    • Mechanisms of antibiotic action shape the fitness landscapes of resistance mutations 

      Hemez, Colin; Clarelli, Fabrizio; Palmer, Adam C.; Bleis, Christina; Abel, Sören; Chindelevitch, Leonid; Cohen, Theodore; Abel zur Wiesch, Pia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-24)
      Antibiotic-resistant pathogens are a major public health threat. A deeper understanding of how an antibiotic’s mechanism of action influences the emergence of resistance would aid in the design of new drugs and help to preserve the effectiveness of existing ones. To this end, we developed a model that links bacterial population dynamics with antibiotic-target binding kinetics. Our approach allows ...
    • Chitosan-based delivery system enhances antimicrobial activity of chlorhexidine 

      Hemmingsen, Lisa Myrseth; Panchai, Pimmat; Julin, Kjersti; Basnet, Purusotam; Nystad, Mona; Johannessen, Mona; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-29)
      Infected chronic skin wounds and other skin infections are increasingly putting pressure on the health care providers and patients. The pressure is especially concerning due to the rise of antimicrobial resistance and biofilm-producing bacteria that further impair treatment success. Therefore, innovative strategies for wound healing and bacterial eradication are urgently needed; utilization ...
    • Nucleic acid peptide nanogels for the treatment of bacterial keratitis 

      Obuobi, Sybil Akua Okyerewa; Mayandi, Venkatesh; Nurul, Azlyn Mohd Nor; Lee, Benedict Jiasheng; Lakshminarayanan, Rajamani; Pui Lai, Rachel Ee (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-14)
      Cage-shaped nucleic acid nanocarriers are promising molecular scaffolds for the organization of polypeptides. However, there is an unmet need for facile loading strategies that truly emulate nature's host–guest systems to drive encapsulation of antimicrobial peptides (AMPs) without loss of biological activity. Herein, we develop DNA nanogels with rapid in situ loading of L12 peptide during the thermal ...
    • How docetaxel entrapment, vesicle size, zeta potential and stability change with liposome composition–A formulation screening study 

      Holsæter, Ann Mari; Wizgird, Kristina; Karlsen, Iselin; Hemmingsen, Jeanette Frimand; Brandl, Martin; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-21)
      Limitations of the anticancer drug product Taxotere® have encouraged researchers to entrap the active ingredient docetaxel (DTX) into nanocarriers such as liposomes. However, until now no DTX-liposome formulation has reached the clinic. Hence, in the present study, different Soy-PC based DTX-liposome formulations were screened in an attempt to identify lipid-compositions with promising DTX-entrapment ...

    • Effect of antiangiogenic therapy on tumor growth, vasculature and kinase activity in basal- and luminal-like breast cancer xenografts 

      Lindholm, Evita Maria; Kristian, Alexandr; Nalwoga, Hawa; Kruger, Kristi; Nygård, Ståle; Akslen, Lars A.; Mælandsmo, Gunhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-03-31)
      Several clinical trials have investigated the efficacy of bevacizumab in breast cancer, and even if growth inhibiting effects have been registered when antiangiogenic treatment is given in combination with chemotherapy no gain in overall survival has been observed. One reason for the lack of overall survival benefit might be that appropriate criteria for selection of patients likely to respond ...
    • Toxicity Assessment of Resveratrol Liposomes-in-Hydrogel Delivery System by EpiVaginal Tissue Model 

      Jøraholmen, May Wenche; Damdimopoulou, Pauliina; Acharya, Ganesh; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-17)
      The natural polyphenol resveratrol (RES) has shown great potential as an antimicrobial, including against microbes associated with vaginal infections. To fully exploit the activities of RES, an all-natural ingredients formulation for RES delivery at vaginal site has been developed, namely liposomes loaded with RES, incorporated into a chitosan hydrogel as secondary vehicle. Although considered ...
    • The pH-Responsive Liposomes—The Effect of PEGylation on Release Kinetics and Cellular Uptake in Glioblastoma Cells 

      Rustad, Eirik André Lindeløff; von Hofsten, Susannah; Kumar, Robin; Lænsman, Eirik Abrahamsen; Berge, Gerd; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-25)
      Nanomedicine has been, to a certain degree, a success story in the development of superior anticancer therapies. However, there are tumors that remain a huge challenge for nanoformulations, for instance, brain tumors such as glioblastoma, the most common and aggressive brain tumor. To utilize the fact that such tumors are characterized by an acidic extracellular environment, we selected pH-responsive ...

    • Crosstalk between p38 MAPK and GR Signaling 

      Zeyen Øyås, Lisa; Seternes, Ole Morten; Mikkola, Ingvild (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-19)
      The p38 MAPK is a signaling pathway important for cells to respond to environmental and intracellular stress. Upon activation, the p38 kinase phosphorylates downstream effectors, which control the inflammatory response and coordinate fundamental cellular processes such as proliferation, apoptosis, and differentiation. Dysregulation of this signaling pathway has been linked to inflammatory diseases ...
    • Studies of synthetic chalcone derivatives as potential inhibitors of secretory phospholipase A&lt;sub&gt;2&lt;/sub&gt;, cyclooxygenases, lipoxygenase and pro-inflammatory cytokines 

      Jantan, Ibrahim; Bukhari, Syed Nasir Abbas; Adekoya, Olayiwola; Sylte, Ingebrigt (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-09-16)
      Arachidonic acid metabolism leads to the generation of key lipid mediators which play a fundamental role during inflammation. The inhibition of enzymes involved in arachidonic acid metabolism has been considered as a synergistic anti-inflammatory effect with enhanced spectrum of activity. A series of 1,3-diphenyl-2-propen-1-one derivatives were investigated for anti-inflammatory related activities ...
