2. 1. Bombesin Antagonists for Targeting Gastrin-Releasing Peptide Receptor-Positive Tumors : Design, Synthesis, Preclinical Evaluation and Optimization of Imaging Agents

   Author : Zohreh Varasteh; Anna Orlova; Roger Schibli; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bombesin; Gastrin-releasing peptide receptor GRPR ; Antagonist; Radionuclide molecular imaging;

   Abstract : This thesis is focused on the development, preclinical evaluation, and optimization of radiotracers for the detection of gastrin-releasing peptide receptor (GRPR)-expressing tumors. The work is divided into three distinct parts: (1) the development of bombesin (BN) antagonist (RM26)-based imaging radiotracers for the detection of GRPR-expressing tumors using different positron emission tomography (PET) and single photon emission computed tomography (SPECT) radionuclides (68Ga, 18F and 111In), (2) the establishment of a method to monitor the ligand-G protein-coupled receptor (GPCR) interaction in real time without requiring purification and stabilization of the receptors, and (3) the evaluation of radiopeptide structure-related factors (length of mini-PEG linker and composition of chelator for metal labeling) affecting the in vitro and in vivo characteristics of RM26-based tracers.

4. 2. Prostate cancer theranostics using GRPR antagonist RM26

   Author : Bogdan Mitran; Anna Orlova; Vladimir Tolmachev; Ulrika Rosenström; Tony Lahoutte; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastrin-releasing peptide receptor GRPR ; Bombesin; Prostate-specific membrane antigen PSMA ; Antagonist; Radionuclide molecular imaging; Theranostics; Peptide receptor radionuclide therapy PRRT .;

   Abstract : The malignant transformation of cells is often associated with an alteration of their molecular phenotype, resulting in overexpression of several cell surface proteins. Gastrin-releasing peptide receptor (GRPR) and prostate-specific membrane antigen (PSMA) are examples of such pro-teins that are expressed at a high density in prostate cancer. READ MORE

5. 3. Theranostic Targeting of GRPR and PSMA in Prostate Cancer

   Author : Ayman Abouzayed; Anna Orlova; Ulrika Rosenström; Anzhelika Vorobyeva; Bogdan Mitran; Cristina Müller; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; gastrin-releasing peptide receptor GRPR ; prostate-specific membrane antigen PSMA ; nuclear medicine; molecular imaging; radiotracers; theranostics; Farmaceutisk vetenskap; Pharmaceutical Science; Oncology; Onkologi;

   Abstract : This thesis is based on five original articles that investigated the theranostics of prostate cancer by gastrin-releasing peptide receptor (GRPR) and prostate-specific membrane antigen (PSMA) targeting. GRPR and PSMA are two extensively evaluated prostate cancer cell markers due to their overexpression in the majority of prostate cancer samples. READ MORE

6. 4. Functional Aspects of Peripheral and Spinal Cord Neurons Involved in Itch and Pain

   Author : Bejan Aresh; Malin Lagerström; Klas Kullander; Martin Schmelz; Uppsala universitet; []
   Keywords : mGluR7; anaphylaxis; Grpr; Penk; Pdyn; Cre line; BAC cloning; spinal cord; transgenic line; Medicinsk vetenskap; Medical Science;

   Abstract : We have investigated the role of the metabotropic glutamate receptor 7 (mGluR7) and the gastrin releasing peptide receptor (Grpr) population that are involved at different levels of itch transmission. We found that mGuR7 deficient mice displayed an anaphylaxis-like behavior when provoked with histamine. READ MORE

7. 5. Targeting and driving somatosensory neurons

   Author : Fabio Freitag; Malin C. Lagerström; Andrew Todd; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pain; Itch; GRPR interneurons; dorsal horn; trigeminal nucleus caudalis; Barrel field;

   Abstract : Pain and itch are two distinct sensations, but the fundamental question of how our nervous system distinguishes the processing and encoding of their related information is still far to be clearly delineated. At the spinal cord level, evidences have pointed out specific groups of neurons expressing the gastrin releasing peptide (Grp) and its receptor (Grpr) as responsible for carrying specifically itch-related information.
