with B-cell origin. The identity between the leukemic cells in vivo and those of the BALM lines was established on the basis of the kary...

    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 umbellipre...

BACKGROUND Although deferasirox (DFX) is reported to have anti-tumor effects, its anti-leukemic activity remains unclear. We evaluated the effect of DFX treatment on two murine lymphoid leukemia cell lines, and clarified the mechanisms underlying its potential anti-leukemic activity. METHODS L1210 and A20 murine lymphoid leukemia cell lines were treated with DFX. Cell viability and apoptosis ...

BACKGROUND Wnt/beta-catenin signaling is involved in the growth of various types of cancer cells. Wnt3A has been reported to promote the self-renewal of hematopoietic stem cells. MATERIALS AND METHODS The effects of recombinant Wnt3A protein on the in vitro growth of four acute myeloid leukemia (AML) and four acute T-lymphoblastic leukemia (T-ALL) cell lines was examined. RESULTS Wnt3A stim...

Human T-cell leukemia virus type I (HTLV-I) is an etiologic agent of adult T-cell leukemia (ATL). The viral protein Tax induces the activation and nuclear translocalization of transcription factor NF-kB, which is proposed to play a crucial role in the transformation of T cells by HTLV-I. However, the HTLV-I genes including Tax are not expressed significantly in primary leukemic cells from ATL p...

herein we describe a case of intraocular melanoma in a17-year old leukemic patient.   the history, histological findings of the enucleated eye, blood and bone marrow of the patient were investigated. the enucleated eye contained epitheloid cell type melanoma instead of leukemic cell infiltration.  we conclude that intraocular malignant melanoma can occur in acute lymphoblastic leukemia.
