Selection and characterization of a novel agonistic human recombinant anti-Trail-R2 minibody with anti-leukemic activity
2009
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising natural anticancer therapeutic agent because through its “death receptors”, TRAIL-R1 and TRAIL-R2, it induces apoptosis in many transformed tumor cells, but not in the majority of normal cells. Hence, agonistic compounds directed against TRAIL death receptors have the potential of being excellent cancer therapeutic agents, with minimal cytotoxicity in normal tissues. Here, we report the selection and characterization of a new single-chain fragment variable (scFv) to TRAIL-R2 receptor isolated from a human phage-display library, produced as minibody (MB), and characterized for the in vitro anti-leukemic tumoricid…
Chaperonopathies and chaperonotherapy. Hsp60 as therapeutic target in cancer: potential benefits and risks.
2013
In this minireview we focus on Hsp60 as a target for anticancer therapy. We discuss the new concepts of chaperonopathies and chaperonotherapy and present information on Hsp60 localization in the cell membrane of human tumor cells. We describe novel mechanisms for Hsp60 reaching the extracellular environment that involve membrane-associated stages, as well as data on anti-Hsp60 antibodies found in human sera, both in normal subjects and patients affected by autoimmune diseases. Finally, we discuss possible therapeutic applications of anti-Hsp60 antibodies in cancer treatment, evaluating also side effects on non-tumor cells. In conclusion, the way for investigating Hsp60-targeted anti-tumor t…
Antitumor effects of novel co-drugs linking histone deacetylase and ribonucleotide reductase inhibitors in hematological tumors
2011
Combination therapy is the mainstay of anticancer therapy due to the significant synergistic effects achievable. Now that anticancer drug research turned toward a more molecular targeted approach, the design of dual-target drugs appears to be a new promising strategy with the potential to improve the therapeutic efficacy of the single drug and to reduce the probability of drug induced resistance and cross resistance. In our previous work, we found that 3’-C-methyl-adenosine (3’-Me-Ado), developed by us as a potent ribonucleotide reductase (RR) inhibitor with antitumor activity against both human leukemia and carcinoma cell lines, elicited significant growth inhibitory and apoptotic synergis…
