Abstract Estrogen receptor (ER) α is expressed in a subset of patient-derived acute myeloid leukemia (AML) cells, whereas Akt is predominantly expressed in most types of AML. Targeting AML with dual inhibitors is a novel approach to combat the disease. Herein, we examined a novel small molecule, 3-(4-isopropyl) benzylidene-8-ethoxy,6- methyl, chroman-4-one (SBL-060), capable of targeting AML cells by inhibiting ERα and Akt kinase. The chemical properties of SBL-060 were identified by proton nuclear magnetic resonance (¹ H-NMR), ¹³C-NMR, and mass spectroscopy. In silico docking was performed using an automated protocol with AutoDock-VINA. THP-1 and HL-60 cell lines were… More >

Abstract RAS-responsive element-binding protein 1 (RREB1) is a transcription factor that is implicated in RAS signaling and multiple tumors. However, the role of RREB1 in acute myeloid leukemia has not been studied. We found that RREB1 is overexpressed in AML patients and myeloid leukemia cell lines (NB4 and HL-60), and RREB1 expression was significantly decreased during granulocytic differentiation of myeloid leukemia cells induced by all-trans retinoic acid (ATRA). Then we performed a RREB1 knockdown assay in NB4 and HL-60 cells; the results showed that knockdown of RREB1 upregulated expression of CD11b, CEBP , and microRNA-145 (miR-145), More >

Abstract CXCL-12 and its receptor CXCR4 participate in breast cancer and melanoma cell metastasis to bone and lymphoid nodes. CD44, as a receptor for hyaluronic acid, is involved in lymphocyte recirculation, homing, adhesion and migration. But the role of CD44 in CXCL-12 induced leukemia cell migration still remains unclear. The present study showed that CXCL-12 stimulation induced the rapid internalization of CXCR4 and facilitated the formation of lamellipodia and uropod in acute leukemia cell line HL-60. CXCL12 also induced CD44 translocation into the uropod, while CD44 remained evenly distributed on the untreated cell membranes. Results suggest More >
