Proteins in the DNA sliding clamp family are structurally conserved essential proteins in all three kingdoms of life. Their role in DNA replication and repair is well known, but the recently discovered roles of the eukaryote DNA sliding clamp PCNA in regulation of cellular signaling, cellular metabolism and apoptosis indicate that this family of proteins has additional functions of importance for cellular stress responses. This highlights the clamp family as promising drug targets.

Based on the scientific discovery of the novel PCNA interaction motif, APIM, Otterlei founded the NTNU spin-off company APIM Therapeutics in 2009, and has since then been in charge of the development of a peptide drug containing the APIM sequence for use in cancer therapy as a part time CSO in APIM Therapeutics (https://www.apimtherapeutics.com/). Clinical phase I was finalized in 2021, and the drug, ATX-101, is well tolerated (Lemech et al, 2022 (PMID: 36564469) and show cancer stabilizing activity. Two Phase Ib/II studies are ongoing.

Central studies for understanding of the processes regulated by APIM-PCNA interactions and therefore important for understanding the mode of action of the APIM-peptide drug are:

Basic research exploring the roles of the APIM – PCNA interactions in the regulation of DNA repair (Gilljam et al., 2009 (PMID 19736315) and 2012 (PMID 23152873)), DNA damage tolerance (Ræder et al., 2018 (PMID 30597836) and Seelinger and Otterlei, 2019 (PMID 31973093)) and cellular stress signaling (Olaisen et al, 2015 (PMID 25797046) and 2018 (PMID 29988559)
In vivo anti-cancer effects (animal models) and cellular effects of targeting PCNA with peptides containing APIM (Gederaas et al., 2014 (PMID 25500092), Søgaard et al., 2018 (PMID 29545934) and (PMID 30197755), Søgaard et al., 2019 (PMID 31921382), Røst et al., 2022 (PMID: 36564470).

During studies of the peptide as an anti-cancer drug, an infection in one of the cell cultures lead to the discovery of the peptide’s antibacterial activity. This activity is shown to be linked its interaction with the beta-clamp (Nedal et al. 2020 (PMID 32347931). Recent experiments have shown that the peptide has anti-mutagenic activity, broad activity on multidrug resistant strains from all species on the ESCAPE list, is rapid bactericidal, has anti-biofilm activity, and is difficult to gain resistance against (Nepal et al, 2021 (PMID: 34899646), Sumabe et al, 2021 (PMID: 34198819), Ræder et al, 2021 (PMID: 33815313)).

The research group’s current focus is to further explore peptides targeting the bacterial DNA sliding clamp for anti-bacterial activities.

Select a clinical indication for further development
Explore the beta-clamp’s role outside DNA replication, i.e. elucidate the involvement in regulation of cellular signaling and metabolism
Explore the interaction between the APIM-peptide and its target.

Increase the understanding of the complex roles of the DNA clamp in prokaryotes is important for development of drugs targeting the beta-clamp.

The project “Targeting AMR by inhibition of bacterial stress responses”, TAMiR, (https://www.ntnu.edu/ikom/tamir#/view/about) is one out of four AMR related projects in Norway funded by the Trond Mohn Foundation (TMS) (see: https://mohnfoundation.no/amr-prosjekter/).
