Balanced chromosomal translocations that generate chimeric oncoproteins are considered to be initiating lesions in the pathogenesis of acute myeloid leukemia. The most frequent is the t(15;17)(q22;q21), which fuses the PML and RARA genes, giving rise to acute promyelocytic leukemia (APL). An increasing proportion of APL cases are therapy-related (t-APL), which develop following exposure to radi...

LNCaP, DU145, and PC3 prostate carcinoma cells secrete the 27-kDa soluble Fas ligand (sFasL) into their local environment. sFasL arises from the 40-kDa membrane-bound form (mFasL), which can be found on the cell surface in the LNCaP line, as demonstrated by monoclonal antibody staining. mFasL was also found in extracts of all three cell lines, as demonstrated by Western blotting. FasL mRNA was ...

PURPOSE The pipecolinate derivative VX-710 (biricodar; Incel) is a clinically applicable modulator of P-glycoprotein (Pgp) and multidrug resistance protein (MRP-1); we studied its activity against the third multidrug resistance (MDR)-associated drug efflux protein, breast cancer resistance protein (BCRP). EXPERIMENTAL DESIGN VX-710 modulation of uptake, retention, and cytotoxicity of mitoxant...

Metronomic chemotherapy with cytotoxic agents has been shown to inhibit angiogenesis and, consequently, tumor growth by targeting vascular endothelial cells (ECs). In these regimens, anti-tumor activities additional to anti-angiogenesis may operate. Moreover, chemotherapy typically generates reactive oxygen species in targeted ECs, which can affect angiogenesis. The aim of the present study was...

UNLABELLED The outcomes of Central Nervous System (CNS) relapses in children with acute lymphoblastic leukaemia (ALL) treated in the ALL R3 trial, between January 2003 and March 2011 were analysed. Patients were risk stratified, to receive a matched donor allogeneic transplant or fractionated cranial irradiation with continued treatment for two years. A randomisation of Idarubicin with Mitoxant...

PURPOSE ABCG2 is a putative marker of progenitor cells, including the corneal epithelium. The authors investigated whether ABCG2 functions in the homeostasis of corneal epithelial cells using abcg2 knockout (KO) mice and corneal epithelial cell lines. METHODS abcg2 KO mice and a spontaneously immortalized murine corneal epithelial cell line (TKE2) were used for experiments. Flow cytometry was...

Mitoxantrone (MTX) 1, 4–dihydroxy–5, 8–bis [[2–[2–hydroxyethyl) amino] amino]–9, 10– anthracenedione is, clinically well established anthracycline class of anticancer drug. Till today no structural details confirm the interaction of mitoxantrone with its receptor site i.e. DNA Although it has been proposed and confirmed that drug binds to DNA specifically at 5’-CpG-3’ site and flanking sequence...

BACKGROUND Multiple sclerosis (MS) is a central nervous system disorder with periods of recurrence and recovery. Mitoxantrone has been approved for secondary progressive MS (SPMS) treatment but data lacks the role of corticosteroid pulse therapy in SPMS. OBJECTIVES To evaluate the role of corticosteroid pulse therapy in patients with SPMS receiving mitoxantrone. PATIENTS AND METHODS A doubl...

Triterpene saponosides are widely distributed plant secondary metabolites characterized by relatively low systemic cytotoxicity and a range of biological activities. These include anti-inflammatory, antimicrobial, vasoprotective and antitumor properties. In particular, the ability of saponins to enhance the cytotoxicity of chemotherapeutic drugs opened perspectives for their application in comb...

A sterically stabilized, mitoxantrone-loaded liposome, tailored to target luteinizing hormone-releasing hormone (LHRH) receptor overexpressing cells, was developed to promote the efficiency of intracellular delivery of mitoxantrone through receptor-mediated endocytosis. Liposomes were prepared by lipid film hydration and an ultrasound dispersion process. Thiolated gonadorelin with affinity for ...
