Molecular cytogenetic analysis consistently identifies translocations involving chromosomes 1, 2 and 15 in five embryonal rhabdomyosarcoma cell lines and a PAX-FOXO1A fusion gene negative alveolar rhabdomyosarcoma cell line.
(2001-01)Rhabdomyosarcoma in children is a "small round blue cell tumour" that displays skeletal muscle differentiation. Two main histological variants are recognised, alveolar (ARMS) and embryonal (ERMS) rhabdomyosarcoma. Whereas ... -
Dominant negative knockout of p53 abolishes ErbB2-dependent apoptosis and permits growth acceleration in human breast cancer cells
(2002)Dominant negative knockout of p53 abolishes ErbB2-dependent apoptosis and permits growth acceleration in human breast cancer cells. We previously reported that the FrbB2 oncoprotein prolongs and amplifies growth factor ... -
A G-quadruplex-interactive potent small-molecule inhibitor of telomerase exhibiting in vitro and in vivo antitumor activity
(AMER SOC PHARMACOLOGY EXPERIMENTAL THERAPEUTICS, 2002-05)The telomerase complex is responsible for telomere maintenance and represents a promising cancer therapeutic target. We describe herein the antitelomerase and antitumor properties of a small-molecule compound designed by ... -
A rationale for the clinical development of the thymidylate synthase inhibitor ZD9331 in ovarian and other solid tumours
(2002-07-18)A rationale for the clinical development of the thymidylate synthase inhibitor ZD9331 in ovarian and other solid tumours. ZD9331 is an antifolate drug that potently and specifically inhibits thymidylate synthase (TS). In ... -
Viral delivery of P450 reductase recapitulates the ability of constitutive overexpression of reductase enzymes to potentiate the activity of mitomycin C in human breast cancer xenografts
(2003)Viral delivery of P450 reductase recapitulates the ability of constitutive overexpression of reductase enzymes to potentiate the activity of mitomycin C in human breast cancer xenografts. Indolequinones such as mitomycin ... -
Technology evaluation: EMD-273063, EMD Lexigen
(2004)Technology evaluation: EMD-273063, EMD Lexigen EMD-273063 is an antibody/cytokine fusion protein comprised of a humanized version of the murine anti-GD2 antibody 14.18 coupled to two molecules of IL-2. It is being developed ... -
Molecular cytogenetic study of a mantle cell lymphoma with a complex translocation involving the CCND1 (11q13) region
(2004)We describe a progressive mantle cell lymphoma (MCL) in which multicolor fluorescence in situ hybridization (M-FISH) on metaphases did not detect the characteristic t(11;14)(q13;q32), although translocations of chromosomes ... -
Evaluation of by disubstituted acridone derivatives as telomerase inhibitors: the importance of G-quadruplex binding
(2004)The synthesis and evaluation of a group of 2,6-, 2,7- and 3,6-bis-aminoalkylamido acridones are reported, which show a similar level of activity against telomerase in vitro compared to their acridine counterparts. Computer ... -
Mechanism of activation of the RAF-ERK signaling pathway by oncogenic mutations of B-RAF.
(2004-03)Over 30 mutations of the B-RAF gene associated with human cancers have been identified, the majority of which are located within the kinase domain. Here we show that of 22 B-RAF mutants analyzed, 18 have elevated kinase ... -
Significant differences in biological parameters between prodrugs cleavable by carboxypeptidase G2 that generate 3,5-difluoro-phenol and -aniline nitrogen mustards in gene-directed enzyme prodrug therapy systems.
(2004-05)Nine new nitrogen mustard compounds derived from 2,6-difluoro-4-hydroxy- (3a-e) and 2,6-difluoro-4-amino- (4a-d) aniline were synthesized as potential prodrugs. They were designed to be activated to their corresponding ... -
Discovery of small molecules as anticancer agents: the role of the medicinal chemist in the discovery of new cancer therapeutics

PLCgamma1 is essential for early events in integrin signalling required for cell motility.
(2005-06)Cell motility is a critical event in many processes and is underlined by complex signalling interactions. Although many components have been implicated in different forms of cell migration, identification of early key ... -
Benzodithiophenes potentiate differentiation of acute promyelocytic leukemia cells by lowering the threshold for ligand-mediated corepressor/coactivator exchange with retinoic acid receptor alpha and enhancing changes in all-trans-retinoic acid-regulated gene expression.
(2005-09)Differentiation induction is an effective therapy for acute promyelocytic leukemia (APL), which dramatically responds to all-trans-retinoic acid (ATRA). Recent studies have indicated that combinatorial use of retinoid and ... -
Pharmacokinetic-pharmacodynamic relationships for the heat shock protein 90 molecular chaperone inhibitor 17-allylamino, 17-demethoxygeldanamycin in human ovarian cancer xenograft models.
(2005-10)PURPOSE: To establish the pharmacokinetic and pharmacodynamic profile of the heat shock protein 90 (HSP90) inhibitor 17-allylamino, 17-demethoxygeldanamycin (17-AAG) in ovarian cancer xenograft models. EXPERIMENTAL DESIGN: ... -
Targeting of multiple signalling pathways by heat shock protein 90 molecular chaperone inhibitors.
(2006-12)The last decade has seen the molecular chaperone heat shock protein 90 (HSP90) emerge as an exciting target for cancer therapy. This is because HSP90 is involved in maintaining the conformation, stability, activity and ... -
Calmodulin-independent, agonistic properties of a peptide containing the calmodulin binding site of estrogen receptor alpha
(2007-03-30)Calmodulin (CaM) contributes to estrogen receptor alpha (ER)-mediated transcription. In order to study the underlying mechanisms, we synthesized a peptide including the CaM binding site: ERalpha17p (P(295)-T(311)). This ... -
Multifaceted dysregulation of the epidermal growth factor receptor pathway in clear cell sarcoma of the kidney.
