Abstract

Kidney disease is a complex health problem, often coinciding with cardiovascular pathology (e.g. hypertension) and metabolic disturbances (e.g. obesity and diabetes). It is also a disturbingly fast growing global public health problem, e.g. chronic kidney disease affects an estimated ~9-16% of the population. Besides the public health issues this results in a large economic burden as kidney diseases contributes disproportionally to about a quarter of total health care costs. Experimental and clinical data solidly support the view that kidney tissue hypoxia plays a critical and intricate role during the genesis and progression of both chronic and acute kidney diseases. This research field is currently at the very beginning of integrating pre-clinical with clinical research in which hypoxia related mechanism are quantified by non-invasive imaging. In combination with the fact that some key questions remain unanswered, this offers exciting new research perspectives that are waiting to be explored. With this Research Topic we aim to discuss and find answers to the following research question: 1) What are the temporal relationships between hypoxia and kidney disease? 2) Can we demonstration causation between hypoxia and kidney disease? 3) Can renal hypoxia be considered as a treatment target in kidney disease? 4) Can hypoxia (e.g. in the urine) be considered a biomarker of kidney disease? 5) Does hypoxia ramp-up sympathetic activity? 6) Does hypoxia trigger inflammation? 7) Is hypoxia caused by changes in sodium reabsorption and/or mitochondrial function? 8) Which molecular mechanisms are involved in hypoxia in kidney disease? 9) Which gene expressions change due to hypoxia in kidney disease? 10) Can we generate new and translational insights using non-invasive imaging technologies? Our overall aim is identify the mediators/controllers of hypoxia in kidney disease. If we understand more about the sequence of events leading to hypoxia, its regulation and consequences in renal disease, we might be able to have a major impact in clinical practice. I.e. more accurate and earlier diagnosis, novel treatment targets, and novel therapies.

Abstract

Over the past decades, the field of molecular imaging has been rapidly growing involving multiple disciplines such as medicine, biology, chemistry, pharmacology and biomedical engineering. Any molecular imaging procedure requires an imaging probe that is an agent used to visualize, characterize and quantify biological processes in living systems. Such a probe typically consists of an agent that usually produces signal for imaging purpose, a targeting moiety, and a linker connecting the targeting moiety and the signaling agent.Many challenging problems of molecular imaging can be addressed by exploiting the great possibilities offered by modern synthetic organic and coordination chemistry and the powerful procedures provided by conjugation chemistry. Thus, chemistry plays a decisive role in the development of this cutting-edge methodology.Currently, the diagnostic imaging modalities include Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Ultrasound (US), Nuclear Imaging (PET, SPECT), Optical Imaging (OI) and Photoacoustic Imaging (PAI). Each of these imaging modalities has its own advantages and disadvantages, and therefore, a multimodal approach combining two techniques is often adopted to generate complementary anatomical and functional information of the disease. The basis for designing imaging probes for a given application is dictated by the chosen imaging modality, which in turn is dependent upon the concentration and localization profile (vascular, extracellular matrix, cell membrane, intracellular, near or at the cell nucleus) of the target molecule. The development of high-affinity ligands and their conjugation to the targeting vector is also one of the key steps for pursuing efficient molecular imaging probes. Other excellent reviews, text and monographs describe the principles of biomedical imaging, focusing on molecular biology or on the physics behind the techniques. This Research Topic aims to show how chemistry can offer molecular imaging the opportunity to express all its potential.
