Bent oligonucleotide duplexes as HMGB1 inhibitors: a comparative study

In this work we explore the ability of a chimeric LNA/DNA bent duplex, in which the kink is induced by 2 unpaired adenines in the middle of one strand, to bind HMGB1, a protein involved in many inflammatory processes. The LNA/DNA duplex was compared with the corresponding full DNA and PNA/DNA chimera duplexes from a thermodynamic and spectroscopic point of view.
