PURPOSE Treatment of neuroblastoma is successful in less than half of patients with high-risk disease. The antitumor activity of a water soluble pegylated SN38 drug conjugate, EZN-2208, was compared with CPT-11 (a prodrug for SN38) in preclinical models of human neuroblastoma. EXPERIMENTAL DESIGN The in vitro cytotoxicity of EZN-2208 was tested by counting trypan blue dye- and Annexin V-posit...
The B-subunit of the bacterial Shiga toxin (STxB), which is nontoxic and has low immunogenicity, can be used for tumor targeting of breast, colon, and pancreatic cancer. Here, we tested whether human gastric cancers, which are among the most aggressive tumor entities, express the cellular receptor of Shiga toxin, the glycosphingolipid globotriaosylceramide (Gb3/CD77). The majority of cases show...
The E2F family of transcription factors, in partnership with DP proteins, is thought to regulate transcription of genes that encode protein products that are required for DNA synthesis, which include important cancer chemotherapeutic targets such as thymidylate synthase and dihydrofolate reductase. This study was conducted to investigate the effects of overexpression of human E2F-1 cDNA on chem...
In this in vitro study, we determined whether masitinib could reverse multidrug resistance (MDR) in cells overexpressing the ATP binding cassette subfamily G member 2 (ABCG2) transporter. Masitinib (1.25 and 2.5 µM) significantly decreases the resistance to mitoxantrone (MX), SN38 and doxorubicin in HEK293 and H460 cells overexpressing the ABCG2 transporter. In addition, masitinib (2.5 µM) sign...
Chemotherapies for colon cancer have recently advanced. However, there is still a need to develop agents and identify effective regimens for better treatments of colon cancer. Histone deacetylase inhibitors (HDACIs) have shown potential as anti-cancer agents. We investigated the anti-tumor effects of CG2 (an HDACI) in combination with irinotecan, 5-FU, or oxaliplatin. Combinations of CG2 with S...
