Delocalized lipophilic cations selectively target the mitochondria of carcinoma cells.
Traditional chemotherapies, aimed at DNA replication in rapidly dividing cells, have achieved only limited success in the treatment of carcinomas due largely to their lack of specificity for cells of tumorigenic origin. It is important, therefore, to investigate treatment strategies aimed at novel cellular targets that are sufficiently different between normal cells and cancer cells so as to pr...
متن کاملDelocalized lipophilic cations as a new therapeutic approach in cancer
Delocalized lipophilic cations (DLCs) penetrate plasma and mitochondrial membranes and accumulate in mitochondria. The higher mitochondrial membrane potentials of neoplastic vs normal cells, in general, account for greater uptake and may be a way to selectively target these cells since. Dequalinium (DQA) is a DLC and so our goal is to evaluate the therapeutic potential of DQA in cancer, namely ...
متن کاملPhoto-activation of the delocalized lipophilic cation D112 potentiates cancer selective ROS production and apoptosis
Delocalized lipophilic cations (DLCs) selectively accumulate in cancer cell mitochondria and have long been explored for therapeutic applications. Although targeted effects to cancer cells are demonstrated in vitro, non-specific toxicities in vivo have hampered clinical development. Identifying the molecular mechanisms of action and enhancing selectivity are thus necessary next steps to improve...
متن کاملTargeting peptide nucleic acid (PNA) oligomers to mitochondria within cells by conjugation to lipophilic cations: implications for mitochondrial DNA replication, expression and disease.
The selective manipulation of mitochondrial DNA (mtDNA) replication and expression within mammalian cells has proven difficult. One promising approach is to use peptide nucleic acid (PNA) oligomers, nucleic acid analogues that bind selectively to complementary DNA or RNA sequences inhibiting replication and translation. However, the potential of PNAs is restricted by the difficulties of deliver...
متن کاملNucleic acids and protein synthesis in cancer cell mitochondria. I. Nucleic acids in rat hepatoma mitochondria.
The contents of nucleic acids in rat liver and hepatoma mitochondria and the physico-chemical properties on DNA’s isolated from these mitochondria were comparatively investigated. The results are briefly summarized as follows. 1. The contents of DNA and RNA per mg protein of the hepatoma cell mitochondria were about 10 and 2 to 4 times higher than those of rat liver mitochondria, respectively. ...
