Formation of DNA-protein cross-links involving the initial formation of a guanine radical cation was investigated. For this purpose, riboflavin-mediated photosensitization of a TGT oligonucleotide in aerated aqueous solution in the presence of the KKK tripeptide was performed. We have shown

Polycationic polymers have been used to condense therapeutic DNA into submicron particles, offering protection from shear-induced or enzymatic degradation. However, the spontaneous nature of this self-assembly process gives rise to the formation of multimolecular aggregates, resulting in significant polyplex heterogeneity.

Several injectable materials have been shown to preserve or improve cardiac function as well as prevent or slow left ventricular (LV) remodeling post-myocardial infarction (MI). However, it is unclear as to whether it is the structural support or the bioactivity

Domains rich in cationic amino acids are ubiquitous in peptides with the ability to cross cell membranes, which is likely related to the binding of such polypeptides to anionic groups on the membrane surface. To shed more light on these
