Mechanisms of antibiotic action shape the fitness landscapes of resistance mutations
(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
(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
(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 ... -
Behavior of E. coli ST131 regarding the acquisition of a blaOXA-48 encoding plasmid
(Master thesis; Mastergradsoppgave, 2021-05-11)Antimicrobial resistance has been a challenge ever since the discovery of antibiotics. The rising challenge of resistance has led to the increased use of last-resort antibiotics: carbapenems. It is predicted that a successful E. coli clone, ST131 is apt for the acquisition of carbapenem-resistance encoding plasmids. In this study, we aim to understand how E. coli ST131 respond to acquisition of ... -
Mercaptoalkanol-derived self-immolative linkers for bioconjugates. Synthesis and analysis
(Master thesis; Mastergradsoppgave, 2021-01-11)Many of the anticancer compounds discovered through synthesis or bioprospecting activities are found to be equally toxic to healthy cells and tumors. Consequently, these compounds are not considered as promising drug candidates worthy of further study. This project seeks to develop a novel chemical toolkit that can be utilized to increase the therapeutic value of such toxic compounds by decreasing ... -
Molecular Modelling of PDE3A Catalytic Domain
(Master thesis; Mastergradsoppgave, 2020-05-14)<p>Recent studies have highlighted the clinical benefits of regulating phosphodiesterase-3 enzymes. Inhibition of PDE3A has proven to aid in preventing and treating cardiovascularrelated disorders and platelet dysfunction. Hypothermia is a condition that can cause cardiac arrest. However, there are no suitable inotropic drugs that are effective for use under hypothermic conditions. Being able to ... -
Biofilm-related characteristics in clinical isolates of Extraintestinal Pathogenic E. coli
(Mastergradsoppgave; Master thesis, 2021-05-10)The rapid increase in antibiotic resistance is one of the leading global health issues at present time. Bacteria’s resistance to antibiotic agents can be a thousand times higher when they are embedded in an extracellular biopolymer matrix, defined as biofilm. The biofilm state is a major driver of persistent infections, offering a challenge in providing adequate treatment. Biofilm producing E. coli ... -
How docetaxel entrapment, vesicle size, zeta potential and stability change with liposome composition–A formulation screening study
(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
(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
(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.

Functional analysis of signaling pathways activated by Anisomycin and Dexamethasone in two different breast cancer cell lines
(Mastergradsoppgave; Master thesis, 2022-05-12)While targeted therapy exists for ER-positive breast cancers, the treatment option for TNBC is conventional chemotherapy giving a poorer prognosis. It is therefore of interest to study molecular mechanisms and differences between MCF7 (ER-positive) and MDA-MB-231 (ER, PR, and HER2- negative). These cell lines are in vitro representative models for luminal A (non-aggressive) and basal-like (aggressive) ... -
The pH-Responsive Liposomes—The Effect of PEGylation on Release Kinetics and Cellular Uptake in Glioblastoma Cells
(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 ...
