چکیده

Acute promyelocytic leukemia (APL) is a well-defined entity among acute leukemia, cytogenetically characterized by a t(15;17) (q22;q11-12) translocation. In vitro and in vivo studies suggest that all-trans retinoic acid (RA) treatment restores cell maturation. We have isolated the first permanent cell line with t(15;17), derived from the marrow of a patient with APL in relapse. The establishment of the cell line, its morphologic, karyotypic, and immunohistochemical features are reported. RA induced cell line maturation. Cells strongly expressed myeloid markers, but also some T-cell markers. Additional karyotypic abnormalities, a 12p rearrangement and the possible presence of a homogeneous staining region (HSR) on 19q+ are discussed both in relation to T-cell (CD2, CD4) and monocyte (CD9) markers, and to the acquired cell growth autonomy. The cell line represents a remarkable tool for biomolecular studies.

The Antitumoral Activity of Zataria Multiflora Methanolic Extract on Acute Promyelocytic Leukemia Cell Line; NB4

Background & Objective:  Zataria multiflora is a plant that belongs to Laminaceae family. It is traditionally believed to have several therapeutic effects. Acute promyelocytic leukemia is a distinct subtype of acute myeloid leukemia with dominancy of promyelocytes in bone marrow and blood stream. The aim of this study is to investigate the anticancer effects of Z. multiflora extract on acute pr...

Targeting of PML/RARa Is Lethal to Retinoic Acid–Resistant Promyelocytic Leukemia Cells

Acute promyelocytic leukemia (APL) cells, containing the t(15;17) rearrangement, express the fusion protein, PML/ RARa. Clinically, patients respond to all-trans retinoic acid (ATRA) through complete remissions associated with myeloid maturation of leukemic cells. This clinical ATRA response of APL is linked to PML/RARa expression. Unfortunately, these remissions are transient and relapsed APL ...

Granulocytic differentiation of human NB4 promyelocytic leukemia cells induced by all-trans retinoic acid metabolites.

The metabolism of all-trans retinoic acid (ATRA) has been reported to be partly responsible for the in vivo resistance to ATRA seen in the treatment of human acute promyelocytic leukemia (APL). However, ATRA metabolism appears to be involved in the growth inhibition of several cancer cell lines in vitro. The purpose of this study was to evaluate the in vitro activity of the principal metabolite...

Background: One of the acute hematologic malignancies is acute promyelocytic leukemia (APL) that resulted in translocation of chromosomes 15 and 17, t (15; 17), and cessation in the maturation of myeloid cell line, and ultimate aggregation of neoplastic promyelocytes. Regarding that appetence of using herbal and marine medicine studies is increasing, and on the other hand, the features of Cassi...
