The critical role of spatio-temporal control in combinatorial chemo- and magnetic hyperthermia thermo-therapy: 'the where', 'the how' and 'the when'

Combinatorial treatments hold the key to the future of cancer treatment as they enhance therapeutic indexes by inducing synergistic effects and reducing resistance processes, while often providing a safer option for patients with fewer off-target effects. However, combinatorial treatments bring extra problems to cancer management not only derived from the actual compatibility of the treatments, but also from their hands-on administration. Operational parameters such as administration order and dosing (dose, spacing) have to be optimized in order to positively impact patient prognosis. Here we present a systematic study on the optimization and the importance of these parameters within the framework of a combinatorial chemo-/thermo-therapy. Parameters like where, how and when are investigated in detail. Furthermore, we delve into the underlying biochemical mechanisms driving the observed effects through transcriptome analysis.

Exploring G and C-quadruplex structures as potential targets against the severe acute respiratory syndrome coronavirus 2

In this paper we report the analysis of the 2019-nCoV genome and related viruses using an upgraded version of the open-source algorithm G4-iM Grinder. This version improves the functionality of the software, including an easy way to determine the potential biological features affected by the candidates found. The quadruplex definitions of the algorithm were optimized for 2019-nCoV. Using a lax quadruplex definition ruleset, which accepts amongst other parameters two residue G- and C-tracks, hundreds of potential quadruplex candidates were discovered. These sequences were evaluated by their in vitro formation probability, their position in the viral RNA, their uniqueness and their conservation rates (calculated in over three thousand different COVID-19 clinical cases and sequenced at different times and locations during the ongoing pandemic). These results were compared sequentially to other Coronaviridae members, other Group IV (+)ssRNA viruses and the entire realm. Sequences found in common with other species were further analyzed and characterized. Sequences with high scores unique to the 2019-nCoV were studied to investigate the variations amongst similar species. Quadruplex formation of the best candidates was then confirmed experimentally. Using NMR and CD spectroscopy, we found several highly stable RNA quadruplexes that may be suitable theranostic targets against the 2019-nCoV.
